Abstract
The present disclosure relates to a sub-system for a vehicle comprising an electrical power bus (12, 14, 16) for distributing electrical power from an electrical energy storage means (10) to various different electrical components of the vehicle, such as a combined electric traction motor/generator (20). The sub-system comprises means for disconnecting the electrical energy storage means (10) from the bus (12, 14, 16), means (6) for measuring the potential difference between a rail of the bus of a first polarity and a chassis (18) of the vehicle, and means (4) for connecting the rail of the bus of the first polarity to the chassis (18) or a terminal of the electrical energy storage means of opposite polarity if the potential difference between the rail of the bus of the first polarity and the chassis is measured to be greater than a predetermined level, until the potential difference between the rail of the bus of the first polarity and the chassis is less than the predetermined level, then disconnecting the rail from the chassis or the terminal of the electrical energy storage means of opposite polarity, wherein the means (6) for connecting the rail of the bus to, then disconnecti…
