The embodiment of the invention provides a method for dynamically adjusting power, a battery management system, equipment, a medium and a vehicle, and relates to the technical field of energy management. The method for dynamically adjusting the power comprises the steps of obtaining power information, calculating a discharge power integral value within a preset time threshold value, calculating discharge energy according to the power information, and judging whether the maximum allowable output power needs to be adjusted from first time discharge power to second time discharge power or not according to the discharge power integral value and the discharge energy. Or adjusting the maximum allowable output power from the second time discharge power to the first time discharge power. According to the embodiment, by detecting the actual state of the current battery and combining the current actual power information, the maximum allowable output power is adjusted between the short-time discharge power and the long-time discharge power, on the premise that the battery is protected, the power requirements of the whole vehicle under different working conditions are met, the driving experience is improved, battery aging is slowed down, and the service life of the vehicle is prolonged.

    本发明实施例提供动态调整功率的方法、电池管理系统、设备、介质和车辆,涉及能源管理技术领域。动态调整功率的方法通过获取功率信息,计算预设时间阈值内放电功率积分值,根据功率信息计算放电能量,根据放电功率积分值和放电能量判断是否需要将最大允许输出功率由第一时间放电功率调整为第二时间放电功率,或者将最大允许输出功率由第二时间放电功率调整为第一时间放电功率。本实施例通过检测当前电池的实际状态,结合当前实际的功率信息,在短时放电功率与长时放电功率之间调整最大允许输出功率,在保护电池的前提下,满足整车不同工况下的功率需求,提升驾驶体验,减缓电池老化,延长车辆使用寿命。
