How long does it take to charge an electric vehicle?
July 10, 2025
Key insights:
-
Charging times are influenced by multiple factors such as battery size, charger type, state of charge, and environmental conditions. For example, charging slows significantly once the battery reaches 80% to protect its lifespan.
-
Level 2 chargers enable faster charging compared to Level 1 and are suitable for routine depot charging. They can deliver approximately 25-50 miles per hour.
-
Battery preconditioning improves charging efficiency by adjusting the battery to an optimal temperature, especially in extreme cold or heat.
-
Following best practices extends EV battery life, including maintaining a 20%-80% charge range, avoiding prolonged high voltage exposure, and using telematics to optimize routes and charging cycles.
Electric vehicles (EVs) are rewriting the rules of fleet management, driving down certain costs while helping achieve sustainability targets. But how long does it actually take to charge an EV? If managing downtime or scheduling routes feels like solving a puzzle, you're not alone. Charging times aren't as straightforward as topping off a gas tank. They depend on everything from battery size to weather conditions.
For fleet managers, understanding these factors is essential to maintaining seamless operations while reducing costs and downtime. This blog explores the nuances of electric vehicle charging, explains what determines charging times, and also provides actionable strategies to improve charging efficiency.
What determines EV charging time?
EV charging time is influenced by a variety of factors. Recognizing these variables will allow you to plan more effectively. Here’s what you need to know:
- Charger power
The higher the power output of a charger, the faster it can transfer energy to an EV battery. For example, a 150 kW DC fast charger will charge significantly quicker than a 7 kW Level 2 charger.
-
Battery capacity and chemistry
Larger batteries take longer to charge, as they store more energy. Advanced batteries, such as those with solid-state chemistries or silicon-enhanced anodes, can handle higher power inputs, reducing charging time. -
State of charge (SOC)
EVs charge fastest when their battery is between 10% and 50% full. Beyond 50%, charging gradually slows, and after 80%, the rate decreases significantly to preserve battery life. -
Battery conditioning and temperature
Extreme cold or heat can slow charging rates. Preconditioning the battery by warming or cooling it to an optimal temperature ensures faster and more efficient charging, especially when using DC fast chargers. -
Vehicle onboard charging limits
Each EV has a maximum charging rate it can accept. For instance, even if a charger provides 350 kW, the rate will be limited to the vehicle's onboard charging capability, which might cap at 150 kW or less. -
Grid and infrastructure constraints
Shared chargers, limited transformer capacity, or inadequate cable infrastructure can reduce the available power per connector, leading to slower charging sessions, particularly at busy charging sites.

Recommendations to maximize EV battery lifespan and charging efficiency
Maximizing the lifespan of batteries and enhancing charging efficiency requires adopting tailored best practices for EV fleet management. Here are key strategies designed to keep electric fleets running smoothly and cost-effectively:
- Maintain optimal state of charge (SOC)
Charging your EV batteries between 20% to 80% SOC is crucial for preserving battery health and reducing charging time. Frequent deep discharges (depleting the battery beyond 20%) or full charges should be avoided, as they accelerate battery degradation. For fleets, this range keeps vehicles operational while minimizing stress on the battery.
-
Tip: Use fleet management software to set automated charging schedules that stop at 80% SOC for routine use.
-
- Precondition batteries before charging
Batteries perform best and charge faster when they are at an optimal temperature. Preconditioning ensures that the battery is warmed or cooled as needed before charging, especially during extreme temperatures.
-
Tip: Enable preconditioning via the vehicle app or charging station, particularly for Level 2 and DC fast charging sessions in cold or hot climates.
-
- Prioritize Level 2 charging for routine needs
Level 2 chargers strike a balance between speed and cost-efficiency, making them ideal for depot charging. Regularly using Level 2 chargers helps maintain battery health, as rapid DC fast charging can contribute to gradual wear over time.
-
Tip: Reserve DC fast chargers for urgent top-ups or long-distance trips to maintain operational flexibility.
-
- Avoid high voltage exposures over prolonged periods
Keeping the battery charged above 90% for extended periods can stress its components, leading to capacity loss over time. Instead, aim for regular charging stops that align with daily usage habits.
-
Tip: If a vehicle must remain parked for several days, reduce the SOC to below 50% to minimize unnecessary battery aging.
-
- Adjust depth of discharge (DoD) for longevity
Operating in a narrower DoD range, such as 30% to 70%, can significantly extend the battery's lifespan. This is especially beneficial for fleet vehicles with predictable driving patterns and charging routines.
-
Tip: Plan charge cycles using fleet telematics to ensure vehicles are recharged before falling below 20% SOC.
-
- Use smart charging solutions
Dynamic load management systems can optimize energy distribution for multiple chargers, ensuring efficient depot operations. It also avoids overloading the grid during peak times.
-
Tip: Install smart chargers that regulate power based on vehicle SOC levels and prioritize fast-charging for vehicles with higher energy demands.
-
- Minimize extreme temperature exposure:
Exposing batteries to freezing (< 0 °C) or excessive heat (> 40 °C) can accelerate chemical aging and reduce overall efficiency. Parking in temperature-controlled environments or utilizing thermal management systems can mitigate these risks.
-
Tip: Install covered or climate-controlled parking spaces at depot locations to shield fleet EVs from temperature extremes.
-
- Monitor and track battery data
Using telematics and fleet management software, track key battery metrics like capacity, charging patterns, and temperature. This data enables you to identify potential issues early and schedule timely maintenance.
-
Tip: Integrate predictive analytics into your fleet system to optimize routes and charging schedules based on battery performance data.
