E-Mobility

Safe Power Control for E-Mobility and Commercial Vehicles

Panasonic DCDC converters are used in electrified powertrains to manage bi-directional energy flow between high-voltage batteries and 12/24(48V vehicle systems. They ensure stable power supply to essential components, enable energy recuperation, and support high-power auxiliary loads.

Our bidirectional DCDC converters are specifically designed for commercial vehicle applications, ensuring efficient energy management and reliable performance. They are used primarily in Trucks, Construction Vehicles, and Agriculture machinery. These converters optimize power flow between batteries and auxiliary systems, providing enhanced durability and adaptability to demanding operational conditions. Features such as robust thermal management and high efficiency support the heavy-duty requirements of commercial vehicles across various industries.

Low-Voltage

Mild-Hybrid Systems (24V/48V)

In mild-hybrid vehicles, LV DCDC converters transform recuperated energy from 24V or 48V lithium-ion batteries into 12V power. This supports conventional vehicle electronics while improving fuel efficiency and reducing emissions.
