The present disclosure provides a capacitor module including: a capacitor; a first housing having a hexahedron shape and having an inner space in which the capacitor is disposed, the first housing including a pair of cooling parts recessed inwards from a pair of parallel surfaces among outer side surfaces thereof such that a refrigerant flows, a pair of cooling channels disposed inside opposite side surfaces perpendicular to the surfaces of the pair of cooling parts such that the pair of cooling parts communicate with each other, and a through-hole configured to connect each of the cooling channels to the outside such that the refrigerant is introduced or discharged therethrough; and a cooling plate coupled to the first housing so as to seal the cooling parts.

Capacitor module, power conversion device, and motor assembly including same

A converter for a vehicle including an inductor which includes at least one coil, a core including a first region having an annular planar shape, around which the at least one coil is wound, and a second region having at least one first through-hole, a case accommodating the at least one coil and the core and including at least one cooling rod inserted into the at least one first through-hole, and a fixing bolt fastened to the at least one cooling rod exposed through the at least one first through-hole to fix the core to the case.

Converter for vehicle

A system and method for controlling energy of an eco-friendly vehicle are provided and include turning off, by a controller, a main relay in response to sensing interlock by means of a detection circuit and charging a secondary batter by discharging voltage of a capacitor in an inverter to the secondary battery, under control of voltage output from a low voltage DC converter after the main relay is turned off. In addition, the controller is configured to discharge DC-link voltage to a driving motor by operating the inverter after charging the second battery.

System and method for controlling energy under interlock of eco-friendly vehicle

A fault diagnosing system method for a coolant switching device for a vehicle are provided. The fault diagnosing system includes a first coolant pipe line that passes through an electronic device and an interior heating device. A second coolant pipe line branches off the first coolant pipe line and passes through a radiator. In addition, a coolant switching device is disposed at a branching point at which the second coolant pipe line branches off the first coolant pipe line and an on-board charger charges a vehicle battery and is disposed on the second pipe line. A controller is configured to determine a failure of the coolant switching device and stop the on-board charger from charging the vehicle battery when a temperature of the on-board charger is greater than a first set temperature and a temperature of the electronic device is less than a second set temperature.
