The technical status of thermal management in new energy vehicles is actually no less than the “three power”, because the battery, motor, electric control need thermal management system to ensure and optimize the performance of the system, the major Oems are also constantly researching and upgrading the thermal management system, the purpose of new energy vehicle thermal management system technology iteration is to achieve the internal matching of the heat and cold demand of each loop, and the optimal energy consumption. Reduce battery energy consumption to achieve cooling and heating functions.
At present, national departments have successively issued policies to prevent and control the spontaneous combustion and explosion of batteries in extreme circumstances. The reason why spontaneous combustion accidents occur is not only the problem of leakage or short circuit on the circuit, but also the thermal management strategy and thermal management circuit design of the on-board controller directly affect the safety of electric vehicles.
Although the country does not have guidance requirements for specific thermal management technical routes at this stage, it does not have clear and targeted standards for thermal management testing like automotive interior and exterior decoration or automotive electronics. However, compared with fuel vehicles, the working conditions and working purposes of the thermal management system of new energy vehicles are different, and they also shoulder more important functions, performance, energy saving, and safety “responsibilities”.
The performance requirements of Oems for thermal management are also constantly upgrading, and they need to have more efficient and more comprehensive thermal management systems. Therefore, in the new era of tens of millions of new energy vehicles in China, the Oems have gradually changed from the earlier requirements of only testing components in the thermal management system to the comprehensive concern about components, sub-circuits, and overall system performance, and the ensuing test demand is also increasing.
On the other hand, in the past, the Oems or suppliers established their own laboratories to meet their requirements for thermal management system performance or environmental reliability testing, but with the upgrade of demand, oems or suppliers need third-party testing institutions to complete the test, so in recent years, the test demand for thermal management has been rising.
To sum up, the thermal management system capability will become an important part of the technical capability competition pattern of the industry in the future, and its test demand and technical position occupy a place in the field of new energy vehicles.
