EV Charging Explained: Everything Hertfordshire Drivers Need to Know

Whether you’re a new EV owner or considering making the leap, understanding how to charge your car at home is key to getting the most out of your vehicle. In this guide, we’ll break down everything you need to know about EV charging (no jargon, just clear advice from your local trusted electricians).

1. The Basics of EV Charging

At its core, EV charging is simply supplying your car’s battery with electricity. But the speed and convenience depend on the type of charger you use.

• 3-Pin Plug Charging (Slow Charging):  Uses a standard household socket. Handy in emergencies but takes 20+ hours to fully charge most EVs. Not recommended long-term.

• Home Wallbox Charger (Fast Charging):  The most popular option for homeowners. A 7kW charger can fully charge most EVs in 6–8 hours, making it ideal for overnight charging.

• Public Rapid Chargers:  Found at motorway services and some petrol stations. With 22kW–150kW power, these can add 80% charge in 30–60 minutes. Perfect for long journeys.


2. EV Connectors Explained

One source of confusion for many drivers is the type of charging connector their EV uses. Here’s a quick breakdown:

• Type 2 Connector (Most Common in the UK):  Standard for newer EVs. Used for both home and public charging.

• Type 1 Connector:  Found on some older EVs. Less common now but still in use.

• CHAdeMO & CCS (Rapid Charging):  Used for ultra-fast charging at public stations.


👉 At JJB Electrical, we always ensure your charger is compatible with your vehicle’s connector type.

3. Myths About EV Charging (Busted!)

• Myth 1: Charging an EV is complicated.  ✅ Truth: With a dedicated home charger, it’s as simple as plugging in your phone.
• Myth 2: EVs take forever to charge.  ✅ Truth: Overnight charging at home means you wake up with a “full tank” every day.
• Myth 3: EV chargers use loads of electricity.  ✅ Truth: Smart chargers let you schedule charging during off-peak hours, saving money and reducing strain on the grid.
• Myth 4: Home charging isn’t safe.  ✅ Truth: Professionally installed chargers are designed with multiple safety protections. JJB Electrical installs only NAPIT-approved and fully compliant systems.

4. Smart Charging – The Future of EV Ownership

Smart chargers are becoming the go-to choice for homeowners. Here’s why:

📱 App Control: Start/stop charging from your phone.


💰 Cost Savings: Automatically charge during cheap overnight tariffs.


🌍 Eco-Friendly: Integrates with solar panels and home batteries for greener charging.


🔒 Enhanced Safety: Built-in fault detection and surge protection.


Imagine never worrying about petrol prices again (just plug in at night, and you’re ready to go in the morning).

5. Tips for First-Time EV Owners

• Install a dedicated home charger early. It’s safer, faster, and more convenient than relying on a 3-pin plug.

• Check your fuse board. Older consumer units may need an upgrade to handle the additional load safely.

• Plan your journeys. While home charging covers daily needs, know where rapid chargers are for longer trips.

• Keep cables tidy. Invest in cable hooks or reels to avoid trip hazards.
