Compact power converter maximises driving range for e-cars
The inverters from Eaton’s eMobility business draw electricity from the battery and control how it is applied to the motor to manage power and torque, and will be tested by a global automaker in the first quarter 2019.
The inverters have a power density of 35 kilowatts per litre and 98 per cent operating efficiency, helping to maximise range while taking up minimal space in the vehicle.
“Most global automakers have different vehicle electrification strategies, so the products we develop must support a range of applications. Regardless of the strategy, electric vehicles need efficient and compact power electronics, and our new line of efficient inverters can be tailored to a wide range of customer requirements and applications,” said Scott Adams, senior vice president at eMobility. “The inverter market for electric vehicles is still emerging,” he said. “Among our advantages in this market are our established partnerships with key suppliers of power electronic components and the fact that our inverters comply with the critical ISO 26262 standard for functional safety.”
Eaton projects EVs will make up 38 per cent of the global passenger car market by 2030, shared between battery electric, plug-in hybrid, hybrid-electric and mild-hybrid electric. Eaton’s inverters can be used in all types of electric vehicles, as well as other alternative fuel vehicles, such as hydrogen fuel cell cars. Eaton has a number of vehicle electrification products in the market, including DC-DC converters, power distribution units, battery-electric transmissions and high-voltage fuses.
