Hybrid electric vehicle battery lockout plug
View Patent ↗A battery lockout device is provided. The battery lockout device may include a safety plug body adapted to engage a power port of the battery. The battery lockout device may further include a rotating member operatively connected to the safety plug body, the rotating member engaging a battery lip or battery lip housing. The rotating member, in a first rotated position, can be locked in the first rotated position preventing access to the power port of the battery and preventing removal of the safety body plug from the battery. To effectuate locking the rotating member in the first rotated position, a keyed lock can be used to maintain the first rotated position of the rotating member relative to the safety plug body and the battery/battery housing lip. In this way, no energy from the battery may be discharged until removal/disengagement of the battery lockout device.
1. A device, comprising:
a safety plug body adapted to engage a power port of a battery and prevent discharge of energy stored in the battery; and
a locking element movably attached to the safety plug body to rotate about an axis perpendicular to a length of the safety plug body, adapted to prevent removal of the safety plug body from the power port of the battery.
2. The device of claim 1 , wherein the device accepts a lock through respective apertures of the safety plug body and the locking element, the respective apertures lining up with one another when the locking element in a first rotated position.
3. The device of claim 2 , wherein the locking element comprises an engagement member at an end of the locking element distal from its respective aperture.
4. The device of claim 3 , wherein the engagement member engages a lip of the battery or a lip of a housing for the battery, preventing the removal of the safety plug body.
5. A lockout plug assembly, comprising:
a first member comprising a battery port connector of a battery; and
a second member comprising a locking jaw, the locking jaw accepting a lock when rotated in a first direction about an axis perpendicular to and through a length of the first member, and engaging a battery housing preventing removal of the lockout plug assembly from the battery.
6. The lockout plug assembly of claim 5 , wherein the first and second members are rotatably connected with a connecting member passing through respective connection apertures of the first and second members.
7. The lockout plug assembly of claim 6 , wherein respective lock apertures coincide when rotated in the first direction, and wherein the lock passes through both the first and second members via the respective lock apertures.
8. The lockout plug assembly of claim 7 , wherein the respective lock apertures are position at first ends of the first and second members distal from second ends of the first and second members, the second end of the second member comprising the locking jaw.
9. The lockout plug assembly of claim 5 , wherein the locking jaw disengages the battery housing when rotated in a second direction.
10. The device of claim 1 , wherein the locking element comprises a lip latch to align with the longitudinal sides of the safety plug body.
