Road；Accordingly, the present invention mainly use the battery box 20 of isolation material arrange in pairs or groups metal material heat sink 30 and select merit
The cement resistor 421 that rate is higher is located on this heat sink 30, except making this chargeable Assembled battery be not necessary to via complicated knot
Structure design can have preferably outside radiating effect during overcharge is discharged, and this chargeable collection more can be greatly decreased
Close the conductive area of battery, to reduce the probability causing electrification with producing short circuit, reach to promote the purpose of safety.
Two, the higher suitability.The present invention mainly uses the battery box 20 of isolation material as accommodating each chargeable electricity
Pond 90 is used, therefore, when this chargeable Assembled battery be impacted cause battery box 20 to cave in time, although cause battery case
Rechargeable battery 90 in body 20 is impaired and must change, but when external force releases, this battery box 20 can recover automatically
Becoming original form, so, the battery box 20 of isolation material is then reused, and therefore, the present invention is minimized
This battery box 20 deforms upon and cannot automatically revert to the probability of original form, reaches to promote the purpose of the suitability.
Three, preferably protectiveness.Due to this heat sink 30 except arrange for each this cement resistor 421 and as heat radiation
Outside with, this heat sink 30 has more the heat sink of one and storage tank 21 notch 211 distance apart of this battery box 20
Portion 31, therefore, this heat sink portion 31 covered this overcharge electric discharge device 40 simultaneously, comprised circuit board 41, circuit board body
Positive pole cartridge 411 on 41 and negative pole head 412, overcharge electric discharge the cement resistor 421 of module 42, semiconductor switch 423,
Detecting voltage unit 424, is even positioned at respectively this first and second joint 50,60 of this heat-dissipating space 33, therefore, originally
Heat sink 30 is located on battery box 20 and is positioned at the top of battery box 20 storage tank 21, except as heat transmission by invention
Outside, more covered the assembly being located on battery box 20, to reach to promote the purpose of protectiveness.
