Lithium batteries, however, have serious drawbacks: firstly, safety performance is poor, and almost all kinds of lithium batteries are overcharged or overdischarged to cause irreversible damage to the battery cell. Lithium batteries are also extremely temperature sensitive: if the electrolyte is used under the condition of overhigh temperature, the electrolyte can be decomposed, burnt and even exploded; the low temperature will cause the performance of the lithium battery to deteriorate obviously, and the normal use of the device is affected. Therefore, a set of targeted lithium battery management system must be provided for the lithium battery, and english is: battery Management System, abbreviated BMS, chinese for effective monitoring, protection, energy balance and fault alarm of the Battery pack, thereby improving the working efficiency and service life of the entire lithium Battery.
