The invention discloses a self-learning available power acquisition method for electric automobile instrument display, and the main design concept of the invention lies in providing a self-learning available power calculation strategy, which comprises the following steps: querying a preset power parameter table through table look-up operation to obtain the maximum available power at the current moment and an attenuation factor; and performing correction according to the attenuation factor in combination with the available power, a set correction period and historical uncorrected power data to obtain target available power for instrument display. The available power value used for display can be adjusted in an autonomous judgment mode, the influence of power attenuation after the service life of the battery pack is prolonged is avoided, and the method is suitable for calculating the available power in the full life cycle of the electric vehicle.
本发明公开了一种用于电动汽车仪表显示的自学习型可用功率获取方法,本发明的主要设计构思在于,提出一种自学习型可用功率的计算策略,其中包括通过查表操作查询预设的功率参数表,得到当前时刻最大的可用功率以及衰减因子,然后根据所述衰减因子并结合所述可用功率、设定的修正周期以及历史未修正功率数据进行修正,得到用于仪表显示的目标可用功率。本发明能够以自主判断方式调整哟用于显示的可用功率数值,不受电池包使用寿命增长后功率衰减的影响,适用于电动汽车全生命周期可用功率的计算。
