A regenerative elevator drive (2) is arranged to receive power from, and supply regenerative energy to, an external power supply (4, 10) and is arranged to direct excess regenerative energy through a dynamic braking resistor (20). An inverter (16) is arranged to receive a DC voltage, derived from the external power supply (4, 10), and to convert the DC voltage to an AC voltage for output to an external motor (22). A DC link capacitor (14) is connected across the input of the inverter (16). A circuit breaker unit (54) is arranged to switch between a first state which provides a connection between the inverter (16) and the external power supply (4, 10), and a second state which disconnects the inverter (16) from the external power supply (4,10). The circuit breaker unit (54) is arranged to provide a discharge path from the DC link capacitor (14) via the dynamic braking resistor (2) only in the second state. The drive (2) may also determine the state-of-health and/or the expected end of life of the battery (10) by passing a current from the battery (10) through the dynamic braking resistor (20).
