The invention discloses a battery cell balance control method and device and a vehicle. The method comprises the steps that the current temperature of a sampling plate is acquired; according to a comparison result of the current temperature and a pre-calibrated opening temperature, the number n of channels needing to be closed by the currently opened balancing channel is obtained; wherein n is greater than or equal to 0 and is an integer; and controlling the n currently opened balancing channels to be closed. By adopting the embodiment of the invention, the over-temperature of the sampling plate can be prevented, and the equalization efficiency is improved.

    本发明公开了一种电芯均衡控制方法、装置及车辆,所述方法包括:获取采样板的当前温度;根据所述当前温度与预先标定的开启温度的比较结果,获取当前开启的均衡通道所需关闭的通道数量n;其中,n≥0,n为整数;控制n个当前开启的均衡通道关闭。采用本发明实施例能够在防止采样板过温的同时,提高均衡效率。
