The invention discloses a safety protection method of a relay and an electric vehicle. The safety protection method of the relay comprises the steps: acquiring the working temperature and the workinghumidity of the relay; when the working temperature of the relay is higher than a first preset temperature, or when the working humidity of the relay is higher than a first preset humidity, sending out the prompt information, and limiting the relay to be closed; when the temperature of the relay is greater than a second preset temperature, or when the humidity of the relay is greater than a secondpreset humidity, sending out warning information, and disconnecting the relay or limiting the relay to be closed. According to the safety protection method, the relay can be well prevented from beingdamaged, the failure probability of the relay is reduced, the service life of the relay is prolonged, and therefore the safety of a circuit system is improved.
本发明公开了一种继电器的安全保护方法及电动车辆,该继电器的安全保护方法包括:获取继电器的工作温度和工作湿度;当所述继电器的工作温度大于第一预设温度时,或,当所述继电器的工作湿度大于第一预设湿度时,发出提示信息,并限制所述继电器闭合;当所述继电器的温度大于第二预设温度时,或,当所述继电器的湿度大于第二预设湿度时,发出警告信息,并断开所述继电器或者限制所述继电器闭合。该安全保护方法能较好地预防继电器损坏,降低了继电器失效的几率,延长了继电器的使用寿命,从而提升电路系统的安全性。
