Abstract

The invention discloses a bench durability test verification device and method for a 48V hybrid power system of an automobile. The bench durability test verification device includes a dynamometer, a dynamometer, a bench control unit, a rapid prototype controller, and a 12V storage battery; The machine is connected with the dynamometer, the bench control unit and the engine respectively; the rapid prototype controller is connected with the engine control module, the motor control module, the lithium battery control module and the DC conversion control module respectively; the 12V battery is connected with the DC converter. The invention can verify the function of the 48V hybrid power system of the automobile on the bench.

Description

technical field [0001] The invention belongs to the automobile testing technology, and in particular relates to an automobile 48V hybrid power system bench durability test verification device and method. Background technique [0002] Due to regulations on CO 2 Emission restrictions are becoming more stringent and hybrid systems are being used more and more in vehicles. The hybrid system is divided into micro-hybrid, medium-hybrid, pure electric and plug-in hybrid according to electrical function / capacity. Generally speaking, the higher the voltage level, the more fuel consumption can be saved, but the vehicle weight, electrical structure and electrical cost are also increased accordingly. [0003] The 48V hybrid system has the functions of energy recovery, power assist and low-speed electric driving during driving, and can contribute to a reduction in fuel consumption of about 10%. In addition, since the 48V hybrid system is a low voltage level, the weight and cost of the...
