The battery pack assembly method:
1, by the holddown groove on the crossbeam bottom heating panel is fixed on the support frame;
2, the ladder double-screw bolt is screwed in the screwed hole on the crossbeam, the first order step by the ladder double-screw bolt is fixed on bottom thermal-arrest plate on the heating panel of bottom, and fastening with first order hold-down nut.
3, behind bottom thermal-arrest plate upper surface coating heat conductive silica gel cell the alignd projection of thermal-arrest plate is put into.
4, put into upper strata thermal-arrest plate and second level hold-down nut on the ladder double-screw bolt is installed at the cell upper surface coated with thermally conductive silica gel of putting into and its groove that aligns.
5, repeat 3,4.
6, in the connecting through hole of heat-transfer device insertion equivalent layer thermal-arrest plate and in the corresponding bottom thermal-arrest plate connecting through hole.
7, corresponding two the cell two ends of layer and interlayer are connected by 2 braces respectively, brace can preferably be fixed on the edge pole by being bolted on any one pole in cell a plurality of poles side by side.
The invention has the advantages that:
1. every layer of battery all has corresponding with it thermal-arrest plate in the battery pack, the heat of deriving from the thermal-arrest plate of upper strata focuses in the thermal-arrest plate of bottom, the heating panel of bottom thermal-arrest plate and bottom is combined closely, the transmission of collection that the heat that gives out of every battery upper and lower surface can both be by the thermal-arrest plate and heat-transfer device and effectively distribute rapidly like this by bottom half, thus guarantee that battery pack has excellent heat dispersion.
2. every layer of thermal-arrest plate all has the projection that matches with the battery surface groove, when so not only having guaranteed that itself and battery have enough contacts area to transmit the heat that battery sends but also having guaranteed that battery is installed the location accurately and strength of fixation.
3. the thermal-arrest plate is fixed by the ladder double-screw bolt, and every layer of battery can accurately be located like this, guarantees the weight that does not have erection stress after battery is installed and alleviated fixture.
4. whole battery group compact conformation, have in light weight, the advantage that volume is little.
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
