Problems solved by technology

Invention CN106451999A discloses a liquid-cooled electric eddy current retarder and retarder heat utilization system, which effectively realizes the timely cooling of the retarder and reduces the phenomenon of braking heat decline, and avoids the power consumption caused by heating. However, the eddy current retarder used by it consumes a lot of power, which will also reduce the cruising range of the vehicle, and the split structure of the motor and the retarder is costly and takes up a lot of space

Description

technical field [0001] The invention relates to an integrated slow heating integrated motor system for an electric vehicle, which belongs to the field of electric vehicle braking. Background technique [0002] Electric vehicles have the characteristics of safety, environmental protection and energy saving, and are one of the best ways to solve the problems of oil resource shortage and air pollution. Compared with ordinary cars, large electric vehicles such as electric buses, buses and trucks have longer daily driving time and mileage, and consume more resources. Therefore, the development of large electric vehicles is more meaningful for the realization of national energy conservation and emission reduction goals . [0003] One of the bottlenecks currently restricting the development of electric vehicles is the energy problem. In winter, ordinary fuel vehicles can use the waste heat of engine combustion to heat up, while the heating method of electric vehicles is mainly he...
