The BMS battery management systems for being preset with battery thermal management strategy gather the temperature of each battery module 8 in real time, in real time
After collecting temperature data, the judgement of Current Temperatures situation is made according to default battery thermal management strategy.
When the temperature data of collection is higher than the value that BMS battery management systems are set according to thermal management policy, BMS cell tubes
Reason system sends cooling signal to vehicle-mounted control component, and vehicle-mounted control component receives the cooling that BMS battery management systems are sent
After signal, the sucking pump of temperature-regulating module is opened in control, and temperature adjusting liquid is passed through liquid injecting pipeline 5 after importing and exporting connector, then is reached every
Block liquid cooling plate 1, using the heat exchange of liquid cooling plate 1 and battery module 8, and in liquid cooling plate 1 temperature adjusting liquid flowing, battery can be taken away
The heat of battery cell 1 is simultaneously transmitted on liquid cooling plate 1 by the heat of monomer 1, to take away the heat of battery cell 1, so as to ensure
The heat of whole battery module shifts and ensures whole battery module and be in preferable operating temperature in time.

The New-energy electric vehicle getting up early environment temperature that cold district uses may be less than minus 20 degrees, or New-energy electric vehicle
When just starting to charge up, temperature may also be less than minus 20 degrees.At this moment the temperature number that BMS battery management systems collect in real time
During according to that can be less than value that BMS battery management systems are set according to thermal management policy, BMS battery management systems can be to vehicle-mounted control group
Part sends heat temperature raising signal, vehicle-mounted after vehicle-mounted control component receives the heat temperature raising signal that BMS battery management systems are sent
The heater work that liquid reserve tank corresponds to configuration is opened in control assembly control, to be heated to temperature adjusting liquid, treats the temperature adjustment of liquid reserve tank
When the temperature of liquid reaches required temperature, sucking pump is opened, temperature adjusting liquid is passed through liquid injecting pipeline after importing and exporting connector, then reaches every
Block liquid cooling plate 1, using the heat exchange of liquid cooling plate 1 and battery module, and in liquid cooling plate 1 temperature adjusting liquid flowing, to battery module 8
Heated, so as to ensure the temperature rise of whole battery module and ensure whole battery module and be in preferably work temperature
Degree.
In above process, due to from the temperature adjusting liquid after the heating of heated device that liquid reserve tank exports along liquid injecting pipeline 5
The process of circulation in can be there are the loss of heat, difference can be caused by losing after the temperature adjusting liquid after heat injects different liquid cooling plate 1
Liquid cooling plate 1 is inconsistent for the temperature rise effect of respective battery modules 8, therefore after sucking pump is opened, vehicle-mounted control component can intelligence
The ptc heater that the 1 corresponding liquid injecting pipeline of liquid cooling plate of ground control different masses is set starts heating, for adjusting liquid injecting pipeline note
Enter the temperature of the temperature adjusting liquid in different masses liquid cooling plate 1, improve the temperature adjustment to the battery module 8 of diverse location in lithium battery group
Uniformity.
Specifically, during the control of above-mentioned vehicle-mounted control component control ptc heater, when BMS battery management systems
Discrepancy delta of the mean temperature of the whole unit of the battery module 8 collected with the mean temperature of the battery core of whole battery module
When V reaches 3 DEG C and the above, vehicle-mounted control component will control the liquid cooling plate 1 for opening the correspondence of the utility model battery module 8
Ptc heater 2 start heating；When the battery module 8 that BMS battery management systems collect whole unit mean temperature with
When the discrepancy delta V of the mean temperature of the battery core of whole battery module is less than or equal to 1 DEG C, vehicle-mounted control component will control pass
The ptc heater for closing the liquid cooling plate 1 of the correspondence of the utility model battery module 8 stops heating.With specific reference to as shown in the table：
| Sequence number | Ptc heater | Decision condition |
| 1 | Open | ΔV≥3°C |
| 2 | Close | ΔV≤1°C |
Δ V=V1-V2 in upper table；
V1 is the mean temperature after the cumulative total value of the temperature of the battery core of battery module divided by total temperature spot number；
Total temperature spot number in the cumulative total value divided by unit of the battery core temperature for the battery module 8 that V2 heats for needs
Mean temperature afterwards.
