A 12 meter electric bus typically requires 6-8 battery packs, each containing thousands of individual units connected in parallel (series). It can be imagined how to coordinate and orderly carry out the work of battery systems with numerous individual battery organizations with certain differences? It's very simple, organized, there must be management, and a battery management system is generated.

　　Single cell batteries are objects, and of course, those who manage battery work are also objects, not people. This object is naturally a computer management system. In summary, Battery Management System (BMS) is an intelligent management system that utilizes computer technology.

　　Working process of lithium-ion power batteries:

　　During the charging and discharging process, lithium ions continuously move back and forth between the positive and negative poles through the electrolyte passing through the separator. The number of lithium-ion batteries returning to the moving house cannot be reduced or increased, and it must be controlled. If the control is good, the battery can be repeatedly charged without reducing its capacity, otherwise it will cause a permanent decrease in battery capacity, or even explode.
