Embodiment Construction
[0057] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the invention, not to limit the invention.
[0058]The power battery management system proposed in the present invention is based on the module series battery pack platform, through the redevelopment of the functions of the power battery management system BMS, basic requirements are put forward for the matching of other types of modules, and new other types of modules are required. A matching method is proposed for the characteristic performance parameters of type module cells, and finally realize that after replacing individual module cells in the old battery pack with new and other types of module cells, the performance of the whole package, such as SOC and...

The invention relates to the technical field of electric vehicles, and more specifically, to a power battery management system and a matching method. The present invention provides a power battery management system, which includes a characteristic parameter module, the characteristic parameter module matches and corresponds to the module cell; when the module cell is replaced, the characteristic parameter module selects the corresponding characteristic parameter, and the new The characteristic electrical performance parameters of the module cells are adjusted to match the needs of the old battery pack. The matching method of the power battery management system provided by the present invention realizes the replacement of individual module cells in the old battery pack with new and other types of module cells through the adaptive and innovative function development of the power battery management system , does not need to increase the cost and time of matching calibration test, does not affect the performance level of the battery pack, and reduces the after-sales cost.
Description
technical field [0001] The invention relates to the technical field of electric vehicles, and more specifically, to a power battery management system and a matching method. Background technique [0002] With the rapid development of the new energy automobile industry, the replacement speed of electric vehicle models is relatively fast. Although most OEMs have developed their own battery pack platform products, the module level still needs to be constantly updated, including the following two aspects: [0003] On the one hand, it comes from the passive replacement demand brought about by the continuous upgrading of battery technology, and on the other hand, it comes from the active replacement demand brought about by the secondary supply development of the battery module supplier of the OEM. [0004] However, with the update of modules, there will be models equipped with battery packs of different types of modules from a certain OEM in the market. After these models enter th...
