It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, specific embodiment to a kind of battery temperature control device proposed according to the present invention and method and
Its effect, detailed description is as follows.
The embodiment of the present invention provides a kind of temperature control equipment of battery pack, as shown in Figure 1, comprising: diversity water module 1,
Multiple flow-control modules 2 and multiple pipelines 3,；Wherein, one end of each pipeline 3 is connected to the diversity water module 1,
The other end of each pipeline 3 is for connecting corresponding battery pack；The flow-control module 2 is set on the pipeline 3,
For controlling the flow for flowing through the coolant liquid for the battery pack that each pipeline 3 is connected.
As an example, pipeline 3 refers to the pipeline that working fluid is transmitted in hydraulic system.Diversity water module 1 includes total
One end of water supply pipe 11 and total water return pipeline 12, the water supply pipe 31 of each pipeline 3 in multiple pipelines 3 individually connects
To total water supply pipe 11 of diversity water module 1, one end difference of the water return pipeline 32 of each pipeline 3 in same multiple pipelines 3
It is connected to total water return pipeline 12 of diversity water module 1, the water supply pipe 31 of each pipeline 3 is connected with the other end of water return pipeline 32
To battery pack, while it being provided with flow-control module 2 in each pipeline 3 of multiple pipelines 3, it is achieved that each pipeline 3
Independent operating, and then individual flow control can be carried out for the battery pack for the different model for accessing each pipeline 3.
Further, user can input corresponding flow control for different battery sizes by control panel and join
Number, and then flow control ginseng set by user is obtained by the parameter acquiring unit (not shown) in flow-control module 2
Number, so that the flow controlling unit 21 in flow-control module 2 can control according to flow control parameter and flow through battery pack
The flow of coolant liquid.
Embodiment one,
Above-mentioned flow control parameter set by user can be the setting flow (battery pack connected according to the pipeline 3
Model setting the coolant liquid suitable for the battery pack flow), and then obtained singly by the parameter in flow-control module 2
Member obtains the setting flow, so that the flow controlling unit 21 in flow-control module 2 can be according to the setting flow control
Flow through the flow of the coolant liquid of battery pack.
In a specific embodiment, as shown in Figure 1, user carries out flow set, specifically, Yong Huke to 1# battery pack
In the range of flow of formulation, to choose flow corresponding to 1# battery pack by software operation interface, chooses and completes in user,
And after parameter acquiring unit gets flow selected by user, 21 adjust automatically of flow controlling unit will flow through 1# battery
The flow of the coolant liquid of packet is fixed on flow selected by user, and the coolant liquid for flowing through 1# battery pack starts the cycle over.
Embodiment two,
The flow control parameter that above-mentioned user is set by control panel can be preset temperature range (i.e. according to battery pack
Model setting water supply pipe 31 in coolant liquid temperature and coolant liquid in water return pipeline 32 temperature difference range), tool
Body, first flow controlling unit 21 flow through the flow of the coolant liquid of battery pack according to initial flow control, and (initial flow is
Obtained according to temperature difference discharge relation empirical value), and then the first temperature by being arranged in the water supply pipe 31 in each pipeline 3
Sensor 22 detects the first Current Temperatures of coolant liquid in the water supply pipe 31, passes through the return pipe being arranged in each pipeline 3

It starts the cycle over.At this point, detecting the first Current Temperatures of coolant liquid in water supply pipe 31 by the first temperature sensor 22, pass through
Second temperature sensor 23 detects the second Current Temperatures of coolant liquid in water return pipeline 32, and then by calculating the second current temperature
Difference between degree and the first Current Temperatures, obtains Current Temperatures difference, if the current temperature gap is in preset temperature model at this time
It is that the circulation of coolant liquid is then still carried out according to the first preset flow in enclosing；If the current temperature gap is greater than preset temperature range
The upper limit when, then flow controlling unit 21 persistently increases the flow value for flowing through the coolant liquid of battery pack according to system algorithm, until
Above-mentioned Current Temperatures difference is in preset temperature range, then control is recycled according to flow value at this time；If Current Temperatures
When difference is less than the lower limit of preset temperature range, then flow controlling unit 21 flows through the cold of 2# battery pack according to system algorithm reduction
But the flow of liquid is then controlled and is carried out according to flow value at this time until above-mentioned Current Temperatures difference is in preset temperature range
Circulation.

And guarantee that the flow for the coolant liquid for flowing through each battery pack can satisfy the demand of battery pack heat dissipation, and the variable frequency pump being capable of basis
The flow demand adjust automatically running frequency of current coolant liquid is achieved the purpose of energy saving with this.
As an example, the temperature control equipment of battery pack further includes fixed frequency pump and bypass circulation, wherein the fixed frequency pumps
Flowing for the coolant liquid in diversity water module 1 provides kinetic energy, and the bypass circulation is cooling in the diversity water module 1 for adjusting
The flow of liquid.Specifically, it because fixed frequency pump can not change running frequency, therefore is needed in flow of the temperature control equipment to coolant liquid
When asking smaller, in order to enable flow controlling unit 21 can preferably control the flow for flowing through the coolant liquid of battery pack, it can pass through
Bypass circulation is adjusted the flow of coolant liquid in diversity water module 1.
