In our lab, we power minivan power folding seats with 0 - 20V 0 - 50A DC Power Supply. These power folding seats are powered with DC Motors.
Before we release our embedded controller that controls the seat travel, we test with real minivan vehicle battery? Why is it necessary to test with real vehicle battery? Isn't the voltage in vehicle battery fixed? If yes, we can just dial that fixed voltage in our bench power supply. Why do we need to test with real vehicle battery ?
