What are the new energy vehicles and power battery?

With the introduction of energy-saving and environment-friendly economy, new energy vehicles are popular in the market, but their safety has always been a controversial topic. In particular, the relationship between power batteries and new energy vehicles has always been controversial. Electric car fire incidents occur from time to time, these incidents are always reminding people, new energy vehicles at this stage there are still many problems, we should always keep a clear head, find out the problem, and constantly improve the safety performance of new energy vehicles.

Battery is the first thing that people think of when a fire occurs in a power car. The grouping technology, usage mode and charging mode of the battery pack in an electric car may all be factors affecting the battery safety. The interdependence between Chinese vehicle manufacturers and power battery manufacturers has a great impact on the safety of power batteries. First is the vehicle of our country enterprise and the power battery enterprise did not form a reliable strategic partner relationship, power battery as the core component of new energy vehicles, should with automobile enterprise jointly develop the relationship between the formation, but the fact is that the vehicle companies tend to put the power battery as spare parts procurement, did not form the interdependent relationship, between each other mutual loyalty is not enough. Second, vehicle enterprises often excessively drive down the price of power batteries, so that power battery enterprises do not have enough profit space, in this case, power battery enterprises often do not have a strong sense of service, will not spend human and material resources to do the development of battery diagnosis system, thus for the power battery buried hidden dangers. In addition, the domestic research and development of power batteries generally lacks deep technical accumulation, many battery manufacturers are only to meet the basic needs of the battery as the goal, and the battery safety is not too much consideration.

In fact, to continue the development of new energy cars, should establish close cooperation relations with power battery, automobile enterprise should be used according to user's requirements, according to the performance of the power battery to develop and design new energy vehicles, rather than just replace the traditional oil tank with power battery; And as power battery enterprise, to understand the importance of the battery for car companies, at design time to put the safety of the battery in the first place, address the environmental adaptability, safety requirements and the reliability of the battery requirements, should pay attention to the battery maintenance system development, improve battery active safety protection ability.

Automobile enterprise and power battery is interdependent relationship, the only real set up a partnership to develop together, therefore, in the future development of automobile enterprise should actively seek cooperation opportunities with power battery enterprise, make progress together.
