How Mobile Phone Charging Technology Works

Mobile phone charging technology has become an essential part of our daily lives. Understanding how this technology works can help users make better choices regarding their devices and charging habits. This article delves into the mechanics of mobile phone charging, covering traditional wired charging, fast charging, and wireless charging.

Traditional Wired Charging

Traditional wired charging is the most common and oldest method of charging mobile phones. It involves connecting a charger to the phone via a USB cable. The process begins when the charger is plugged into an electrical outlet. Here's a step-by-step look at how it works:

Power Source: The charger is connected to a power source, typically a wall outlet. The charger converts alternating current (AC) from the outlet into direct current (DC), which is suitable for battery charging.

Power Transfer: The DC power is transferred through the USB cable to the mobile phone. Inside the phone, the charging port receives this power and directs it to the battery.

Battery Charging: The battery management system (BMS) in the phone regulates the amount of power sent to the battery to prevent overcharging and overheating. Lithium-ion batteries, commonly used in phones, charge through a two-phase process: constant current (CC) and constant voltage (CV). During the CC phase, the battery receives a steady current until it reaches a set voltage. Then, during the CV phase, the current decreases as the voltage remains constant until the battery is fully charged.

Fast Charging

Fast charging technology has gained popularity due to the increasing demand for shorter charging times. It works by delivering higher power levels to the phone's battery. Here’s how it differs from traditional charging:

Increased Power Output: Fast chargers supply more power (measured in watts) compared to standard chargers. This is achieved by increasing the voltage and/or current. For instance, a traditional charger might provide 5 watts (5V/1A), while a fast charger can deliver 18 watts or more (9V/2A or 12V/1.5A).

Optimized Battery Management: Phones equipped with fast charging technology have advanced BMS that can handle higher power inputs safely. These systems monitor the battery's temperature and charge level to adjust the power flow, ensuring efficient and safe charging.

Enhanced Charging Protocols: Various fast charging standards exist, such as Qualcomm Quick Charge, USB Power Delivery (PD), and proprietary technologies like Apple's Fast Charge or Samsung's Adaptive Fast Charging. These protocols determine the power levels and communication between the charger and phone to optimize charging speed and safety.

Wireless Charging

Wireless charging offers a convenient way to power up mobile phones without the need for cables. It uses electromagnetic fields to transfer energy between two coils: one in the charging pad and the other in the phone. Here’s how it works:

Inductive Charging: The most common type of wireless charging, inductive charging, relies on electromagnetic induction. When the phone is placed on the charging pad, an alternating current passes through the pad's coil, generating a magnetic field. This magnetic field induces a current in the phone's coil, converting it back into DC power to charge the battery.

Resonant Charging: A less common but emerging technology is resonant charging. It allows for more flexibility in positioning the phone on the charging pad. It operates on similar principles but uses resonant inductive coupling, which enables energy transfer over greater distances compared to inductive charging.

Efficiency and Convenience: While wireless charging offers convenience, it is generally less efficient than wired charging due to energy loss in the form of heat. However, advancements in technology are continuously improving the efficiency and speed of wireless charging.

Conclusion

Understanding how mobile phone charging technology works can help users make informed decisions about their devices and charging practices. Traditional wired charging, fast charging, and wireless charging each have their mechanisms and benefits. As technology advances, we can expect even more efficient and faster charging solutions to become available, further enhancing the user experience.

Power Supply for Espressif Module with Battery Charger & Boost Converter

We will discuss the integration of a power supply for the ESP32 Board. Additionally, we will add a Boost Converter Circuit to enable the use of a 3.7V Lithium-Ion Battery for powering the ESP32. Since Lithium-Ion Batteries can discharge, we will integrate a Battery Charger Circuit along with a Battery Management System. Many Lithium-Ion/Lithium Polymer Batteries can only charge up to 4.2V, which is low for the ESP32 Board.

Therefore, we need to increase the battery voltage from 2.8V-3.7V to 5V. This necessitates the use of a compact Boost Converter Module build with inductors, ICs, and resistors. To facilitate battery charging and management, we will use the TP4056 Battery Charger Module. Alternatively, we can also power the circuit using a 9V/12V DC Adapter. The LM7805 Voltage Regulator IC restricts the voltage to 5V. If you are not going to use a battery for power, you can utilize the DC Power Adapter or a 9V Battery.

ESP32 Power Requirement

The ESP32 Board’s operating voltage is between 2.2V to 3.6V. But we can supply 5V from the Micro-USB port. For applying 3.3V there is already an LDO voltage regulator on the module to keep the voltage steady at 3.3V. ESP32 can be powered using Micro USB port and VIN pin (from external supply).

The power requirement of ESP32 is 600mA of that ESP32 pulls only 250mA during the RF transmissions. When it is performing boot or wifi operation it’s drawing more than 200mA current. Thus supplying power from Micro-USB Cable is not enough for ESP32 Board when we need to add multiple sensors or modules to the Board. This is because Computer USB port can provide less than 500mA of current. Check more on power requirements of ESP32 here ESP32 Datasheet.

Hardware Requirements

Following are the components required for making this ESP32 Power Supply project. You can get all the components from our Campus Component store.

ESP32 Board-ESP32 ESP-32S Development Board (ESP-WROOM-32)

Battery Charger Module-TP4056 5V,1A Battery Charging Module

Voltage Regulator IC-LM7805 5V IC

Female DC Power Jack-DCJ0202

Step-Up Boost Converter Module-3.7V to 5V Boost Converter Module

Switch-3 Pin SPDT Switch

Electrolytic Capacitor-470uF, 25V

Electrolytic Capacitor-100uF,16V

LED-5mm LED Any Color

Resistor-220 ohm

3.7V to 5V Step-Up Boost Converter Module

The above shown is the Step-Up DC-DC Boost converter module which provides 5V DC stable voltage output for various input ranges between 1.5V to 5V. This small tiny circuit boosts the voltage level and provides the amplified stabilized 5V output. This module operates at a frequency of 150KHZ. It utilizes varying amounts of current to generate a balanced output for different input ranges.

2. Input 1.5-2V, output 5V 100-150mA

3. Input 2-3V, output 5V 150-380mA

4. Input more than 3V, output 5V 380-480mA.

TP4056 Battery Charger Module

The TP4056 module is designed specifically for charging rechargeable lithium batteries through the constant-current/constant-voltage (CC/CV) charging technique. Apart from ensuring the safe charging of lithium batteries, the TP4056 BMS Board incorporates essential protection mechanisms for lithium batteries. It is compatible with both USB power and adapter power supplies. Also because of its internal PMOSFET architecture and anti-reverse charging path, there is no need for external isolation diodes.

TP4056 Module Datasheet.

Power Supply for ESP32 with Battery Charger & Boost Converter

The circuit can be powered by using two methods, one with 9V/12V DC Adapter and other with 3.7V Lithium-Ion Battery.

To power the board through the DC Jack, we've added here a DCJ0202 Female Jack. Also we have added 470uF and 100uF Electrolytic Capacitors that serve to lower the DC fluctuations and eliminate voltage spikes. The LM7805 Voltage Regulator IC is capable of handling input voltages ranging from 7V to 35V, although it's advisable to stay within the 15V limit. Higher input voltages result in increase in heat dissipation thus we have to add a larger heat sink. Connecting the Voltage regulator's output to the Vin pin of the ESP32 and grounding it ensures the module can be powered using a 9V/12V DC Adapter or a 9V Battery.

Alternatively, if opting not to utilize a DC Adapter for ESP32 power, a 3.7V Lithium-Ion or Lithium Polymer Battery can be used. Utilizing the Boost Converter Module, the 3.7V is increased to 5V, operating within the 2.8V to 4.2V input range. The boosted 5V is connected to a switch, and the switch is linked to the 5V Vin pin of the ESP32. The Battery terminal is also connected to the output terminal of the TP4056 Battery Charger Module, allowing the battery to be charged using a 5V MicroUSB Data Cable.

Conclusion

Thus by including a Battery Charger and Boost Converter to power up the esp32, we can create a flexible and efficient power for the unique requirements of the ESP32 platform. Reach out to the Campus Component- an electronics parts suppliers today, if you are building a Battery charger, Boost converter and looking for electronic components such as ESP32 and other microcontrollers from trusted brands such as Mornsun, Espressif, AIT, IKSEMI other components.
