MG4 Charging Time: The Complete, No-Nonsense Guide for Every MG4 Owner

Understanding the Real Meaning Behind MG4 Charging Time

When we talk about MG4 charging time, we’re not just chasing a number—we’re chasing convenience, strategy, and the everyday practicality of living with an electric hatchback. We know how frustrating it is when official figures don’t match real-world experiences, so in this guide, we explore the MG4’s true charging times from every angle: home chargers, rapid chargers, long-distance planning, battery behaviour, and even how weather impacts things.

Our aim? To give you the clearest, most human, most experience-based breakdown of MG4 charging time anywhere on the internet.

How MG4 Charging Time Actually Works

Before diving into speeds and durations, we need to understand what shapes charging time:

• Battery capacity
• State of charge (SoC)
• Ambient temperature
• Type of charger (AC vs DC)
• BMS behaviour and tapering
• Which MG4 variant you own

These elements interact like ingredients in a recipe—change one, and the whole flavour shifts.

MG4 Battery Variants and Their Charging Behaviour

The MG4 lineup has multiple battery sizes, each with its own charging personality. That means charging time is never one-size-fits-all.

MG4 Standard Range (51 kWh)

• Max AC charging: 6.6 kW
• Max DC charging: ~117 kW peak
• Typical 10–80% DC time: ~35 minutes

MG4 Long Range (64 kWh)

• Max AC charging: 7 kW
• Max DC charging: ~135 kW peak
• Typical 10–80% DC time: 35–38 minutes

MG4 Trophy / Trophy Long Range

• Same battery as above, same charging performance
• Added extras may affect weight, not charging speed

MG4 XPower

• Dual-motor, same 64 kWh pack
• Slightly different temperature management
• 10–80% DC: ~30–35 minutes in ideal conditions

Each variant uses MG’s LFP or NMC chemistry, and the MG4’s BMS controls how fast electrons flow into the pack.

Understanding AC vs DC: Two Worlds, Two Charging Times

AC Charging (Home or Public Slow Charging)

This is the everyday “plug in at night and forget about it” method.

• Predictable
• Battery-friendly
• Slower

DC Charging (Rapid & Ultra-Rapid)

This is the “coffee break and go” method.

• Fast
• Ideal for road trips
• Sensitive to temperature and SoC

Let’s break them down properly.

MG4 AC Charging Time (Home Charging)

Why AC Charging Is the Backbone of EV Ownership

We often treat rapid charging as the star of the show, but AC charging is the quiet hero—consistent, cheap, and kind to the battery.

MG4 AC Charging Speeds by Charger Type

3-Pin UK Plug (2.3 kW) – The Slow Emergency Hero

• 0–100%: 20–26 hours
• Only for emergencies or overnight trickle charging

7 kW Home Charger – The Gold Standard

• Standard Range (51 kWh): 7.5 hours
• Long Range (64 kWh): 9 hours
• XPower: ~9 hours

This is the MG4’s sweet spot: slow enough to preserve battery health, fast enough to charge fully overnight.

22 kW AC Charger

The MG4 cannot accept more than 6.6–7 kW AC despite being plugged into a 22 kW charger.

• Actual AC limit: ~7 kW

So while the charger is fast, the car remains the limiting factor.

MG4 DC Fast Charging Time (Rapid & Ultra-Rapid)

Conditions Must Be Right

DC charging isn’t magic. The MG4 delivers impressive numbers, but only when the planets align:

MG4 Towing Capacity: The Complete Expert Guide for Safe, Legal & Efficient Towing

• Warm battery
• Low state of charge
• High-power charger
• Battery preconditioning (for XPower and latest software)

MG4 Peak Charging Numbers

• Standard Range: ~117 kW peak
• Long Range / Trophy: ~135 kW peak
• XPower: ~140 kW+ peak in ideal conditions

Remember: peak ≠ sustained. Charging curves taper off sharply after 60–70%.

Real-World DC Charging Times for the MG4

10–80% (Most Common Metric)

• Standard Range: 32–35 minutes
• Long Range: 34–38 minutes
• XPower: 30–35 minutes

20–80%

• Add only ~1–2 minutes less
• EVs charge fastest when low

80–100%

The slowest part.

• 20–40 minutes extra
• Not recommended unless you absolutely need the range

Charging slows dramatically to protect the battery.

MG4 Charging Time in Cold Weather

Ah yes—the winter EV myth. Let’s confront it head-on.

What Really Happens in Cold Climates

When temperatures drop:

• The BMS limits power
• Chemical reaction slows
• Charging speed drops noticeably
• AC charging remains stable
• Preconditioning becomes essential on DC

Typical Winter DC Charging Time

• 10–80%: often 45–55 minutes
• Extreme cold → even slower

Winter Tip

Precondition the battery by:

• Navigating to a rapid charger in MG iSmart
• Driving at motorway speeds before arriving
• Avoiding long overnight cold-soak before rapid charging

MG4 Charging Time and Battery Health

Here’s where we talk long-term ownership.

What Slows Charging Over the Years

• Battery degradation
• Thermal cycling
• DC charging frequency
• High SoC storage
• Extreme heat/cold exposure

How to Protect the MG4 Battery

• Keep daily SoC between 20%–80%
• Prefer AC charging
• Avoid repeated rapid charging
• Use preconditioning in winter
• Don’t store at 100%

Your future self (and your resale value) will thank you.

MG4 Charging Curve Explained

Imagine charging is like filling a glass:

• At first, you can pour quickly
• As the glass fills, you pour slower to avoid spilling

That’s the MG4 charging curve.

The Three Phases

Phase 1 – Ramp-Up (0–10%)

Fast rise to peak.

Phase 2 – Peak Zone (10–55%)

Highest sustained charging speeds.

Phase 3 – Tapering (55–100%)

Charging slows dramatically.

This is why 80–100% takes longer than 10–60%.

Tips to Speed Up MG4 Charging Time

Here’s the practical, everyday wisdom we all wish we knew on day one.

The “Do” List

• Precondition before rapid charging
• Charge when the battery is warm
• Prefer <50% SoC for rapid sessions
• Unplug at 80% unless needed
• Plan chargers along warm battery routes

The “Avoid” List

• Charging from 80–100% on DC
• Rapid chargers after long cold-soaks
• Repeated rapid charging sessions
• Storing at 100%

How Charging Time Varies Between MG4 Trims

Some trims have slightly different behaviour:

Standard Range

• Smaller battery → faster full charge
• Lower peak → still efficient range-to-time ratio

Long Range

• Larger battery → longer full AC time
• Faster DC peak → shorter rapid sessions

XPower

• Slightly more aggressive thermal control
• Typically the fastest to charge from low SoC

MG4 Charging Costs vs Charging Time

Time and money are connected.

Home Charging (7 kW)

• Cheap
• Predictable
• ~£6–£10 full charge depending on tariff

Public AC

• ~25–40p/kWh
• Best for top-ups

DC Rapid

• ~55–79p/kWh
• Good for speed
• Not for daily use

Ultra-Rapid (150 kW+)

• Often the most expensive
• MG4 can’t always take full power due to tapering
