Abstract

The invention relates to passenger car power supplies, in particular to an intelligent power supply management system for a passenger car. A first current sensor module, a voltage sensor module and a temperature sensor module are arranged to detect the charging and discharging current, the work voltage and the temperature of a storage battery correspondingly, a second current sensor module is used for detecting the whole car electricity utilizing current, and a circuit protecting module is used for timely disconnecting a corresponding power supply loop under the abnormal conditions such as large current overloading, voltage shortage and overvoltage; and a battery charging and discharging control module is used for controlling an electric generator to charge the storage battery. A power supply management main control module is internally equipped with a storage battery charging state algorithm, according to the temperature of the battery, the battery capacity is corrected, and on the basis of battery characteristic data and real-time detecting data, the charging state is calculated by combining an open circuit voltage method and an ampere-hour integral method. The power supply management system achieves sharing of information and resources with other control units through a CAN bus, and data of the power supply management system are transmitted to a background database and can be used for further data mining, battery loss analysis and failure prediction.

Description

technical field [0001] The invention relates to a passenger car power supply, in particular to an intelligent power supply management system for a passenger car. Background technique [0002] As people have higher and higher requirements for the safety, comfort and humanization of passenger cars, more and more electronic safety equipment and entertainment electrical equipment are carried by passenger cars; on the other hand, in order to improve the environmental pollution of the city, in In the field of public transportation, vigorously promote the use of hybrid and pure electric buses and other new energy buses. All of these put forward higher requirements for the power management system of passenger cars. [0003] The power management system of the bus is responsible for the power distribution, circuit protection and circuit control of the whole vehicle. It is the guarantee for the safety and normal use of various electrical equipment on the vehicle. Its performance direc...
