Introduction

As electric commercial trucks gain popularity, understanding the charging process and how long it takes to charge these vehicles becomes crucial for fleet managers. The time it takes to charge an electric truck depends on several factors, including the type of charger used, the truck’s battery capacity, and the charging infrastructure available.

Types of Chargers and Their Charging Speeds

Level 1 Chargers (120V)

  • Description: Level 1 chargers use a standard household outlet (120 volts).
  • Charging Speed: These chargers are the slowest, providing about 3-5 miles of range per hour of charging.
  • Typical Use: Due to their slow speed, Level 1 chargers are generally not suitable for commercial trucks but can be used for overnight charging if no other option is available.

Level 2 Chargers (240V)

  • Description: Level 2 chargers use a 240-volt outlet, similar to what is used for large appliances.
  • Charging Speed: These chargers can provide about 10-60 miles of range per hour, depending on the truck’s battery and the charger’s power output.
  • Typical Use: Level 2 chargers are common for home and public charging stations and can be a practical option for fleet operations if trucks have long overnight downtimes.

DC Fast Chargers (480V or Higher)

  • Description: DC fast chargers (also known as Level 3 chargers) use a 480-volt or higher power source.
  • Charging Speed: These chargers can provide a substantial charge in a short period, adding 60-200 miles of range in 20-30 minutes.
  • Typical Use: Ideal for commercial trucks, DC fast chargers are often used in public charging stations and fleet operations where quick turnaround times are essential.

Ultra-Fast Chargers

  • Description: The latest in charging technology, ultra-fast chargers can deliver even higher power levels, up to 350 kW or more.
  • Charging Speed: These chargers can add up to 300 miles of range in about 30 minutes, depending on the truck’s battery capacity.
  • Typical Use: Ultra-fast chargers are being deployed in select locations and are ideal for long-haul trucks and routes requiring rapid charging.

Factors Influencing Charging Time

Battery Capacity

  • Description: Larger batteries take longer to charge but provide greater range.
  • Impact on Charging Time: Trucks with larger battery capacities will require more time to reach a full charge, even with fast chargers.

State of Charge (SoC)

  • Description: The current level of charge in the battery before charging begins.
  • Impact on Charging Time: Charging from a low SoC to full takes longer than topping off a partially charged battery. Fast chargers also slow down as the battery approaches full capacity to prevent damage.

Battery Preconditioning

  • Description: Some electric vehicles are able to precondition their batteries, essentially warming them up before the vehicle arrives at a charging location.
  • Impact on Charging Time: Batteries charge most efficiently within a certain temperature range, typically around 20-25°C (68-77°F). Preconditioning ensures the battery is within this optimal range, allowing for faster charging rates.

Charger Power Output

  • Description: The power rating of the charger in kilowatts (kW).
  • Impact on Charging Time: Higher power output reduces charging time. For example, a 150 kW charger will charge faster than a 50 kW charger.

Charging Infrastructure

  • Description: Availability and accessibility of charging stations.
  • Impact on Charging Time: Having access to multiple fast chargers can reduce wait times and improve overall efficiency in fleet operations.

Environmental Factors

  • Description: Temperature and weather conditions.
  • Impact on Charging Time: Extremely cold or hot temperatures can affect battery performance and charging efficiency, potentially increasing charging times.

Vehicle Specifications

  • Description: The truck’s specific design and technology.
  • Impact on Charging Time: Different truck models have varying battery chemistries and charging capabilities, which can influence charging speed and efficiency.

Best Practices for Efficient Charging

Plan Charging Times

  • Tip: Schedule charging during off-peak hours or when the trucks are not in use to maximize efficiency and reduce costs.

Utilize Fast Chargers

  • Tip: Invest in or partner with locations that offer DC fast chargers to minimize downtime and keep your fleet operational.

Monitor Charging Progress

  • Tip: Use fleet management software to monitor charging progress and optimize schedules.

Maintain Optimal Battery Health

  • Tip: Avoid deep discharges and overcharging to extend battery life and maintain efficient charging times.

Implement Return-to-Base Charging

  • Tip: Establish charging infrastructure at fleet bases to ensure trucks can charge overnight or during scheduled downtimes.
