Examples
At the present stage, based on the consideration of technology, process maturity and processing cost, a stamping type liquid cooling plate scheme based on a power battery pack CTP structure is selected for domestic and overseas mainstream new energy automobiles, and the CTP integration scheme has the advantage of high grouping efficiency and specifically comprises the following steps: (1) The cold plate is used as a bottom plate of the battery pack, so that the Z-direction space is effectively reduced; (2) In the aspect of heat management efficiency, the contact area of the flow channel is large, the temperature difference between the upper part and the lower part inside the single battery can be effectively reduced, and the battery is well protected during rapid charging and discharging and low-temperature preheating. In addition, the integrated outside at power battery package of punching press formula liquid cold plate as an solitary part, save occupation space, reduce cost, but also can accomplish dry wet-separating, its coolant liquid if reveal, can not form the short circuit with high-pressure spare parts contact such as module, busbar, can not lead to the battery package incident such as short circuit on fire, from the long run, very be favorable to new energy automobile's development requirement.
The inventor finds that the CTP battery pack has high weight grouping efficiency and relatively poor whole pack rigidity in the design process, and the currently adopted method is as follows: the bottom insulating film of electric core is windowed, is coated with structure heat-conducting glue, then directly pastes it to lower box. When the battery is in a complex vibration impact working condition, one part of the inertia force of the battery core is transmitted to the lower box body cross beam through the bottom structure heat-conducting glue and then transmitted to the whole package hanging point, and the other part of the inertia force is transmitted to the whole package hanging point through the end plate, so that the rigidity of the CTP battery package can be improved.
The disadvantages of this method are: the structure is glued to lead the bonding power of heat and is very strong, hardly dismantles electric core, even adopt specialized tool, also produces risks such as weeping, thermal runaway very easily, if appear an electric core pressure differential big, the low scheduling problem of capacity, can't dismantle and change new electric core, whole battery package just will scrap the processing, and its production and after-sale cost of maintenance are very high, are unfavorable for new energy automobile's development, are unfavorable for coming the recycle of battery package.
