Why do lithium batteries need a BMS?
Overcharging or discharging a lithium-ion battery can shorten its life and even cause safety hazards. A BMS prevents this by automatically disconnecting the battery from the charger or load when it reaches unsafe levels, safeguarding the battery and preventing potential damage.
What does BMS mean in a battery?
At its core, BMS stands for Battery Management System. It's an essential component for lithium-ion batteries, which are commonly used in electric vehicles (EVs), energy storage systems (ESS), and other devices that require rechargeable batteries.
What is battery management system (BMS)?
BMS is an essential device that connects the battery and charger of EVs . To boost battery performance and energy efficiency, BMS is controlled by critical aspects such as voltage, state of health (SOH), current, temperature, and state of charge (SOC), of a battery .
Do li-ion batteries need a battery management system?
Nowadays, Li-ion batteries reign supreme, with energy densities up to 265 Wh/kg. They do, however, have a reputation of occasionally bursting and burning all that energy should they experience excessive stress. This is why they often require battery management systems (BMSs) to keep them under control.
What is a BMS & why is it important?
If the voltage becomes too high or too low, it can damage the battery and reduce its lifespan. The BMS ensures that the battery stays within a safe voltage range, optimizing its performance and longevity. The State of Charge (SOC) is a measurement that indicates how much charge is left in the battery.
What are the components of a battery management system?
It consists of the control unit, battery status estimation, data acquisition, safety protection unit, battery monitoring unit, and thermal management unit [, , , , ]. Fig. 6. Functional blocks of the battery management system. 2.1.1. Control unit It encompasses the complete electronic power control system of the BMS.
