The present disclosure relates to a dual energy storage system (13) comprising: a lithium ion battery (22) electrically coupled in parallel with a lead acid battery (20), where the lithium ion battery (22) and the lead acid battery (20) are electrically coupled to a vehicle bus (19), where a lithium ion battery open circuit voltage (OCV) partially matches the lead acid battery OCV, where the lithium ion battery (22) and the lead acid battery (20) are electrically coupled to the vehicle bus (19). Such that the lead acid battery OCV at a 100% state of charge (SOC) of the lead acid battery is approximately equal to the lithium ion battery OCV at a 50% SOC of the lithium ion battery. 本公开涉及一种双能量存储系统(13)，包括：与铅酸电池(20)并联地电耦接的锂离子电池(22)，其中锂离子电池(22)和铅酸电池(20)电耦接到车辆总线(19)，其中锂离子电池开路电压(OCV)部分地匹配铅酸电池OCV，以使得在铅酸电池100％荷电状态(SOC)下铅酸电池OCV约等于在锂离子电池50％SOC下锂离子电池OCV。
