It need to close pump 3, effective protection pump 3 and cooling circuit, and it is able to achieve the control of simple intelligence.
It should be noted that cooling cycle pressure refers to that the cooling medium retained in battery is formed by pressure, discharge
The cooling medium retained in battery is to discharge the process of cooling cycle pressure.Pump 3 is in the battery cooling circuit for being
The cooling medium provides motivator, flows it in the battery cooling circuit, other are able to achieve the component of the effect
Make substitution pump 3.But it is understood that the cooling medium can be liquid, as an example, cooling medium can be water, then it is right
It answers, battery cooling circuit is water-cooling system, and pump 3 can be water pump, and cooling medium storage unit 4 can be water tank.In some embodiments
In, cooling medium can also be other forms, such as gas.
Reversing mechanism 1 may include a plurality of pipeline, and the opening and closing of a plurality of pipeline are controlled by the control signal,
So that the cooling medium work is in first circuit pattern or work in the second servo loop mode.The cooling medium work
Make in the first circuit pattern for cooling down battery, the battery in the battery unit 2 is in cooling cycle state, cooling medium
Cooling medium in storage unit 4 is transported in battery unit 2, cooling medium flows into again after flowing through battery unit 2 under the action of pumping 3
In cooling medium storage unit 4, cooling medium circulation is constituted.Cooling medium work is in for discharging cooling cycle pressure
When secondary circuit mode, the battery in the battery unit 2 is in cooling cycle stress-released condition, pumps 3 from cooling medium storage unit 4
The cooling medium of middle extraction is directly flow back into cooling medium storage unit 4, battery unit without battery unit 2 by reversing mechanism 1
The cooling medium of retention in 2 battery flows back in cooling medium storage unit, realizes the cooling cycle pressure release of battery.
As an example, the reversing mechanism 1 includes the first pipeline and the second pipeline, wherein one end of the first pipeline
Connect the first port 21 of battery unit 2, the outlet of other end connection pump 3；The outlet of one end connection pump 3 of second pipeline, it is another

In matter storage unit 4, while also being flow back into cooling medium storage unit 4 from the first port of battery unit 21 by third pipeline, it is real
Existing double-direction relief.It should be noted that cooling medium storage unit 4 may include multiple entrances and multiple outlets, the second pipeline, third
The second port 22 of pipeline and battery unit 2 can be connected from different entrance therein respectively, can also be connected with the same entrance.
The battery cooling circuit described in this example is described in detail in two kinds of operating statuses below:
State one, battery cooling circuit cool down battery
In the first circuit pattern for cooling down battery, the battery in battery unit 2 is in cold for the cooling medium work
But recurrent state, the first pipeline are opened, and time connected is constituted between battery unit 2, cooling medium storage unit 4, pump 3 and the first pipeline
Cooling medium in cooling medium storage unit 4 is transported in battery unit 2, after cooling medium flows through battery unit 2, flows back to by road, pump 3
In cooling medium storage unit 4.Under this state, the second pipeline and third pipeline are switched on or off, in order to improve cooling system
Cooling efficiency, the second pipeline and third pipeline can be closed.But it is understood that third pipeline and the second pipe can also be connected
Road, at this point, the cooling medium of 3 extraction of pump separately flows into first port 21, the second pipeline and the third pipeline of battery unit 2, simultaneously
The cooling medium that three paths can be set according to concrete application demand flows into ratio, for example, may be set to 80% cooling medium
The first port 21 of battery unit 2 is flowed into, 10% cooling medium flows into the second pipeline, and 10% cooling medium flows into third pipe
Road.
As an example, reversing mechanism 1 includes four-way reversing valve, as shown in Fig. 2, four-way reversing valve includes first interface

State two, the release of battery cooling cycle pressure
The electricity that the cooling medium works in the second servo loop mode for discharging cooling cycle pressure, in battery unit 2
Pond is in cooling cycle stress-released condition, and the first pipeline is closed, and the second pipeline and third pipeline are opened, pump the 3, second pipeline and
The circuit of a connection is constituted between cooling medium storage unit 4, the cooling medium of 3 extraction of pump by flowing after the second pipeline again
It returns in cooling medium storage unit 4.Returning for another connection is constituted between battery unit 2, third pipeline and cooling medium storage unit 4
Road, battery unit 2 are located at a high position relative to cooling medium storage unit 4, and there are pressure for the cooling medium in battery unit 2, therefore, this time
After road is connected, the cooling medium in battery unit 2 will automatically flow into cooling medium storage unit 4 from the two lines road that battery is connect,
Cooling medium i.e. in the battery of battery unit 2 flows into cooling medium storage unit 4 by second port 22, while also passing through battery unit
2 first port 21 flows through third pipeline and flows into cooling medium storage unit 4, to discharge 2 cooling cycle pressure of battery unit.
Work shape when still further being discharged to battery cooling cycle pressure so that reversing mechanism 1 includes four-way reversing valve as an example
State is illustrated, example as shown in Figure 3, under the working condition, in four-way reversing valve, between first interface 11 and second interface 12
Disconnect, connected between second interface 12 and the 4th interface 14, the cooling medium of 3 extraction of pump passes through second interface 12 and the 4th
It after the second pipeline between interface 14, is flowed back in cooling medium storage unit 4 again, the cooling medium flow direction such as A arrow in Fig. 3 refers to
To shown.It is connected between first interface 11 and third interface 13, the cooling medium in battery unit 2 with first interface 11 by being connected
One end route outflow after, after flowing through the third pipeline between first interface 11 and third interface 13, flow back to cooling medium and deposit
In storage portion 4, cooling medium flow direction is as shown in the B arrow direction in Fig. 3.Meanwhile the direct battery unit of cooling medium in battery unit 2
The route of 2 other ends flows back in cooling medium storage unit 4, and cooling medium flow direction is as shown in the C arrow direction in Fig. 3, thus complete
At the release of battery cooling cycle pressure.In addition, cooling medium storage unit 4 can also set one for draining outlet, and one can be set
Control switch 41 controls on-off, so that the draining of cooling medium storage unit 4 is controlled, as shown in figure 4, control switch 41 can be electromagnetism
Valve, structure is simple, easy to control, and at low cost.
In electric charging station, a battery cooling circuit usually connects multiple batteries 2, for controlling the temperature of multiple batteries
Therefore degree can access a reversing mechanism 1, the whole cooling for controlling multiple batteries that water-cooling system is connected in total line
Circulating pressure release.Specifically: the reversing mechanism 1 connects multiple battery units 2, multiple series connection of battery unit 2 and/or parallel connection, and
As a whole, by the control of the same reversing mechanism 1, by taking multiple battery units 2 are parallel with one another as an example, the battery is cooled back
Road is as shown in Figure 4.It should be noted that making the multiple groups by the opening and closing of a plurality of pipeline in control reversing mechanism 1
Battery unit 2 is switched on or switched off with pump 3, to control the cooling cycle pressure release of the multiple groups battery unit 2 simultaneously.
As another example, the battery cooling circuit includes multiple reversing mechanisms 1, and each reversing mechanism difference 1 connects
