Four-wheel drive hub drive blade electric vehicle power assembly temperature integrated regulation and control system

Abstract

The invention discloses a four-wheel drive hub drive blade electric vehicle power assembly temperature integrated regulation and control system. The system is mainly composed of an oil tank, an oil pump, a hub motor, wheels, a storage battery pack, a heater, a radiator, a fan, a controller, temperature sensors, a coarse filter, a fine filter, a four-way valve, a three-way valve, a two-way valve and the like. According to the system, real-time temperature signals fed back by the temperature sensors are received by the controller, and the controller is sent to control starting and stopping of the oil pump, the heater and the fan and control opening and closing of valve openings of all valves; and under different working conditions, different circulation passages are closed to enable cooling oil to flow in corresponding passages. By means of the four-wheel drive hub drive blade electric vehicle power assembly temperature integrated regulation and control system, integrated cooling and radiating of the storage batteries and the hub motor can be achieved; and during low-temperature starting, the storage batteries can be heated, the storage batteries can work within the best temperature scope as many as possible, the working performance of the storage batteries is better played, and the service life of the storage batteries is prolonged.

Description

technical field [0001] The invention relates to a temperature control system for a pure electric vehicle, in particular to an integrated temperature control system for a powertrain of a four-wheel-drive wheel hub-driven pure electric vehicle. The battery can be heated to make the battery work in the optimum temperature range as much as possible, so as to better play the working performance of the battery and prolong its service life. [0002] technical background [0003] Due to the depletion of oil resources and the improvement of public awareness of environmental protection, automobile factories around the world are engaged in the development of new energy vehicles, especially pure electric vehicles. However, the development of pure electric vehicles is currently restricted by key technologies such as batteries and motors, such as battery energy density, driving range, and battery operating temperature; and the current pure electric vehicles are only suitable for driving in...

Problems solved by technology

[0004] As far as the currently commonly used in-wheel motor-driven pure electric vehicle powertrain temperature integrated control system is concerned, basically it can only cool and dissipate the in-wheel motor to ensure its normal operation; it cannot guarantee the normal operation of the battery pack in low-temperature and harsh environments. Since the battery pack can only work in a specific temperature environment, the use of pure electric vehicles is also limited to this
