High current connection device for energy storage

摘要

The present invention relates to a high current connection device for contacting multiple energy storage units of an energy storage in parallel and/or in series, having the following characteristics: two poles for connecting the high current connection device to a current consumer, at least two positive terminal contacting connections for connecting to positive terminals of the energy storage units, at least two negative terminal contacting connections for connecting to negative terminals of the energy storage units, a printed circuit board for receiving the poles, the positive terminal contacting connections and the negative terminal contacting connections, and wherein each positive terminal contacting connection is assigned to one negative terminal contacting connection and one energy storage unit. Furthermore, the present invention relates to an energy storage in particular for hybrid vehicles, comprising multiple energy storage units, wherein the energy storage units are electrically connected in parallel and/or in series to each other by the high current connection device described above, and/or wherein the energy storage can be connected to a current consumer via the high current connection device.
