as electric vehicles become more common in our region, its important to understand the charging options available and which one works with your lifestyle. Whether you’re a new EV owner or considering an electric vehicle, we’ll help you navigate the current infrastructure for owning a vehicle in Big Sky.

ev charging

Electric vehicles (EVs) and plug-in electric hybrids have an electric motor using electricity stored in a battery. According to the Department of Energy, most EV owners do more than 80% of their charging at home because it is the most affordable and convenient option, especially if it utilizes solar power. Below are the basics of EV Charging. 

‍

charging speed

level 1 charging 

• uses a regular household outlet (120-volt plug).
• charging cord is typically provided with the car.
• can take over 24 hours to deliver an optimal battery charge of 80%.
• generally used for emergency recharging and often kept in the vehicle’s trunk.
• charges one vehicle at a time (the plug is not interchangeable with other appliances).

level 2 charging 

• the fastest way to charge your EV is at home.
• requires a 240 volt plug, which must be wired directly into your home’s electrical supply by a certified electrician.
• delivers an optimal battery charge of 80% in 4 to 5 hours.
• convenient, easy to use, reliable, and saves money.

level 3 charging

level 3 charging stations, also known as direct current (DC) fast charging, require an energy level that surpasses what’s available at home. They can deliver a full charge in about 30 minutes but cost thousands of dollars to install. 

• requires an energy level that exceeds residential capabilities.
• can deliver a full charge in about 30 minutes.
• installation costs are typically in the thousands of dollars.

equip your home with a Level 2 charging station

if you plan on charging your EV at home, equip your house with a level 2 charger. As more EV options become available, chargers increasingly vary. Some home charging stations are better suited for colder climates than other models on the market. It is important to choose a charging station that best suits your vehicle, needs, and lifestyle.

battery storage

battery energy storage systems (BESS) are rechargeable batteries that can store energy inputs from different sources and release energy when required. The battery can be used as a backup power source and, in combination with solar systems, to store excess energy during outages when the grid goes down. BESS’s can also be used to charge electric vehicles when the EV charging demand exceeds your electric capacity. This decreases your reliance on external energy systems and ensures you have power regardless of the weather or grid status.

while home batteries have a high entry cost, they decrease your energy bill and allow you to store energy when rates are lower and use it during high-demand hours when rates are higher. They also reduce the need for fossil-fuel-generated electricity and decrease greenhouse gas emissions, making them an appealing option for many living in both rural and urban towns.
