In view of the serious environmental pollution of lead-acid battery of Starting Power for New Energy Automobile, a 25.6 V/65 A•h lithium iron phosphate battery pack was assembled with 32650 type of cylindrical lithium iron phosphate cell to replace the lead-acid battery for starting power for new energy automobile. The room temperature and low-temperature starting capability, rate capability and low-temperature discharge performance were investigated. The battery pack provided a capacity of 67.03 A•h at 0.33 C and retained 98.24% capacity at 3 C. The battery pack obtained 84.7% of capacity at −30oC. The voltage of every single battery was higher than the discharge protection voltage when the battery pack was discharged at 600 A under 25oC and −20oC, respectively. The battery pack retained 99.37% of capacity after storage at 25oC for 28 days. All these data can meet the requirements of the starting power, indicating that the lithium iron phosphate battery pack can replace the lead-acid battery as starting power for new energy automobile.
