Introduction

In automotive applications, Domain Controllers are a specialized computer that manages a set of vehicle functions within a specific area, or domain. Functional domains that typically need a domain controller require substantial computing power and are connected to numerous input/output (I/O) devices. Examples include active safety, user experience, and body and chassis functions.

Radars, cameras, and other sensors around the car provide inputs to an active safety domain controller, which then uses that data to build a model of the surroundings. Based on what the model indicates, software programs in the domain controller subsequently decide “policy and planning” what the vehicle should do. For instance, based on pre-set regulations, the software may use sensor-generated images to identify a pedestrian who will cross the road and trigger the car to either apply the brakes or warn the driver.

Types of Domain Controllers in Vehicles

According to their functional domain, domain controllers in the automotive sector usually fall into one of several major categories:

Powertrain Domain Controller: In charge of controlling the car’s engine, gearbox, and additional propulsion and power systems. These controllers are essential for maximizing performance, emissions, and fuel economy. Powertrain domain controllers regulate the motor, battery, and energy flow in electric cars.

Chassis and Body Domain Controller: These controllers regulate the vehicle’s body features like door locks, climate control, and lighting as well as its physical dynamics like steering, braking, and suspension. The vehicle’s comfort and safety are enhanced by chassis and body domain controllers.

Active Safety Domain Controller: Made to interpret information from radar, cameras, and sensors to make safety judgments in real-time. This domain controller is crucial for features like adaptive cruise control, automated emergency braking, and lane-keeping because it builds a model of the environment around the car.

Information entertainment and user experience Domain controllers are in charge of the infotainment system, instrument cluster, and other controls that interact with passengers, such as the navigation and climate systems. These controllers facilitate functions that improve the user’s engagement with the car, resulting in a smooth and joyful experience.

Why are Domain Controllers Essential?

Several factors are driving the growing use of domain controller in automobiles:

Complexity Reduction: As cars get more features, there are more electronic control units (ECUs), which makes the wiring system more complex. By combining many ECUs into a single, central controller, domain controllers simplify the wiring harness of the car and increase durability.

Increased Processing Capacity: As automobile technology has developed, cars now need a significant amount of processing power. The power required to manage complicated activities, such as processing radar data for active safety features or operating high-definition graphics for infotainment systems, is provided by domain controllers, which are tuned for certain functions.

Reduced Manufacturing Costs: Automakers can reduce costs related to components, wiring, and software development by reducing the number of ECUs by combining various functions into a single controller. Because fewer ECUs need to be integrated and deployed, domain controllers also expedite the production process.

Software Update Facilitation: Continuous enhancement of vehicle performance and features is made possible by over-the-air (OTA) software upgrades, which are made possible by a centralized controller configuration. As manufacturers remotely send out new features and safety improvements, OTA updates are becoming more and more valuable.

Domain Controllers and the Evolution of E/E Architecture

Because they enable further centralization and standardization of vehicle functions, domain controllers are fundamental to the development of automotive electrical/electronic (E/E) architecture. Conventional E/E designs are made up of dispersed ECUs that are each in charge of a certain task and are located throughout the car. But as car technology has developed, this model has grown unwieldy, necessitating a more efficient strategy.

Functions can be organized into discrete domains with domain controller, each of which is controlled by a strong controller. This is a big step toward a centralized computing model, in which almost all vehicle operations are managed by one or more powerful computers. It is anticipated that manufacturers will keep combining domain controller into a single computing platform in the future, which would streamline the design of the car, cut down on wire, and improve processing power.

Smart Vehicle ArchitectureTM (SVA), which aims to create a centralized E/E architecture based on domain controllers and central computer units, is a well-known illustration of this approach. Increased connection, enhanced energy efficiency, and scalable software-driven features — all crucial for electric and driverless cars — are made possible by this strategy.

Introduction

The drivetrain of an electric vehicle is called an EV Powertrain, and it is made up of important parts such as an electric motor, battery, and energy management system.

This article gives a general schematic of an electric powertrain and lists the components that make up the EV Powertrain.

The fundamental parts of a vehicle’s powertrain are in charge of producing and transferring power so that it can move forward. It transforms energy into motion by serving as the mechanical core.

EV Powertrains use electric motors driven by rechargeable batteries instead of conventional powertrains, which use internal combustion engines that run on gasoline or diesel. As a result, there are no emissions from the tailpipe and the engine runs smoothly.

EV Powertrain Components

Battery Pack: The electric motor is powered by the battery pack, which is the main component of an electric vehicle. It is composed of many lithium-ion cells.

Electric Motor: Using a stator, rotor, and other essential components, an electric motor transforms electrical energy into mechanical energy to move the car forward. It improves acceleration and overall performance by providing immediate torque and great efficiency.

Traction Inverter: An electric motor’s alternating current (AC) is produced by a traction inverter, which changes the direct current (DC) from the battery pack. It also modifies the frequency and amplitude of the AC to control the motor’s speed and torque.

DC/DC Converter: Transforms the battery pack’s high-voltage DC into the lower-voltage DC needed for the car’s accessories and other systems. The onboard charger transforms AC power from the electrical grid into DC power to charge the battery pack safely and effectively.

Battery Management System (BMS): Manages the charging and discharging cycles to optimize performance and safety while keeping an eye on the health of the battery pack.

Gearbox: By doing away with the need for intricate multi-speed gearboxes, some EVs have direct drive systems or single-speed transmissions, which streamline the EV Powertrain and increase economy.

Actuator: Actuators regulate the operation of the electric motor and open and close valves, among other EV duties.

Electric Controller Units (ECUs): ECUs control how much electricity goes from the battery to the motor, varying torque and speed to get the best results.

Thermal Management System: This system, which often uses water or oil cooling, controls the temperature of EV Powertrain components to preserve longevity and efficiency.

How Do EV Powertrains Operate?

The Power Generation System, the Power Distribution System, and the Mechanical System are the three main systems that make up the EV Powertrain system.

1. Power Generation System

The battery pack and the related management parts are part of the power-creating system. Electrical energy is stored in the battery pack, which is normally composed of lithium-ion cells. By controlling the charging and discharging methods, the Battery Management System (BMS) ensures safe and effective operation by keeping an eye on the health and efficiency of the battery. The electric motor and other parts of the electric car are powered by this system, which serves as its energy source.

2. Power Distribution System

The power control module and the inverter, or DC-AC converter, make up the power distribution system. For the electric motor to run, direct current (DC) from the battery must be converted into alternating current (AC) via the inverter. The power control module controls the flow of electricity, modifying the frequency and amplitude of the AC to control the motor’s speed and torque. This guarantees optimal vehicle performance and effective power distribution.

3. Mechanical System

The drivetrain, gearbox, and electric motor are all part of the mechanical system. The vehicle is propelled by the electric motor, which transforms electrical energy into mechanical energy. The transmission system effectively distributes power from the motor to the wheels; it is often a single-speed gearbox. The car may then move because the drivetrain transfers this mechanical energy to the wheels. Regenerative braking is another feature of some sophisticated systems that allows energy to be recovered during braking and fed back into the battery.

Types of EV Powertrain

1. Battery Electric Vehicle (BEV) Powertrain

Description: BEVs are fully electric vehicles that rely solely on a battery to power an electric motor.

Components:

Battery Pack

Electric Motor

Inverter (DC-AC converter)

Single-Speed Transmission

Battery Management System (BMS)

On-Board Charger

Operation: The battery stores electrical energy, which powers the electric motor to drive the vehicle. There are no internal combustion engine components in a BEV, resulting in zero tailpipe emissions.

Example: Tesla Model 3, Nissan Leaf.

2. Plug-in Hybrid Electric Vehicle (PHEV) Powertrain:

Description: PHEVs are similar to HEVs but have a larger battery that can be charged externally, enabling short-range all-electric travel. Components: Engine with internal combustion (ICE) Electric Motor Larger Battery Pack (compared to HEVs) Inverter On-board charger Transmission Operation: PHEVs may drive short distances entirely on electricity by using their batteries as power. The ICE starts working when the battery runs out. The battery can be charged using regenerative braking, the ICE, or via an external charger. Example: Chevrolet Volt and Mitsubishi Outlander PHEV.

3. Fuel Cell Electric Vehicle (FCEV) Powertrain

Description: FCEVs produce electricity by the use of a hydrogen fuel cell, which drives an electric motor. Components: Hydrogen Fuel Cell Electric Motor Small Battery Pack (for energy buffering) Hydrogen Tanks Operation: The fuel cell’s oxygen and hydrogen storage tanks combine to produce energy. FCEVs are zero-emission cars since the electric motor is powered by electricity, and the only by-product is water vapor. Examples: Toyota Mirai, Hyundai Nexo.

4. Extended Range Electric Vehicle (EREV) Powertrain:

Description: EREVs are similar to BEVs, but they also contain a small gasoline engine that serves as a generator to replenish the battery when it runs low. Components: Electric Motor Battery Pack Small Gasoline Engine (as a generator) Inverter Transmission Operation: The car is driven by an electric motor, and the gasoline engine simply produces electricity to increase the battery’s range. Example: BMW i3 REx.

The cleanest and most energy-efficient options are offered by fully EV Powertrains, such as BEVs and FCEVs. Each type of EV Powertrain offers a different balance between electric and internal combustion energy.

Conclusion:

An important development in automobile technology is the EV Powertrain, which offers a more effective and sustainable substitute for conventional internal combustion engines. The electric powertrain, which consists of vital parts including the battery pack, electric motor, traction inverter, and energy management systems, transforms electrical energy stored in the vehicle into mechanical energy, allowing it to travel smoothly and emit-free.

Battery Electric Vehicles (BEVs), Plug-in Hybrid Electric Vehicles (PHEVs), Fuel Cell Electric Vehicles (FCEVs), and Extended Range Electric Vehicles (EREVs) are the four different types of EV Powertrains, and each has specific benefits and capabilities. While BEVs and FCEVs are recognized for their zero-emission performance, PHEVs and EREVs give flexibility by incorporating conventional engines to extend range and versatility.

The Crucial Role of On-Board Charger Function

September 30, 2024

Autonomous Vehicle Technology

Edit

Introduction

The On-Board Charger (OBCs) market for electric vehicles is expected to develop at a compound annual growth rate (CAGR) of 22.4% from 2020 to 2027, reaching $10.82 billion globally. By obtaining an average 25% improvement in DC-DC rating and almost 30% reduction in charging time, Electra EV has been making significant improvements in OBC technology, thus expanding electric mobility applications and meeting end-user expectations.

What Is an On-Board Charger?

Furthermore, by enabling it to convert DC power from the high-voltage battery back to AC power, the OBC is essential to bidirectional charging. This can power AC loads (V2L), feed energy into the grid (V2G), and even charge other electric vehicles (EVs).

Enabling faster AC charging

EV manufacturers can satisfy consumer needs for faster charging while minimizing battery degradation because of advancements in OBCs. Constant voltage and constant current are the two charging modes available on AC chargers. Constant voltage, sometimes referred to as trickle charging, is slower but permits complete charging and provides more control over the battery than constant current, which charges the battery more quickly but cannot fully charge it. OBCs use constant voltage toward the conclusion of the charging process, switching from constant current at first to maximize efficiency.

Single-phase and three-phase onboard chargers are the two primary varieties. The normal capacity of a single-phase OBC is between 7.2 and 11 kW, however, a three-phase OBC can have a capacity of up to 22 kW. How quickly the car charges depends in large part on the capacity of the OBC.

The fastest option for consumers is DC fast charging, which sends direct power straight to the battery without using the OBC at all. With capacities ranging from 50 kW to 300 kW, standard DC charging stations provide more than six times the capacity of single-phase OBCs. On the other hand, three-phase OBCs’ larger capacity enables users to maximize AC charging efficiency while reducing battery wear because AC charging is kinder to batteries.

A system-level approach

Several safety features are built into onboard chargers to safeguard consumers and provide the operational safety needed for vehicle applications. These include creating a separation between external hardware and internal components to lower the chance of an electrical failure and automatically cutting off power if the load exceeds operational restrictions. Cybersecurity is especially crucial since the OBC, when connected to the EVSE controller, functions as a high-speed data gateway between the car and the grid.

From the inlet to the battery. One such product is a three-phase On-Board Charger that satisfies numerous automotive-grade data and charging requirements, including the Home Plug, V2G, and ISO 26262 functional safety standards.

To provide cutting-edge, integrated grid-to-battery-pack charging systems that satisfy the strictest performance, safety, cyber security, and power criteria.

Role of On-Board Charger

Controlling the flow of electricity from the grid to the vehicle’s traction battery is the main goal of an onboard charger (OBC), which enables electric vehicles to be charged from any power source. Consequently, depending exclusively on charging facilities is no longer necessary.

When charging a battery, the OBC also regulates the voltage and current levels. Constant voltage and constant current are the two basic forms of charging. Because there is a chance of overcharging, constant current charging might cause battery degradation even though it delivers great efficiency and rapid charging. Conversely, continuous voltage charging can cause a spike in current to first enter the battery.

To solve these problems, the battery is usually charged with constant voltage initially, shifting to constant current after an established charge level is reached. The most important purpose of an electric vehicle’s onboard charger is this charging approach.

Role of OBC in AC Charging

The Battery Management System (BMS) uses the On-Board Charger (OBC) to charge the battery during AC Level 1 and Level 2 charging. The OBC transforms grid AC electricity into DC power. The OBC is in charge of controlling the voltage and current during the charging process. The power output of AC charging does, however, reduce with increasing charging time.

Role of OBC in DC Charging

In DC fast charging, or Level 3 charging, AC power from the grid is directly converted to DC within the charger and supplied to the battery pack. As shown in the diagram, the DC charger has an integrated AC/DC converter, eliminating the need for the onboard charger (OBC) in this type of charging. This reduces charging time. The EVSE is organized into stacks to deliver high current, as a single stack cannot provide the necessary power. Therefore, the OBC has no role in DC charging.

Types of On-board Chargers

EV on-board chargers come in two primary varieties:

On-board single-phase charger

On-board charger in three phases

This classification is based on how many phases the charger can use. A three-phase OBC can generate up to 22 kWh, while a single-phase OBC typically produces between 7.2 and 7.4 kWh. It is possible for the OBC to automatically identify the kind of input it is connected to. When operating in a single phase, the charger can handle 110–260V AC; when operating in three phases, it can manage 360–440V AC. The output voltage applied to the battery is between 450 and 850 volts.

Working on an Onboard Charger

High-power AC input is converted to DC power and Power Factor Correction (PFC) is provided in OBCs that use rectifiers. A PFC circuit removes harmonic distortion from the supply current, resulting in a current waveform that is very similar to a sine wave and improving the power factor to unity. This charger part determines whether the device can operate on one, two, or three phases of AC electricity. The DC/DC converter additionally isolates the power grid from both the high-voltage (HV) and low-voltage (LV) DC buses for safety reasons.

A 700V output voltage is received by the system’s second phase, which drives a transformer by being square-waved and chopped. The transformer subsequently generates the necessary DC voltage. An isolated CAN bus, which is guaranteed by digital isolators or digital isolators with integrated DC/DC power converters, allows for the monitoring and control of the complete system. Ultimately, the necessary voltage is applied to the battery.

Design Considerations for OBCs

Key factors to consider when designing onboard chargers (OBCs) include:

1. The suitable output levels and the AC input 2. The battery pack’s maximum power capacity 3. Minimizing space and maximizing cooling 4. Charging time requirements 5. Power Factor Correction (PFC) and AC signal rectification 6. Connection of the EVSE with the EV 7. Ensuring the battery and power source are safely isolated

Benefits of On-Board Charger

Enhancing Charging Efficiency

Reducing the time required to recharge an electric car by maximizing charging efficiency is one of the main objectives of the onboard charger. On-board chargers reduce energy loss and maximize charging speeds by efficiently converting AC power from the charging station into DC power for the battery. As a result, EV owners may enjoy driving without emitting any emissions for longer and spend less time waiting for their cars to charge.

Adaptive Charging Technologies

Adaptive charging technologies are widely used by modern on-board chargers to increase efficiency. Thanks to these technologies, the charger can interact with the charging station and dynamically change settings in response to many criteria, including voltage levels, temperature, and battery state of charge. Onboard chargers ensure that the battery receives the optimal charging rate for its condition by rapidly optimizing the charging process in real-time, improving efficiency, and extending battery life.

Conclusion:

In conclusion, the onboard charger is essential for optimizing electric vehicle charging efficiency. By effectively converting AC power from charging stations into DC power for the vehicle’s battery, onboard chargers reduce energy losses and enhance charging speeds. The use of adaptive charging systems and ongoing improvements in EV technology bode well for the future of charging electric vehicles. On-board chargers will continue to lead the way in EV charging infrastructure innovation and efficiency as we transition to a more sustainable future.
