Maximize EV Range: Smart Charging for Work Truck Fleets
Transitioning to electric work trucks, from Class 1 cargo vans to Class 6 box trucks, presents exciting opportunities for cost savings and environmental benefits. However, a common concern for new fleet managers is maximizing the usable range of these Battery Electric Vehicles (BEVs). Nobody wants a delivery truck running out of juice mid-route! Therefore, smart charging is more than just plugging in; it’s a strategic approach to optimize battery health, extend daily range, and control operational costs. Simply put, how you charge is just as important as where you charge.
The Goldilocks Zone: Don’t Overcharge or Undercharge
Electric vehicle batteries, especially the lithium-ion types used in modern work trucks, perform best within a “Goldilocks Zone” of charge. This means keeping the battery generally between 20% and 80% full. For instance, frequently charging to 100% can degrade the battery faster over time, especially if the truck then sits fully charged for extended periods. Conversely, regularly discharging the battery below 20% also stresses it and reduces its overall lifespan. Since battery replacement is one of the most significant long-term costs for BEVs, maintaining this optimal range will significantly extend the life of your fleet’s batteries. Always aim for “just right” when it comes to charging levels.
Leveraging Off-Peak Hours and Smart Scheduling
Electricity costs vary dramatically throughout the day. Therefore, simply plugging in a fleet of Class 3 electric chassis trucks when they return to the depot at 5 PM can result in very high energy bills due to peak demand charges. However, smart charging systems allow you to schedule charging during off-peak hours, typically overnight when electricity rates are much lower. For example, by delaying the start of charging for your refrigerated electric vans until after 10 PM, you can cut energy costs by 30% or more.
Furthermore, these systems can intelligently manage power distribution, ensuring that multiple vehicles charge efficiently without overloading the grid connection. This proactive management of your charging schedule is a cornerstone of maximizing the economic benefits of your electric fleet.
The Role of Infrastructure and Charging Levels
Your charging infrastructure plays a crucial role in smart charging. For daily operations, Level 2 (AC) chargers are often sufficient for overnight charging of most work trucks, especially those with predictable routes and adequate dwell time at the depot. Since these chargers are less expensive to install than fast chargers, they represent a cost-effective solution for most fleets. However, for quicker turnarounds or route-based top-ups, DC Fast Chargers (DCFCs) can rapidly add significant range.
While DCFCs are more expensive and can generate more heat, which can slightly impact battery longevity if used exclusively, they offer necessary flexibility. Consequently, a well-designed charging strategy combines both Level 2 and DCFC options, tailored to your fleet’s specific operational needs, ensuring that every electric Class 5 stake truck is ready to roll when needed, without unnecessary battery strain or exorbitant energy costs.
