What is the charging time for a fully depleted battery using a portable EV charger?

by eddie•

As a supplier of portable EV chargers, I often get asked about the charging time for a fully depleted battery using our products. This is a crucial question for electric vehicle (EV) owners, as understanding the charging time can significantly impact their travel plans and daily routines. In this blog, I’ll delve into the factors that influence the charging time and provide a comprehensive overview of what you can expect when using our portable EV chargers. Portable EV Charger

Understanding the Basics of EV Charging

Before we discuss the charging time, it’s important to understand the different types of EV chargers and their power outputs. There are three main levels of EV chargers: Level 1, Level 2, and DC fast chargers.

  • Level 1 Chargers: These chargers use a standard 120-volt household outlet and typically provide a charging rate of about 2-5 miles of range per hour. They are the slowest type of charger but are convenient for overnight charging at home.
  • Level 2 Chargers: Level 2 chargers operate on a 240-volt circuit and offer a much faster charging rate, usually between 10-60 miles of range per hour. They are commonly used in residential settings, workplaces, and public charging stations.
  • DC Fast Chargers: DC fast chargers are the fastest option, capable of providing up to 80% charge in as little as 30 minutes. However, they require specialized equipment and are typically found at public charging stations.

Our portable EV chargers are primarily Level 1 and Level 2 chargers, which are suitable for most EV owners’ daily charging needs.

Factors Affecting Charging Time

The charging time for a fully depleted battery using a portable EV charger depends on several factors, including:

  • Battery Capacity: The larger the battery capacity, the longer it will take to charge. EVs come with a variety of battery sizes, ranging from around 20 kWh to over 100 kWh. For example, a small EV with a 20 kWh battery will charge much faster than a large SUV with a 100 kWh battery.
  • Charger Power Output: The power output of the charger determines how quickly it can deliver energy to the battery. Our portable Level 1 chargers typically have a power output of 1.4-1.9 kW, while our Level 2 chargers can range from 3.3 kW to 7.7 kW. A higher power output means faster charging.
  • State of Charge (SOC): The initial state of charge of the battery also affects the charging time. Charging a battery from 0% to 100% takes longer than charging it from 20% to 80%. This is because the charging rate slows down as the battery approaches full capacity to protect the battery from overcharging.
  • Temperature: Extreme temperatures can affect the charging efficiency of the battery. Cold temperatures can slow down the charging process, while high temperatures can cause the battery to overheat and reduce its lifespan. It’s best to charge your EV in a moderate temperature environment.

Calculating Charging Time

To calculate the charging time for a fully depleted battery using our portable EV chargers, you can use the following formula:

Charging Time (hours) = Battery Capacity (kWh) / Charger Power Output (kW)

For example, if you have an EV with a 60 kWh battery and you’re using our 7.7 kW Level 2 charger, the charging time would be:

60 kWh / 7.7 kW = 7.8 hours

Keep in mind that this is just an estimate, and the actual charging time may vary depending on the factors mentioned above.

Real-World Examples

Let’s take a look at some real-world examples to illustrate how the charging time can vary depending on the battery capacity and charger power output.

  • Example 1: Small EV with a 20 kWh Battery

    • Using our 1.4 kW Level 1 charger: 20 kWh / 1.4 kW = 14.3 hours
    • Using our 3.3 kW Level 2 charger: 20 kWh / 3.3 kW = 6.1 hours

  • Example 2: Medium-Sized EV with a 60 kWh Battery

    • Using our 1.9 kW Level 1 charger: 60 kWh / 1.9 kW = 31.6 hours
    • Using our 7.7 kW Level 2 charger: 60 kWh / 7.7 kW = 7.8 hours

  • Example 3: Large SUV with a 100 kWh Battery

    • Using our 1.4 kW Level 1 charger: 100 kWh / 1.4 kW = 71.4 hours
    • Using our 7.7 kW Level 2 charger: 100 kWh / 7.7 kW = 12.9 hours

As you can see, the charging time can vary significantly depending on the battery capacity and charger power output. It’s important to choose a charger that meets your specific needs and charging requirements.

Tips for Faster Charging

If you’re looking to reduce the charging time, here are some tips to keep in mind:

  • Use a Higher Power Charger: If possible, use a Level 2 charger instead of a Level 1 charger. The higher power output will significantly reduce the charging time.
  • Charge at a Moderate Temperature: As mentioned earlier, extreme temperatures can affect the charging efficiency of the battery. Try to charge your EV in a moderate temperature environment to ensure optimal charging performance.
  • Avoid Overcharging: Overcharging the battery can reduce its lifespan and increase the risk of damage. Most modern EVs have built-in charging management systems that prevent overcharging, but it’s still a good idea to monitor the charging process and unplug the charger once the battery is fully charged.
  • Plan Your Charging Sessions: If you’re on a long trip, plan your charging sessions in advance to ensure you have enough time to charge your EV. Use a charging app or website to find nearby charging stations and check their availability.

Conclusion

In conclusion, the charging time for a fully depleted battery using a portable EV charger depends on several factors, including the battery capacity, charger power output, state of charge, and temperature. By understanding these factors and following the tips mentioned above, you can optimize the charging process and reduce the charging time.
