Abstract
The invention discloses a detection method of lead-acid accumulator capacity, which comprises the following steps in order: A, testing a to-be-tested accumulator by using a short-circuit tester to eliminate a short-circuit battery; B, performing constant-current discharging on the battery for 2 hours by using discharging function of a detector, standing for 30 seconds, measuring a recovery voltage V of the battery; C, computing the measured battery voltage V to obtain a battery dischargeable capacity by using the formula as follows: C=a(V/n-0.85)+b, wherein n is the number of a monomer battery, a and b are the empirical constant. The detection method has the advantages that the battery can be directly discharged without charging, the battery dischargeable capacity can be directly computed, the battery health status can be estimated, the detection method is accurate and rapid, and the usage rate of a discharge device is high.
Description
Technical field
The present invention relates to a kind of capacity of lead acid battery detection method.
Background technology
Along with the rise of Moped Scooter in China, lead-acid accumulator is used more and more, as the major impetus source of Moped Scooter.The lead-acid accumulator that is applied to Moped Scooter is made into one group of series connection with 3 or 4 and uses based on 12V12Ah, mostly is serviceable life about 1 year.Lead-acid accumulator occur to safeguard or trouble shooting procedure in, the attendant with the charger full charge again with constant-current discharge to final voltage, can emit electric weight as the foundation of judging the battery quality with battery.Existing capacity of lead acid battery detection method need be given the battery full charge, need about 10 hours time, add that discharge needs 1-2 hour time, sense cycle is long, battery charge and discharge need the higher equipment of precision to do guarantee in addition, and this has brought no small difficulty also for dealer and after sale service personnel battery maintenance.The factor of examined time and checkout equipment restriction is particularly outstanding when the attendant makes house calls to the user after sale.
Summary of the invention
The object of the present invention is to provide a kind of capacity of lead acid battery detection method, can effectively solve the problem that prior art detects capacity of lead acid battery time length and can't detect cell health state.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of capacity of lead acid battery detection method may further comprise the steps successively:
A. adopt short circuit tester to test the unshorting battery on accumulator to be measured;
B. utilize the detector discharging function that battery is carried out the steady current discharge of 1-3 hour 10A, measure battery rise voltage V after second at interval 20-40;
C. with the battery rise voltage V that records, utilize C=a (V/n-0.85)+b to calculate the capacity that battery can be emitted electricity, wherein n is the cell number, and a, b are empirical constant.
Preferably, the value of a among the described step C is-51.28, and the value of b is 70.10.
Compared with prior art, advantage of the present invention is: need not charge and directly battery be discharged, save the charging operations time, not need charging equipment; Directly discharge under the insufficient situation of battery, emitted capacity or be called the battery discharge capacity but can calculate battery, detection method is accurately quick, discharge equipment utilization factor height.This kind detection method is fast and convenient, and is workable, can satisfy the requirement of lead-acid accumulator attendant battery detecting method, but and can utilize the method counting cell discharge capacity, the i.e. health status of battery.
