By draining valve, water is expelled directly out.
Vavuum pump 12 is vane-type vacuum pump, can directly utilize the brake boosting vacuum pump of car load,
When drainage arrangement 6 starts, vavuum pump 12 works and the water in discharge pipe line 7 is sucked surge tank
In 11.
The draining further illustrating the present invention below by way of two detailed description of the invention controls plan
Slightly:
Embodiment 1
Rated voltage 320V of the electrokinetic cell system being equipped on pure electric automobile, capacity
80Ah, electrokinetic cell casing 1 uses direct wind-cooling heat dissipating mode, and bottom uses pyramidal structure to set
Meter, the environment temperature in the normal driving process of car load is-10 DEG C, and air-cooled gas temperature is 20 DEG C,
The box body wall of air-cooled gas contact Battery case 1 produces condensed water, and via taper tank floor
Enter in drainage arrangement 6；After car load stagnation of movement, water sensor 11 detects in discharge pipe line 7
The water yield, not up to discharge level predetermined value (0.5cm), car load normally lower electricity；After 20d, the water yield
Sensor 9 detects that the water level in discharge pipe line 7 has reached 0.5cm, full-vehicle control 1# electromagnetism
Valve 8 cuts out, 2# magnetic valve 10 open, afterwards control brake boosting vacuum pump work, draining
Water in pipeline 7 is drawn in surge tank 11, when water sensor 9 detects discharge pipe line 7
In water level less than 0.1cm time, full-vehicle control brake boosting vacuum pump quits work, same to time control
1# magnetic valve 8 processed is opened, 2# magnetic valve 10 cuts out, and car load can be normally lower electric.Car load is normal
After lower electricity, being discharged by the water the most at last of the draining valve on surge tank 11, draining terminates.
Embodiment 2
Electrokinetic cell system rated voltage 320V being equipped on pure electric automobile, capacity 80Ah,
The bottom of electrokinetic cell casing 1 uses taper structure design, runs in the normal driving process of car load
The serious ponding of rainstorm weather and road surface, causes having water accidentally to enter the interior of electrokinetic cell casing 1
Portion, and enter in drainage arrangement 6 via taper tank floor；After car load stagnation of movement, the water yield senses
Device 9 detects that the water level in discharge pipe line exceedes preset value (0.5cm), full-vehicle control 1#
Magnetic valve 8 cuts out, 2# magnetic valve 10 is opened, and controls brake boosting vacuum pump 12 afterwards and works,
Water in discharge pipe line 7 is drawn in surge tank 11, until water sensor 9 detects draining
When water level in pipeline is less than 0.1cm, full-vehicle control brake boosting vacuum pump 12 quits work,
1# magnetic valve 8 is opened, 2# magnetic valve 10 cuts out in control simultaneously, and car load can be normally lower electric.Whole
Under car after electricity, finally being discharged by water by the draining valve on surge tank 11, draining terminates.
It can be seen that the present invention solves the steam brought due to wind-cooling heat dissipating at battery simultaneously
The timely discharge of the water accidentally entering inside battery with other modes is condensed, it is ensured that car load in bag
Driving safety, consolidated the reliability of direct air-cooled heat management mode.
As it has been described above, embodiments of the invention are explained, it is clear that if real
In matter without departing from the inventive point of the present invention and effect, be aobvious to one skilled in the art
And the deformation being clear to, within being also all contained in protection scope of the present invention.
