The value and implementation of battery management systems

Introduction: In short, with the development of the electric vehicle industry, our country may be like Germany's VDA, introducing the specifications of automotive lithium-ion batteries and standardizing battery cells and modules is imperative. Through the series-parallel connection or series-parallel hybrid of battery cells, the uniformity of the battery module size is ensured, and the mechanical, thermal and safety characteristics of the battery body are summarized.

In the context of the government's mandatory parallel processing of fuel consumption and new energy vehicles, a large number of automobile companies have successively launched new energy vehicle development plans and continued to increase their numbers. In order to satisfy a series of plans for plug-in hybrid vehicles (including EREV) and electric vehicles in these areas, car companies must use different combinations to comply with new energy vehicle policy specifications and cater to consumers, adapt to market demand, and demand for cars. The center of demand goals (life journey, hundreds of kilometers of acceleration and charging speed) are for some dynamic equipment and processing, and can cope with the transformation of battery suppliers in the coming May. In the process, let us talk in detail about the value of making a battery management system and how to make a battery management system.(Lithium - Ion Battery Equipment)

In short, with the development of the electric vehicle industry, our country may be like Germany's VDA and introduce cars with lithium-ion battery specifications. The standardization of battery cells and modules is imperative. Through the series-parallel connection or series-parallel hybrid of battery cells, the uniformity of the battery module size is ensured, and the mechanical, thermal and safety characteristics of the 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 on a single module, greatly reducing production costs. This makes the entire battery company's supply based on modules as the smallest unit.

Modular supply has changed the original battery company construction method, the original single battery supply, the automobile company needs to start from a single construction, the entire Bristol-Myers Squibb topology should be selected based on the size of the battery, in the supply of modules, the basic unit becomes A module is assembled.

In this process, the next integrated battery module contains a larger battery pack than a conventional electric vehicle module. In the past, battery modules usually consisted of 12 2-3 kWh battery packs, but now it is starting to switch to a 6-8 kWh battery pack that can accommodate 24 single cells. This will increase battery capacity in the same battery space, helping to increase the range of electric vehicles.
