The Li-ion battery pack circuit diagram consists of three basic components: the battery cells, the PCM, and the load. The cells are the primary energy source for the system, providing the energy for the load. The PCM is responsible for monitoring and protecting the battery from overcharging, over-discharging, and excessive temperature.
A Li-ion battery pack is composed of individual cells connected in series or parallel with a protective circuit module (PCM). The PCM is designed to protect the battery from overcharging, over-discharging, and excessive temperature. It is also responsible for monitoring the state-of-charge (SOC) of the battery.
The PCM is usually placed between the cells in a series configuration and is responsible for balancing the cells, controlling the charging and discharging rates, and monitoring the state-of-charge (SOC) of the battery. The Li-ion battery pack circuit diagram can be divided into two parts: the electrical circuit and the protection circuit.
If the circuitry in the battery pack contains a substrate diode from the communication line to VCC, it is possible to disrupt the VCC supply when plugging in the battery pack. This disruption may cause improper operation of the battery-pack electronics.
Always use a charger specifically designed for li-ion cells. Avoid charging the battery in extremely hot or cold environments. Never leave the battery unattended while charging the li-ion cell. Charge the battery in a safe, non-flammable area to mitigate any potential risks. Part 4. How to discharge li-Ion cells?
The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery’s lifespan.
