Abstract

The invention provides an automotive storage battery monitoring method and system. The method comprises a power-lack data recording process and a power-lack reason determining process. When an automobile is powered on, the voltage value of a storage battery is obtained and whether the storage battery lacks power or not at current is determined according to the voltage value of the storage battery; if the storage battery is in a power-lack state, the current time and voltage value are stored; when the vehicle state is changed, the current time and the remaining capacity of the storage battery are obtained and stored; and the power lack reason is determined according to the stored related data. Since power-lack data of the automobile at different states are stored respectively, the reason why the storage battery has power lack can be determined according to the recorded power-lack data, which is simple and rapid and facilitate the improvement by the user according to the reason of power lack.

Description

technical field [0001] The invention relates to the technical field of electronic control, in particular to a method and system for monitoring an automobile storage battery. Background technique [0002] At present, the battery capacity of conventional fuel vehicles is relatively limited. For example, a 12V battery is generally 45Ah to 70Ah. In addition, there are other factors. For example, when the user does not start the engine of the vehicle, the electrical appliances work for a long time or multiple electrical appliances work at the same time, etc., it is easy to cause the vehicle to lose power. damage the battery. [0003] The most common failure mode of lead-acid batteries in automobiles is the sulfation of the battery plate caused by power loss, but whether the battery loss is caused by improper use by the user, or because of insufficient power generation by the vehicle's generator, etc., due to the user There is randomness in the use process of , and there is no e...
