Battery management system BMS, mainly manages the charge and discharge protection of the battery pack. When fully charged, it can ensure that the voltage difference between each single battery is less than the set value, so as to achieve the equal charging of each single battery in the battery pack, which effectively improves the charging effect under the series charging method. The BMS system is supplied with the lithium-ion battery as a set.
The energy management system EMS is mainly to monitor the real-time operation status information of the power station, including system power curve, battery voltage and temperature information, accumulated processing power information and other agreed monitoring information. And it can establish remote monitoring software and download data in the server, capable of real-time alarm and transmission to designated cell phones.
