Test system and method based on electric vehicle charging

Abstract

The invention discloses a test system and method based on electric vehicle charging, and the system comprises an industrial personal computer; the high-voltage direct-current power supply, the high-voltage direct-current load, the low-voltage direct-current power supply, the low-voltage direct-current load, the alternating-current power supply, the signal simulator, the CAN communication equipment and the data acquisition equipment are connected with the industrial personal computer; the test equipment is respectively connected with the to-be-tested product; the to-be-tested product at least comprises a vehicle-mounted charger integrated DCDC assembly. According to the technical scheme provided by the embodiment of the invention, function testing can be carried out on various products including the vehicle-mounted charger integrated DCDC assembly, the problems that in the prior art, the testing product and the testing mode are single, and various different working conditions in actual use of an automobile cannot be covered are solved, various tested products can be compatible, various working modes are covered, and the testing efficiency is improved. The practicability of the test system provided by the embodiment of the invention is further improved, and large-scale popularization is facilitated.

Description

Technical field [0001] The invention relates to the field of new energy vehicles, in particular to a test system and method based on electric vehicle charging. technical background [0002] New energy vehicle refers to the use of unconventional vehicle fuels (except gasoline and diesel) as power sources, especially pure electric vehicles. With the vigorous promotion and popularization of pure electric vehicles, the demand for core components such as battery modules and on-board charger has obviously increased. [0003] At present, the test schemes for on-board charger or DCDC are mature in the industry, but with the development of integration technology, the two-way on-board charger integrated DCDC assembly for electric vehicles is gradually applied to vehicles. The existing test schemes can only test the single charger module and the single DCDC module, and cannot cover the actual operating conditions of vehicles. Inventive content [0004] The embodiment of the invention provi...

Problems solved by technology

[0003] At present, the test schemes for function and performance testing of on-board chargers or DCDC are relatively mature in the industry, but with the development of integrated technology, DCDC assemblies integrated with two-way on-board chargers for electric vehicles are gradually being applied to vehicles. The test scheme can only be tested for a single charger module and a single DCDC module, and cannot cover the actual working conditions of the vehicle
