Resources & Frequently Asked Questions

Does weather affect vehicle range?

Severe weather, whether hot or cold, can affect your vehicle’s range. While temperature plays a role, using in-vehicle climate control can further impact efficiency. However, you can minimize range loss by pre-conditioning your vehicle before driving and ensuring your battery is at its optimal operating temperature before departure.

Does cargo affect vehicle range?

Many factors influence range, similar to gasoline-powered vehicles. These include passenger and cargo load, towing, wind resistance, road grade, driving style, speed, weather, and driving surface. EVs also have unique advantages, with factors like battery charge level and temperature playing a role in overall efficiency.

How much does it cost to replace a battery?

The cost of a battery replacement can vary depending on the type and size of the battery, the make and model of the vehicle and the warranty coverage. Most manufacturers warranty the battery for 8-10 years, or up to 120,000 miles. Additionally, as production volume increases and battery technology advances, the cost of battery replacements continues to decrease.

What kind of warranties are available for EVs?

Many warranties may be available for electric vehicles and the exact coverage varies between manufacturers. Typically, customary warranties are offered covering the vehicles' components with a separate warranty on the battery (8-10 years, up to 120,000 miles). Aftermarket warranties may also be available when a used electric vehicle is purchased.

Additionally, manufacturers of home charging equipment may also have warranties available.

How much do EVs cost in comparison to gas-powered vehicles?

While the upfront cost of an electric vehicle is still slightly higher than a combustion engine, the price gap is shrinking each year as production and battery costs decline. However, when considering the total cost of ownership, EVs often come out ahead due to lower fueling and maintenance costs, discounted electricity rate programs, incentives, and rebates.

How much does an EV weigh?

The weight of an EV varies by model and battery size, but on average, electric vehicles tend to weigh more than their combustion-engine counterparts. This is mostly driven by the weight of the battery.

How does the performance of an EV compare to a gas-powered vehicle?

EVs are approximately 71% more efficient than gas-powered vehicles. EVs deliver instant torque and higher horsepower, providing quick acceleration. Gas-powered vehicles, on the other hand, are generally better at reaching and maintaining higher top speeds.

Do EVs affect the electrical grid?

EV drivers tend to charge their vehicles at night when, generally, energy usage is at its lowest. This creates more efficient use of the grid, which puts downward pressure on customer rates. Visit our ChargeSmart page to learn more about charging overnight.
