Cooling device, and fuel tank is flowed back to Jing after valve port b flows through battery, the second two-port valve, coarse filter after the second cross valve confluxes.
7. according to claim 1 two distributed wheel hub driving pure electric automobile temperature regulation system is driven, it is characterised in that
When motor temperature sensor and Battery temperature probe detect respectively first wheel motor and the second wheel hub motor and
When the temperature of battery is the 5th temperature (such as more than the threshold value of its normal work), controller is according to the motor temperature for receiving
The signal of the signal and Battery temperature probe of degree sensor, sends instruction and starts oil pump, send instructions to the first four-way
Valve opens valve port a, b, c, d, while instructing the second cross valve to open valve port a, c, d, close port b simultaneously opens the first two-port valve,
This kind of operating mode lower heater is closed all the time, and so, cooling oil Jing fuel tanks in the presence of oil pump flow out, through fine filtering
Device enters the valve port b mouths of the first cross valve, and Jing its valve port a mouths, d mouths, c mouths point three branch roads flow separately through first wheel electricity
The cooling device of machine, the second wheel hub motor and battery, wherein flow through first wheel motor and the second wheel hub motor two are oily
Road after the second cross valve confluxes flows to radiator Jing valve port c and fuel tank is flowed back to Jing after coarse filter, and flows through the oil circuit Jing of battery
First two-port valve flows back to fuel tank after flowing to radiator and coarse filter.
8. according to claim 1 two distributed wheel hub driving pure electric automobile temperature regulation system is driven, it is characterised in that
Wheel hub motor is respectively arranged in wheel, can be direct drive structure form, or deceleration drive structure form；Described wheel
Hub motor, can be the motor of permanent-magnet synchronous, switching magnetic-resistance or other forms.
9. according to claim 1 two distributed wheel hub driving pure electric automobile temperature regulation system is driven, it is characterised in that
Affiliated battery can be the different electrokinetic cell such as lithium battery, Ni-MH battery, lead-acid battery.
