    • 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.
    • 一种车辆防盗系统,其通过断开车辆电池并通过电阻器将车辆电气系统电压排到地面,在发动机运行之后检测到未经授权的车辆启动时禁用车辆发动机。 当系统布防时,它监视发动机是否正在运行,并且最近通过检测振动,VES电压的波动和实际的VES电压来启动。 该系统包括具有电池内部接触的电动机械开关,车辆电气系统,标准电池外部端子,触点和断开触点。 当开关连接到电池触点时,车载电池连接在电路中。 当开关连接到车载电气系统触点时,系统通过电阻连接到地,电池与电路断开。 当开关连接到断开触点时,电池断开,车辆电气系统未连接到地面。 当开关未通电时,它或者连接到电池触点或断开触点。 当开关通电时,开关将切换到车辆电气系统触点,然后当它断电时,它将切换到相对的电池触点或断开触点。 该系统包括逻辑,以便如果发动机正在运行并且当它被布防时最近已启动时,系统将使开关通电以将其从电池触点断开,并将其连接到车辆电气系统触点一段预定的时间以排出 电气系统电压接地。

    • 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.
    • 一种车辆防盗系统,其通过断开车辆电池并且通过电阻器将交流发电机电压排到地面,在发动机运行之后检测到未经授权的车辆启动时禁用车辆发动机。 支架发射机发射由与防盗系统相关联的接收机接收的编码频率信号以使系统臂。 当系统布防时,它监视发动机是否正在运行,并且最近开始使用振动检测,电池电压的电压波动和实际电池电压的组合。 如果系统确定发动机正在运行并且最近已经启动,系统将发出第一个命令,打开一个继电器开关以断开电池,另一个命令关闭一个开关,通过电阻将交流发电机连接到地。 为了防止车辆通过使用第二电池跳转开始,系统包括复位时钟和相关联的延迟,其重置以周期性间隔将交流发电机连接到地的决定,以便重复测试第二电池的存在 并在第二个电池断开后引起发动机停转。 系统的驾驶员进入检测部分确定有人是否已经进入车辆,并且发出啁啾信号以通知乘客系统被布防。 还提供充电算法以确定电池电压是否已经达到用于可靠启动车辆的最小充电状态,并且一旦达到最小电平,也断开电池。

    • A 24/12 volt battery power supply for a vehicle includes two 12 volt batteries connected in series, and having first and second 24 volt terminals to the opposite ends of the batteries and a 12 volt terminal to the center common connection of the batteries. The 12 volt loads are divided into equal right and left side vehicle loads and the right side is connected across one battery and the left side is connected across the second battery. A three phase wye-connected alternator has the winding connected to a full wave three phase rectifier, the D.C. output of which is connected to the 24 volt terminals. The center common connection of the winding is connected directly to the 12 volt terminal. The system operates with balanced currents and charges on the two 12 volt batteries so long as the 12 volt loads remain balanced. Control loads are selectively connected to the right and left side loads if a 12 volt load is lost, disconnected or otherwise changes to maintain the balanced system but only if the imbalance due to lost loads is large. In another embodiment, the full wave rectifiers are connected to conduct the opposite half cycles of the alternator output. The controlled rectifiers for each half cycle have the gates connected to a common gate source, and a logic circuit monitors the voltage of each battery and actuates one or the other of the rectifier groups to prevent one battery segment from significantly varying in voltage with respect to the other.

    • A multiple battery system and method for starting internal combustion engines, such as on a boat or vehicle, and for powering auxiliary functions that operate primarily when the engine is not running is disclosed. A first battery is used for starting the engine. A second battery is used to power the auxiliary features associated with the boat or vehicle primarily when the engine is not running. The first battery, referred to as the starter battery, is a high output battery that produces high bursts of energy for limited amounts of time. The second battery, referred to as the auxiliary battery, has a low power output over a fairly long period of time, is capable of being completely drained without harming the battery, and is capable of being fully recharged. The starter battery and the auxiliary battery are connected by a circuit that has an on/off switch controlled by an electronics control module. The auxiliary battery is always on line in the circuit. The electronics control module monitors the circuit to detect certain parameters, such as a start engine event. When a start engine event is detected, the electronics control module connects the starter battery to the circuit with the switch. When the start event is over, the electronics control module disconnects the starter battery from the circuit with the switch. Thus, the electronics control module prevents the starter battery from being drained when power is being drawn from the auxiliary battery during non-start events.
    • 公开了一种用于启动诸如船上或车辆的内燃机以及用于对发动机未运行时主要工作的辅助功能供电的多电池系统和方法。 第一个电池用于起动发动机。 第二个电池主要用于在发动机不运行时为与船只或车辆相关联的辅助特征提供动力。 被称为起动电池的第一个电池是高输出电池,在有限的时间内产生高能量的电力。 被称为辅助电池的第二电池在相当长的时间段内具有低功率输出,能够在不损坏电池的情况下完全耗尽,并且能够被充分充电。 起动电池和辅助电池由具有由电子控制模块控制的开/关开关的电路连接。 辅助电池总是在线路上。 电子控制模块监视电路以检测某些参数,例如启动引擎事件。 当检测到启动发动机事件时,电子控制模块将起动电池与开关连接到电路。 当启动事件结束时,电子控制模块将开关电池从开关断开。 因此,电子控制模块防止在非启动事件期间从辅助电池抽出电源时起动电池被排出。
