| Abstract: | The capacity experiments of 12 V/55 Ah(C/20) power valve regulated lead-acid(VRLA)battery and 3.2 V/11 Ah power LiFePO_4 Li-ion battery were carried out.The relations between their capacity characteristics and discharge current,discharge start voltage,temperature rise and the ambient temperature were investigated.The capacity of LiFePO_4 Li-ion battery had only about 10% decrease at 2 C current discharge while the VRLA battery had near 50% decrease at 1.5 C. |
