Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
Embodiment one：
As shown in figs. 1 and 3, the present embodiment one provide one kind fill electrokinetic cell heating system, including battery pack, the battery pack soon
It is made up of at least one battery cell 2, each battery cell 2 is respectively provided on two sides with calandria 1；Also include temperature acquisition system
System, temperature control system and battery management system, the temperature acquisition system are used for the temperature of Real-time Collection battery, and will collection
The battery temperature for obtaining is sent to battery management system, and battery management system is analyzed to battery temperature, start-up temperature control
System control calandria 1 is heated.
The calandria 1 is arranged at the both sides or inside of each battery cell 2, and the calandria 1 and the temperature
Control system is electrically connected.Described heating film or heating plate is close to the maximum two sides of battery surface product, arranges battery cell 2
When, it is that can ensure that heating film or heating plate are compacted using the thrust between battery cell 2.
In the present embodiment one, the calandria 1 is heating plate or heating film.It is in than relatively low when electrokinetic cell is filled soon
, it is necessary to be heated during temperature, the power supply of heating system is provided in itself by filling electrokinetic cell soon.For some more special cars
, the vehicle-mounted 24V batteries of itself can be with low temperature resistant, then in temperature than in the case of relatively low（Such as less than -20 DEG C）, can be with
First heated to filling electrokinetic cell soon using vehicle-mounted 24V batteries.
In the present embodiment one, the outer surface of the heating plate uses silicon rubber as insulator, the heater of heating plate
It is made of Alloy Foil；The heating film uses high-temperature metal heating film, and insulated part uses polyimides.Described heating film
Or in heating plate, using polyimides as insulating materials, used as heat generating member, thickness is 0.1mm to Alloy Foil to heating film, can be born
Temperature be -150-150 DEG C；Using silicon rubber as insulating materials, Alloy Foil is heating plate as heat generating member, thickness
0.5mm, the temperature that can be born is -50-200 DEG C.Described heating film or the power supply of heating plate come to vehicle-mounted 24V power supplys or profit
