Automobile power supply management system

Abstract

The invention relates to a power supply management system. The system comprises a monitoring unit and a control unit, wherein the monitoring unit is used for monitoring parameters of a storage battery and simply analyzing the parameters; and the control unit comprises an analyzing unit and a processing unit; the analyzing unit is used for receiving, analyzing and judging parameter information monitored by the monitoring unit; and the processing unit is used for receiving instructions of the analyzing unit and sending corresponding processing information. The system is characterized in that: early warning, quiescent current management and the charge-discharge management of the storage battery are performed by the processing unit, wherein the quiescent current management includes non-anti-theft current management when an automobile is switched off and anti-theft current management when the automobile is stopped. The application state of electrical appliances of the whole automobile, and the power generation power and the output voltage of a power generator are controlled by monitoring the state of the storage battery, and the state information of the storage battery is provided for a driver, so that the electrical balance of the whole automobile is optimized to the largest extent.

Description

[0001] This application is a divisional case of patent application 200710145921.7, and all content in the application of 200710145921.7 is cited in this divisional case. technical field [0002] The invention relates to a power management system, in particular to an automobile power management system. Background technique [0003] 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 affec...

Problems solved by technology

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.
