To begin with, charging your EV with a dedicated charger is safer. The charger controls the flow of energy through the cable, delivering this to your EV safely. Secondly, using a charger with your EV means that you can charge approximately eight times faster than using an ordinary cable.
It is also an extremely cost-effective way to charge your vehicle; you can charge your EV at off-peak times when electricity is sometimes cheaper than normal.
Smart Charging essentially allows you to manage how your EV charges; the charger communicates with your vehicle and your electricity supplier in order to optimise the flow of power.
Smart charging manages the energy given to your plugged-in EV, taking into account the energy capacity of the supplier and your energy tariff, and economises usage of excess energy; saving time and money.
The battery capacity of your EV determines how much energy can be stored and subsequently how long it will take to charge; this differs for each vehicle.
Basically, to calculate charging time we divide battery capacity by charging power (the amount of energy that can be given to the battery every hour). Charging power depends on your supplier connection, the onboard charger in your EV and your wall-mounted charger.
For example if your EV has a battery capacity of 30kW, and the charging power available is 4Kw, then it will take 7.5 hours to fully charge your EV.
This depends on the battery capacity of your EV, but generally it is between 200 to 490 kilometres with a full charge. Battery capacity in electric vehicles is improving, alongside the charging point infrastructure worldwide. When planning a long journey, it is advisable to plan your route, checking for charging stations along the way.
This depends on the electricity rates you pay from your provider, at what time of the day you charge, and whether you charge at home or at a public charging station.
Charging your EV at a public charging station can also differ depending on the location. There may be fees such as a minute rate, or a kW rate; although many locations are beginning to offer free charging while staying or parking at their facilities.
One thing is essential when charging your EV; the connection of the charger or charging station must match the connection on your vehicle.
Four types of plug exist, two for alternating current (AC) and two for direct current (DC). AC charging allows charging up to 43kW, and DC charging allows fast charging of up to 350kW.
The four types of connection are as follows:
AC Type 1
This is common for American vehicles, and can charge up to a speed of 7.4kW
AC Type 2
This is standard for European/Asian vehicle from 2018 onwards, charging up to 43kW
This is an enhanced version of Type 2, which allows fast charging
Typically found in Asian vehicles, allowing for high charging capacities
The power that comes from your electricity supplier is AC, but batteries, like the one in your EV, store power as DC. This means that the AC power needs to be converted to DC; this is done by your vehicle’s onboard charger, which then feeds the converted power to the battery.
The difference between AC and DC charging is the location where the power is converted. A DC charger contains a converter which feeds the power directly to the battery, without the need for an onboard conversion. DC charging is more common at public charging stations, where time is limited.
