| 摘要： | 本发明公开了一种电动汽车安全充电的保护方法，具体为：A)过电流保护：根据过电流状态的持续时间来决定是否保护；B)过压和欠压保护：根据过压或欠压状态持续的时间来决定是否保护；C)过温度保护：根据供电端插合时的温升状态，通过交流充电装置调整与车辆通讯数据，从而间接调整充电电流的大小；D)未接地和火零线相保护：交流充电装置上电后，实时侦测供电接线状态是否正确，包括检测是否可靠接地、供电端的火线和零线是否错相，并根据实际应用需求对充电电源进行通断控制；E)漏电保护：交流充电装置上电后，实时侦测整个交流供电过程中火零线与地线之间的泄漏电流大小，当泄漏电流超过设定阀值，则切断充电供电。确保安全充电。 | ||
| 摘要(英文)： | The invention discloses an electric automobile safety charging protection method, in particular to : A) over-current protection : according to the current state to determine whether the duration of the protection; B) an overvoltage and undervoltage protection : according to the over-voltage or under-voltage state to determine whether the duration of the protection; C) over-temperature protection : according to the temperature rise of the power supply terminal is inserted into the state, through the AC charging device adjusts the communication data of the vehicle, thereby to indirectly adjust the magnitude of the charging current; D) is not grounded and fire protection zero : AC charging device after the power up, real-time detect power supply wiring state is correct, includes detecting whether the reliable grounding, whether live wire and zero line of the supply phase, and according to the actual application needs of the on-off control of the charging power; E) leakage protection : AC charging device after the power up, real-time detect the entire AC power supply and ground wire fire zero curve in the course of the leakage current between the size, when the leakage current exceeds the set threshold, then the cut off the charging power supply. Ensure the safe charging. | ||
