BMS Battery Storage System：
Battery energy storage systems are placed in increasingly demanding market conditions, providing a wide range of applications. Zhilin spend years and know how to build a battery management system (BMS) that ensures long lifetimes, versatility and availability.
Every modern battery needs a battery management system (BMS), which is a combination of electronics and software, and acts as the brain of the battery. The most basic functionalities of the BMS are to make sure that battery cells remain balanced and safe, and important information, such as available energy, is passed on to the user or connected systems.
Balancing is needed because battery systems are made up of hundreds, sometimes thousands of individual cells, which all have slightly different capacities and resistances. These differences increase over time as the cells degrade at different rates. If the cells are not balanced at least occasionally, their voltages will soon drift apart to an extent that the battery capacity becomes unusable.
Safety is ensured by keeping the cells within safe operating limits of voltage, current and temperature, which is particularly important for lithium-ion batteries. If cells get over-charged, charged at very low temperatures, or exposed to excessive currents or temperatures, they could develop faults that may lead to fires or explosions.
> Charging disconnected when the overall voltage reaches the preset value.
> BMS single cell charging for dual protection, and a 2nd layer protection is activated if the 1st simulated charging fails. The BMS is UL certified for abnormal charging and abusive overcharge tests.
>Over temperature protection, the charging is disconnected when the battery cell is out of 50+/-5℃ range or below 0℃.
> PTC protection,disconnected automatically when charging current is abnormal.
> Over-discharge protection
> Over-current protection
> Short circuit protection
