A SYSTEM FOR REDUCING THE POWER IN A BATTERY STACK ARRANGEMENT

摘要

The present invention relates to a system for breaking an electric circuit in a battery stack arranged in a vehicle, wherein said battery stack comprises a plurality of batteries, each battery comprises at least one battery cell connected to a positive terminal and a negative terminal. An electric current flows between the positive terminal and a negative terminal of adjacently arranged batteries during operation. The system comprises: an impact recognition device and at least one interrupt mechanism. The interrupt mechanism is arranged to break the electric circuit in the battery stack in order to divide said battery stack into several battery sub-stacks, each sub- stack comprising at least one battery, when said impact recognition device detects an impact.
