所述第三连接关系调整接口S3还通过第六继电器R6连接于所述第五连接关系调整接口S5。The third connection relationship adjustment interface S3 is also connected to the fifth connection relationship adjustment interface S5 through the sixth relay R6.
另外，本实用新型对继电器进行互锁保护，即保证在某一继电器闭合后，不可同时让可能导致待测电池系统短路的继电器处于闭合状态。In addition, the utility model interlocks and protects the relay, that is, after a certain relay is closed, the relay that may cause the short circuit of the battery system to be tested cannot be simultaneously closed.
进一步来说，当电器安规测试仪11的正输出端连接待测电池系统15的壳体时，由于目前绝大部分电器安规测试仪的负输出端和输入地端为共地设计，当待测电池系统15的壳体存在接地情况时，电器安规测试仪11的正负输出端之间将通过大地产生过大的漏电流，从而出现失效误报。因此，在本实用新型实施例的另一种可能的实现方式中，所述系统还设置有第一隔离变压器18；如图3所示，所述第一隔离变压器18设置于所述电器安规分析仪11和所述第一外部供电设备16之间。Further, when the positive output end of the electrical safety tester 11 is connected to the casing of the battery system 15 to be tested, since the negative output end and the input ground end of most electrical safety testers are designed in common, when When the housing of the battery system 15 to be tested is grounded, an excessive leakage current will be generated between the positive and negative output terminals of the electrical safety tester 11 through the ground, thereby causing a false alarm. Therefore, in another possible implementation manner of the embodiment of the present invention, the system is further provided with a first isolation transformer 18; as shown in FIG. 3, the first isolation transformer 18 is disposed on the electrical safety device. Between the analyzer 11 and the first external power supply device 16.
接入第一隔离变压器18后，电器安规测试仪11的负输出端不再接地，则不会出现此种失效误报。After the first isolation transformer 18 is connected, the negative output end of the electrical safety tester 11 is no longer grounded, and such failure false alarm does not occur.
当待测电池系统15进行上电测试时，如壳体存在接地情况，则电器安规分析仪11的电压会通过壳体，通过大地等电位到达直流电源13的输入地端，再经由直流电源13的负输出端，最终到BMS的
负供电端。则此时，电压将加在直流电源输入输出间和BMS系统电压采样系统和供电系统间，可能导致直流电源和BMS元件的损坏。为解决该问题，在本实用新型实施例的另一种可能的实现方式中，在该系统中还需要设置第二隔离变压器19；所述第二隔离变压器19设置于所述直流电源13和所述第二外部供电设备17之间。When the battery system 15 to be tested performs the power-on test, if the housing is grounded, the voltage of the electrical safety analyzer 11 passes through the housing, reaches the input end of the DC power source 13 through the earth potential, and then passes through the DC power source. The negative output of 13 and finally to the BMS
Negative power supply terminal. At this time, the voltage will be added between the DC power input and output and the BMS system voltage sampling system and the power supply system, which may cause damage to the DC power supply and BMS components. In order to solve the problem, in another possible implementation manner of the embodiment of the present invention, a second isolation transformer 19 is further disposed in the system; the second isolation transformer 19 is disposed on the DC power supply 13 and the Between the second external power supply devices 17.
