A 3s BMS wiring diagram is a diagram that shows how to connect a 3s (3-cell) battery management system (BMS) to a 3-cell lithium-ion battery pack. It illustrates the proper wiring connections between the BMS and the battery cells.
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.
To make a battery pack, the first step is to know the nominal voltage of a cell. The cells selected by us have a nominal voltage of 3.7Volts while the charge voltage is 4.2V. So, in order to make a 12 V pack, we require 3 cells connected in series. The image of cells we used is shown below We are selecting a 3.7V battery with a capacity of 1200mAh.
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.
The electrical circuit consists of the cells, the PCM, and the load. The protection circuit is responsible for monitoring the state-of-charge (SOC) of the battery and limiting the current, the voltage, and the temperature of the battery. Li-ion battery packs are highly efficient and offer a long life cycle.
The electrical path to pull up the battery pack VCC passes through the host capacitance from Pack+ to Pack–, through a substrate diode in the host interface driver from VSS to the commu-nication or interface line, and through a substrate diode from this line to VCC in the battery-pack circuitry. The complete path is shown in Fig. 6.
Connecting cells in Series: When the positive terminal of one battery is connected with the negative terminal of the second battery, the battery is considered to be connected in a series connection.
