An electric energy power system is connected with a first load (M1) and a second load (M2) and comprises a first power source (B1), a first power switch (KB1), a second power source (B2) and a second power switch (KB2). The positive electrode of the first power supply (B1) and the positive electrode of the second power supply (B2) are jointly connected to a first node (X1), and the first end of the first load (M1) and the first end of the second load (M2) are jointly connected to a second node (X2); the first node (X1) is connected with the second node (X2); the negative electrode of the first power supply (B1) is connected with the first end of the first battery switch (KB1), and the negative electrode of the second power supply (B2) is connected with the first end of the second battery switch (KB2); the second end of the first battery switch (KB1), the second end of the first load (M1), the second end of the second load (M2) and the second end of the second battery switch (KB2) are jointly connected to the power ground. According to the electric energy power system, front drive, rear drive, four-wheel drive and multiple working modes can be achieved only through the two switches, the control strategy is simple, the cost is low, and the reliability of the electric energy power system is improved. The invention further provides an automobile with the electric energy power system.
一种电能动力系统,与第一负载(M1)和第二负载(M2)连接,包括第一电源(B1),第一电源开关(KB1),第二电源(B2),第二电源开关(KB2);第一电源(B1)的正极和第二电源(B2)的正极共接于第一节点(X1),第一负载(M1)的第一端和第二负载(M2)的第一端共接于第二节点(X2);第一节点(X1)与第二节点(X2)连接;第一电源(B1)的负极与第一电池开关(KB1)的第一端连接,第二电源(B2)的负极与第二电池开关(KB2)的第一端连接;第一电池开关(KB1)的第二端,第一负载(M1)的第二端、第二负载(M2)的第二端以及第二电池开关(KB2)的第二端共接于电源地。该电能动力系统仅通过两个开关即可实现前驱、后驱以及四驱,以及多种工作模式,控制策略简单成本低,提高了电能动力系统的可靠性。还提供了一种具备该电能动力系统的汽车。
