Abstract
The invention provides a thermal management method of an electric automobile and a vehicle. The method comprises the steps: in a vehicle navigation mode, obtaining a navigation route of the vehicle according to the current position of the vehicle and a preset destination position, and segmenting the navigation route to obtain a plurality of navigation road sections; acquiring current environment information of the vehicle and a current vehicle running state; acquiring a thermal management control strategy from a preset thermal management control strategy library according to the road condition corresponding to the next navigation road section of the vehicle, the current environment information and the current vehicle running state; and adopting a thermal management control strategy in the next navigation road section, and controlling a thermal management system of the vehicle correspondingly. By segmenting the navigation route and monitoring the vehicle state and environment information, the optimal thermal management control strategy of each road section is found out, and segmented thermal management control is realized, so that energy can be effectively saved, the energy utilization rate is improved, the endurance mileage of the vehicle is improved, and a guarantee is provided for the achievement of the target mileage.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a thermal management method of an electric automobile and the vehicle. Background technique [0002] As the world's environmental protection issues and energy crisis become more and more prominent, new energy electric vehicles with the characteristics of saving fuel energy, low exhaust emissions, less pollution, and low noise have become the goal pursued by people. At present, the development and popularization of electric vehicles are facing many challenges. For example, electric vehicles currently use thermal management systems and air-conditioning heat exchange to dissipate heat from batteries, and heat power batteries at low temperatures, mainly using PTC to heat power batteries. The existing thermal management methods do not take into account the actual situation during driving, which leads to energy waste in the thermal management system of the vehicle, low energy utili...
