The electric vehicle revolution is picking up speed, and with new models boasting more miles per charge than ever, range anxiety is becoming a thing of the past. However, the burning question on everyone’s mind is: just how long does it take to charge an electric car?
Charging speeds are a bit of a puzzle, dependent on factors like the type of charger, your vehicle, and even the weather. So, let’s dive into the nitty-gritty without getting too bogged down in the technical details.
Decoding the Speeds: It’s Like Gas Pumps, but for Electrons
In the world of EV charging, think of chargers as gas pumps. The bigger the hose and nozzle, the more electrons can flow through. Volts act like the pressure pushing electrons, while amps determine the number flowing. Home chargers, especially those with higher amperage ratings, can juice up your ride faster than their lower-amperage counterparts.
Public chargers advertise in kilowatts (kW), indicating their charging speed. While DC fast chargers boast rates of up to 350 kW, Level 1 and Level 2 chargers offer 1.4 kW and up to 7.6 kW, respectively.
However, your vehicle plays a crucial role too. Fast chargers can deliver high speeds, but only models equipped with 800-volt capability can fully capitalize on this rapid charging.
Levels of Charging: From Snail’s Pace to Warp Speed
Charging is categorized into three levels. Level 1, the slowest, plugs into a standard household outlet, offering a mere 3-5 miles of range per hour. It’s a last resort for most, with Level 2 being the go-to for many. Although it might require some wiring upgrades, Level 2 can replenish up to 30 miles of range per hour, making it a worthwhile investment.
For the speed demons, there’s DC fast charging, often referred to as Level 3 or Supercharging. With speeds of up to 20 miles of range per minute, it can restore an EV’s battery from 10% to 80% in under 30 minutes. However, due to installation costs and power requirements, you won’t find these at your neighbor’s house.
Battling the Elements: How Weather Impacts Charging
While Southern Californians bask in the sun, others face wintry challenges. Cold weather can slash an EV’s range by up to 40%, primarily due to climate controls and heating. Charging slows down in the cold, not just because of the weather but also due to the vehicle’s software and protection systems.
Charging in extreme cold can harm the battery, leading to slower charging rates. Some EVs, like Teslas, combat this with battery thermal conditioning systems, but it’s generally advised to avoid fast charging in frigid conditions.
800-Volt Architecture: The Future of Faster Charging
Think of volts as the pressure pushing electricity. More volts mean more electrons flowing, resulting in quicker charging. Most EVs now use 400-volt systems, but the shift towards 800-volt architecture promises faster charging times across the board. This upgrade not only enhances efficiency but also contributes to lighter vehicles with improved regenerative braking capabilities. The future of EVs is looking brighter and faster with 800 volts leading the charge.
