Method of providing a battery pack system

[0001] The present invention relates to a method for providing a battery pack system, and more particularly, to a method for providing a battery pack system for mounting a battery pack for an AMR (Autonomous Mobile Robot) autonomous driving robot, the battery pack including a stable power supply cut-off function of a BDU and a circuit module that distributes power required for a robot such as an AMR according to a power value, on the AMR battery pack.

[0002] A key component of a battery pack is the module that connects and disconnects power. It is crucial to design and build a mass production system for these modules, enabling them to be installed on a variety of electric vehicle platforms. This will increase productivity and price competitiveness. In particular, it is crucial to provide battery packs for AMRs that incorporate a BDU's stable power supply disconnection function and a circuit module that distributes the power required by robots like AMRs according to their power levels.

[0003] The problem to be solved by the present invention is to provide a battery pack for AMR that can be installed on various electric vehicle platforms, has high mass production and thus high productivity and price competitiveness, and has a stable power supply cut-off function of a BDU and a circuit module that distributes the power required for a robot such as an AMR according to the power value.

[0004] In addition, the battery pack provides a solution to the complex wiring problem of existing robot battery packs, which require separate relay arrangements for battery cells and BMS and power distribution to each sensor.

[0005] Additionally, it provides a battery pack that integrates battery cells, BMS, and BDU (relay function) power distribution device, allowing the sensor to be directly connected to the required power source without separate wiring.

[0006] In addition, for a processor equipped with a battery pack for AMR, the battery pack is provided with both quality improvement and stability guaranteed by performing a combination of initial inspection, inspection under adverse temperature conditions, and protective sealing for movement after the inspection.

[0007] In addition, it initiates a unique setup operation for battery pack inspection, so that inspection, temperature maintenance, exterior protection, temporary storage, and movement of the optimized battery pack can be sequentially and complexly linked.
