The invention discloses a charging and discharging identification module, a charging pile, a charging device and a discharging device. The charging and discharging identification module comprises a first resistor module, a first detection end and a signal processing module. The first end of the first resistor module is connected with the signal processing module, and the second end is grounded; the first detection end is connected with the first end of the first resistor module and the signal processing module and used for being connected with auxiliary detection resistor modules with different resistance values, and when the first plug is connected into the charging device or the discharging device, the first resistor module is connected with the auxiliary detection resistor modules in parallel; the signal processing module is used for outputting a charging indication signal or a discharging indication signal to the vehicle through the second plug according to the parallel signal, and judging whether the first plug is a charging device or a discharging device by identifying a resistance value after the first resistance module and the auxiliary detection resistance module are connected in parallel; the corresponding charging indication signal or discharging indication signal is output to the vehicle, the module complexity is reduced, the cost is reduced, and the charging and discharging identification reliability is improved.

    本发明公开了一种充放电识别模块、充电桩、充电装置及放电装置,充放电识别模块包括第一电阻模块、第一检测端和信号处理模块;第一电阻模块的第一端与信号处理模块相连,第二端接地;第一检测端与第一电阻模块的第一端和信号处理模块相连,用于连接不同电阻值的辅助检测电阻模块,在第一插头接入充电装置或放电装置时,第一电阻模块与辅助检测电阻模块并联;信号处理模块,根据并联信号,通过第二插头输出充电指示信号或放电指示信号至车辆,通过识别第一电阻模块与辅助检测电阻模块并联后的电阻值,判断接入第一插头为充电装置或放电装置,输出对应的充电指示信号或放电指示信号至车辆,降低模块复杂度,减少成本,提高充放电识别可靠性。
