A guide to EV charging

Everything you need to know about your electric vehicle’s charging speed.

Are you ready to explore the world of electric vehicles (EVs) and become a proud EV owner? One crucial aspect that can greatly affect your decision when choosing an EV model is its maximum charging capacity, which will determine your charging routine, whether at home or on the road. To save you some time from endless research, we’ve gathered valuable charging information and provided highlights of popular EVs in Ontario, including their maximum charging speeds.

Understanding EV charging.

Before choosing an electric vehicle based on its maximum charging speed, two important concepts are essential to grasp – charging curve and charging peak. Let’s explore these terms below:

Charging curve

A charging curve is a graphical representation of how an electric vehicle’s battery undergoes charging over time. It shows the maximum charge your vehicle can get throughout the charging process.

Most EV drivers notice that their EV charges most optimally when the battery level is between 10% and 80%. However, charging slows when the battery level goes above 80%. This is because it has reached the battery’s maximum charge rate (around 80%) and gradually reduces as it nears full capacity.

Peak charging

One common misconception is that electric vehicles can reach their maximum charging speed at any time. For example, if your EV’s maximum charging speed is 200 kW, it’s easy to assume that every time you plug into a 200-kW public fast charger (L3) it will deliver that full capacity each time. However, it doesn’t always work that way. For example, let’s say that your EV is at 10% and you plug into a 250-kW unit. Your vehicle may quickly reach its maximum charging speed (200 kW), but eventually, it will slow down as the battery charges. It’s the gradual increase and decrease that creates the charging curve.

Keep charging curves in mind when you can prepare for long-distance journeys. You can decide on the ideal charging stops based on the average charging session length and amenities available nearby. Thankfully, at highway service centres like ONroute in Ontario, you can charge your car at Ivy chargers while enjoying refreshments or taking a washroom break.

External factors that may affect your charging speed.

Additionally, several other external factors may affect your charging speed:

State of charge (SoC)

State of charge, or SoC, refers to how full your battery is. The higher the SoC, the slower the charging speed. This is due to charging slowing down when the battery approaches its maximum capacity to avoid overcharging and potentially causing battery damage. The recommended approach is to keep your EV’s battery between 20% and 80% and only charge beyond this when it is necessary.

Battery temperature

Charging speed can also be affected by extreme temperatures limiting charging efficiency and sometimes even causing damage to your battery. During hot summer months, park your EV in a shady area or in a garage to help keep the battery cool. During the winter, it is best to charge right away while your EV is warm or use a pre-conditioning tool on your EV’s app to warm up your vehicle before charging.

Other electrical loads

If you’re using electrical loads in your EV while charging such as air conditioning, heating or entertainment systems, some of your charging power may be diverted to power these loads which can slow down your charging speed.

Electric vehicle models and their maximum charging speeds.

One charging speed doesn’t fit all! Every auto manufacturer has different specs for their EV battery capacity so it’s important to find out what applies to your vehicle. We’ve compiled a list below of popular EVs in Ontario and their maximum charging speeds. It is always vital to consult and follow your vehicle’s manufacturer guidelines for charging recommendations specific to your electric vehicle.

Ivy Charging Network launches first complete electric vehicle charging solution for home and on the go

Ivy Home™ offers a made-in-Ontario, built-for-Ontario product

TORONTO, February 16, 2023 — It just got easier to go electric with the launch of Ivy Home™, Ontario’s first complete EV charging solution. Ivy Charging Network, one of Ontario’s largest and most connected electric vehicle (EV) charging networks, is now offering a home charger with professional installation, a 3-year warranty, 24/7 member support, and access to Ivy’s public charging network.

“With nearly 90 per cent of EV charging happening at home, we are simplifying home charging with a one-stop solution. Customers pick their charger, monthly plan and we’ll take care of the rest,” said Michael Kitchen, General Manager, Ivy Charging Network. “At Ivy, we’re committed to helping customers make the switch to an electric vehicle by providing simple, intuitive, and reliable charging solutions.”

Currently, transportation is responsible for about a third of Ontario’s greenhouse gas emissions. Mobilizing Ontario’s clean electricity system to power transportation is key to the province’s net zero future.

The company received support, thanks to a funding investment of $922,934 from Natural Resources Canada’s Electric Vehicle Infrastructure Demonstration Program.

“We’re making electric vehicles more affordable and charging more accessible where Canadians live, work and play,” said the Honourable Jonathan Wilkinson, Minister of Natural Resources. “Investing in more EV chargers will put more Canadians in the driver’s seat on the road to a net-zero future and help achieve our climate goals.”

Quick facts
• The Ivy Home Level 2 Smart Charger is powered by Grizzl-E™, hardware that is built in Ontario to withstand harsh Canadian weather including temperatures as low as -30ºC.
• Portable and compatible with all EV models and delivers charging speeds of up to 10 kW so you can charge up to 48km/hour.
• Ivy Home makes home charging accessible with flexible payment plans that fit your budget.
• Ivy Home customers can access Ivy’s public charging network, including ONroute locations, by adding on a public fast charging plan.
• Ivy Home customers can manage both their public and home charging sessions through one easy-to-use mobile app.
