The standby pen source is generally composed of a secondary battery and its power conversion circuit. When the utility power is normally supplied to the instrument, the battery is also charged; when the utility power is interrupted, the battery discharges power to supply power to the instrument. This secondary battery gradually reduces the storage capacity of the battery due to repeated charge and discharge cycles, which is called aging. When the degree of aging is reached, that is, the storage capacity of the battery is only the successor of the original new battery, the number of times of charge and discharge is called the battery life cycle. In order to maintain the reliability of the equipment, it is necessary to replace the battery with a significant aging. If the secondary battery is completely aging, it will warn that the replacement is too slow, so the measurement of the aging of the secondary battery is very important for predictive maintenance. The conventional method for measuring the degree of battery aging is mainly to use the C偷Ulum-counting method, that is, the current integration method to know the aging degree of the current battery. 1267647 where α is the rated value of the battery when it leaves the factory. capacity. The biggest disadvantage of this prior art is that it takes up to a battery to complete the full charge, which is generally more than one hour, which is very inconvenient to use. China's invention patent 348 325 also discloses a situation in which the average temperature rise rate of the battery is used to touch the battery system, but it still has the disadvantage of not being able to measure the aging degree of the battery in a short period of time. To this end, the present patent discloses an apparatus and method for measuring the degree of aging. The technical feature is that the battery is aged according to the estimated storage capacity of the voltage ladder of the battery. The amount of aging of the new battery disclosed in this patent can be measured within a minute, and the degree of aging of the battery can be measured within one minute. Compared with the conventional technology, there is a significant improvement in the money of the vehicle. Jt [Summary] The problem to be solved ·· or the purpose of the purpose of the solution ^ know the electric riding and cutting metric - the method in the short-term _ quantity _ battery aging degree problem 2 · 0_ the technical means and effects: 1267647 Using a certain current to charge, the battery's voltage gradient is used to estimate the battery's storage valley 2 . Then, according to the %, the degree of aging of the battery is obtained. The new battery aging measuring device and method of the patent can measure the aging degree of the battery within one minute in a short time. Compared with the conventional technique, the battery aging measuring device and method disclosed in the present invention have a significant improvement in the measurement time. [Embodiment] As shown in Fig. 1, a block diagram of a battery aging degree measuring device disclosed in the present invention includes a display device, a control device 30', and a current generating device 40. - Battery 50, - Voltage measuring device 60 and - Timing. The wheel unit 1() is used to input the rated capacity β of the battery at the time of shipment. The display device 2A is used to measure the age of the battery to be measured. The constant generating device 4 is used to receive the command of the control device 3G. (4) generating a certain current to charge the battery 50. The voltage is used to measure the voltage of the battery, and the battery voltage value is sent to the control unit. Set to 30. The timing device 7G is used for the timer-solid time. During this fixed time, the battery % is regulated by the constant current generating device 40 at a constant current. In addition to the calculation of the battery aging process of 1267647 degrees, the control system 4 30 also coordinates the actions of the input device 10, the display device 20, the constant current generating device 40 and the reliance on the position 60, and measures the aging degree of the wire battery. Features. When the working flow chart of the entire system is started as shown in Fig. 2, the input device 10 knows the rated capacity β of the battery when it leaves the factory. Then 'measure the battery _ slave current charging _ degrees, and this cake ladder wire battery can now store the capacity (four). Finally, the degree of the battery surface is calculated according to the battery aging index D=¥_%, and the battery aging index is displayed on the display loading. Read the Wei Wei _ Measure the procedure as shown in Figure 3. The measurement device 6 〇 measures the voltage across the battery ^, denoted as Vl. After the amount is completed, the control device 30 commands the generating device 40 to send a certain current to charge the battery 50, and simultaneously sets 30 and causes the timing device 7 to start timing for a fixed time τ. After ^Nissan 2, the system measures the voltage across the battery 5 ,, which is recorded as %. Then, the voltage of the battery 50 in this fixed time τ is measured, or 1 to estimate or check the meter to obtain the capacity that the battery 5 can now store.

Wherein, the battery casing is printed or affixed with a barcode, the barcode contains the amount ρ, the message of the battery at the factory, and the microprocessor uses 8-bit 8-inch 51, digital/analog converter adopts DAC0832 The analog/digital converter uses an ADC 〇8〇4, and the subtractor is composed of an operational amplifier LM124 and several resistors. The entire workflow is as shown in Fig. 5, and is described as follows. First, the barcode reader 81a drinks the battery bar code to know the rated capacity 2 of the battery 5 at the time of shipment. Next, the subtraction state 86 measures the voltage across the battery 50 and transmits it to the analog/digital conversion H 87 for use in deriving the voltage value of the battery 5Q. The microprocessor 83 records the voltage digital value and sends the optimal test current amount 〇·% of the charging current of the residual digital/class rotation correction 84 into an analog signal for controlling the controllable current source 85 to generate a 〇· % constant current to battery = charge.
