Two-wheel drive distributed hub driving pure electric vehicle temperature adjusting and controlling system

Abstract

The invention discloses a two-wheel drive distributed hub driving pure electric vehicle temperature adjusting and controlling system. The system is mainly composed of an oil tank, an oil pump, hub motors, wheels, a storage battery, a heater, a radiator, a fan, temperature sensors, a controller, a coarse strainer, a fine strainer, four-way valves, two-way valves and the like. The system receives temperature signals fed back by all the temperature sensors through the controller, and an instruction is sent to control the oil pump, the heater and the radiating fan to be started or stopped as well as control opening and closing of openings of all valve bodies, so that under different working conditions, different circulation accesses are connected to enable cooling oil to flow in the corresponding accesses. The two-wheel drive distributed hub driving pure electric vehicle temperature adjusting and controlling system can achieve integrated cooling and heat dissipation of the storage battery and the hub motors and can also heat the storage battery during low-temperature starting, thus, the storage battery can work with the optimal temperature range as far as possible, the working performance of the storage battery is achieved better, and the service life of the storage battery is prolonged.

Description

technical field [0001] The invention relates to a temperature control system for a pure electric vehicle, in particular to a temperature control system for a type of two-wheel drive distributed hub-driven pure electric vehicle. Heat the battery, make the battery work in the best temperature range as much as possible, better play the working performance of the battery and prolong its service life. [0002] technical background [0003] The increasingly serious energy and environmental crisis has brought enormous pressure to traditional vehicles. Therefore, the development of ultra-low-emission or zero-emission electric vehicles has become an important way to solve this problem. There is no doubt that pure electric vehicles are the best way to achieve zero emissions. Countries around the world also regard pure electric vehicles as one of the focuses of research and development, especially pure electric vehicles driven by in-wheel motors because of their simplified overall layo...

Problems solved by technology

However, under the current technology, the energy density of power batteries used in pure electric vehicles is low, and the working temperature range of vehicle motors and battery packs is relatively narrow. However, my country has a vast territory and the climate and environment vary greatly, resulting in pure electric vehicles. driving in specific urban environments

[0004] As far as the temperature control system of pure electric vehicles driven by in-wheel motors is currently commonly used, it can basically only cool the in-wheel motors, but not preheat the battery pack. Therefore, the battery pack can only work in areas with high ambient temperature. Cannot be used in alpine regions
