The charging port on a 2015 BMW i8 is located on the driver's side, behind a motorized cover that opens when you unlock the car or press a button inside

The 2015 BMW i8 has a single charging port positioned on the driver's side of the vehicle, roughly midway between the front and rear wheels. Unlike gas cars with a straightforward fuel door, the i8's charging port sits behind a motorized cover that retracts automatically. This cover opens when you unlock the vehicle with your key fob, or you can open it manually by pressing a button on the dashboard or the door panel itself.

The port itself is a standard SAE J1772 connector, which is the most common plug type for Level 1 and Level 2 charging in North America. This is the same connector type used by most other plug-in hybrid and electric vehicles sold in the United States during that time period. The motorized cover protects the port from weather and debris when the car is parked.

Key Takeaways

  • The charging port is on the driver's side of the vehicle, behind a motorized cover that opens automatically when you unlock the car.
  • You can also open the cover manually using a button on the dashboard or door panel if the motorized system is not working.
  • The 2015 i8 uses a SAE J1772 connector, which works with most Level 1 and Level 2 chargers available at home and public charging stations.
  • The cover protects the port from weather and dirt, and it retracts fully into the vehicle body when opened.

How to open the charging port cover

The easiest way to open the cover is to unlock your car with the key fob or keyless entry system. The cover will retract automatically as part of the unlocking sequence. If you are already inside the vehicle, you can press the charging port button on the dashboard — it is typically located on the lower left side of the instrument panel, near the door. Some models also have a manual release button on the door panel itself.

If the motorized system fails and the cover will not open, you can access the manual release. Look for a small access panel or lever near the charging port on the outside of the vehicle. Consult your owner's manual for the exact location, as the manual release mechanism varies slightly depending on your specific vehicle configuration. In most cases, you can gently pull or press this lever to retract the cover by hand.

What type of charger works with the 2015 i8

The 2015 BMW i8 accepts both Level 1 and Level 2 charging through its SAE J1772 port. Level 1 charging uses a standard 120-volt household outlet and comes with an adapter cable in your vehicle. This method is slow — it adds roughly 2 to 3 miles of range per hour of charging — but it requires no special equipment or installation.

Level 2 charging uses a 240-volt circuit and is much faster, adding 10 to 25 miles of range per hour depending on the charger's power output. Level 2 chargers are available at home (if you install a dedicated circuit), at workplaces, and at public charging networks. The i8 does not support DC fast charging, so you will not be able to use Tesla Superchargers or other rapid-charging networks that require a different connector type.

Charging at home versus public stations

If you charge at home, you will need a Level 2 charger installed by a licensed electrician. This requires running a 240-volt line to your garage or parking area, which typically costs between $500 and $2,000 depending on how far the line needs to run and your local electrical codes. Once installed, home charging is the most convenient option because you can charge overnight and start each day with a full battery.

Public charging stations are scattered across most urban and suburban areas. You can find them through apps like PlugShare, ChargePoint, or Electrify America. Many are free, though some charge a fee per session or per kilowatt-hour. Public chargers are useful for road trips or if you do not have a garage, but they are slower than home charging and require you to plan around their locations and availability.

Protecting the charging port cover from damage

The motorized cover is durable, but it can be damaged by ice buildup, debris, or repeated impacts. In winter, clear any ice or snow from around the port before opening it, as ice can jam the mechanism. Do not force the cover open if it feels stuck — this can damage the motor or the cover itself. If the cover will not open or close smoothly, check for debris around the edges and clean it gently with a soft cloth.

If the motorized system stops working entirely, you can still charge using the manual release, but you should have the motor inspected by a BMW service center. Repair costs vary, but motorized cover replacement typically runs $300 to $600 in parts and labor. Keeping the area around the port clean and dry will extend the life of the mechanism.

What to do if the cover gets stuck

A stuck cover usually means debris has accumulated around the edges or the motor has lost power. First, check that your vehicle is unlocked and has adequate battery charge — the motorized cover draws power from the main battery. Try pressing the charging port button on the dashboard again and wait a few seconds for the motor to respond.

If the cover still does not move, inspect the edges for dirt, leaves, or ice and gently remove any visible obstruction. Do not use tools or explore force. If you cannot free it, use the manual release lever to open it by hand, then have the motorized system inspected at a BMW service center. Attempting to force a stuck cover can damage the motor or the cover's tracks.

Frequently Asked Questions

Can I charge the 2015 i8 with a Tesla charger?

No. Tesla Superchargers use a proprietary connector that is not compatible with the SAE J1772 port on the i8. You can only use Level 1 and Level 2 chargers designed for the J1772 standard. Some newer public charging networks offer multiple connector types, so always check before you arrive.

What happens if I leave the charging port cover open?

The port will be exposed to rain, dirt, and debris. While the connector itself is designed to handle some moisture, leaving it open for extended periods increases the risk of corrosion or contamination. Always close the cover when you are not actively charging. The cover will close automatically when you lock the vehicle.

Does the charging port cover drain the battery?

The motorized cover draws a small amount of power from the main battery each time it opens or closes, but the amount is negligible. You will not notice any meaningful impact on your driving range or battery health from normal use of the cover.

Can I manually push the cover closed if it gets stuck open?

You can gently guide it, but do not force it. If the motorized system is not responding, the cover may be jammed or the motor may have lost power. Forcing it can damage the tracks or motor. Use the manual release to find it in the closed position, then contact a BMW service center.
