The invention relates to the technical field of vehicles, in particular to a vehicle fast charging and boosting control method and device, a vehicle and a storage medium, and the method comprises the steps that the maximum allowable charging power of the current vehicle fast charging and boosting function is calculated, and whether a current direct current fast charging pile meets the maximum allowable charging power or not is judged; if the current direct current fast charging pile does not meet the maximum allowable charging power, the maximum allowable charging power of the current vehicle is reduced according to a preset derating strategy until the current direct current fast charging pile meets the new maximum allowable charging power; and controlling the current direct current quick charging pile to charge the current vehicle based on the new maximum allowable charging power. Therefore, the problem that the fast charging and boosting function is difficult to implement due to the difference of the power characteristics of the charging piles of different brands is solved, the adaptability of the vehicle to the charging infrastructure in the direct-current fast charging process is improved, the output power of the charging piles is fully utilized on the basis of ensuring the stability and reliability of the fast charging and boosting function, and the cost is reduced. And the vehicle charging efficiency is improved.
本申请涉及车辆技术领域,特别涉及一种车辆快充升压控制方法、装置、车辆及存储介质,方法包括:计算当前车辆快充升压功能的最大允许充电功率,并判断当前直流快充桩是否满足最大允许充电功率;若当前直流快充桩不满足最大允许充电功率,则按照预设降额策略降低当前车辆的最大允许充电功率,直至当前直流快充桩满足新的最大允许充电功率;控制当前直流快充桩基于新的最大允许充电功率为当前车辆充电。由此,解决了因不同品牌充电桩的充电桩功率特性差异导致快充升压功能实施困难的问题,提高了车辆在直流快速充电过程中对于充电基础设施的适应性,在确保快充升压功能稳定、可靠的基础上,充分利用充电桩的输出功率,提高了车辆充电的效率。
