Abstract
Description
Technical Field
[0001] The utility model relates to a test and verification system for intelligent charging function and a new energy vehicle, belonging to the technical field of automobiles. Background Art
[0002] With the increasing complexity of vehicle electrical systems, the factors affecting the static power consumption of the whole vehicle also increase, and the vehicle battery is more likely to have a power shortage phenomenon. Compared with traditional fuel vehicles, new energy vehicles have more controllers, so the static current of new energy vehicles is larger when parked, and the battery is more likely to have a power shortage phenomenon. To solve the problem of battery power shortage, many current new energy vehicles have added an intelligent charging function. When the controller monitors that the voltage of the whole vehicle is lower than the set critical value, it automatically charges the battery.
[0003] Although adding an intelligent charging function to the whole vehicle can effectively avoid the occurrence of battery power shortage in the vehicle, there may still be functional deviations and inconsistencies with the design in the actual operation of the intelligent charging function. Therefore, it is necessary to carry out system function test and verification simultaneously. The traditional test and verification methods mostly turn on high-power loads to consume the battery power. When the voltage approaches the opening voltage critical value of the intelligent charging function, the key is powered off, and then the vehicle is placed statically, relying on the static current to continuously consume the battery power until its voltage reaches the design critical value, and the execution of the intelligent charging function is verified through a multimeter and a network test device. The test cycle of the traditional test and verification method is uncontrollable and the operation is complex, seriously affecting the test and verification efficiency. Summary of the Invention
