The invention provides a new energy automobile storage battery protection control method, system and device and a medium. The method comprises the steps that the voltage and temperature of a storage battery in a new energy automobile are obtained; comparing the voltage and the temperature with a preset voltage and a preset temperature, wherein the preset temperature comprises a first preset voltage and a second preset voltage; if the voltage is smaller than or equal to the first preset voltage, determining that the storage battery is under-voltage, and charging the storage battery until the voltage reaches the first preset voltage; if the voltage is larger than the second preset voltage, it is determined that the storage battery is in overvoltage, charging of the storage battery is forbidden, and discharging of the storage battery is allowed; and if the temperature is greater than the preset temperature and the duration is greater than the first preset time, determining that the storage battery is in thermal runaway, and performing fault diagnosis in response to thermal runaway so as to deal with a thermal runaway fault, thereby avoiding negative effects caused by overvoltage, undervoltage and thermal runaway of the storage battery, ensuring that the storage battery does not lack of electricity, and improving the reliability of the storage battery. And the safety and the service life of the storage battery are improved.

    本申请提供一种新能源汽车蓄电池保护控制方法、系统、设备及介质,该方法包括:获取新能源汽车中蓄电池的电压与温度;将电压、温度与预设电压、预设温度进行比较,预设温度包括第一预设电压与第二预设电压;若电压小于等于第一预设电压,则确定蓄电池欠压,对蓄电池进行充电,直至电压达到第一预设电压为止;若电压大于第二预设电压,则确定蓄电池过压,禁止对蓄电池进行充电,并允许蓄电池放电;若温度大于预设温度且持续时间也大于第一预设时间,则确定蓄电池热失控,响应于热失控进行故障诊断,以处理热失控故障,本申请避免了蓄电池电压过压、电压欠压以及热失控所引发的负面影响,确保了蓄电池不亏电,提高了蓄电池的安全性与使用寿命。
