The invention relates to a method for operating a motor vehicle (2) having a cooling system (4) for cooling a traction battery (6), the method comprises the following steps: reading travel data representing the planned route; reading operating parameters of the traction battery (6); evaluating travel data and operating parameters, so as to determine a set of data representative of a predicted temperature profile (Tvor) of the battery temperature (T); evaluating the set of data of a predicted temperature profile (Tvor) of the battery temperature (T) to determine a phase (I) which has a particularly high requirement for cooling output when the route is completed; if a particularly high phase (I) of cooling output demand has been determined when the route is completed, cold energy is bufferedand stored by using the thermal storage capacity of the traction battery (6) before the particularly high phase (I) of cooling output demand during the planned route of travel, and cold energy is provided during the high phase (I) of cooling output.

    本发明涉及一种操作带有用于冷却牵引电池(6)的冷却系统(4)的机动车辆(2)的方法,包括下列步骤:读取代表计划路线的行程数据,读取牵引电池(6)的操作参数,评估行程数据和操作参数,以确定代表电池温度(T)的预测温度曲线(Tvor)的一组数据,评估电池温度(T)的预测温度曲线(Tvor)的该组数据,以确定在完成路线时对冷却输出需求特别高的阶段(I),如果已经确定在完成路线时冷却输出需求特别高的阶段(I),在行驶计划路线时,通过在冷却输出需求特别高的阶段(I)之前使用牵引电池(6)的热存储能力来缓冲存储冷能,在高冷却输出的阶段(I)期间提供冷能。
