Abstract

The invention provides a method and a device for controlling an automobile storage battery, wherein the method comprises the following steps: within a preset state-of-health (SoH) area of the storage battery, performing state-of-charge (SoC) partitioning on a capacity of the storage battery in a fully charged state to obtain a plurality of SoC subintervals; monitoring a first SoC value of the storage battery and determining the SoC subinterval corresponding to the first SoC value; and then judging a current running state of the automobile, determining a control mode of the storage battery according to the current running state of the automobile and the SoC subinterval corresponding to the first SoC value, and executing processing corresponding to the control mode. As a result, comprehensive monitoring and protection on various working conditions of the storage battery are realized according to the service condition characteristics of the automobile storage battery. The method has the advantages of reasonably planning and designing automobile power utilization, preventing over discharge of the storage battery, realizing insufficient voltage protection of the automobile-mounted storage battery and ensuring the starting capability of the automobile.

Description

technical field [0001] The invention relates to battery technology, in particular to a method and device for controlling an automobile battery. Background technique [0002] With the rapid development of automotive electronic and electrical technology, more and more comfort and entertainment appliances are used in automobiles, such as air conditioners, heated seats, massage seats, etc. The car battery is gradually unable to meet the increasing energy demand, and it is very easy to over-discharge the battery, causing the car to fail to start, and at the same time causing damage to the battery and reducing its service life. [0003] Therefore, there is an urgent need for a vehicle battery control method to reasonably allocate power usage according to the state of battery power. Contents of the invention [0004] The invention provides a control method and device for an automobile storage battery. By monitoring the state of charge of the storage battery, the control mode of ...
