A battery pack includes a battery housing, a positive terminal, a negative terminal, a plurality of cell module assemblies, and a battery management system. The plurality of cell module assemblies are received within an internal cavity of the battery housing, and include a plurality of lithium-ion battery cells that are connected in parallel. The battery management system is in communication with at least one of the plurality of cell module assemblies within the internal cavity, and is structured to receive a voltage tap measurement from each of the plurality of cell module assemblies within the internal cavity, compare the voltage tap measurement from each of the plurality of cell module assemblies to an expected voltage tap measurement, and determine if a voltage tap measurement for a cell module assembly within the plurality of cell module assemblies deviates from the expected voltage tap measurement to identify a faulty cell module assembly.

A wiring module includes a flexible substrate, a sensor component (temperature sensor), a connecting member (bus bar), and a holding part-equipped relay member, wherein the holding part-equipped relay member includes: a relay member main body including a base part (first main plate) that is to be fixed to the flexible substrate and the bus bar, and a holding part (first holding piece) that is continuous with the first main plate; a pedestal part (housing) that is to be held by the first holding piece so as to be displaceable in a direction toward or away from the first main plate, and that is to be fixed to a position of the flexible substrate where the temperature sensor is mounted; and a biasing member that has elastic force, that has one end held by the first main plate, and that biases the housing in the direction away from the first main plate.

The present invention is directed to an outdoor blower that is capable of safely releasing any electrostatic charge that builds up in the blower. During the operation of the blower, electric charge builds up in the housing and components of the blower as particles in the air are moved through the blower. The blower includes a wire contact in the handle that is electrically connected to various other components in the blower. As electric charge is built up in the blower, it can be passed to the wire contact, which is graspable by a user, who acts as a ground and is able to release any charge that builds up.

A battery pack includes: a connector holder that is fixed to an exterior case and has two main surfaces that include a first main surface exposed through an opening of the exterior case; a floating connector connected with a center of the connector holder in such a manner that the floating connector floats in such a manner that an orientation or a position of the floating connector is variable upward, downward, leftward, and rightward; a lead wire fixed to an inner surface of the floating connector, the lead wire extending through an inside of the exterior case, and the lead wire connecting floating connector with a circuit board; and a positioning buffer that pushes the floating connector, and positions the floating connector at a predetermined original state when an external force is not applied to the floating connector.

The present disclosure provides a battery housing including a recess and a communication wiring socket. The recess is recessed inward from a side wall of the battery housing. The communication wiring socket is provided on an inner wall of the recess and configured to connect with a battery management system disposed within the battery housing. The recess is configured to provide a handheld space and to receive a communication wiring terminal plugged into the communication wiring socket. The present disclosure further provides an energy storage battery including the battery housing, and an energy storage system including the energy storage battery.

A power supply system (10) is used for supplying power to a power system of an electric tractor and comprises a bracket (100) that is provided above and below a frame of a transport trailer, first cases (200) that are provided on the bracket and first power battery packs that are suspended inside the first case. Each of the first cases is provided with a first ventilation structure and a second ventilation structure (211) so that while the transport trailer is moving, wind can enter the first case from the first ventilation structure and be discharged from the second ventilation structure, thus achieving further cooling and heat dissipation for the first power battery packs and avoiding service life being impacted due to the first power battery pack overheating.
