Abstract

A battery having an integral emergency circuit breaker for preventing the transmission of electrical current from the battery to a vehicle in which the battery is connected in an electric circuit. The battery is connected in the circuit so its negative terminal is grounded, and its positive terminal is ungrounded, under normal conditions. The battery has an impact resistant case for shielding the contents thereof from electrical contact with the structure of the vehicle in the event of an accident. A fuse link is provided for interrupting the flow of electrical current from the positive pole of the charge storage section to the positive terminal of the battery in response to an increase in the electrical current flowing through the fuse link. The first end of the fuse link is connected to the positive pole of the charge storage section and the second end of the fuse link is connected to the exposed positive terminal. The fuse link permits the flow of current therethrough to the positive battery terminal under normal conditions. In response to perturbation of the vehicle by an accident, a switch connects the second end of the fuse link to the negative pole of the storage section so …
