Huawei Digital Energy has obtained a patent for a battery module, battery pack, and energy storage system, aimed at extending the lifespan of batteries. According to information from the National Intellectual Property Administration, the patent, titled “A Battery Module, Battery Pack, and Energy Storage System,” was authorized under announcement number CN 222619891 U, with a filing date of December 2023.
The patent summary indicates that the battery module consists of multiple batteries arranged sequentially in a first direction. In addition to the batteries, the battery pack includes thermal insulation components located between adjacent batteries. Specifically, the thermal insulation component features an insulating layer that offers excellent heat resistance, preventing heat transfer between neighboring batteries and inhibiting the spread of thermal runaway.
The insulating layer is also constructed to be elastic and has good compressibility. When the compressive strength applied to the insulating layer is between 0.5 MPa and 5.0 MPa, the remaining thickness of the insulating layer is maintained at 20% to 50% of the gap between the battery cells. This design allows the insulating layer to provide extra space for battery expansion, thereby alleviating the pressure on space caused by battery swelling. As a result, this can help slow down battery degradation and prolong its lifespan.
According to data from Tianyancha, Huawei Digital Energy Technology Co., Ltd. was established in 2021 and is based in Shenzhen. The company primarily engages in technology promotion and application services, with a registered capital of 300 million RMB. It has invested in four companies, participated in 132 bidding projects, and has a portfolio that includes 83 trademark registrations and 4,012 patents, along with nine administrative licenses.
