Abstract

The invention relates to a test method of a whole automotive electric balance. The test method comprises the following steps of: measuring voltages and currents of an automotive storage battery, a power generator and automotive electrical components by using a data acquisition unit and a current sensor; measuring an electricity quantity of the storage battery by using a storage battery tester; during dynamic electric balance test, discharging the electricity of the storage battery until the electricity quantity is 50 percent of a rated capacity before the test to make the automobile in a running state, testing for 4 to 5 hours, and testing whether the whole automobile is in the dynamic electric balance according to the variation of the electricity quantity of the storage battery before and after the test or an average current ratio of a charging current to a discharging current of the storage battery; during static electric balance test, measuring a static current, a lowest starting capacity, a general available capacity and a self-discharging current of the storage battery, and obtaining a static parking time period of the automobile by calculation so as to realize the test of the static electric balance.

Description

Technical field

[0001] The invention relates to a test method for the electric balance of an automobile. Background technique

[0002] The generator is the power source of the car circuit, the battery is the energy storage device, and the on-board electrical appliance is the load. Due to the different working conditions of the car, the engine speed changes all the time, making the generator's power generation capacity constantly change. At the same time, because the car electrical appliances are used in different states, the total current consumed is also different, making the electrical load also different . The battery is an energy storage mechanism. When the generator's generating capacity cannot meet the needs of the consumer, it is discharged to provide the load for use. When the generator's generating capacity exceeds the needs of the consumer, the generator supplements the battery to charge, so that the generator, battery It forms a dynamic balance with electrical applia...
