CONTROL APPARATUS FOR ELECTRIC CAR

摘要

A control apparatus for an electric car (10) controls a power supply system of the electric car (10) that includes a first DC power supply apparatus (20) for supplying a DC power to a traction inverter (50) and also includes a second DC power supply apparatus (30) parallel connected to the first DC power supply apparatus (20) via a DC/DC converter (40). The control apparatus has a relay (70) that interrupts the power supply from the first DC power supply apparatus (20) to the traction inverter (50) in synchronism with an activation of a self-protection circuit (51) of the traction inverter (50) when the self-protection circuit (51) is activated in response to an excessive current from the first DC power supply apparatus (20).
