该电路通过使用传感器(如电流互感器、分压器)和比较器来测量实时电气值(电流、电压、绝缘电阻)。这些测量值与电路中逻辑(通常通过微控制器或专用保护集成电路实现)预设的安全阈值进行比较。如果任何参数超出其安全限值,保护逻辑将激活继电器、MOSFET或其他开关器件以中断电流,并可能向控制器的主处理器发送故障信号。

不是客户评论,也不是实时热度。以下维度用于前期 RFQ 准备和供应商评估。
这些分值是采购评估维度示例,不代表真实客户评分、具体国家买家反馈或实时询盘。
The circuit continuously monitors electrical parameters during EV charging operations, detecting faults like ground faults, overcurrent, or voltage irregularities, and triggers protective actions to prevent hazards.
The Ground Fault Circuit Interrupter (GFCI) detection circuit identifies leakage currents that could indicate electrical faults, immediately disconnecting power through relays or solid-state switches to prevent electric shock or fire risks.
Key components include high-precision current/voltage sensors for accurate monitoring, robust protection logic ICs or microcontrollers for decision-making, and reliable isolation relays or solid-state switches for immediate fault response.
