How Long Does ChargePoint Take to Charge a Tesla? The Definitive Guide

The charging time for a Tesla at a ChargePoint station varies dramatically, primarily based on two key factors: the ChargePoint station’s charging level (Level 2 or DC Fast Charging) and your Tesla’s battery state of charge (SOC). Generally, on a Level 2 ChargePoint station, expect a full charge to take anywhere from 4 to 10 hours. With a DC Fast Charger (Level 3), you could potentially add a significant charge in as little as 30 minutes to an hour, dramatically cutting down the charging time. Understanding the nuances behind these times is crucial for effective EV ownership.

Understanding ChargePoint Charging Levels

ChargePoint offers charging stations at various levels, each providing a different charging speed. It’s important to know which type you’re connecting to in order to estimate your charging time accurately.

Level 2 Charging: The Most Common Option

Level 2 ChargePoint stations are the most widely available, found in workplaces, shopping centers, and public parking lots. They typically provide 208-240 volts and can add anywhere from 12 to 30 miles of range per hour to your Tesla.

• Average Charging Time: 4 to 10 hours for a full charge.
• Factors Influencing Time: Battery size, current state of charge, and the specific amperage output of the ChargePoint station.
• Ideal For: Overnight charging at home or topping off during a workday.

DC Fast Charging (Level 3): For Rapid Replenishment

DC Fast Chargers, also known as Level 3 chargers, offer the fastest charging speeds. These powerful stations use direct current (DC) to bypass the Tesla’s onboard charger, delivering energy directly to the battery. ChargePoint operates DC Fast Chargers, though they are less common than Level 2 stations.

• Average Charging Time: 30 minutes to 1 hour for a significant charge (e.g., 20% to 80%).
• Factors Influencing Time: Maximum charging rate of the ChargePoint station, Tesla’s battery capacity and charging curve, and initial state of charge. Charging speed slows as the battery fills to protect battery health.
• Ideal For: Road trips, quick top-ups when time is limited, or when a longer charge is not possible.

Tesla’s Battery and Charging Curve

Tesla’s battery technology plays a crucial role in charging times. Different Tesla models have different battery capacities, which directly affects how long it takes to charge. For example, a Tesla Model 3 Long Range with a larger battery will take longer to charge than a Model 3 Standard Range.

Furthermore, Tesla’s charging curve dictates how quickly the battery accepts energy at different states of charge. The charging rate is typically faster when the battery is low and gradually slows down as it approaches full capacity. This is a safety mechanism to prevent overheating and prolong battery life.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions that will provide additional clarification.

1. What is the “charging curve” and how does it impact charging time?

The charging curve illustrates how the charging speed changes as the battery fills. Initially, the battery accepts a higher charging rate, which gradually decreases as the battery approaches full capacity. This reduction in charging speed protects the battery from damage and thermal overload, ultimately extending its lifespan. Expect charging to slow down considerably above 80% SOC.

2. How does temperature affect Tesla charging times at ChargePoint stations?

Extreme temperatures, both hot and cold, can impact charging times. Cold temperatures can reduce battery efficiency and slow down the charging process. The Tesla may use energy to warm the battery before it can accept a charge at the maximum rate. Hot temperatures can also limit charging speed to prevent overheating. Use Tesla’s pre-conditioning features to mitigate temperature effects.

3. Can I use the ChargePoint app to estimate charging time for my Tesla?

The ChargePoint app provides real-time information about station availability and charging status. While it may not give a precise estimate of charging time for your specific Tesla model, it can show the station’s charging speed and your charging progress. The Tesla’s onboard display is more accurate for estimating remaining charge time.

4. Are there any fees associated with using ChargePoint to charge my Tesla?

Charging fees vary depending on the ChargePoint station. Some locations offer free charging as an amenity, while others charge per kilowatt-hour (kWh) or per minute. The ChargePoint app displays the pricing information before you initiate a charging session. Be aware of potential idle fees if you leave your car plugged in after it’s fully charged.

5. What is the maximum charging rate my Tesla can handle at a ChargePoint station?

The maximum charging rate depends on your Tesla model and the specific charging equipment. Level 2 chargers typically deliver between 3.7 kW and 19.2 kW. DC Fast Chargers can range from 50 kW to over 250 kW. Consult your Tesla’s documentation to determine its maximum charging capacity.

6. Is it bad for my Tesla battery to always charge it to 100% at ChargePoint stations?

While convenient, routinely charging to 100% is not recommended for optimal battery health. Tesla advises owners to keep the battery between 20% and 80% for daily use. Charging to 100% can put stress on the battery and potentially reduce its lifespan over time. Reserve full charges for long trips.

7. What happens if a ChargePoint station is not working properly?

If a ChargePoint station malfunctions, contact ChargePoint customer support immediately. You can report the issue through the ChargePoint app or by calling their helpline. ChargePoint will attempt to resolve the problem remotely or dispatch a technician. It’s always wise to have a backup charging plan in case of station failure.

8. Can I use a Tesla Supercharger with my ChargePoint account?

No, Tesla Superchargers and ChargePoint are separate networks. Tesla Superchargers are exclusively for Tesla vehicles and require a Tesla account. You cannot use your ChargePoint account to pay for charging at a Supercharger.

9. How do I start a charging session at a ChargePoint station with my Tesla?

You can start a charging session using the ChargePoint app, a ChargePoint card, or by tapping a contactless credit card on the reader. Follow the instructions on the charging station’s screen and ensure the connector is securely plugged into your Tesla’s charging port. Monitor the charging progress through the Tesla’s display or the ChargePoint app.

10. What is the difference between kW and kWh, and how do they relate to charging my Tesla?

kW (kilowatt) is a measure of power, indicating the rate at which energy is being transferred. kWh (kilowatt-hour) is a measure of energy, representing the amount of energy consumed over time. A higher kW rating on a charging station means it can deliver more energy to your Tesla’s battery in a given time. Your electricity bill is calculated in kWh.

11. How can I find ChargePoint stations near me?

Use the ChargePoint app, the Tesla navigation system, or third-party apps like PlugShare to locate nearby ChargePoint stations. These tools provide information about station availability, charging speed, pricing, and user reviews. Planning your route ahead of time can help ensure a smooth charging experience.

12. Does ChargePoint offer any programs or discounts for Tesla owners?

ChargePoint does not have specific programs exclusively for Tesla owners. However, they offer a ChargePoint Home Flex charger for home installation and various programs for businesses and property owners to install charging stations. Check with your local utility company for potential EV charging rebates.

Maximizing Your Tesla Charging Experience

To optimize your Tesla charging experience at ChargePoint stations, keep these tips in mind:

• Plan Ahead: Use charging apps to locate stations and check availability.
• Consider Charging Levels: Choose DC Fast Chargers for rapid charging and Level 2 chargers for longer stays.
• Monitor Charging Progress: Use the Tesla’s display or the ChargePoint app to track charging speed and estimated completion time.
• Avoid Overcharging: Charge to 80% for daily use to prolong battery life.
