Abstract

The invention discloses a system for preventing overdischarge of automobile starting battery, comprising a starting battery, a generator and a starting load; the system for preventing overdischarge of automobile starting battery is provided with an overdischarge control unit, and the overdischarge control unit is respectively connected with the starting battery, the generator and the starting load by a signal circuit. The invention also discloses a control method of the system. By adopting the technical scheme, monitoring on automobile starting battery terminal voltage, batter charging current and discharging current and battery working temperature is utilized to judge the actual charge state of the battery and compare the actual electricity quantity with rated electricity quantity, so as to judge whether the battery is overdischarged or not, and corresponding steps are taken like compensate electric quantity charging, the battery is avoided to overdischarge, the battery is ensured to operate normally, and further safety performance of automobile is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile electrics, and relates to a safety protection technology of an automobile starting storage battery. More specifically, the invention relates to a system for preventing over-discharge of an automobile starting storage battery. In addition, the present invention also relates to the control method adopted by the system. Background technique [0002] In recent years, with the rapid development of new technologies of electronics and information, more and more electronic products are being used or will be used in automobile products to improve the comfort, operation stability and safety of cars. The cost of automotive electronics accounts for an increasing ratio of the cost of the entire vehicle, and this ratio even reaches 30%-40% in foreign high-end cars. [0003] The large increase in electrical components and control units has led to an increase in the load power of the vehicle, increasing the d...
