The time it takes to charge an electric vehicle at a public charging station depends on the type of charger and the size of the battery. Level 1 chargers: These are the slowest chargers, and they can take up to 12 hours to fully charge a car. Level 2 chargers: These chargers are faster than Level 1 chargers, and they can take about 2-4 hours to fully charge a car. DC fast chargers: These are the fastest chargers, and they can take about 15-30 minutes to fully charge a car. The majority of public charging stations in Canada are Level 2 chargers. However, there is a growing number of DC fast chargers being installed. It is important to note that the time it takes to charge an electric vehicle can also be affected by the ambient temperature. In cold weather, it can take longer to charge a car because the battery has to work harder to heat up.
