Abstract: There is disclosed a safety arrangement (1) for a motor vehicle having an electric battery (2) and an occupant safety device(6) such as an airbag (7) or seat-belt pre-tensioner. The arrangement (1) comprises a crash sensor (10) responsive to acceleration, a battery sensor (13-17) arranged to monitor a battery parameter indicative of the condition of the battery, an actuator (8) for activating the occupant safety device(6), and a single control unit (9) operable to receive and process signals (x,b) from both the crash sensor(10) and the battery sensor(13-17). The control unit (9) is operable to issue an actuating command to the actuator (8) to activate the occupant safety device (6) in response to a signal x from the crash sensor. In a preferred embodiment, there is provided a second actuator (23,24,25) for activating a battery safety device(20,21,22); the control unit (9) being operable to issue an actuating command to said second actuator to activate the battery safety device upon receipt of both i) a signal (x) from the or at least one said crash sensor exceeding a predetermined threshold value X 1 and a ii) a signal b from the or at least one said battery sensor satisfying a predetermined criterion.
