Definitions
- the present invention belongs to the technical field of lead-acid batteries, and in particular, the present invention relates to an over-discharge performance evaluation of a lead-acid battery, and also relates to a capacity recovery method for a backward battery generated by over-discharge.
- the present invention is mainly directed to the problem of lack of a method for detecting the performance of lead-acid batteries in the industry, and proposes a method for evaluating the over-discharge performance of lead-acid storage batteries that is simple, easy to implement, and capable of quantitative analysis. This invention It also includes a capacity recovery method for the backward battery caused by abuse of overdischarge.
- the battery pack is tested for capacity when UA discharges to a termination voltage of 6 * 1.80V;
- the present invention has the following positive effects:
- the present invention is further explained by evaluating the abuse and overdischarge performance of lead-acid batteries with different design schemes.
- the A design scheme and the B design scheme were selected to prepare samples respectively.
- the sample specifications are 2V, 200AH lead-acid batteries, and the number is 9 each, and 6 of each scheme are used for the lead of the present invention. Acid battery over-discharge performance evaluation and capacity recovery method, the remaining 3 of each scheme are used for 100% DOD cycle life test.
- samples A and B are used to prepare samples, and the evaluation environment is 25 ° C ⁇ 2 ° C.
- the specific steps are as follows:
- the lead-acid battery sample was discharged at 20A until the termination voltage was 1.80V;
- the 100% DOD cycle life of the sample discharge depth of the A design scheme is 507 times, and the 100% DOD cycle life of the sample discharge depth of the B design scheme is 302 times.
- the A design sample is significantly better than the B design sample.
- the present invention adopts a quantitative evaluation method, which is simple and accurate, and has good timeliness, which is beneficial to further guide the design, thereby achieving the purpose of reducing the development cycle and cost.
- a user can recover the capacity of a backward battery generated by abuse of overdischarge, which is beneficial to timely and optimally adjusting the operating efficiency of the supporting battery pack.
