Abstract:
1. A method of controlling a grid blower to provide forced-air for a grid of resistive elements of a vehicle, the method comprising: generating an amount of electrical power across the grid of resistive elements based on an operation of the vehicle; operating a motor of the grid blower with the electrical power generated across the grid of resistive elements, the grid blower positioned proximate the grid of resistive elements and operated to blow air over the grid of resistive elements; and modulating at least some of the amount of electrical power to adjust at least one of a speed and a direction of the motor of the grid blower based on an operating condition; wherein the operation of the vehicle includes a dynamic braking operation in which the amount of electrical power is generated by a traction motor, and wherein operating the motor of the grid blower comprises operating the motor of the grid blower at a speed independent of the amount of electrical power generated across the grid of resistive elements.
