Comparing the Cold-Cranking Performance of Lead-Acid and Lithium Iron Phosphate Batteries at Temperatures below 0 °C

Six test cells, two lead–acid batteries (LABs), and four lithium iron phosphate (LFP) have been tested regarding their capacity at various temperatures (25 °C, 0 −18 °C) cold crank capability low (0 −10 −30 °C). During the test, LFP a higher voltage level all than LABs, which results in power energy output. Moreover, lower decline for decreasing temperature. Regarding cold-cranking definition, LABs passed but not °C. The °C At only of passed, while failed For comparability between technologies, it is suggested to redefine requirements standard terms or energy. With this redefinition, battery can generate comparable till
