Abstract

A DC backup source power supply guarantee and battery protection system of the invention belongs to the field of power pool. The system comprises a main control unit, a power supply unit, a charging unit, acquisition control units, a background operation system, and a remote transmission interface. The DC backup source power supply guarantee and battery protection system of the invention can disconnect a single battery which is about to be over-charged or over-discharged from a battery pack to implement effective protection. Power supply guarantee is emphasized. By increasing power sources (DC / DC), energy stored in the single batteries connected to the system can be all released, and the time of power supply can be extended. With the system used, the service life of the protected batteries can be increased, the batteries can be maintained and repaired online, and peak-shifting power utilization can be realized. The system can exit automatically under failure of a single battery. When the system fails, the original backup power supply function of the battery pack is not affected.

Description

technical field [0001] The invention belongs to the field of power pools, and in particular relates to a DC backup power supply guarantee and battery pack protection system. Background technique [0002] Batteries are widely used in military, aerospace, communications, transportation, new energy storage, finance, industrial and agricultural production and many other fields, and the total usage of batteries is huge. Due to manufacturing differences and non-standard use, the actual service life of batteries in some industries is lower than the design life, and far lower than the theoretical life, thus causing serious resource costs and heavy environmental burdens. The reasons that affect the service life of the battery are the use of the battery beyond the specified ambient temperature and the overcharging, over-discharging, and undercharging of the battery. [0003] The material of the battery determines the natural properties of the battery. Usually, the voltage of a single...
