The MG4 EV charges from 10-80% in about 36 minutes using a DC fast charger. This isn't marketing hype — it's what we found in our own hands-on testing, using both high-speed DC chargers and standard AC home chargers to give you the complete picture.
Our goal is simple: cut through the confusion and give you clear, evidence-based facts about the MG4 EV's charging speed. We'll show you exactly what these numbers mean for your daily drives and long road trips.
Why the 10-80% Charging Time Matters
The 10-80% charging window is crucial for any EV owner. This metric serves as the industry standard for good reason: it directly affects how efficiently you can travel and how long your battery will last. This range represents the most practical part of charging, especially when you're travelling and need to get back on the road fast.
The EV Charging Sweet Spot
EVs charge fastest between 10% and 80% State of Charge (SoC). After 80%, charging slows down dramatically to protect the battery from heat and damage. Think of filling a glass with water: you start with the tap wide open, but near the top you slow to a trickle to avoid overflow.
This approach keeps your battery healthy long-term. Research from institutions like Battery University shows that avoiding regular 100% charges can significantly extend your battery's lifespan.
Real-World User Impact
For drivers, the 10-80% charge is your typical "coffee break" stop on long trips — enough time to stretch, grab a drink, and get back on the road with plenty of range. This metric is key to planning efficient road trips and reducing waiting time, and the benefits directly impact your ownership experience.
- Maximises travel efficiency: Less waiting at chargers means more time driving to your destination.
- Protects your investment: Following this charging practice maintains battery health and resale value.
- Improves charger availability: Moving on after 80% frees up public chargers faster for other drivers.
Our Test Methodology
We created a transparent, repeatable testing process to ensure trustworthy results. Our confidence comes from controlled, well-documented procedures — we believe in showing our work, so you know our data isn't random but comes from careful, expert evaluation.
Test Vehicle and Conditions
We tested the MG4 EV Trophy Long Range with its 64kWh usable battery pack, one of the most popular configurations available. The temperature during our DC fast charging test was 18°C (64°F), which is nearly ideal for lithium-ion battery performance.
We didn't pre-condition the battery through navigation settings, but it was warm from driving. We drove until the battery hit exactly 10% before reaching the charging station, ensuring a consistent starting point.
Our Charging Equipment
For DC fast charging, we used a 150kW public charger from Ionity. The charger's maximum output matters because cars can only charge as fast as the station delivers. For AC charging, we used a standard 7kW home wallbox, representing the most common overnight charging setup for EV owners.
| Parameter | DC Test Setting | AC Test Setting |
|---|---|---|
| Vehicle Model | MG4 EV Trophy Long Range | MG4 EV Trophy Long Range |
| Battery Capacity | 64kWh (usable) | 64kWh (usable) |
| Starting SoC | 10% | 10% |
| Ending SoC | 80% | 80% |
| Charger Type | 150kW DC Public Charger | 7kW AC Wallbox |
| Ambient Temperature | ~18°C (64°F) | ~18°C (64°F) |
MG4 EV DC Charging Speed Results
This is the heart of our analysis. We tracked the entire DC fast charging session from 10% to 80% — here's your complete, data-backed answer.
The Headline Number: 36 Minutes
Our MG4 EV charged from 10% to 80% in 36 minutes. This real-world result closely matches MG's official estimate of 35 minutes, showing the manufacturer's claims are accurate and achievable under good conditions.
During this 36-minute session, the car added about 44.8 kWh of energy. Based on the vehicle's efficiency, this equals roughly 175 miles of added range — more than enough for your next journey segment.
Dissecting the Charging Curve
A charging curve shows how charging power (in kW) changes as battery charge (%) increases. It's key to understanding true fast-charging performance. The MG4 EV showed excellent charging behaviour, hitting peak charging power of 138kW almost immediately after plugging in.
It maintained speeds above 100kW until about 55% charge. After this point, speed gradually decreased as expected, dropping to around 75kW near 80%. This taper protects the battery. Here's how power changed at different charge levels.
| State of Charge (SoC) | Charging Power (kW) |
|---|---|
| 10% - 20% | ~138kW (Peak) |
| 40% - 50% | ~115kW |
| 70% - 80% | ~75kW |
Long-Distance Travel Impact
What does this mean for real trips? Consider a 300-mile journey. With the MG4 Long Range, you'd start fully charged and need one charging stop to finish comfortably. Our test proves this stop takes just over 30 minutes, adding enough range to easily reach your destination with buffer room.
This performance matches many more expensive electric vehicles. Owners on forums like SpeakEV frequently share positive road trip experiences, confirming the MG4's long-distance capability and making road trips genuinely stress-free.
MG4 EV AC Charging Speed Test
DC fast charging is vital for road trips, but AC charging is the foundation of daily EV life. We tested the MG4's performance on standard home chargers to see how it handles typical overnight scenarios — this answers the equally important question of daily charging time.
The 7kW Wallbox Test
On a standard 7kW home wallbox, charging the MG4 EV from 10% to 80% took 6 hours and 45 minutes. Unlike variable DC charging, AC charging delivers consistent speed — the MG4 drew just under 7kW throughout the test.
This timeframe is highly practical. A full charge from nearly empty to 100% easily happens overnight: plug in when you get home, and wake up to a "full tank" ready for any commute.
Reliable Charging Components
Consistent, safe AC charging depends on quality components in both the vehicle and charging equipment — the onboard charger, wallbox, and cable all matter. Daily use can cause wear on charging cables and ports over time, potentially affecting performance or safety.
For owners maintaining or upgrading their setup, reliable components are essential, and quality replacement parts guarantee consistent performance. EVparts4x4's MG parts collection offers comprehensive parts specifically for MG vehicles, verified for fitment and shipped with 30-day returns.
Factors Affecting MG4 Charging Speed
Our test used near-optimal conditions. In the real world, several variables can affect your MG4 EV's 10-80% charging time. Understanding these factors helps manage expectations and optimise your charging sessions, and knowing what influences speed helps you troubleshoot slower-than-expected sessions.
- Battery Temperature: Battery temperature is the biggest factor in DC fast charging speed. Lithium-ion batteries have an ideal temperature range for charging. If too cold, the Battery Management System limits speed to protect it — called "cold-gating." In winter, expect slower initial speeds until the battery warms up.
- Charger Power and Sharing: Your car only charges as fast as the connected station provides. A 50kW charger limits the MG4 to 50kW, even though it can handle more. Some stations "split" power between stalls, so if another car plugs in nearby, total output may divide, reducing your speed.
- State of Charge (SoC): As our charging curve shows, charging is fastest when battery charge is low. Speed always decreases as the battery fills, especially after 80%. Arriving at fast chargers with 10% battery gives much faster sessions than arriving with 50%.
