MG4 Charging Speed: The Complete Real-World Guide

Understanding Why MG4 Charging Speed Matters

When we talk about EV ownership, charging speed is the heartbeat of the whole experience. We’ve all been there—standing by a charger, staring at the percentage like we’re waiting for toast to pop. The MG4, with its clever engineering and impressive tech-to-price ratio, brings charging capabilities that punch well above its weight. But how fast is it really? And more importantly—how fast is it for you, in the real world?

In this guide, we break it down with clear examples, simple metaphors, and straightforward explanations. Think of it as having a friend walk you through everything that matters: AC speeds, DC speeds, battery options, charging curves, home-charging tips, and how to squeeze every last drop of efficiency out of your MG4’s electrons.

MG4 Charging Basics

Before diving into numbers and charts, we need to understand the foundations. Charging an MG4 can feel like learning a new language at first, but once the basics click, the entire EV experience becomes second nature.

AC vs DC: What’s the Big Difference?

• AC Charging (Slower)
  This is what you get at home chargers and most public destination chargers. The MG4’s onboard charger dictates the maximum power intake.
• DC Charging (Faster)
  Also known as rapid or ultra-rapid charging. This bypasses the onboard charger and feeds the battery directly with DC—meaning much faster speeds.

Battery Size Determines Charging Speed

The MG4 has:

• A 51 kWh Standard Range battery, and
• A 64 kWh Long Range battery.

Both support different peak speeds and have different charging curves. Like humans: some people chug water fast, others sip slowly.

MG4 AC Charging Speeds

The MG4 offers impressive AC speeds for its class.

MG4 Standard Range (51 kWh) AC Specs

• Up to 6.6 kW AC
• Typical home wallbox: 7 kW (so you max it out)

MG4 Long Range (64 kWh) AC Specs

• Up to 11 kW AC (three-phase)
• On 7 kW single-phase (most homes in the UK):
  Expect ~7 kW charging, same as the Standard Range.

How Long Does AC Charging Take?

Approximate 0–100% times:

Is it slow? Not at all—it’s perfect for overnight charging. You plug it in, you sleep, and you wake up with a "full tank."

MG4 DC Charging Speed: The Real Magic

Here’s where the MG4 shines. For its price point, the DC charging performance is shockingly competitive.

MG4 Standard Range (51 kWh) DC Specs

• Peak: up to 117 kW
• 10–80%: approx. 35 minutes

MG4 Long Range (64 kWh) DC Specs

• Peak: up to 135 kW
• 10–80%: approx. 34 minutes

We’re talking speeds that rival EVs costing twice as much.

Understanding the MG4 Charging Curve

Charging curves are like running: anyone can sprint for 10 seconds, but maintaining that pace is the real challenge. EV batteries behave the same way.

The MG4’s Curve Has Three Stages

Stage 1 — Rapid Ramp-Up (10%–30%)

This is the “espresso shot” stage. The MG4 quickly climbs to its peak charging power.

Stage 2 — Stable Plateau (30%–55%)

The battery sustains high speeds surprisingly well—especially the Long Range variant.

Stage 3 — Tapering Off (55%–80%)

Here it slows down to protect battery health.

Why 10–80% Is the Sweet Spot

Charging from 80–100% can feel like the last 10% of uploading a YouTube video—it drags.
That’s why most EV drivers aim for 10–80% on long trips.

Real-World Charging Times (Tested Scenarios)

Let’s look at real scenarios rather than perfect lab conditions.

Scenario 1: Winter Rapid Charge (5°C)

• Time to 80%: 5–7 minutes slower
• Peak power: drops by 15–20 kW

Cold batteries are like cold humans—they need time to “wake up.”

Scenario 2: Warm Battery, Good Rapid Charger

• Hits peak charging more quickly
• Maintains 120–135 kW longer
• 10–80% often below stated times

Scenario 3: Low-Power Rapid Charger (50 kW)

• The car can only take what the charger gives
• MG4 will max out the 50 kW quickly
• 10–80%: 55–65 minutes

Preconditioning: The Secret Weapon

The MG4 supports charging preconditioning when navigating to a charger via built-in navigation.

Why Preconditioning Matters

• Warms battery
• Improves peak speeds
• Reduces time to reach optimal charging
• Prevents cold-battery slowdowns

It’s like stretching before going for a run—you perform better overall.

Maximising Charging Speed: Our Practical Tips

If you want to get every ounce of performance from your MG4’s charging system, follow these simple hacks.

Keep Battery Between 10–60% During Road Trips

This is the sweet spot for maximum charging efficiency.

Avoid Arriving With a Cold Battery

• Drive 15–20 minutes before stopping
• Use preconditioning for DC charging

Know When to Stop Charging

After 80%, the speed slows drastically.
It’s usually better to unplug and hop to the next charger.

Use the Right Chargers

• For fast stops: 100–150 kW chargers
• For long breaks: even 50 kW chargers work
• For home: 7 kW wallbox

MG4 Charging Costs Explained

Charging speed’s great and all—but what about money?

Home Charging Costs

• Typical UK rate: 29–34p/kWh
• Off-peak tariffs can go as low as 7–12p/kWh

Rapid Charging Costs

• Typical price: 65–79p/kWh
• Ionity/Ultra-fast: ~85p/kWh
• Tesco Pod Point: ~60p/kWh

Cost From 10–80%

Charging speed impacts how long you wait; charging cost impacts how often you pay.

How MG4 Charging Speed Compares to Rivals

This is where the MG4 flexes.

Vs VW ID.3

• ID.3 Peak: 100–120 kW
• MG4 Peak: 117–135 kW

MG4 wins on speed and price.

Vs Renault Megane E-Tech

• Megane Peak: 130–137 kW
• MG4 Peak: 117–135 kW

Almost neck-and-neck.

Vs Kia Niro EV

• Niro Peak: 70 kW
• MG4: MUCH faster

MG4 dominates.

MG4 Charging Speed in Long-Term Ownership

Charging performance isn’t only about today—it’s about the next five years.

Battery Longevity

MG uses:

• LFP cells (51 kWh): extremely durable
• NMC cells (64 kWh): energy-dense and refined

Both are designed for minimal degradation.

After 3 Years of Use

Expect:

• 6–10% capacity loss (normal)
• Charging peaks remain mostly unchanged
• Real-world speeds still strong

The MG4’s battery management system is surprisingly refined for its segment.

Charging Speed Myths We Should Clear Up

This is where misinformation runs wild. Let’s bust a few myths.

Myth 1: “Faster Charging Damages Your Battery.”

Truth:
Using DC chargers regularly is fine thanks to modern thermal management. Abuse comes from constant 100% charging, not fast charging.

Myth 2: “AC Charging Is Always Better.”

Truth:
Better for overnight? Yes.
Better for battery health? Not necessarily.
The MG4 is designed for both.

Myth 3: “Cold Weather Makes Charging Impossible.”

Truth:
It just slows it down—unless you precondition.

MG4 Rapid Charging: A Step-by-Step Guide

A simple workflow to ensure the fastest possible charge.

1. Set Destination → Charger (to precondition)

The car prepares the battery on the way.

2. Arrive Between 10–20%

This hits the optimal curve.

3. Plug In and Start Session

Avoid chargers with shared power cabinets if possible.

4. Watch the Peak

Within 2–3 minutes, your MG4 should climb to 100–135 kW.

5. Unplug at 80%

Unless you need the range.

How Weather Impacts MG4 Charging Speed

Like humans, batteries have "moods" affected by weather.

Cold Weather (-5°C to 5°C)

• 20–30% slower
• Peak speeds may stay below 100 kW
• Preconditioning is essential

Mild Weather (10–20°C)

• Perfect conditions
• Full peak speeds
• Fastest charging times

Hot Weather (30°C+)

• Battery cooling activates
• Slight throttling may occur
• Still significantly fast
