The invention discloses an intelligent charging control method for a new energy automobile. The intelligent charging control method comprises the following steps that S10, a key is off, and high voltage is turned off; step S20, judging whether intelligent power supply is triggered or not, if so, triggering the intelligent power supply after the travelling crane is powered off, and then performing the step S30, and if not, repeating the judgment; s30, judging whether the SOC of the high-voltage battery is lower than a threshold value or not, if not, executing the step S40, and if yes, executing the step S70; and S40, after delaying for 3 minutes, controlling the whole vehicle to be in high voltage again to charge the low-voltage storage battery. The low-voltage storage battery is ensured to be fed or have a feeding trend even if the whole vehicle runs under the extreme working condition, meanwhile, the whole vehicle is also perfectly ensured not to lie down due to the feeding of the low-voltage storage battery even under the extreme working condition, the capability and the function robustness of the product in dealing with the extreme working condition are improved, the economic loss of a user is avoided, and the user experience is improved. And the vehicle use experience of the user is ensured.

    本发明公开了一种新能源汽车智能补电控制方法,包括以下步骤:步骤S10,钥匙off下高压;步骤S20,判断是否触发智能补电,若是则触发行车下电后的智能补电,再进行步骤S30,若否则重复进行判定;步骤S30,判断高压电池SOC是否低于阈值,若否则进行步骤S40,若是则进行步骤S70;步骤S40,延时3分钟后控制整车再次上高压对低压蓄电池进行补电。本发明保证即使极端工况整车运行后低压蓄电池出现了馈电或出现了馈电趋势,同时也完美保证了即使出现极端工况,整车也不会由于低压蓄电池馈电导致趴窝,提升了产品应对极端工况的能力和功能鲁棒性,避免了用户的经济损失,保证了用户的用车体验。
