he specialty converter works in conjunction with another converter that takes power from the battery electric vehicle’s (BEV) 600-volt system and steps it down to 24 volts. The unit will power accessories, such as antilock brakes and lighting. It is an exciting innovation not yet destined for the Asia-Pacific but puts importers of electric trucks here on notice. The BEV equalizer will be sold in the North American and China markets beginning later this year. “DC-DC converters are an essential part of our eMobility product portfolio and are used in a variety of vehicle applications,” said Pratik Trivedi, general manager, Eaton’s eMobility business. “Like traditional vehicles, electrified vehicles have low-voltage loads on boardlike infotainment systems, GPS and safety devices. Efficiently converting power from high to low is key, but it is also important to have a secondary converter to provide power to the traditional 12-volt loads. “We’re delighted to bring our proven power-conversion technology to this new, innovative electric-truck platform.” The battery equalizer works in conjunction with
Industry gets serious about electric trucks Eaton’s eMobility business has been awarded a contract to supply a 24-to-12 volt DC-DC converter for use in a commercial heavy-duty battery electric vehicle eMobility converter Features • Easily implemented into a system providing 24V power from a 12V input allowing use of 12V and 24V components on a vehicle • Allows use of 24V electrical components in a 12V electrical system providing greater system flexibility • With a low standby current of 0.7mA power is not used by the DC Converter when it is not required. • Clean output power able to power sensitive loads including radios and controllers • Proven reliability with over 500,000 fielded units another converter that takes power from the BEV’s 600-volt system and steps it down to 24 volts. The eMobility unit then takes it down to 12 volts for use in low-voltage systems and to power a backup 12-

volt battery in case of a fault in the main power supply. Having this equaliser function, the 12-volt battery and a split 24-volt battery system ensures essential safety equipment can operate on 12 volts in the event of a power failure. That capability makes the converter unique among product offerings in this space. Eaton’s DC-DC converter also includes noise reduction and interference rejec-
tion so there is no interference between the unit and vehicle electronics. “The converter is rugged and robust, providing a seal against environmental factors, such as salt spray and water, and has high vibration resiliency,” said Trivedi. “It is an ideal solution for manufacturers that require a dependable method to power traditional vehicle components in high-power battery electric vehicles.”
