Description of the Invention (The present invention relates to a battery residual method that can significantly increase θ㈣, especially-a dry battery capacity prediction method. Π I uses a battery to provide temporary power or a continuous + / city Γ), which Temporary power comes from the battery pack = due to electricity: system (mains power is interrupted, Linri car expensive, shop 3 /, should therefore, when _ Μ power supply can be timely, the characteristics of the battery pack itself is = 2 urgent power supply characteristics It is extremely important. The key to the patent is because the battery is related to battery characteristics testing. 7) The patent case is a special-No. "Battery pack characteristics such as the invention patent right 0666." The method of continuous scanning and recording of battery packs and test items related to the characteristics of battery packs} method. Pressure, remaining capacity, etc., all respects, values, temperature values, terminal power are not easy to accurately pre-mix. 2: Gu: The estimation is extremely important. The relationship between the quantity and the discharge rate; ::: = is the typical battery capacity rn, 1… with the relationship between the non-discharge current and capacity. 'The higher the discharge current, the smaller the ampere-hour capacity. If the causal relationship is explored in ^, it can be seen that the amount of electricity discharged by the battery depends on the electrochemical effect of the effective substance on the inner plate and the electrolyte. At that time, the secret in the pores of the plate has become p and penetrates into the plate, and can only be carried out on the surface, so the capacity decreases sharply; otherwise, if the discharge rate is low, it is recommended to use capillary action to penetrate into the plate to generate sufficient chemistry. Function, so capacity can be increased. It can be seen that 'Battery Valley 1 has an absolute relative relationship with its discharge current. However, even if it is known that there is an inverse relationship between the remaining capacity of the battery and the discharge current, it is not possible to simply base this relationship on the discharge current to 530158. V. Description of the Invention (2) The remaining capacity of the battery is because each battery is the same and each The battery characteristics produced by the Wei family are also different, and Yiyi Ya does not use fixed test standards to estimate. It is difficult to use-species = :, the standard chemical potential of an acid battery is 2 volts, but because of the difference in the discharge current, it is different from different manufacturers ^ 9V 疋 Γ, such as umum • .. · ·· Temples are different. It can be seen from the following two examples that the different discharge currents and different termination voltages produce different densities. Example 1: When the termination voltage is 750V, 2V 2. Visit φ ιππλ for ^ 10〇〇ΑΗ Battery discharge duty, 10 hours to UOV, 100% capacity. Emperor == The termination voltage is L 832V, which is also 2V, and the private pool of Nei Lai discharges 250A, 3 hours to h 832v. The capacity is 100%. It can be seen from the above that even for batteries of the same specification, because Different discharge m is caused by different manufacturing methods and quality of f, which leads to the imperialism of the second emperor's pond and six densities. In addition, the temperature may also be measured, regardless of the shore, + m,-soap to push The definite factor known to estimate the remaining capacity of the battery, its accuracy is relatively low, it is conceivable to compete only. For example, the measurement of the remaining storage capacity of the invention patent right 1010931 battery = kind =: ί electricity rate, and then Multiply by the discharge current to find the remaining capacity. However, it obviously does not take into account the forefront factors, so the accuracy of its estimation is low, which effectively achieves the purpose of estimating the battery capacity. For some reason, it can be known from the above that, given the existing technology, it is still impossible to accurately estimate ------------- ¾ (Please read the precautions on the back before filling this page) Order: • Line · Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 530158 ΒΊ 5. Invention Description ($) The remaining capacity of the battery is obviously a big issue for the maintenance of the battery pack, so it needs to be further reviewed and a feasible solution is sought. Therefore, the main purpose of the present invention is to provide a test method that can accurately estimate the remaining capacity of a battery in a short time. Including the main technical measures adopted to achieve the foregoing purpose, the aforementioned method includes using the new battery to perform the discharge test, to obtain its standard discharge characteristics, and to establish a database based on it ...… random testing of the battery pack when the battery is discharged At that time, one of the electrical processes was used to quickly record its various characteristic data; and the I 1 I order was used to compare and analyze the measured value and the standard value stored in the database; the conversion obtained the remaining capacity of the tested battery. Because the description method uses a new battery to perform a discharge test according to different discharge currents and j voltage conditions to obtain a standard data line that establishes a database = Phase R specifications of the battery are discharged under the same conditions.
