The disclosure relates to a battery early warning method and device and a vehicle. The method comprises the steps: acquiring the current remaining capacity of a battery and the temperature of an environment where the battery is located; determining the discharge power of the battery according to the current remaining capacity of the battery and the temperature of the environment; acquiring the power demand of an electric vehicle under the current condition; determining whether a secondary early warning condition is met or not according to the discharge power of the battery and the current power demand of the electric vehicle;if so, carrying out warning prompting according to a preset mode; and if not, not carrying out warning prompting. According to the invention, accurate early warning prompt can be carried out according to the available electric quantity of the battery under different temperatures and different residual electric quantity percentages, adaptive early warning prompt canalso be carried out according to specific battery use working conditions, and the accuracy and the adaptability of a battery early warning strategy can be effectively improved.

    本公开涉及一种电池预警方法、装置及车辆,该方法通过获取电池当前的剩余电量和所处环境的温度;根据该电池当前的剩余电量和所处环境的温度确定该电池的放电功率;获取所述电动车辆当前状况下的功率需求;根据所述电池的放电功率与所述电动车辆当前的功率需求确定是否满足二级预警条件;当满足所述二级预警条件时,通过预设方式进行警告提示;当不满足所述二级预警条件时,不进行警告提示。本公开能够根据不同的温度和不同剩余电量百分数下电池的可用电量进行准确地预警提示,还能够根据具体的电池使用工况进行适应性的预警提示,能够有效提高电池预警策略的准确性和适应性。
