Hanjoo Metal supplies more than 100 unique products to world leading automobile companies.
Electric vehicles (EV) and the hybrid cars uses an electric motor as the main source or as an assisting source of power. In order to cool the heat generated while the motor is running, the motor is surrounded by a complex water-cooling circuit. The motor housing must allow water to flow in the motor while maintaining the motor coil isolated all the while providing electrical circuits and driving within the structure. The design rerquires hollow aluminum casting production technology, which is created utilizing diverse and complex core and casting design technoloy. Currently such housing is being supplied to automotive companies overseas.
Battery housing is necessary for electric vehicles or hybrid electric cars that utilize a battery pack that can store electrical energy. Such battery housing should consider not only the weight of the battery but should also isolate/protect the battery pack from the vehicle and the surrounding external environment while it is in operation. Advanced aluminum low pressure casting technology to produce a large case with an integrated battery.
In order to control the motor in an electric vehicle, it is necessary to convert the direct current (DC) power of the battery into an alternating current (AC) by using an inverter. The housing should hold the inverter fixed, be capable of withstuding external shock, isolate electric compoents from the external environment, and cool the heat generated by the electrical circuit.
