Storage system for the storage of electric energy for a vehicle with electric propulsion

摘要

A storage system for the storage of electric energy for a vehicle with electric propulsion; the storage system has: a plurality of chemical batteries, which are divided into groups, each of which comprises chemical batteries connected to each other in series and/or in parallel; and two rigid busbars, which connect the groups of chemical batteries in parallel and have respective connection portions, which constitute the connection terminals of the storage system to the outside; each rigid busbar has a variable cross section, which increases close to the connection portion, so that the cross section of each busbar is the largest at the connection portion and the smallest in correspondence to the end which lies the farthest from the connection portion.

1. A storage system for the storage of electric energy for a vehicle with electric propulsion, the storage system comprising:
a plurality of electrochemical batteries, which are divided into groups, each of which group comprises electrochemical batteries electrically connected to each other; and two rigid busbars, which electrically connect the groups of electrochemical batteries in parallel and present respective connection portion, which constitute connection terminals of the storage system; wherein each rigid busbar presents a variable cross section, which increases in size towards the connection portion, so that the cross section of each rigid busbar is largest proximate to the connection portion and smallest at an end distal to the connection portion; and wherein each rigid busbar presents a stepped variable cross section, which increases in steps upstream and in proximity to a connection point of each group of electrochemical batteries.
