How to Charge Electric Vehicle in Cold Weather?

Do You Own EV Charging Stations Yet?

With the rising popularity of electric vehicles (EVs), many drivers opt for new energy electric cars to align with green initiatives. This has brought about a redefinition in how we charge and manage energy. Despite this, many drivers, particularly those residing in areas with extreme weather conditions, remain hesitant about the safety of charging their electric vehicles.

Where Need Electric Car Charging In Extreme Cold?

As the EV industry continues to expand rapidly, the quality of EV charging equipment available on the market is variable. The harsh and complex weather conditions necessitate more rigorous requirements for the stable performance of EV charging equipment. This challenges electric vehicle enterprises in sourcing suitable EVSE charging equipment.

Current Situation Of The Electric Vehicle Charging Industry​

Northern Europe, for instance, is renowned for its freezing weather. Countries such as Denmark, Norway, Sweden, Finland, and Iceland are situated at the world’s northernmost point, where winter temperatures can plummet to as low as -30°C. During Christmas, daylight hours can be limited to just a few.

Furthermore, parts of Canada have sub-polar climates where snow remains on the ground throughout the year, and winter temperatures can drop as low as 47 degrees Celsius. Inclement weather makes travel a more cautious endeavor.

Impact Of Extreme Weather On Electric Car Charging

You may have observed that using your mobile phone in frigid outdoor temperatures can diminish its battery life, whereas excessive heat can cause it to shut down. This phenomenon is attributed to batteries, whether in cell phones, laptops, or vehicles, having an optimal operating temperature range that maximizes energy efficiency. The same principle applies to the batteries in electric vehicles, which, like humans, function less efficiently when exposed to temperatures outside their preferred range.

In winter, wet and snowy road conditions increase the resistance electric vehicles must overcome while driving, leading to greater electricity consumption than on dry roads. Moreover, shallow temperatures impede the chemical reactions inside the battery, reducing its power output and potentially decreasing the range, albeit without harming the batteries over the long term.

In severe weather conditions, electric vehicles typically experience an average range reduction of around 20%, compared to a 15-20% decrease in MPG for internal combustion engine vehicles. As a result, electric vehicle drivers need to charge their vehicles more frequently than during favourable weather conditions. Selecting appropriate and reliable charging equipment for electric vehicles is also a crucial factor to consider.

What Are The Available Charging Options For Electric Vehicles?

The primary component powering an electric vehicle is the electric motor, which relies on the battery for energy. There are two predominant methods for charging these batteries: AC charging and DC charging.

One of the more widely and safely used charging options than DC EV charging is AC charging, which is also the recommended method for all-electric car owners, according to BESEN. Within the realm of AC charging, a built-in car charger exists. This device receives AC (alternating current) power as input, subsequently converted to DC (direct current) power before being transmitted to the battery.

This is necessary because the battery is only compatible with DC power. Built-in chargers are the most commonly used option for home and overnight charging. Charging speeds of AC EV chargers range from 3.6 kW to 43 kW/km/h, making them suitable for use in extremely cold weather conditions and providing a safe and efficient means of charging electric cars.

What Is BESEN’s Recommended Electric Vehicle Supply Equipment?

EV Charging Principle In Extremely Cold Weather

In cold conditions, the charging goal is to gently warm the battery by gradually increasing the amount of electricity it receives. If you switch it on abruptly, there is a risk that some aspects of the battery will heat up faster than others, which could exert stress on the chemicals and materials forming the battery, potentially causing damage. Therefore, it is recommended to gradually turn the dial so that the battery as a whole heats up and is ready to receive the entire flow of electricity. This means that you may experience slightly longer charging times in colder weather. However, this has little impact on your overall charging experience – waiting a few extra minutes is much better than risking potentially unsafe charging.

EV Charging Technology Improvement

Electric car manufacturers are improving temperature-control technology to compensate for some of these problems. For instance, several models now come equipped with battery heaters or other technologies to heat the battery and improve efficiency in cold climates.

Other Tips To Help You Recharge During Extremely Cold Weather

Here are some tips to help drivers improve their electric cars’ efficiency, anticipate how they will perform in extreme temperatures, and brave the challenges of cold weather.

  1. Make the electric car warmer.

If you have a choice of parking lots or outside, choose parking lots warmer for batteries. We can manually build rain and snow protection facilities for household charging equipment.

  1. Use accessories wisely.

The inclusion of accouterments, namely the warming and cooling widgets and entertainment systems, undoubtedly impact the fuel efficiency of all modes of transportation. Still, their influence is even more pronounced regarding electric vehicles. Using seat and steering wheel heaters instead of heaters can save energy and extend your range.

  1. Start warming the electric vehicle in advance.

Pre-heating or pre-cooling the cabin of an all-electric or plug-in hybrid electric vehicle while it is still plugged in can extend its electric range, especially in extreme weather.

  1. Use the economy mode.

Many electric vehicles have an “Economy model” or similar feature that maximizes fuel economy. Economy mode may limit other aspects of vehicle performance, such as acceleration, to fuel savings.

  1. Obey the speed limits.

At speeds over 50 miles per hour, efficiency usually declines.

  1. Keep your tires in good condition.

Check tire pressure, keep tired adequately inflated, avoid dragging goods on the roof, remove excess weight, and improve efficiency.

  1. Avoid hard braking.

Avoid hard braking and anticipate braking situations. As a result, the vehicle’s regenerative braking system is enabled to retrieve kinetic energy from the car’s forward movement and retain it in the form of electrical power.

Conversely, abrupt braking necessitates using the conventional friction brakes of the vehicle, which cannot recycle energy.
