Effect of temperature on the charging and discharging cycle performance of lithium iron phosphate batteries for electric vehicles
Lithium iron phosphate batteries are the core hardware of electric vehicles,and their performance directly determines the operational efficiency of electric vehicles.Therefore,a study on the effect of temperature on the char ging and discharging cycle performance of lithium iron phosphate batteries for electric vehicles is proposed.Select appropriate experimental materials and equipment,prepare lithium iron phosphate batteries,develop temperature control programs and charging and discharging cycle testing plans,determine the charging and discharging cycle per-formance indicators of lithium iron phosphate batteries,conduct charging and discharging cycle performance experi-ments on lithium iron phosphate batteries for electric vehicles,and record experimental data.Through the analysis of the experimental results,it can be known that the optimal working temperature of lithium iron phosphate battery is 0-40 ℃,and the battery capacity,battery internal resistance,battery energy density,battery power density,battery cycle life and battery electrolyte performance are optimal in this temperature range.
