However, with the advent of the LTE-A and 5G era, the energy consumption of wireless base stations is expected to increase significantly. In the 5G era, the environment of communication base stations is more complex and the requirements are more stringent. It is no longer enough to replace lead-acid batteries with ordinary lithium batteries in energy storage systems. , unable to meet the new needs of the 5G era

[0003] The existing technology mainly has the following disadvantages: due to the high power consumption of 5G equipment, the overall power consumption of the base station increases, and the backup power capacity of the module needs to be upgraded and expanded. Traditional communication base stations use lead-acid batteries or lithium batteries for backup power to expand capacity When upgrading, different types of batteries (lithium battery, lead-acid mixed use) will be used in parallel and mixed, and new and old lithium batteries will be used in combination. Due to the different types and the new and old lithium battery modules, the voltage platform of the module is different. When used directly in parallel, bias current, Circulation and other issues, thereby reducing the capacity utilization and service life of the battery
