In short, with the development of the electric vehicle industry, China may also be the same as Germany's VDA, the introduction of automotive lithium-ion battery specifications, and the standardization of battery cells and modules is imperative. By series parallel or series parallel mixing of battery cells, the uniformity of battery module size is ensured, and the mechanical, thermal and safety characteristics of battery body are summarized.
Under the big scenario of the government forcing the parallel processing of fuel consumption and new energy vehicle points, a large number of automobile companies have launched new energy vehicle development plans and continue to increase. In order to be satisfied with a series of plans for plug-in hybrid electric vehicles (including EREV) and electric vehicles in these fields, car companies have to use different combinations to meet the policy specifications of new energy vehicles and cater to consumers, adapt to market demand, the center of the demand for cars (life journey, hundreds of kilometers acceleration and charging speed) on some dynamic equipment and processing, and can To cope with the transformation of battery suppliers in the coming May. In this process, let's talk about the value of making a battery management system in detail, and how to make a battery management system.
The top of the modular power supply
In short, with the development of the electric vehicle industry, China may also be like the German VDA, the introduction of lithium-ion battery specifications of cars, battery monomer and module standardization is imperative. By series parallel or series parallel mixing of battery cells, the uniformity of battery module size is ensured, and the mechanical, thermal and safety characteristics of battery body are summarized. Without changing the installation method, different battery capacities are supplied according to different ranges and power requirements to meet different requirements. This modular application can complete large-scale automated production in a single module end, greatly reducing production costs, which makes the supply of the entire battery company is based on modules as the smallest unit.
The modular supply changes the original battery company construction method, the original single battery supply, the automotive company needs to build from a single start, the entire Bristol-Myers Squibb topology should be based on the size of the battery to measure the choice, in the module supply, the basic unit becomes a module assembly.
In the process, the next integrated battery module contains a larger battery pack than a conventional electric vehicle module. In the past, the battery module usually consisted of 12 2-3 KWH battery packs, but now it is starting to switch to a 6-08 KWH battery pack that can hold 24 single cells. This will increase battery capacity in the same battery space, conducive to the addition of electric vehicle mileage.
