Water-Cooled Braking Resistor

One of the company’s latest projects is to provide braking capacity for a new hybrid farm vehicle.

The vehicle utilises 4 x 33kW motors to drive each wheel separately with active slip control on each. As with most electrical and hybrid vehicles, the braking is a combination of conventional friction brakes and regenerative braking, with an REO water cooled braking resistor to handle emergency conditions.

For this project not only did REO have to ensure that the water cooled resistor was able to dissipate the required electrical power in all conditions, but that the mechanical construction of the resistor was robust enough to withstand the environmental aspects of being mounted on a moving vehicle.
