DC to DC converters for battery-electric trucks
Eaton’s eMobility business will supply a 24-to-12-volt DC-DC converter to power accessories like antilock brakes and lighting in commercial heavy-duty battery-electric vehicles.
The specialty converter, also known as a battery equalizer, works alongside another converter that takes power from a vehicle’s 600-volt system and steps it down to 24 volts. The eMobility unit then takes it down to 12 volts for low-voltage systems and to power a backup 12-volt battery that’s on hand in case there’s a fault in the main power supply.
Having this equalizer 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, Eaton says.
Eaton’s DC-DC converter also includes noise reduction and interference rejection to protect against interference with vehicle electronics.
The converter has also been sealed against environmental contaminants such as salt spray and water, and it’s protected against high vibrations.
