Energy control method and energy control system for vehicle high-voltage accessories

Abstract

The present invention provides a vehicle high-voltage accessory energy control method and an energy control system. The energy control method includes the following steps: according to the battery information of the power battery output by the battery controller, when it is judged that the running state of the vehicle is a normal mode, According to the driver's request information on the human-computer interaction system, the vehicle controller controls the high-voltage accessories to perform power distribution; wherein, the request information includes the defrosting request, the driver's rapid acceleration drive request and the vehicle's drive request. request power. Real-time monitoring of power battery information, when it is judged that the power battery reports the trigger function safety threshold or the power battery reports fault information, the power distribution of high-voltage accessories is limited in time.

Description

Technical field [0001] Energy management Technical Field The present invention relates to an electric vehicle, and particularly relates to a high energy of the vehicle accessory control method and for realizing the control method of the energy of the power control system. Background technique [0002] With the continuous development of new energy technologies, electric vehicles account for new car production is growing. Since the electric vehicle is powered by a battery when traveling, a high pressure compressor accessories such as air conditioners, electric heaters and to provide comfort for the driver to provide a cooling system for a battery when the power is consumed, resulting in reduced vehicle mileage, therefore accessory control method of the high-pressure high demands. [0003] Annex prior art high-voltage power control method, the vehicle runs in the normal mode, the driver is not required to consider the defrosting, the battery power is not considered functional safety...

AI Technical Summary

Problems solved by technology

Since electric vehicles are powered by power batteries when driving, high-voltage accessories such as air-conditioning compressors and electric heaters will consume electric energy when they provide a comfortable environment for the driver and provide cooling for the battery system, resulting in a reduction in the cruising range of the vehicle. High-voltage accessory control method puts high demands

[0003] In the energy control method of high-voltage accessories in the prior art, when the vehicle is running in the normal mode, the defrosting requirements of the driver are not considered, and the design requirements of the functional safety of the power battery are not considered

At the same time, the energy control method of high-voltage accessories in the prior art does not consider the driver's comfort requirements, nor does it consider the scene where the power battery of the electric vehicle reports failure.
