Modern electric boats glide emission-free and almost noiselessly across the water. The drive controller is powered by a battery storage system. This supplies the motor
for the main drive with the necessary energy and is also the energy source for the entire on-board power supply.
The drive controller can‘t be started directly from the battery storage system.
The drive controller should be started with a precharging resistor, so that problem-free operation of the electric boat with the battery storage is made possible.
Without the resistor, the drive controller and therefore the ship‘s engine cannot be started.
