The invention relates to a power battery cell arrangement method of an electric vehicle, and a battery pack. In the battery pack of the electric vehicle, power battery cells are obliquely fixed in a battery pack shell instead of the bottom surface of the battery pack shell and/or the side surface of the battery pack shell. According to the battery pack, as the power battery cells are obliquely fixed in the battery pack shell, damage to the power battery cells in a bottom-supporting accident can be reduced under the condition of not increasing the cost and the mass of the whole vehicle, and the safety and the reliability of the battery pack in the bottom-supporting accident are improved.
本发明涉及一种电动车的动力电池单体排布方法及电池包。在该电动车的电池包中,相较于电池包壳体底面和/或电池包壳体侧面,动力电池单体倾斜固定在电池包壳体内。通过将动力电池单体倾斜固定在电池包壳体内,可以在不增加成本和整车质量的情况下,降低托底事故中对动力电池单体造成的损伤,提高电池包在托底事故中的安全可靠性。
