This paper shows the new approach for protection of electric energy storage batteries in order to prevent heavy damage in case of sever electrical fault, e.g. direct short circuit on the battery. Existing solutions with Pyroswitches with parallel Fuses has disadvantages. Proposed paper presents battery over-current protection system with specially designed Pyroswitch and melting Fuse in parallel. This connection can be triggered externally and it is able to cover all time-current circumstances. Additionally, it is able to provide the discharging process for DC-link capacitor.
