EV Charger Schematic Review
K_CHG / K_DIS 硬件互锁后重新 ERC。K_CHG / K_DIS 线圈驱动相关连接:
24V_RELAY_AFTER_ESTOP 供电;K_CHG_COIL_LOW 和 K_DIS_COIL_LOW 分别由 Q1/Q2 低边 NMOS 驱动;K_CHG / K_DIS 硬件互锁,建议用对方的 NC 辅助触点串入本接触器线圈供电路径:
24V_RELAY_AFTER_ESTOP -> K_DIS_NC_INTERLOCK -> K_CHG coil24V_RELAY_AFTER_ESTOP -> K_CHG_NC_INTERLOCK -> K_DIS coilCP_GENERATION_AND_MONITORCC_PP_RC_R4_AND_DISCHARGE_IDENTIFICATIONCHARGE_AND_DISCHARGE_CONTACTOR_CONTROLAC_MAIN_PATH_AND_BIDIRECTIONAL_MEASUREMENTPOWER_MCU_COMMUNICATIONPILOT_OUT, with CP/CC/PP interpretation notes updated.R1_CP was defined as the mandatory 1.000 kΩ, 0.1%, 0.5 W GB/T control-guide equivalent series resistor, with CP monitoring on the CP_OUT side.K_CHG/K_DIS hardware interlock was started conceptually but not completed due to ACU limits.Waiting for input
