Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
Structure of the present invention as shown in Figure 1 to Figure 3, be a kind of omniseal battery case, specifically a kind of LiFePO4 omniseal battery case, comprises casing 4, upper cover 1, battery pack 10 and BMS.Described BMS is battery management system.Described BMS and battery pack also comprise control port, radiator portion.The present invention is the core component of electric automobile---the structural manufacturing process technology of battery, it directly has influence on the usage safety performance of pure electric automobile.Omniseal battery case of the present invention is to realize the round-the-clock driving safety of pure electric automobile.
Power battery of pure electric automobile group output voltage is at about 300V, and the Battery case of electrokinetic cell is as the necessary waterproof of power source, and prevent from causing short circuit into water, the designing requirement of its degree of protection of Battery case must reach IP67.
For leaning on natural air cooled battery case, battery case must be sealing, can install unidirectional valve additional, not only can provide cooling duct, also can play explosion-proof in upper cover body;
For the battery case by air blast cooling, all can not communicate with air except necessary ventilation ventilation hole.
Requirement in omniseal battery case, the main flow field problem considering cooling blast, and the danger that the easy watered and wetting of the power source overcoming pure electric automobile is short-circuited.
The version of the present invention to the casing of battery case and upper cover is carried out office of reasonable portion and reinforcing, is added sealing strip and sealing gasket.Close process is carried out to each port of battery case casing.It is made to reach the IP67 grade standard of shell protection.
