Description of the Invention: [Technical Field] The present invention relates to a battery power residual estimation related technology, and more particularly to a battery power residual estimation method and system thereof. [Prior Art] Due to the global crisis of oil depletion, many oil-powered devices must seek to use other power sources. In terms of vehicles, each car manufacturer has been thinking about using electricity instead of oil as a source of power for vehicles. At present, some car manufacturers have introduced hybrid vehicles to reduce the amount of fuel used in vehicles. In addition, if the locomotive industry directly introduces the electric motor vehicle, the power is completely changed. In response to this wave trend, the future battery usage and output value will be greatly improved. How to effectively manage, repair and repair the battery will be a very important issue in the future. In the maintenance of the battery program, the battery charge is a very important judgment basis. However, the current accuracy of the battery residual is not awkward. The main reason is that the current residual estimation method directly uses different discharge currents. And the corresponding voltage change is used to calculate the residual amount of the battery. However, as shown in the second figure, the voltage drop corresponding to the maximum discharge current in the different discharge currents is very fast, because the slope of the voltage curve corresponding to each discharge current is different. However, the estimated battery residual amount error value is relatively large. In addition, the device for realizing the above-mentioned battery residual amount estimation method, as shown in the fifth figure, includes an external voltage and current detecting device (51) and a monitoring computer (52), and when used, the external voltage and current are detected. The device (51) is connected to the electrode of the battery to be tested (50) by wire, and is controlled by the 201128209 of the monitoring computer (52) to control the discharge current (4) of the battery to be tested (4), and according to the detection of the discharge current of each segment The voltage change of time is recorded by the monitoring computer (52) for calculation of the estimated residual amount of battery power at the back end. It can be seen from the above description that the current estimated battery residual capacity must still use the complicated wiring method to connect the battery to be tested to the external voltage and current detecting device in the operation of the device, and use the upper phase π pole n # n± clothing l K It is inconvenient and time-consuming to go to the field, which is not conducive to the application of a large number of batteries, and must find a better solution. SUMMARY OF THE INVENTION The present invention is directed to providing a method for predicting the remaining amount of a battery, which can accurately estimate the residual amount of the battery and improve the battery.

The wireless monitoring computer sends a detection command to the battery, and the embedded voltage and current detecting module is connected with the battery electrode according to the detecting command and switching different resistance value resistors to obtain different discharge current values; and the wireless monitoring computer is preset 201128209 There are various battery full voltage values, no voltage values and polynomial addition current equations; and a power supply is connected to the battery electrode and the wireless monitoring computer to control the output voltage of the wireless monitoring computer to the Battery electrode.

For example, if the battery is charged to a full voltage of 4.1 V, the battery voltage may drop to 3.9-4.0. Etc. Therefore, this step is to correct the error caused by the actual situation may be estimated in 201128209; discharge the battery to be tested (33); in this embodiment, a load is connected to the battery electrode to perform a fixed load discharge, And the load and the battery electrode are further connected through a switch to select a parallel connection with the resistance of the resistance of the ^f resistance, so that the battery is discharged at different constant currents (331) until the battery voltage reaches the no-electricity value. Therefore (332); therefore, in this step, the total discharge time and the voltage change value of each discharge current interval (333) can be recorded; the battery capacity (34) is calculated, and the initial voltage value is discharged, and the discharge is discharged. The time and the corrected capacitance are brought into the corresponding starting voltage equation 'calculate the current battery capacity; calculate the additive current value (35), select one more $ plus & current equation, and several discharge currents The value is brought into the polynomial addition current equation to calculate the additive current value; in this embodiment, the polynomial addition current equation $ is a fourth-order equation: y= 〇68χ4 + 3 588χ3_5 χ2 + 5·898χ- 〇·952, where y is the value of the additive current, χ is the value of the discharge current; and ββ# calculates the residual amount of the battery (36), and calculates the residual amount of the battery by the capacitance and the added current value. In the above step of calculating the battery capacity, in order to obtain more precise electrical settings, the improved storage method is used in conjunction with the open circuit voltage method to calculate the calculated parameter values, and can be applied to the battery of the non-full charge for capacitance.
