Shown in Fig. 1-2,10-11, front panel 21 and back panel 22 are arranged on the front and back of some battery modules 10 respectively, front panel 21 is provided with front air inlet 21a, front-outlet mouth 21b and front fixing hole 21c, the outlet in front-outlet mouth 21b and first air channel, screw screws in front panel 21 in stud 29 through front fixing hole 21c.Back panel 22 is provided with back side air inlet 22a, back side air outlet 22b and back side fixing hole 22c, the outlet in air outlet 22b and second air channel, the back side, screw screws in stud 29 through back side fixing hole 22c and back panel 22 is fixed.
Forced ventilation heat radiation and battery pack heater are two groups, two groups of forced ventilation heat radiations and battery pack heater are arranged on the inner side of front panel 21 and back panel 22 respectively, give the positive pole ear of the monomer module of internal battery pack and front and negative lug and back side heating respectively simultaneously or dispel the heat.Forced ventilation heat radiation and battery pack heater comprise wind scooper 24, blower fan 25 and heater 26, the import of wind scooper 24 is communicated with the back side air inlet 22a of the front air inlet 21a of front panel 21 or back panel 22, the outlet of wind scooper 24 is communicated with the air inlet of blower fan 25, the inlet communication of the air outlet of blower fan 25 and the heat tunnel of heater 26, the outlet of heat tunnel is communicated with the back side air outlet 22b of the front-outlet mouth 21b of front panel 21 or back panel 22.The front air inlet 21a of the front panel 21 and back side air inlet 22a of back panel 22 and wind scooper 24 and the gap between wind scooper 24 and heater 26 seal by sealing ring, prevent gas leakage and dust from entering internal battery pack.Blower fan 25 in the present embodiment is turbofan.As can be seen here, this power battery pack has two covers, and the flexible packing lithium ion battery face that two cover heat radiation/heating systems are responsible for cell positive pole ear or negative lug and correspondence respectively carries out dispelling the heat or heating, and therefore heat radiation/heating effect is good.
Total cathode metal plate 27 and total negative metal plate 28 expose from the top of front panel 21 and back panel 22 respectively, more preferably, positive pole drainage metal bar 15 laser welding of total cathode metal plate 27 and total negative metal plate 28 and battery module 10, laser welding can make the charge and discharge multiplying power of battery accomplish the limit of cell, the energy loss avoiding the resistance because of mechanical connection to cause, avoids the thermal runaway caused because internal resistance is too high.
Top panel 23 is fixed on the top of some battery modules 10, shields.
The operation principle of power battery pack 20 of the present invention is as follows:
When power battery pack 20 internal temperature raises, control system controls blower fan 25 rotation makes cold air be entered the heat tunnel of heater 26 from wind scooper 24 by the front air inlet 21a of the front panel 21 and back side air inlet 22a of back panel 22, because be the internal heat that sheds, the heater strip of heater 26 does not work, cold air enters the air channel that some battery modules 10 are formed, heat on fin 16c in air channel is taken away, thus reduce the positive pole ear of flexible packing lithium ion battery 12 and the temperature on negative lug and flexible packing lithium ion battery 12 surface, hot-air after heat exchange flows out from the front-outlet mouth 21b of the front panel 21 and back side air outlet 22b of back panel 22.
Otherwise, when power battery pack 20 internal temperature is too low, control system opens the heater strip of blower fan 25 and heater 26, blower fan 25 is rotated and makes cold air be entered the heat tunnel of heater 26 from wind scooper 24 by the front air inlet 21a of the front panel 21 and back side air inlet 22a of back panel 22, the heater strip of heater 26 is by after cold air heating, enter in the air channel of some battery modules 10 formation, fin 16c in air channel is heated, thus by the positive pole ear of flexible packing lithium ion battery 12 and negative lug and flexible packing lithium ion battery 12 surface heating, cold air after heat exchange flows out from the front-outlet mouth 21b of the front panel 21 and back side air outlet 22b of back panel 22.
To sum up, power battery pack of the present invention has following beneficial effect:
1, power battery pack of the present invention has heat-exchange system, and the heat that flexible packing lithium ion battery 12 charge and discharge process produces is transmitted to outside batteries by heat-exchange system, uses and forces the method for air flowing to be dispersed into module-external; Simultaneously when temperature is lower need heating time, use outside heat by heat-exchange system to heating of battery, make cell be in best working temperature, thus effectively improve cold district motor vehicle cannot the problem of charging and discharging.Thus solve current electric automobile, the bad or too low problem cannot charged, discharge caused of temperature of electrokinetic cell heat radiation that electric bus, electric bus use.
2, power battery pack of the present invention, the positive pole ear of flexible packing lithium ion battery 12 or negative lug are not generated heat or heat is very fast is transmitted to outside batteries by heat-exchange system, use and force the method for air flowing to be dispersed into module-external, go for the battery of high magnification charge and discharge.
3, power battery pack of the present invention, after multiple group of battery modules is combined, the re-entrant portion of the fin installation position of heat-exchange system can form air channel; Weld the drainage metal plate of battery pack after battery module combination, use metal binding belt to process in groups, entrucking can be directly used in after adding auxiliary accessories and use, the outer container of battery pack need not be increased again.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.
