摘要:
The device comprises a repositioning mechanism ( MR ) and a fixing mechanism ( MF ) joined by means of a control cable ( C ). The repositioning mechanism ( MR ) comprises a contact rod (10) linked to the contact key with two positions, parking and running, which correspond to the coupling of the key with the ignition switch, and a retention rod (11) joined to the cable ( C ). The fixing mechanism ( MF ) comprises a traction body joined to the lever (2), to its support (11) and to the cable ( C ). When the contact rod (10) and the retention rod (11) are coupled, the traction body (22) blocks the trigger (3) of the lever (2), thereby impeding its actuation. The decoupling of the contact key requires that the lever (2) is in the parking position producing automatically the coupling of both rods (10, 11).

摘要:
The invention refers to a system and method for assisting the start of an electrically powered vehicle comprising a battery and processing means configured to: a) receive a sequence of voltage measurements by a sensor connected between the high voltage terminals of the battery and a chassis, b) compare the sequence of voltage measurements received from the sensor with previously established voltage patterns, wherein each voltage pattern is formed by a sequence of voltage values, and wherein each voltage pattern is associated to an insulation resistance value, c) select the voltage pattern whose voltage values are closest to the voltage values of the sequence of voltage measurements received from the sensor, d) establish the insulation resistance value of the battery from selected voltage pattern, e) enable starting of the vehicle if the insulation resistance value obtained exceeds a predetermined insulation resistance threshold value that ensures the insulation of the battery.
摘要:
The present invention refers to an electric power supply system, comprising a power source (1) having first and second poles (2,3), a circuit breaker device (4) connected at the first pole (2) and a switch device (5) connected at the second pole (3). A control module (7) is adapted for sequentially opening and closing the circuit breaker and the switch device (4,5), such that the control module (7) would open or close the switch device (5) only when no current is flowing through the circuit breaker device (5). Since the switch device (5) would never break current flowing through the power source (1), it can be implemented as a switch of reduced size and reduced costs, such that the overall weight and cost of the system is reduced. The invention is preferably applied in the manufacture of battery packs for battery-powered vehicles.
