There are a number of different ways to charge your electric car’s battery pack. Being faced with normal and fast charging methods, and different connector types, can be a little daunting at first. But in fact it is much more straightforward than it first appears! In this short guide we’ll let you in on all the key information you need to know. Essentially, it comes down to two main considerations: WHERE you decide to charge and HOW FAST you decide to charge. These are interconnected, and the charging speed will depend on which particular EV you own, its battery capacity and what sort of charging system you are using. There are three categories or types of charging: Trickle Charge, AC Charge and DC Charge. 1. TRICKLE CHARGE The slowest method of charging your EV at home, using a standard (three-prong) 220V plug. It is only recommended in urgent cases, with caution and consultation with electricity providers. 2. AC CHARGE Having a wallbox installed lets you charge 3-4 faster using AC Household Charging. AC Public Charging is also available. 3. DC CHARGE The fastest way to charge your EV – at a public DC Fast charging station with power from 50kW and above. With this method you can top up your battery from 20 to 80% in approx. 40 minutes. There are also some ultra-fast charging stations that already provide more than 150kW.
