  • Patent number: 6211577
    Abstract: A jump start circuit (26) for electrical connection between a battery (12) of a motor vehicle and jump start terminals (22,24) in the motor vehicle, the jump start circuit comprising a switch (28) for positioning in an electrical line (18) between one (22) of the jump start terminals and the battery, the switch being biased to a normally open position; and a logic circuit (32) having means for monitoring the polarity of a voltage across the jump start terminals, means for closing the switch on detection of a predetermined polarity, and a timer circuit for opening the switch after closing for a predetermined period of time. Provides protection against incorrect polarity connection during jump starting.

  • Patent number: 6087737
    Abstract: A battery disconnection system (10) comprising a first electrical conductor (12) electrically connectable to a terminal of a battery; a second electrical conductor (16) electrically connectable to an electrical load (18); a first electrical contact (22) attached to the first electrical conductor; a second electrical contact (24) attached to the second electrical conductor; electrical connecting means (22) reciprocally movable in an axial direction (A) between a first position in which the connecting means electrically connects the first and second contacts and a second position in which the first and second contacts are disconnected; electric drive means (26) for moving the connecting means from the first position to the second position on receipt of a predetermined signal. The predetermined signal may be generated by a crash sensor, anti-theft device, or other adverse condition sensor, or a manually operable switch.
