New energy automobile thermal management system test device

Abstract

A new energy automobile thermal management system test device comprises: a condenser environment chamber containing condenser parts and used for simulating the working environment of a real automobile condenser; an evaporator environment chamber which contains evaporator parts and is used for simulating the working environment of an evaporator of a real vehicle; a power battery environment chamber which contains a power battery and is used for simulating the working environment of the power battery of a real vehicle; The electric drive system environment chamber accommodates an electric drive system, a compressor, a battery cooler and a heater and simulates the working environment of the electric drive system; By simulating the working modes of an air conditioning system, battery thermal management and electric drive thermal management on a whole vehicle in various environments, the combined matching test of the whole vehicle level thermal management system is carried out, and the mismatching problem of the thermal management systems is avoided; By carrying out the matching test of the subsystems, the resource allocation reasonability of each system can be improved, the energy consumption and efficiency of the whole vehicle and the comfort of passengers can be improved, all thermal management systems do not need to be built, even the whole vehicle does not need to be waited for carrying out related tests, and test resources are saved.

Description
