Technical FAQs 4

What are overvoltage and undervoltage protection?

Overvoltage protection and undervoltage protection are essential features in battery management systems (BMS) designed to maintain battery health and safety.

What is overvoltage protection in battery management systems?

Understanding Overvoltage Protection in Battery Management Systems Overvoltage protection is a safety mechanism that prevents a battery from being charged beyond its maximum voltage rating. This is crucial because excessive voltage can lead to overheating, reduced battery life, or even catastrophic failure such as thermal runaway.

What is the difference between overvoltage and under voltage alarm?

BMS (1039) 09/03/2021 1. Increase the alarm conditions of overvoltage and under voltage of the battery. Overvoltage alarm requires two cells to reach 3.65, or one cell to reach 3.9, while under voltage alarm means two cells to reach 2.6 or one cell to reach 2.3. 2. Increase the protection conditions of overvoltage and under voltage of the battery.

What are the changes in a battery overvoltage alarm?

1.Battery overvoltage alarm changed from 3.6V to 3.65V. 2.The undervoltage and overvoltage time changed from 1s to 15s. 3.Optimized 80 %DOD calculations (previously only released 78 %). 4.Triggered low Pressure If no overpressure is triggered within 4 days, the low pressure mark will be removed.
