Title:
BALANCING METHOD AND DEVICE FOR ENERGY STORAGE BATTERY MANAGEMENT SYSTEM AND ENERGY STORAGE BATTERY MANAGEMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/157534
Kind Code:
A1
Abstract:
A balancing method and device for an energy storage battery management system and an energy storage battery management system. The balancing method comprises: collecting the battery parameter of each single battery in at least one battery module, each battery module comprising a plurality of single batteries in series, and one or more signal batteries in series serving as a power supply source of the energy storage battery management system; and performing charge/discharge balancing, on the basis of a balancing strategy, on all battery modules according to the battery parameters, the balancing strategy being that the total quantity of power of the balance discharging of all the battery modules being greater than the total quantity of power of the balance charging of all the battery modules. The balancing method of the energy storage battery management system is to select N single batteries in series among the batteries of the energy storage battery management system to serve as the power source of the system so as to supply power to circuit boards of the energy storage battery management system and the like. Meanwhile, the balancing method reduces the cost of an additional UPS by adjusting the balancing strategy. In addition, since the capacity of the cell of a single battery is much greater than the capacity of the cell of the UPS, the power source of the system is more stable.
