Shortcoming:
First, water pump is in operation the mode having been used up constant speed for cooling water circulation offer circulation power, this state
Under power motor be under severe operating mode be possible, but, be in rated speed or low speed fortune at power motor
During row, the now temperature rise of power motor is the most little, and the speed of service of water pump is the highest, thus consumes substantial amounts of energy, and
The power source of electric automobile is power accumulator, and big consumption of water pump causes the flying power of power accumulator to decline, thus shadow
Ring the vehicle performance to electric automobile；
Secondly, in traditional water-cooling pattern, after power motor power-off, water pump quits work immediately, and that can cause in water route is cold
But Liquid backwash, causes circulating water line to bear relatively big bounce pressure, thus proposes circulating water line higher high temperature resistant
With resistance to pressure request so that the production cost of electric automobile increases；
Again, after power motor power-off quits work, water pump is the most out of service, and now the temperature of power motor is still
The highest, the constant temperature of power motor can be caused to rise, time serious, even damage motor.
It is, therefore, desirable to provide a kind of new electric automobile water-cooling control system, it is possible to effectively reduce in water pump operation and disappeared
The electric energy of consumption, improves the flying power of electrokinetic cell, and can effectively prevent cooling liquid from recoiling, effectively protect circulating water pipe
Road system, and can continue power motor is cooled down after power motor quits work, prevent power motor from damaging.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of electric automobile water-cooling control system, it is possible to effectively subtract

Effectively protection circulating water line system, and can continue power motor is cooled down after power motor quits work, anti-
Stopping power motor damage.
A kind of electric automobile water-cooling control system that this utility model provides, including for the power motor to electric automobile
The recirculated water cooling unit that carries out cooling down with power motor controller, for driving cooling water circulation water pump, for detecting power
Motor and the temperature detecting unit of power motor controller temperature and the controller being connected with described temperature detecting unit, described
It is out of service that controller output control command controls water pump time delay after water pump stops with different rotating speeds work and power motor.
Further, described cooling unit includes circulating water line and is arranged at the radiator of circulating water line.
Further, described cooling unit also include for accelerate radiator surrounding air flowing blower fan, described blower fan by
Controller controls.
Further, described temperature detecting unit includes the first temperature sensor for detecting power motor temperature and use
In the second temperature sensor of detection power motor controller temperature, described first temperature sensor and the second temperature sensor are equal
It is connected with controller.
Further, described controller is entire car controller.
The beneficial effects of the utility model: electric automobile water-cooling control system of the present utility model, it is possible to effectively reduce water
The electric energy consumed in pump operation, improves the flying power of electrokinetic cell, and can effectively prevent cooling liquid from recoiling, effectively
Protection circulating water line system, and can continue power motor is cooled down after power motor quits work, anti-stop
Force motor damages.
Accompanying drawing explanation
With embodiment, this utility model is further described below in conjunction with the accompanying drawings:
Fig. 1 is cooling schematic diagram of the present utility model.
Fig. 2 is theory diagram of the present utility model.
Detailed description of the invention
Fig. 1 is cooling schematic diagram of the present utility model, and Fig. 2 is theory diagram of the present utility model, and the arrow in Fig. 1 represents
Loop direction, a kind of electric automobile water-cooling control system that this utility model provides as shown in the figure, including for electric automobile
Power motor and power motor controller carry out cooling down recirculated water cooling unit, for driving cooling water circulation water pump, use
In detection power motor and the temperature detecting unit of power motor controller temperature and it is connected with described temperature detecting unit
Controller, described controller output control command controls water pump time delay after water pump stops with different rotating speeds work and power motor
Out of service, pass through said structure, it is possible to effectively reduce the electric energy consumed in water pump operation, improve the continuation of the journey energy of electrokinetic cell
Power, and can effectively prevent cooling liquid from recoiling, effectively protection circulating water line system, and can stop at power motor
Continue after work power motor is cooled down, prevent power motor from damaging.
In the present embodiment, described cooling unit includes circulating water line and is arranged at the radiator of circulating water line, institute
Stating cooling unit and also include the blower fan for accelerating the flowing of radiator surrounding air, described blower fan is by controller control, by this
Plant structure, it is possible to effectively strengthen cooling effect, it is ensured that the performance of electric motor car.
In the present embodiment, described temperature detecting unit include for the first temperature sensor detecting power motor temperature with
And for detecting the second temperature sensor of power motor controller temperature, described first temperature sensor and the second temperature sensing
