Abstract

The invention belongs to the technical field of vehicles, particularly provides a vehicle power distribution method, device and system, a vehicle and a vehicle-mounted controller, and aims at solvingthe problems that in the prior art, power battery energy distribution is not reasonable enough, and the comfort requirements of a user cannot be met. In order to achieve the purposes, the vehicle power distribution method comprises the following steps: determining energy supply equipment according to the current operation condition of the vehicle; comparing the available output power of the energysupply equipment with the whole vehicle required power of the vehicle, and determining a state type of the vehicle under the current operation condition according to the comparison result; and distributing power to energy consumption parts of the vehicle according to the power distribution strategy corresponding to the state type. Based on the steps, the method provided by the invention has the beneficial effects that the power can be reasonably distributed to the maximum extent, the energy utilization rate is improved, and user experiences are improved.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a vehicle power distribution method, device, system, vehicle and vehicle-mounted controller. Background technique [0002] A pure electric vehicle is a vehicle driven by a power battery. The power battery also provides energy for the vehicle accessories. Due to the limitation of the power battery energy storage and charging facilities, the power battery may not be able to meet the needs of the vehicle at the same time in the case of long-term use. Energy requests for electric motors and high-voltage accessories. [0003] In the prior art, the energy distribution strategy is relatively simple, and the energy management is only performed for the driving state of the vehicle, but there is no corresponding energy distribution strategy for the charging state. In addition, there are few types of high-voltage accessories considered for the energy distribution of high-volta...
