eMobility Power Supplies

Bel eMobility power supplies support a range of eMobility applications, from hybrid to medium and heavy-duty vehicles, while optimizing for efficiency and durability. Bel offers a variety of electric vehicle power solutions to fit users’ requirements, including DC-DC converters, onboard battery chargers, DC-AC inverters, and custom products.

eMobility battery chargers are 25 kW onboard liquid-cooled battery chargers that convert 3-phase AC (330 V_AC to 525 V_AC) to DC voltage 250 V_DC to 800 V_DC). They can be paralleled up to four units in charge mode, can be connected to an EVSE charging station or directly to the public grid, and are bidirectional units with high efficiency in a compact design.

eMobility combo units are all-in-one eMobility liquid-cooled products that include a single phase/split phase inverter and charger, a DC/DC converter with an output voltage of 12 V_DC and 4 kW of output power, and a DC/DC converter with an output voltage of 24 V_DC and 1 kW of output power.

eMobility DC/DC converters are DC/DC power supplies that convert high-voltage direct current (HV_DC) in hybrid and electric vehicles to low-voltage direct current (LV_DC) suitable for powering low-voltage (12 V_DC to 24 V_DC) accessories, allowing HV_DC bus voltages to be utilized to drive low-voltage automotive accessories. These converters are a replacement for an alternator in ICE vehicles.

eMobility DC/AC inverters are highly efficient, converting high-voltage DC power into single phase/split phase AC power required to drive AC accessory loads directly from the high-voltage DC drives or battery bus. They allow HV_DC bus voltages to be utilized for 120 V_AC or 240 V_AC accessories and feature exportable pure sine wave AC power (50 Hz to 60 Hz).
