The rules for the emergency shutoff switch state: "All vehicles must have an external emergency shutdown switch that isolates the battery from the other electrical components when actuated. This emergency shutdown switch must be rated for the appropriate voltage and current of the vehicle’s electrical system. The emergency shutdown switch must be positioned on the exterior of the vehicle, clearly indicated, and easily actuated."
We are using a Bosch mid-drive motor, and there is a power-off button on the display kiosk that disconnects the battery from the motor. Will this suffice, or do we need an additional external kill switch?
