JinkoSolar has applied for a patent for a battery pack that aims to reduce the length of wire harnesses and optimize wiring methods. According to the information from the National Intellectual Property Administration, JinkoSolar Co., Ltd. and Zhejiang Jinko Energy Storage Co., Ltd. filed a patent application titled “A Battery Pack,” with the publication number CN120073214A, on February 2025.
The patent summary indicates that the battery pack comprises at least two battery modules and a wire harness for electrically connecting multiple battery modules. Additionally, the battery pack includes a battery management unit, with at least the first battery module directly electrically connected to this management unit. Each battery module consists of integrated busbars and battery cells, with the first battery module featuring a first circuit board. This circuit board includes at least a first wiring layer and a second wiring layer. The first wiring layer is designed to transmit signals from the first battery module to the battery management unit, while the second wiring layer connects to other adjacent battery modules, allowing signals to be relayed to the battery management unit.
The first battery module within the battery pack is equipped with at least two wiring layers, facilitating signal transmission from the battery module located farthest from the battery management unit to those that are closer. This innovation is advantageous in reducing the length of wire harnesses and optimizing wiring arrangements.
