Abstract

The embodiment of the invention relates to the technical field of battery management, in particular to an SOC display method and system for a cascaded BMS and an electronic device, and aims to solve the problem that the corresponding BMS electric quantity is increased or decreased due to voltage rise after BMS charging and voltage drop after BMS discharging, so that difference fitting is performedon the maximum SOC value in the cascaded BMS and the SOC display value of a cascaded system in different states. And in combination with the charging current / discharging current of the cascaded BMS,the incremental electric quantity / decrement electric quantity of the cascaded BMS is obtained, so that the SOC display value of the cascaded BMS can be truly reflected.

Description

technical field [0001] The embodiments of the present application relate to the technical field of battery management, and in particular to an SOC display method, system and electronic equipment of cascaded BMSs. Background technique [0002] With the shortage of energy, rising oil prices, and increasingly serious urban environmental pollution, the development and utilization of new energy alternatives to oil has been paid more and more attention by governments, such as solar energy, wind energy, thermal energy and other renewable energy sources. Land energy storage has been developed rapidly because it can effectively adjust the uncertainty and instability of renewable energy, and realize large-capacity storage. However, there are few applications for marine energy storage energy supply. Ocean energy storage supply needs to put the battery pack on the seabed, so it cannot be salvaged frequently, which requires large-capacity energy storage. The cascading BMS system increas...
