What is a Battery management?

Battery Management System (BMS) is a system that monitors and controls the state of a battery to maximize its performance and ensure its longevity. It is particularly crucial in high-performance battery systems like lithium-ion batteries to prevent risks such as overcharging, overdischarging, and overheating.

The BMS monitors parameters such as the state of charge (SOC), voltage, and temperature of the battery. It also performs functions like cell balancing, fault diagnosis, overload protection, and optimizing power supply, improving the overall efficiency of the system. This helps prevent premature battery aging due to overuse or uneven usage and enhances energy efficiency.

BMS is widely used in electric vehicles (EVs), renewable energy systems, smartphones, and other mobile devices, playing a key role in ensuring battery safety and performance.

Application of Battery management

１．Electric Vehicles (EVs)
In EVs, the BMS monitors the battery's charge state, voltage, and temperature to ensure optimal performance. It prevents overcharging and overdischarging, extending battery life and maximizing driving range.
２．Residential Solar Power Systems
In solar power systems, the BMS efficiently manages the energy stored in batteries. It monitors the state of charge and controls charging and discharging as needed, ensuring a stable power supply for the home.
３．Smartphones
Smartphones equipped with lithium-ion batteries also use BMS to monitor battery health, preventing overcharging and ensuring optimal battery lifespan.
