Description of the invention: [Technical field to which the invention belongs] The present invention is a "monitoring and early warning method and device for vehicle power supply (2)", which is a monitoring and early warning device set On the vehicle, in parallel with the battery to be tested and the starter motor, and using the starter motor as a load to form an outer loop sampling circuit, the sampling time is measured at 1 / t second intervals, and the sampling voltage value is measured instantaneously, and the interval is plotted The voltage curve, because when the motor is started by the motor, the voltage waveform measured at the parallel end will drop sharply and then rise again: at this time, a minimum point will be formed on the voltage curve. If 10 this voltage value and the system By comparing the set early warning values, you can determine whether the battery state can still continue to supply enough starting power for the starting motor to start the next π vehicle start and provide a timely warning display. [Previous technology] Press, when we use the vehicle, we need to supply enough starting 15 electric energy through the battery to start the motor and start the vehicle; however, practically, it is impossible to know in advance whether the battery still has sufficient Start the electric energy, so often only when the startup is not smooth, you will know that the battery power is insufficient, or although the motor can still be started successfully this time, the next time you restart, the battery is already worn out. 20 Furthermore, the life of a vehicle battery often depends on the ambient temperature, charging conditions, charging time, and load discharge. The influencing factors are extremely complex. For general batteries (such as NP-type batteries), their "discharge characteristics", " The relationship between "temperature characteristics" and "storage characteristics" is shown in Figures 12 to 14; due to 579342 amendment 351-2002TWP-5 / 28 ^-under the influence of many factors, if you want to avoid the embarrassment of temporarily unable to start the vehicle 'There is always a need to monitor the battery for a long time. [Summary of the Invention] 5 The main purpose of this month is to provide _ a kind of "monitoring and early warning method and device for vehicle power supply (2)" which can be installed on the vehicle for a long time.

The interval is M l / t seconds, and the value of the sampled money is measured instantaneously. For the electric service line, the voltage waveform measured at the parallel end will drop sharply and then rise again when the motor is used to start the vehicle, and a minimum point will be formed on the voltage curve. Therefore, the minimum voltage Compare the set early warning value, you can judge the battery status y and k for timely early warning display. 15 Another object of the present invention is to provide a "pre-monitoring method and device (1) for vehicle power supply", which is a monitoring and early warning device connected in parallel with the battery to be tested and the starter motor in a way The long-term monitoring of the state of the power supply can be constituted by the starter motor as a load—outer circuit type = circuit ^ When the starter motor starts the vehicle, the sampled voltage value is instantaneously measured in 1 / t seconds, and is determined by The monitoring and early warning device has a four-loop sampling circuit with the internal = load, and performs appropriate monitoring / invitation for each mode by appropriate time / knife configuration. Another purpose of the present invention is to provide "a method for monitoring and pre-police for vehicle power supply 5 20 579342 amended 351-2002TWP-6 / 28 method and device (2)", which is a monitoring and early warning device that starts with the voltage curve. Any point is used as a reference point, that is, the voltage value at any point within the preset sampling detection times within the entire range from the start point to the generator charging point, can be used as an important reference point for battery detection, and Can make a correct judgment basis of 5 battery status, and provide timely warning display.
