Vehicle power management system

Abstract

The invention relates to an automobile power supply management system. Firstly, by monitoring the state of the storage battery, the application state of an electrical apparatus used in an entire automobile is controlled, simultaneously the generation power and the output power of a generator is controlled, and the state information of the storage battery is provided to a driver, thereofore maximally optimizing the electric balance of the entire automobile; besides, the static current of the entire automobile is controlled, and the consumption of the electric quantity of the storage battery caused by the static current is reduced, ensuring the time for normally starting after the automobile stops, as well as optimizing the charging and discharging state of the storage battery and prolonging the service life of the storage battery.

Description

technical field [0001] The invention relates to a power management system, in particular to an automobile power management system. Background technique [0002] At present, automotive electronics technology has developed to a new stage of control system integration and information sharing. The large increase in electrical components and control units has led to an increase in the load power of the vehicle, increasing the demand for electric energy; if the use of electric energy cannot be well managed and controlled, it may be due to the insufficient power supply of the generator, resulting in The battery supplies power to the outside world. If the battery discharge time is too long, the battery power will be insufficient, which will affect the normal starting and safe driving of the vehicle, and even affect the service life of the battery. The large increase in electrical components and control units also increases the difficulty of static current control. If the static cur...

The large increase in electrical components and control units has led to an increase in the load power of the vehicle, increasing the demand for electric energy; if the use of electric energy cannot be well managed and controlled, it may be due to the insufficient power supply of the generator, resulting in The battery supplies power to the outside world. If the battery discharge time is too long, the battery power will be insufficient, which will affect the normal starting and safe driving of the vehicle, and even affect the service life of the battery.

The large increase in electrical components and control units also increases the difficulty of static current control. If the static current of the vehicle cannot be well controlled, the parking time of the vehicle will be affected, and even the regulatory requirements of some markets cannot be met.
