The invention provides a charging base indicating lamp circuit of a new energy automobile and a charging indicating device. The circuit comprises at least two indication branches, each indication branch comprises a light-emitting diode, a triode, a first current-limiting resistor and a second current-limiting resistor, an emitting electrode of the triode is connected with a preset power supply, and a base electrode of the triode is used for being connected with a battery management system of the new energy automobile through the first current-limiting resistor; the collector of the triode is connected with the anode of the light-emitting diode through the second current-limiting resistor, and the cathode of the light-emitting diode is grounded; the triode is a PNP triode; the battery management system is used for outputting different forms of low-level control signals to different indication branches when the new energy automobile is in different charging states; and the indication branch is used for emitting light in different forms through a light emitting diode when receiving the low-level control signals in different forms so as to form different indication signals for indicating different charging states of the new energy automobile. The short circuit risk can be greatly reduced.

    本申请提供一种新能源汽车的充电座指示灯电路以及充电指示装置。电路包括:至少两个指示支路,每一个指示支路中包括发光二极管、三极管、第一限流电阻和第二限流电阻,三极管的发射极与预设电源连接,三极管的基极用于通过第一限流电阻与新能源汽车的电池管理系统连接,三极管的集电极通过第二限流电阻与发光二极管的正极连接,发光二极管的负极接地;三极管为PNP三极管;电池管理系统用于在新能源汽车处于不同的充电状态时向不同的指示支路输出不同形式的低电平控制信号;指示支路用于在接收到不同形式的低电平控制信号时通过发光二极管以不同形式发光,以形成不同的指示信号,用于指示新能源汽车的不同充电状。本发明可以大大降低短路风险。
