    摘要： A vehicle anti-theft system that disables a vehicle engine upon detection of an unauthorized vehicle start-up, after the engine is running, by disconnecting the vehicle battery and draining the vehicle electrical system voltage to ground through a resistor. When the system is armed, it monitors whether the engine is running and has been recently started by detecting vibrations, fluctuations in the VES voltage, and the actual VES voltage. The system includes an electro-mechanical switch that has a battery internal contact, a vehicle electrical system, the standard battery external terminal, contact and a disconnect contact. When the switch is connected to the battery contact, the vehicle battery is connected in the circuit. When the switch is connected to the vehicle electrical system contact, the system is connected to ground through a resistance and the battery is disconnected from circuit. When the switch is connected to the disconnect contact, the battery is disconnected and the vehicle electrical system is not connected to ground. When the switch is not energized, it is either connected to the battery contact or the disconnect contact. When the switch is energized, the switch will switch to the vehicle electrical system contact, and then when it is deenergized, it will switch to the opposite battery contact or disconnect contact. The system includes logic so that if the engine is running and has been recently started when it is armed, the system will energize the switch to disconnect it from the battery contact and connect it to the vehicle electrical system contact for a predetermined time to drain the electrical system voltage to ground.

    摘要： A vehicle anti-theft system that disables a vehicle engine upon detection of an unauthorized vehicle start-up, after the engine is running, by disconnecting the vehicle battery and draining the alternator voltage to ground through a resistor. A fob transmitter transmits a coded frequency signal that is received by a receiver associated with the anti-theft system to arm the system. When the system is armed, it monitors whether the engine is running and has been recently started using a combination of vibration detection, voltage fluctuations in the battery voltage and the actual battery voltage. If the system determines that the engine is running and has been recently started, the system will issue a first command that opens a relay switch to disconnect the battery and a second command that closes a switch to connect the alternator to ground through the resistor. In order to prevent a vehicle from being jump started by using a second battery, the system includes a reset clock and associated delay that resets the decision to connect the alternator to ground at periodic intervals so as to repeatedly test for the presence of the second battery and cause the engine to stall after the second battery is disconnected. A driver entry detection portion of the system determines whether someone has entered the vehicle, and issues a chirp signal to notify the occupant that the system is armed. A state of charge algorithm is also provided to determine whether the battery voltage has reached a minimum state of charge for reliably starting the vehicle, and also disconnect the battery once the minimum level has been reached.

    摘要： A dual battery system includes a first battery and a second battery electrically connected in parallel to positive and negative terminals. The first battery has an open circuit voltage greater than that of the second battery so that, as current is drawn from both batteries, the amount of current drawn from each respective battery at a given voltage level varies depending on the magnitude of the current. The first battery preferably supplies most of the current at low to moderate current loads, whereas the second battery provides a greater portion of the total current at high current loads. According to one aspect of the invention, wherein the batteries are each lead-acid batteries, the desired difference in open circuit voltage is provided by using sulfuric acid electrolytes of different specific gravities in the two batteries. For this purpose the electrolyte specific gravity of the second battery is preferably at least 0.03 less than that of the first battery.
