The BMS is a smart device. Pins on the battery connector include:

A standard laptop BMS circuit generally consists of three primary Integrated Circuits (ICs): laptop battery bms circuit

This is a low-speed, 100kHz communication bus derived from I2C. The laptop's embedded controller (EC) reads data from the BMS via SMBus: The BMS is a smart device
