Abstract

The present invention discloses a plug-in vehicle battery busbar assembly. The plug-in vehicle battery busbar assembly includes a round C-shaped busbar and one or two U-shaped elastic connectors. The round C-shaped busbar includes a straight section and an arc section. A section of an inner cavity of the arc section is C-shaped. The U-shaped elastic connector includes a straight section and a dome-shaped section. The dome-shaped section is connected with the bottom end of the straight section. The width of the straight section is slightly smaller than the width of the base of the dome-shaped section. The width of the straight section of the U-shaped elastic connector is equivalent to an opening width of the inner cavity of the straight section of the round C-shaped busbar. The U-shaped elastic connector is inserted into the inner cavity of the round C-shaped busbar, so that the straight section of the U-shaped elastic connector is tightly fitted with the inner cavity of the straight section of the round C-shaped busbar. The whole inner cavity of the round C-shaped busbar can be used for accommodating the connector, a plurality of connectors that are inserted in parallel are available, sufficient battery packs can be accommodated, the capacity of a single battery pack can be lowered, and the impact of a battery fault on a power system is lowered.

Description

technical field [0001] The invention relates to a plug-in vehicle battery bus bar assembly. Background technique [0002] With the improvement of people's awareness of environmental protection, electric vehicles with zero emissions can be promoted. However, the range, efficiency and longevity of the batteries that power electric vehicles have been hindering the mass adoption of electric vehicles. At present, the most common electric vehicle is a lithium battery as a power source. Except for Tesla's electric vehicles that can reach a cruising range of 400km, general electric vehicles only have a cruising range of 50km-150km in pure electric mode. The car power supply is composed of 6-12 battery packs, and the busbars and copper bars are fixedly connected. First of all, due to the small number of battery packs and the large capacity of a single battery pack, once a single battery in the battery pack fails, it will affect the function of the entire battery pack and have a gr...
