The invention discloses an electric energy output control method for multiple parallel battery packs and a battery pack group, and the electric energy output control method comprises the steps: when the multiple parallel battery packs are in a normal communication state and the parameters of each battery pack are in a preset parameter range, judging the working state of an electric vehicle, when the electric vehicle is in an unlocking state, the battery pack used for outputting electric energy is confirmed according to the voltage difference value of the battery packs, when the electric vehicle is in a locking state, communication of the battery packs is disconnected, one of the battery packs is confirmed as the battery pack used for outputting electric energy, and when the electric vehicle is in a riding state, the other battery pack is confirmed as the battery pack used for outputting electric energy. And determining the battery pack for outputting electric energy according to the voltage difference value and the electric quantity difference value of each battery pack. The battery pack for outputting the electric energy can be confirmed according to the condition of the parallel battery pack and the state of the electric vehicle, so that damage to the battery pack or fire and explosion of the battery pack caused by improper parallel connection of the battery pack are avoided.

    本申请公开了一种多个并联电池包的电能输出控制方法及电池包组,该电能输出控制方法包括:在多个并联电池包是处于正常通信状态且各所述电池包的参数是在预设参数范围内时,判断所述电动车的工作状态,在所述电动车处于解锁状态时,根据各所述电池包的电压差值确认用于输出电能的电池包,在所述电动车处于锁定状态时,断开各所述电池包的通信,并将其中一所述电池包确认为用于输出电能的电池包,在所述电动车处于骑行状态,根据各所述电池包的电压差值及电量差值确认用于输出电能的电池包。本申请能够根据并联电池包的状况及电动车的状态确认用于输出电能的电池包,以避免电池包因并联不当而造成电池包的损坏或造成电池包的起火、爆炸。
