摘　　要：通过试验研究了全海深深潜器所用磷酸铁锂离子电池在常压、20℃,常压、3℃,以及高压100MPa、20℃环境下的电气特性,评价了最大放电深度、内阻、开路电压随温度和压力变化的情况.结果表明:在常压、3℃条件下锂离子电池最大放电深度的衰减较大,欧姆内阻与极化内阻的增幅较大,开路电压略有降低;与常压、20℃相比,在高压100MPa、20℃下,锂离子电池最大放电深度的衰减较大,欧姆内阻略有增加,而开路电压略有降低.A series of lithium iron phosphate batteries characteristics test were taken to analyzing the relationship between batteries electrical characteristics and the temperature or pressure.The relationship between maximum depth of discharge(DOD),internal resistance and open circuit voltage with temperature and pressure was studied.The results show that under atmospheric pressure and 3℃,the maximum DOD of the battery is greatly attenuated.The ohmic internal resistance and the polarization internal resistance increase significantly,and the open circuit voltage is slightly reduced.Compared with atmospheric pressure and 20℃,at the high pressure of 100 MPa and 20℃,the maximum discharge depth of the battery is greatly attenuated,the ohmic internal resistance is slightly increased,and the open circuit voltage is slightly lowered.
