Based on our analysis, majority of charging stations for long-haul battery-electric trucks will adopt the option to directly charge from the grid (option 1) for the present scenario. However, it should be noted that there are certain additional benefits from having intermediate storage which was not explicitly considered in this analysis. First, batteries can be preferentially charged when the grid has a higher share of renewables, thereby reducing the carbon footprint of trucks. Similarly, charging during off-peak hours can reduce costs. Next, credits can be earned by providing grid stabilization services which can add further savings to the operating costs. Evaluating these options would require a region-wise analysis, accounting for irregular charging cycles, real-time energy prices, and more, which is out-of-scope for this work.
