How to geek out on EV charging data: monitoring and insights for power users

If you like knowing the ins and outs of your electric vehicle (EV), your charging data is worth a closer look. Your EV and charging apps can tell you a lot about how, when, and how much you charge. Looking at this data can help you to better understand your energy use, charging habits, and what you’re generally spending on charging. And you don’t need to be an EV expert to make sense of it.

Whether you’re curious about how quickly your vehicle is charging or want to understand how much electricity you’re using at home, a few key numbers can make for a clearer picture.
Know your charging numbers

If you want to know more about your EV’s charging data, start with the numbers that tell you what’s happening during a session. Your vehicle’s dashboard or app can show some of this information while you’re plugged in, while your charging platform can help you keep track of it over time.

• Charging speed tells you how quickly electricity is being delivered to your vehicle, measured in kilowatts (kW). Depending on your vehicle, charger, and other factors, the speed can change during a charging session. Your vehicle’s dashboard or app is often the best place to see this in real time.
  
  
• Energy delivered shows how much electricity your vehicle has received during a charging session, measured in kilowatt-hours (kWh). This is the amount of energy added to your battery. Looking at kWh over multiple sessions can give you a better understanding of how much energy you typically use.
  
  
• Session duration is how long a charging session lasts. Looking at duration alongside energy delivered can help you understand how long it typically takes to add the amount of energy you need.
  
  
• Charging history lets you look beyond an individual session. It can show when you charge, how often you plug in and how much energy you typically use.

These numbers are most useful when you look at them together. A single charging session tells you what happened that day. Seeing several sessions together shows what those numbers mean for your day-to-day routine.


Look beyond a single session

Looking at your activity over time can reveal patterns that aren’t obvious from a single session. You might find that you use roughly the same amount of energy between charges, charge more often than you expected, or tend to have longer sessions after certain types of trips.

Your data can help answer some useful questions, including:

• How much energy does my EV typically use between charges?
• How often do I actually need to plug in?
• How long are my typical charging sessions?
• How much energy do I usually add in a session?

• Are there times when I could charge differently without affecting my routine?

Your charging history can also give you a better sense of what your EV needs day to day. For example, if a typical commute only uses a portion of your battery, you may not need to charge every night. If you regularly drive longer distances on certain days, you may see that reflected in your charging activity.

By tapping into the data you have available, you can spot the patterns that are useful to you. Once you know your baseline, you have a better starting point for deciding what, if anything, you want to change.


Make the most of your home charging

Home charging is one of the easiest places to put that information to work, especially if you have a connected smart charger.

We built the ChargeLab app so homeowners with select OCPP-compliant chargers can track energy usage and completed charging sessions, manage their charger, and set time-of-use schedules from one place. That gives you more control over your home charging routine.

Scheduling can be particularly useful for drivers with time-of-use electricity rates. If electricity costs less during certain hours, you can set your charger to run during those periods instead of having to remember when to plug in. You can also use your charging history to see how much energy you typically need, making it easier to set a schedule that works for your actual driving habits.

The app also lets you view completed sessions. Once a session ends, you can see details such as how long you charged and how much energy was delivered. Over time, that information can help you track your home charging costs and better understand how much electricity your EV uses.

And for eligible homeowners in Canada, there’s another way your home charging activity can add up. ChargeLab Rewards allows eligible homeowners to earn 10¢ per kWh when charging at home through a connected eligible charger. Rewards are paid quarterly and, for the average Canadian EV driver, can add up to more than $350 per year.

Turn charging data into a smarter EV routine

The more familiar you become with your charging data, the easier it is to understand what your EV needs. When you know how much energy you typically use and how often you need to charge, your routine becomes that much more predictable.

Your vehicle’s dashboard or app can show what’s happening during a session, including charging speed, while the ChargeLab app lets you track energy use, completed sessions, and costs over time, and schedule your home charging.

Your data can also help you keep a closer eye on what you’re spending on charging. Over time, seeing how much energy you use can give you a clearer picture of your charging costs and help you make choices that work better for your budget.

The biggest benefit is knowing what to expect. When charging becomes familiar and predictable, there’s less to think about each time your battery gets low. You can plan ahead, spend less time figuring things out, and feel more confident about your next drive.

That’s the power-user mindset: knowing enough about your charging data to make charging easier, more predictable, and more manageable.
