power batteries for electric vehicles importance is self-evident, and therefore the higher the battery pack safety factor, the higher the performance of pure electric vehicles will be safe. So, now what technology can ensure the safety of new battery energy vehicles?
The first
is waterproof and dustproof art battery pack. Now the dust and water technology allows the battery pack to IP67 level, but also to ensure the battery pack immersion in one meter of water for 30 minutes and does not appear water phenomenon. Moreover, the battery pack has leakage protection, if in the course, once the system is monitored to have leakage problem, then the battery pack will power failure to protect the safety of the vehicle occupants.
The second is a battery management system BMS, the system can be real-time monitoring of the voltage and temperature of the battery pack, so as to avoid the occurrence of traction battery voltage or in the case of abnormal temperature.
is the last protective chassis. At present, many battery pack is installed in the chassis position, and the vehicle traveling on the road, there is always the situation encountered rugged missing, then it is possible to make the battery pack has been bump causing damage. Accordingly, in order to protect the battery power, the vehicle chassis will also play a protective role. For example, pressing at a pressure of 120kN, the battery can not be more than 14 percentage deformation. As a result, the power safety of the battery pack on a more secure.
