Geely EX5: 7 kW vs 11 kW Home Charging in the UK
Quick answer: The Geely EX5 supports an 11 kW onboard AC charger in the UK. A typical single-phase 7 kW wallbox can still be entirely adequate; 11 kW mainly benefits homes with a suitable three-phase supply and a reason to compress the charging window. Geely lists usable battery capacities of 60.22 and 68.39 kWh, so the value of 11 kW depends on which version you own and how much energy you need to replace overnight.
Start with the battery, then choose the wallbox
| EX5 battery reference | Usable capacity |
|---|---|
| Smaller pack | 60.22 kWh |
| Larger pack | 68.39 kWh |
Using a simple 90% wall-to-battery efficiency assumption for planning, a full 60.22 kWh refill would require roughly 66.9 kWh from the wall and the 68.39 kWh pack about 76.0 kWh. At 7 kW that is roughly 9.6 and 10.9 hours respectively; at 11 kW it is about 6.1 and 6.9 hours. These are calculated estimates, not Geely promises, and real sessions vary with battery temperature, voltage and charging losses.
Why many UK drivers will not need 11 kW
A typical UK house is single-phase, and many home installations are therefore built around a 7 kW wallbox. If the EX5 drives 35 miles and returns home for ten hours, the owner is replacing only the day’s energy, not the entire battery. Even a 7 kW unit has ample time to do that. The low-daily-mileage Level 2 guide shows why empty-to-full time often exaggerates the need for higher power.
Where three-phase 11 kW earns its keep
Eleven kilowatts becomes useful when the parking window is short, the car covers high daily mileage, or the household wants to concentrate charging in a narrow off-peak tariff period. It can also help a business or multi-driver household turn the car around more quickly between shifts. The important point is that 11 kW is a scheduling advantage, not a range upgrade: both wallboxes put the same energy into the same battery; one simply does it faster.
The tariff-window test
Take your cheapest overnight period and multiply its hours by the realistic wallbox power. A four-hour cheap window at 7 kW is 28 kWh from the wall before losses; at 11 kW it is 44 kWh. If your normal daily driving consumes 18 kWh, both options cover the day. If it consumes 38 kWh and you insist on charging only in that four-hour window, the 11 kW option becomes materially more useful.
Do not assume 11 kW because the car supports it
The electrical supply, consumer unit, existing loads and local installation requirements all come before wallbox output. Three-phase availability is not universal in UK homes and adding it can be far more expensive than accepting a slightly longer charging session. Compare load management versus service upgrade before treating a supply change as the default answer.
How DC charging changes the home decision
Geely also advertises up to 135 kW DC charging and around 20 minutes from 30% to 80% under suitable conditions. That gives owners a separate tool for exceptional high-mileage days. Home charging should be optimized for routine cost and convenience, while public DC exists for journey speed. Paying for a major domestic electrical upgrade solely to imitate road-trip charging is rarely the right framing.
A simple recommendation matrix
| Household pattern | Likely starting point |
|---|---|
| Single-phase home, long overnight parking | 7 kW |
| Three-phase already available, high daily mileage | 11 kW |
| Short cheap-tariff window and frequent deep refills | 11 kW can be valuable |
| Modest mileage, car parked all night | 7 kW is usually enough |
Bottom line
The EX5’s 11 kW onboard charger gives flexibility, but it does not make 7 kW inadequate. Match the wallbox to the energy you need to replace inside the hours you actually have. If 7 kW reliably reaches the departure target, the higher AC rating is capability you do not need to buy.
Treat UK single-phase and three-phase homes as two different use cases
The EX5’s 11 kW capability is most relevant where three-phase power is already present. For the majority of ordinary single-phase domestic installations, the decision is usually whether a 7 kW wallbox comfortably covers daily energy. Build the charging plan around the existing supply before considering a costly upgrade. If the house already has three-phase power for a workshop, heat pump or other equipment, 11 kW can be a low-friction benefit. If three-phase would need to be added solely for the car, the financial case needs to be much stronger.
Use the off-peak tariff as a capacity test
Suppose the cheap rate lasts five hours. A 7 kW charger can theoretically move up to 35 kWh from the wall during that period; 11 kW can move 55 kWh. Now compare those numbers with the actual weekday energy deficit. If the EX5 typically arrives needing only 18 kWh, both chargers finish inside the low-cost window. If high-mileage use regularly creates a 45 kWh deficit, 11 kW can shift much more of the refill into the discounted period. The tariff window converts charger speed into an annual cost variable.
Solar can reverse the usual “faster is better” logic
A household with rooftop solar may prefer slower daytime charging that follows surplus generation rather than a fast evening refill. If solar export is worth less than imported electricity costs, matching EVSE output to midday surplus can lower energy cost even when the vehicle supports 11 kW. Smart charging and load management can be more valuable than raw maximum power because they align the EX5 with the home energy system. The best charger setting can therefore change by season and time of day.
Installation success metric
After the first billing cycle, check how much EV energy was purchased at the intended tariff and how often the car failed to reach the morning target. If more than 95% of charging occurs in the preferred period and departures are consistently ready, the system is well sized. A higher charger rating would add capacity but not necessarily improve the metric. This is a simple way to stop charger selection from becoming a specification contest.
Home-charging conclusion
For the EX5, 11 kW is valuable when the property already supports it or when the shorter charging window creates measurable tariff or scheduling benefits. A 7 kW wallbox remains a serious, practical solution for typical overnight use. Let the house, tariff and mileage decide which capability matters.
Run a UK off-peak-window test before paying for 11 kW
Take the household’s cheapest overnight period and write down its exact length. A four-hour window at 7 kW can supply up to 28 kWh from the wall before losses, while 11 kW can supply up to 44 kWh. Now compare those amounts with the EX5’s real weekday deficit. If the car typically needs only 15–22 kWh, both rates finish inside the cheap window and 11 kW does not reduce energy cost. If the car regularly needs 35–40 kWh after a high-mileage day, the faster rate can move more of that refill into the discounted period and may have a measurable financial benefit.
Three-phase capability should already solve another property need
In many UK homes, adding or modifying three-phase supply is a much larger project than choosing a wallbox. If the property already has three-phase power for another reason, using the EX5’s 11 kW onboard capability can be straightforward. If it does not, calculate the charging benefit first and compare it with the cost and disruption of the electrical work. Saving two or three hours on rare deep refills is not automatically worth a major supply change when a 7 kW unit reaches the departure target every ordinary morning.
A two-EV household changes the answer again
If a second EV is likely, allocating available power intelligently may be more valuable than maximizing the EX5 alone. Dynamic load management can give one vehicle more power when the other is full, then redistribute capacity as household demand changes. This can preserve the existing service while increasing total overnight energy delivered to both vehicles. The design problem becomes “how many kWh must the garage deliver before morning?” rather than “how fast can the EX5 charge by itself?”
Use the larger battery only when it affects the schedule
The EX5’s two usable battery references differ by 8.17 kWh. On a 7 kW wallbox, replacing that extra amount takes a little over an hour before allowing for losses; on 11 kW it is less. That difference is modest compared with a full overnight parking window. Owners choosing the larger battery should therefore focus on range needs, while charger size should be based on daily energy and tariff timing. Battery capacity and EVSE power are related, but they solve different ownership problems.
Geely EX5 home-charging conclusion
A 7 kW installation is not a compromise simply because the EX5 can accept 11 kW. It is sufficient when it replaces the required energy inside the available parking and tariff window. Eleven kilowatts is valuable when high mileage, short parking, an existing three-phase supply or a narrow off-peak period creates a recurring need for faster recovery. Let the household schedule prove the need before paying for maximum AC capability.
