Abstract: The present disclosure relates to a battery module. The battery module includes a plurality of battery units connected in series; an electrode output connecting piece disposed at an output end of the plurality of battery units; a plurality of bridging busbars, each connecting two battery units spaced by another battery unit or more battery units among the plurality of battery units; and an adjacent busbar connecting adjacent battery units among the plurality of battery units. An electrical connection path is formed in the battery module by the electrode output connecting piece, the bridging busbars and the adjacent busbar. At least two of the plurality of bridging busbars partially overlap and fit one another in an electrical insulation manner as a group. The battery module according to the present disclosure is applicable in diverse situations, and capable of improving safety performance and energy density.

Abstract: Disclosed are a load state detection circuit and method. A microcontroller is connected to a switch unit which is connected between a detecting power supply and a load to be tested. A voltage sampling point is formed at either terminal of the load to be tested, and the voltage sampling circuit is connected between the voltage sampling point and the microcontroller. The voltage sampling circuit is configured to sample a voltage at the voltage sampling point. The microcontroller is configured to connect the load to be tested and the detecting power supply by controlling the switch unit, and determine whether a fault exists in the load to be tested according to a received voltage at the voltage sampling point sampled by the voltage sampling circuit, before connecting the load to be tested with the drive power supply.
