What are the different levels of EV charging?

There are three main levels: Level 1 (slow, from a standard wall socket), Level 2 (fast, the standard for home/workplace wallboxes), and Level 3 (rapid DC charging, found at public stations for long trips).

What's the difference between CCS, NACS, and Type 2 connectors?

Type 2 is the standard for AC charging in the UK/EU. CCS is the standard for DC fast charging in the UK/EU and widely in the US. NACS is Tesla's connector, which is becoming the new standard for most brands in North America from 2025 onwards.

How much can I save by charging at home?

Home charging is significantly cheaper than public charging. By using a special overnight (off-peak) tariff, you can often charge your EV for 70-80% less than the standard electricity rate, making your per-mile cost a fraction of petrol.

EV charging has three levels: Level 1 (slow), Level 2 (standard for home), and Level 3 (public fast charging). Connectors are standardizing to CCS in the UK/EU and NACS in the US. Home charging is the cheapest method, especially with off-peak tariffs, while public fast charging is the most expensive but necessary for long trips.
