EV CHARGING – TOP TIPS

UNDERSTANDING THE CHARGING CAPABILITY OF YOUR DESIRED EV

• All EVs can be charged at level 1 with a household electrical socket. However, this will only provide trickle charge which is much slower than level 2 (AC charging) and level 3 (DC fast charging).​¹

• Identify what is the maximum power at which your desired EV can charge for level 2 (AC Charging). This will allow you to consider the appropriate home charging options.

○ This could be single phase (up to 7 kW)
○ Three phase (up to 11 kW)
○ Three phase (up to 22 kW)

• Identify if your desired EV can be charged at level 3 (DC fast charging) and at which maximum power rating. This will allow to you consider the appropriate public chargers that you can use.

UNDERSTANDING CHARGING OPTIONS FOR YOUR HOME²

• If you reside in a villa or townhouse, most likely you would be able to install a level 2 charger in your garage

○ The compound engineer or a certified installer would be able to check the electrical distribution board of your house to determine the available power for the EV charger to safely consume
○ Based on the availability of power you would be able to decide whether a single phase or three phase AC charger can be safely installed along with its specific electrical power capacity

○ Does the apartment building/tower already have chargers installed
○ Are there any public chargers nearby for your regular usage
○ If none of the above two points apply, then you may want to inquire with the building/tower management to see if you can install a charger for your use
○ This will allow you to consider the appropriate public chargers that you can use.

HOME CHARGING

• Dual Level Charge Cord³comes standard with the Hummer EV. Can be switched between level 1 and level 2 charging.
  
  
  • Plug in to your standard household electrical wall socket for Level 1 charging
  • Level 2 charging (up to 7kW) may require professional installation and requires an industrial power outlet. Please contact your local dealer for further details.

• Level 2 home charger wall box⁴ capable of single to three phase charging up to 22 kW
  
  
  • Level 2 charging (up to 22kW) require professional installation.
  • Approval for additional three phase power supply may be required from your local electricity authority
  • Please contact your local dealer for further details and available home charging options
  • Some countries require the home charger installation to be conducted by certified installers and may require additional approvals to be attained from the local electricity or other regulatory authorities.
  • Please ensure that you adhere to local regulations for safe and proper EV charger installation

PUBLIC CHARGING

• Charge using a level 2 (AC) public charging station
  

  
  

  • Public charging stations can be located using the myGMC app
  • Some public charging stations may require you to scan or use a designated charging app or card which may incur a fee
  • Different countries have varying charging operators – with each one possibly requiring their own designated app or card to be used
  • There are two types of public AC chargers
    

    
    

    • With integrated charging cable – with this type of charger you can just scan your charging card (if paid) and plug in the integrated type 2 cable into your vehicle
    • Without a charging cable – with this type of charger you would need to scan your charging card (if paid) and then plug in your own detachable type 2 to type 2 charging cable. Please contact your local dealer for details on how to purchase your own type 2 to type 2 charging cable.

• DC Fast Charging (DCFC) Public Stations

• Public charging stations can be located using the myGMC app
• They are usually located in malls, petrol stations and highways
• DCFC ranges from 50kW all the way up to 350kW – with most petrol stations in GCC currently having 50kW DCFCs
• All DC fast charging stations have integrated charging cables due to the very high voltage and current flowing through them
• You may be required to pay to use some of these public DC fast charging stations (varies from different charging operators in different countries)

​

DO'S

DONT'S​​

• Maintain your state of charge (SOC) between 20% - 80% for optimal battery performance
• Appropriately plan your home charging cycle as per your daily commute
• Take care of your EV’s battery. Keeping the battery at zero and repeatedly charging it will cause the battery to deplete more quickly.
• Protect your EV from prolonged exposure to heat. Try to park your EV under a shade
• While using a DC fast charger utilize the battery preconditioning feature for a more efficient fast charging experience
• For optimal charging speeds keep the air conditioning switched off

• Avoid parking your EV directly under the sun as this can affect battery life
• Avoid waiting until the last minute to charge your EV to prevent range anxiety
• Avoid driving over the charging cable to prevent damage of the equipment
• Avoid plugging your EV charger into old/worn-out sockets
