The battery management system is mostly equipped with the corresponding database management system of battery operation and charging data to evaluate the battery performance. The data support is provided by the optimal design of batteries for application to the market.
Although the battery management system has relatively complete circuit functions, there is still a lack of systematic measurement and research in the estimation of the battery status, the effective utilization of battery performance, the charging method of group batteries, and the thermal management of batteries.
Relevant system states, such as the state of energy (SOE) of the string, are transmitted to the battery management system (BMS). The BMS is the central control unit of the BESS responsible for communicating with other units in the container.
Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:
Therefore, for full management with multiple strings, one BMS unit must be used per string, and in some cases, a master controller must be used to manage the whole pack.
