Products Power Electronics

LG Magna e-Powertrain has an inverter that efficiently controls the electric energy converted from the battery to the motor and an in-vehicle charger that supplies electricity to the battery stably and quickly based on its excellent technical capabilities and know-how in power conversion.

Reliable, Robust Conversion

An in-vehicle charger is a device that charges high-voltage batteries in the vehicle by converting commercial AC power supplied from outside to the vehicle to DC power. It consists of an input filter that reduces noise, a PFC that increases energy efficiency, a DC/DC converter that reliably powers the battery, and a control circuit that supports communication with other vehicles or electrical charging stations.
LG Magna e-Powertrain’s in-vehicle charger boasts high reliability and high efficiency of up to 95%. Products with output capacities of 3.6kW, 7.2kW, 11kW and bidirectional products are being produced. In particular, through V2G technology, bidirectional in-vehicle chargers can charge cars at lower prices at night and resell power at relatively higher prices during the day, producing profits by using idle power.
