摘要
采用瞬时放电法测量电池内阻并间接得到剩余容量。选择4只性能差别较大的铅酸电池，通过横向和纵向对比内阻与容量的关系，验证瞬时放电法的可行性。通过1只全新电池的测试，发现当容量为80％。100％时，内阻为29．56～42．83mΩ，表明剩余容量测试的分辨率能达到5Ah以内。
Resistance of the battery was measured by instantaneous discharge method and the residual capacity was obtained indirectly. Four lead-acid batter/es with great difference of performance were chosen, the feasibility of instantaneous discharge method was verified by horizontal and vertical comparison of the relation between internal resistance and capacity. Through the test of a brand new battery,it was found that the internal resistance was 29.56 - 42.83 mΩ when the capacity was 80% - 100% ,it showed that the resolution of residual capacity test was less then 5Ah.
