Heated filament, blower fan 25 rotates front air inlet 21a and the back side air inlet of back panel 22 making cold air pass through front panel 21
22a enters the passage of heat that adds of heater 26 from wind scooper 24, after cold air is heated by the heater strip of heater 26, if entering
In the air channel that aneroid battery module 10 is formed, the fin 16c in air channel is heated, thus by the positive pole of flexible packing lithium ion battery 12
Lug and negative lug and flexible packing lithium ion battery 12 surface heat, and the cold air after heat exchange goes out from the front of front panel 21
The back side air outlet 22b of air port 21b and back panel 22 flows out.
To sum up, power battery pack of the present utility model has the advantages that
1, power battery pack of the present utility model has heat-exchange system, and flexible packing lithium ion battery 12 charge and discharge process produces
Raw heat is transmitted to outside batteries by heat-exchange system, uses the method forcing air flowing to be dispersed into module-external；With
Time when temperature than relatively low need heating time, use outside heat by heat-exchange system to battery heat, make cell be in
Optimal operating temperature, thus be effectively improved cold district electric vehicle cannot the problem of charging and discharging.Thus solve at present
The heat radiation of electrokinetic cell that electric automobile, electric bus, electric bus are used is bad or temperature too low cause cannot fill
Electricity, the problem of electric discharge.
2, power battery pack of the present utility model, positive pole ear or the negative lug of flexible packing lithium ion battery 12 are not generated heat
Or heat quickly be transmitted to outside batteries by heat-exchange system, use the method forcing air flowing to be dispersed into outside module
Portion, goes for the battery of high magnification charge and discharge.
