This series BMS is mainly design for 48V with less than 30A and 20A discharging and charging current lithium battery group. In this scheme, a low power with high precision processor is used to match the high accurately sampling chip for dynamic intelligent management of battery pack. This series applied the unique SOC & SOH algorithm, which can elvaluate the higher accurate SOC for large capacity battery packed. At the same time, the intelligent dynamic equalization to ensure the lithium batteries work in a stable state and prolong the life of batteries.
The 2G & GPS module accomplish the data transaction among the battery packed and iclould server. Then the server keep track the working condition of the battery group on time. It can judge the SOH of battery pack and alarm the user once the battery in abnormal status. At the same time, the GPS function can track the location of battery group on time.
