Battery rescue start reset device

A reset device, especially a battery rescue start reset device that uses a reset connection line to reset an electronic switch to avoid malfunction caused by improper operation.

A vehicle or a locomotive and the like are provided with a battery as a power supply source for the steam locomotive. When the user drives the steam locomotive, the engine of the automobile can be operated to charge the battery, and when the automobile is charged, When power is consumed, for example, a starter motor, a headlight, an in-vehicle sound, an air-conditioning system, and the like are outputted by the battery.

If the driver forgets to turn off the headlights, nightlights or related electrical appliances when the driver gets off the bus, there is a possibility that the battery will not be charged, but the battery will continue to discharge, causing the battery to run out of power and further causing the vehicle to fail to start. The problem. There will be drivers who will look for batteries from other vehicles to start their own vehicles. However, it is necessary to have two power cords that can be connected to both sides, and must also be connected to the correct battery polarity. If the connection is wrong, then there is The danger of short circuit.

Some operators have developed an emergency vehicle rescue device. The vehicle rescue device has a control circuit for automatically distinguishing the polarity of the vehicle battery. When the user's vehicle battery is over-discharged and cannot be started, the emergency vehicle can be used. The rescuer is electrically connected to the positive terminal and the negative terminal of the vehicle battery, and the emergency vehicle rescuer provides sufficient power for the vehicle to start the vehicle.

However, when the above-mentioned emergency vehicle rescue device is used, the following problems and defects are still to be improved: since the relay has a characteristic of withstanding high current, the control circuit of the emergency vehicle rescuer uses the relay as the emergency vehicle rescuer. A switch that supplies power to the vehicle battery. When the user connects the positive connection line and the negative connection line of the emergency vehicle rescue device to the positive terminal and the negative terminal of the vehicle battery, respectively, the relay is in an on state to supply power to the vehicle battery. However, when the user removes the positive connection line and the negative connection line of the emergency vehicle rescue device from the positive end and the negative end of the vehicle battery, the relay maintains an on state.

However, when the relay is kept in the on state and cannot be reset, if the user connects the positive connection line and the negative connection line of the emergency vehicle rescue device to the positive terminal and the negative terminal of the vehicle battery, respectively, since the relay maintains conduction. In the state, the relay may generate a spark due to the passage of a large current, and the life of the relay may also decrease. Moreover, if the user connects the positive connection line and the negative connection line of the emergency vehicle rescue device to the negative terminal and the positive terminal of the vehicle battery, respectively, this is an erroneous connection, and the relay maintains the conduction state. A short circuit hazard occurs when the wrong vehicle battery is powered.

In order to solve the above problem, various operators have to think about how to reset the relay to a non-conducting state when the user removes the positive connection line and the negative connection line of the emergency vehicle rescue device from the positive end and the negative end of the vehicle battery. . In the prior art, hardware reset and software reset are mainly used. The hardware reset mode mainly includes a manual switch in the emergency vehicle rescue device, and the relay can be reset when the user only switches the manual switch. However, this method can solve the relay reset problem, but it is not intuitive and user-friendly. The software reset mode is mainly programmed with an automatic program in the wafer microprocessor of the control circuit, and the relay is programmed to reset every few seconds (for example, two seconds). However, although this method automatically solves the relay reset problem, the user does not have to manually operate, but when the user connects the positive connection line of the emergency vehicle rescue device and the negative connection line to the vehicle battery within two seconds, the same will be The above problems have occurred.
