ABSTRACT For a limited set of conditions we have shown that recovering braking energy from log trucks descending from high elevation stands to lower elevation manufacturing facilities can reduce the size of the battery required to run a log truck. Adding level highway hauls after descending from the higher elevation stands quickly increases the required battery capacity. The effect of conversion efficiency on the required battery capacity is correlated with the change in elevation along the haul route. At a conversion efficiency of 100% (battery-to-wheels and wheels-to-battery), the cumulative battery usage on the base profile (elevation factor = 1.0) is only one-half of what it would have been compared to a level road of the same horizontal length (elevation factor = 0.0). When the conversion efficiency is set to 60%, the cumulative battery usage for the base profile would be the same as if the truck had been on a level road of the same horizontal distance. For the actual haul route considered in this paper the minimum battery mass required for a single round trip is limited by peak power requirements; however, energy storage becomes limiting as longer level highway haul sections are added.

从山地森林中收获海拔潜力

摘要 对于一组有限的条件，我们已经表明，从从高海拔站下降到低海拔制造设施的原木卡车回收制动能量可以减少运行原木卡车所需的电池尺寸。从较高海拔的停机坪下降后增加水平公路运输会迅速增加所需的电池容量。转换效率对所需电池容量的影响与运输路线沿线的海拔变化相关。在 100% 的转换效率（电池到车轮和车轮到电池）下，基本轮廓上的累积电池使用量（海拔系数 = 1.0）仅是与水平相比的一半相同水平长度的道路（高程系数 = 0.0）。当转换效率设置为 60% 时，基本配置文件的累积电池使用量与卡车在相同水平距离的水平道路上的情况相同。对于本文中考虑的实际运输路线，单次往返所需的最小电池质量受峰值功率要求的限制；然而，随着更长水平的公路运输路段的增加，能量存储变得有限。
