Components of the TP4056 Module

TP4056 IC:

Key elements of the module is charge of overseeing the charging procedure. To guarantee a secure and effective charge, it regulates the voltage and current sent to the battery. The integrated circuit contains functions to prevent overcharging, regulate heat, and perform proper charge termination.

 

Protection Circuitry:

Contributes to the continuity and safety of batteries and modules. By keeping the battery from being charged above its maximum capacity, this avoids overcharging. Damage from unintentional short circuits can be avoided with the use of short circuit protection. The battery can not overdischarge, however, thanks toover-discharge safeguards.

 

Indicator LEDs:

Gives a visual indication of the charging status Essentially, there are two LED lights: one for charging indications. A completely charged battery is indicated by two lights, one of which is often red. (Typically, green or blue) The user can simply keep an eye on the charging process thanks to these LED lights.

 

Micro-USB or Type-C Input:

This connector makes it simple to utilize the module with a standard USB charger, power bank, or computer USB port by enabling it to be linked to a USB power source. Depending on the particular module model, Micro-USB or Type-C can be chosen; Type-C provides a more contemporary and flexible connection option.

 

Pinout

-BAT+ and BAT-: Attach to the battery's positive and negative terminals.

-IN+ and IN-: Attach to the power supply's positive and negative terminals (typically 5V).

-OUT+ and OUT-: During battery charging, these pins are connected to a load that can receive electricity straight from the battery.

 

Working Principle

How the TP4056 Module Charges Batteries

The TP4056 module regulates the voltage and current supplied to the battery in order to oversee the charging process. It aids in making sure the battery is charged effectively, safely, and to its maximum capacity without going overboard. This module allows the attached lithium ion battery to be charged under control by connecting it to a power supply by Micro USB or Type C input.

 

Stages of Charging

Constant Current (CC) Stage:

The TP4056 module gives the battery a steady current in this initial stage. Usually set to a default value (such 1A), the current can be changed by adjusting the on-board resistor's value. The battery voltage will progressively rise during this process.

 

Constant Voltage (CV) Stage:

The module switches to a constant voltage level when the battery voltage hits a predefined threshold, which is typically 4.2V for a single-cell lithium-ion battery. The module keeps the voltage constant in this step, allowing the charging current to progressively rise. As the battery gets closer to its maximum capacity, it falls. In addition to helping to securely charge the battery, this stops overcharging.

 

Trickle Charge (or Taper Charge) Stage:

The Module cuts off its current at a very low level when the battery is almost fully charged. Sometimes this procedure is referred to as trickle charging. It will guarantee that the battery is stress-free and fully charged. The TP4056 integrated stops charging when the current falls below the designated threshold, at which point the battery is deemed fully charged.
