How BMS Works on Batteries in EV: Boosting
Whether it''s Lithium-Ion, Nickel-Metal Hydride (NiMH), or any other battery type, the BMS monitors key factors like voltage,
Like lead-acid batteries, lithium batteries can be permanently damaged by overcharging, deep discharging, or extreme temperatures. That's where the Battery Management System (BMS) comes in. Often called the brain of the battery, the BMS ensures your batteries operate safely, efficiently, and for as long as possible. In this guide, we'll cover:
The BMS prevents your lithium battery's voltage from going too high (causing overheating and gas release) or too low (leading to permanent damage). Damage occurs if you overcharge (cell voltage gets too high) or over-discharge (cell voltage gets too low) a lithium-ion battery cell. Overcharging occurs when recharging exceeds a battery's safe range.
Sensors: BMS relies on various sensors to monitor the state and performance of the battery cells and pack. Examples include: voltage monitoring, current sensors, temperature sensors, and impedance sensors.
Microcontrollers: A BMS typically uses microcontrollers to manage the battery cells and pack, and to communicate with external systems and devices. Infineon AURIX microcontrollers such as TC3xxx and Traveo T2G family of microcontrollers can be used to develop and deploy BMS.
