Abstract
A charge interlock system of an electronic device includes a drive system, a relay coupled to the drive system, and a controller. The controller receives an indication that the electric device is in a charging mode. The controller also transmits signals to open the relay. Moreover, the controller determines that the drive system is disabled based at least in part on the open relay.
Claims20
A charge interlock system of an electric device, the charge interlock system comprising:
- a drive system;
- a relay configured to control an electrical circuit of the drive system and a braking system associated with a brake of the electric device;
- and
- a controller configured to:
- receive an indication that the electric device is in a charging mode;
- transmit a signal configured to cause the relay to open in response to receiving the indication that the electric device is in the charging mode, wherein opening the relay disables the drive system and activates the brake;
- and
- determine that the drive system is disabled and the brake is activated based at least in part on the open relay.
5 more elements
A method, comprising:
- determining that an electric feature is charging;
- and
- in response to the determination that the electric feature is charging, causing a relay disposed along an electrical circuit connecting a drive system of the electric feature to a power source of the electric feature to open, wherein causing the relay to open disconnects the drive system and connects a braking system to disable movement of the electric feature.
A relay of an electric vehicle, the relay configured to:
- in response to an indication that the electric vehicle is in a charging mode, opening a switch along a circuit including a drive system of the electric vehicle, causing the drive system to be disabled and a braking system of the electric vehicle to be enabled;
- and
- in response to an indication that the electric vehicle is in a non-charging mode, closing the switch, causing the drive system to be enabled and the braking system to be disabled.
