摘要:
A programmable turn signal and hazard flasher control system (10, 100) includes a lamp control module (12, 108) coupling a turn signal request unit (14, 106) to a number of turn signal lamps (20-30). The module (12, 108) couples the turn signal request unit (14, 106) to a number of vehicle turn signal lamps (20-26) in a first mode of operation and to a number of vehicle turn signal lamps (20-26) as well as a number of additional turn signal lamps (28, 30) in a second mode of operation to thereby accommodate lighting requirements of a trailer or other towed vehicle or to accommodate different lighting requirements in vehicles of a common vehicle platform. The load current to the turn signal lamps (20-30) in either case flows through a shunt resistor R1, and is controlled by a flasher circuit (54) during normal operation to a first flash rate and during a lamp failure condition to a second faster flash rate. The module (12, 108) further includes a control circuit (62) responsive to an appropriate signal state at a lamp designation control input (34) to provide a predefined load activation signal to the flasher circuit (54) regardless of whether the module (12, 108) is coupled to only a minimum number of vehicle turn signal lamps, or the minimum number of vehicle turn signal lamps as well as a number of additional turn signal lamps.
摘要:
A power safety system (PSS) includes a plurality of thermally-triggered electrical breaking arrangements (TTEBAs). The plurality of TTEBAs are associated with a plurality of electrical devices (EDs) disposed external to the PSS. The PSS further includes a plurality of electrical power connections (EPCs) associated with said plurality of TTEBAs that are configured to respectively electrically connect the PSS to the plurality of EDs. When at least one TTEBA in the plurality of TTEBAs is electrically operative and at least one thermal event occurs that is sufficient to thermally activate the at least one electrically operative TTEBA, at least the EPC associated with the at least one thermally activated TTEBA is electrically broken. A method to protect a human operator of the PSS from a thermal event is also presented. A PSS also extends to a primary and a secondary electrical charging system used to charge a battery of a vehicle.

An electric vehicle charge coupler for both mechanically and electrically coupling and decoupling a charger to a vehicle includes a handle. The handle includes a handle connector configured for manually coupling and decoupling the handle with an inlet connector disposed on the vehicle. The handle connector further defines an aperture. The handle also includes a light source configured for activation to emit light. When the light source is activated, light emits from the light source and passes through the aperture to illuminate an area directionally out from the aperture away from the handle connector.
摘要:
The handle of a charge coupler includes a mechanical latch that securely mechanically locks the handle to the vehicle passively when the handle is manually attached to the vehicle by a human operator to create an electrical connection between the vehicle and the charger. The handle also has an actuator movable by the operator from a deactivated state to a first and a second position activated state. The mechanical latch operates independently of the state of the actuator when the handle is being manually attached but being mechanically released by the actuator when it is moved to its second activated state. A non-contact electrical switch means associated with the actuator breaks the electrical connection when the actuator is moved to the first position activated state before releasing the mechanical latch at said second activated position.
