An electrical energy supply system for use in an electric vehicle comprises a tank 1 and a detector. The tank 1 contains a multiplicity of batteries 3 which are not fastened to each other, and configured to deliver electrical energy from the batteries 3 to other systems of the vehicle. The tank 1 includes a release system configured to release the batteries 3 from the tank 1 and from the vehicle. The detector is configured to detect a condition of the vehicle and/or the batteries 3 which could cause the batteries 3 to become hazardous, and to cause the release system to release the batteries 3 in response to detecting the hazardous condition. The detector may comprise any one or more of: an accelerometer configured to detect a collision involving the vehicle; a temperature sensor to monitor temperature of the batteries 3 and/or the tank; a smoke detector; an airbag control unit (ACU); and a monitor for monitoring electrical inputs to and/or outputs from the tank. The detector may detect thermal runaway of the batteries 3.
