A charge monitor for a battery (e.g. the battery of a battery powered vehicle) comprises a transducer (20) monitoring the current flowing into or from the battery, a visual display (16) and a microprocessor control circuit (10) to track the amount of charge in the battery at all times and for driving the visual display accordingly. The monitor is able to take account of charge put back into the battery during regenerative braking and is able to track and display a number of items of information relating to the battery, in addition to its instantaneous charge, e.g. the distance which may be travelled at the current speed, the number of hours of usage remaining, whether the economy of use in improving or deteriorating, the number of battery charges and discharges and an indication of excessive current drain.
