The invention provides a universal high voltage connection device for an energy storage system. The device includes an insulation base, an insulation protective cover, a special-shaped copper row, a first connecting copper row and a second connecting copper row, wherein a cover plate is arranged on one side of the insulation base, a protective cavity is formed inside the cover plate, the insulation protective cover is detachably connected with the cover plate to seal the protective cavity, the special-shaped copper row, the first connecting copper row and the second connecting copper row are all disposed in the protective cavity, the special-shaped copper row is perpendicularly connected with the insulation base, one end thereof extends out of the insulation base, the first connecting copper row is disposed on a side of the special-shaped copper row and arranged along the length direction of the special-shaped copper row, the second connecting copper row is disposed on a side of the special-shaped copper row adjacent to the insulation protective cover and perpendicular to the special-shaped copper row, and the first connecting copper row and the second connecting copper row are connected with the special-shaped copper row. The device is advantaged in that the device meets universal wiring requirements of different rated currents, further serves as a purpose of convergence, cannot only meet requirements of a wiring harness connection method, but also can be used as copper row connection requirements, and thereby internal resistance of the system is reduced.
Description
technical field [0001] The invention relates to the technical field of high-voltage and high-current connectors, in particular to a universal high-voltage connection device for an energy storage system. Background technique [0002] With the promotion of electrochemical energy storage technology, the requirements for connection devices used in energy storage are somewhat different from those used in new energy vehicles and other power sources, such as low waterproof and no need for electromagnetic shielding. The voltage of the energy storage system is generally above 1000V, and it has higher requirements for the structure and safety of the connecting device. Creepage distance and electrical clearance are all factors that need to be considered. [0003] Common connection devices such as battery trays and energy storage cabinets used in the field of high-voltage energy storage all adopt the male terminal and female terminal mating mode, and the manufacture is complicated and t...
