中文摘要：

文章提出通过检测汽车起动用蓄电池开路电压、放电电流、终止电压及环境温度,综合测算蓄电池的电动势、内阻、冷起动电流及荷电容量;并通过量化蓄电池开路、单格短路、完全短路、硫化及性能退化等状态的特征,形成汽车起动用蓄电池的健康诊断方案;同时,结合实际需求,考虑汽车应急起动的安全性和便捷性,将健康诊断与应急点火功能集成,研制汽车起动蓄电池健康诊断及应急点火仪;试验表明该仪器具有良好的诊断和应急点火性能。

英文摘要：

In this paper , through comprehensive detection of the open circuit voltage , discharge current , final volt-age, and environment temperature of the automobile starter battery , the electromotive force, internal resistance, cold start current , and the state of charge are calculated .And by quantifying the characteristics of state when battery is at the condition of open circuit , single-cell short circuit , dead short , vulcanization and performance degradation , the au-tomobile starter batteries health diagnostic program is formed .Meanwhile , the health diagnosis and emergency ignition are functional integrated together considering the actual usage requirements , the safety and convenience of the car e-mergency starter , to develop , the automotive starter battery health diagnosis and emergency ignition device .The test shows that the device has good diagnosis and emergency ignition performance .
