Most fleet operators ask about EV batteries in terms of years: how long will it last, when will it need replacing. But the more useful question is a smaller one: what actually happens to the battery in your electric commercial van or truck on a normal Tuesday? The answer explains almost everything about long-term battery health, and it’s far less dramatic than most people expect.
A Day in the Life of an EV Battery
Picture a typical delivery van on a Singapore route. Here’s what its battery actually goes through in a single working day:
- Morning: the van leaves the depot at or near full charge, drawing steady power as it moves through traffic and stop-start deliveries.
- Through the day: every time the driver brakes, regenerative braking sends a small amount of energy back into the battery, offsetting some of the draw from acceleration and air-conditioning.
- Midday: on longer routes, a top-up charge may top the battery back up partway through the day, usually a short DC fast charge rather than a full charge.
- Evening: the van returns to the depot and charges overnight, usually on a slower AC charger, ready to leave at or near full charge again the next morning.
None of this is dramatic. A battery does not “feel” a hard day the way an engine does. It simply cycles through a narrow, well-managed range of charge and discharge, day after day, for years.
What Actually Wears a Battery Down Day to Day
Long-term battery capacity loss is driven by a handful of everyday factors, not by any single dramatic event:
- Heat: Singapore’s climate is tougher on batteries than a temperate one. Sustained high temperatures, especially combined with fast charging, accelerate chemical wear inside the cells faster than cooler conditions would.
- Frequent DC fast charging: fast charging is convenient, but it pushes more current into the battery in less time, generating more heat than a slow overnight AC charge. Occasional fast charging is fine; relying on it every single day adds up.
- Sitting at very high or very low charge: batteries left at 100% charge for long periods, or regularly run down close to empty, experience more stress than those kept in a moderate charge range.
- Heavy loads and hard acceleration: consistently maxing out payload or driving aggressively draws more current per trip, which adds marginally more daily wear than steady, well-loaded driving.
Individually, none of these factors matter much. It’s the accumulation over thousands of daily cycles, across years, that eventually shows up as the gradual capacity loss fleet operators plan around.
The Battery Management System Is Doing More Than You Think
Every modern commercial EV runs a battery management system (BMS) in the background, constantly working to protect the battery from the wear described above. The BMS regulates charging speed, manages heat through active cooling, and prevents the battery from actually reaching damaging extremes of charge, even if the dashboard shows “100%” or “0%”. In practice, this means day-to-day driving and charging habits matter far less than they did in early-generation EVs. Most of today’s commercial batteries, including the LFP cell-to-pack designs common across Skylink’s electric fleet, are built specifically to tolerate this kind of daily commercial cycling, with 3,000 or more charge cycles before meaningful capacity loss.
Why Lithium Iron Phosphate (LFP) Batteries Handle Daily Use So Well
Lithium iron phosphate (LFP) is one of the most common battery chemistries across Skylink’s electric fleet, powering models like the BYD T35 with its Blade Battery technology. Not every vehicle in the fleet uses it, since battery chemistry varies by manufacturer and model, but where it’s used, it’s a big part of why the daily wear-and-tear factors above matter less than fleet operators expect.
- Thermal stability: the iron phosphate cathode is chemically more stable under heat than older nickel-based lithium-ion chemistries, which matters in Singapore’s climate where sustained high temperatures are a daily reality, not an occasional stress test.
- Tolerates full charges: unlike some other lithium-ion chemistries that degrade faster when regularly charged to 100%, LFP cells are generally fine being charged fully overnight, which suits the depot charging pattern most delivery fleets already use.
- High cycle life: LFP cells typically handle 3,000 to 6,000 or more full charge cycles before dropping below 80% capacity, among the highest cycle life of any commercial battery chemistry on the market today, well suited to daily commercial cycling.
- No nickel or cobalt: LFP cells use iron and phosphate instead, which removes two of the more heat-sensitive and costlier materials found in other battery chemistries, and has helped LFP pass severe abuse tests such as nail penetration and multi-tonne crush tests without combusting.
The trade-off is that LFP packs are slightly heavier per kilowatt-hour than nickel-based alternatives, meaning marginally less range for the same battery size. For last-mile and delivery routes, where usable daily range matters more than maximum range, that trade-off rarely shows up in practice. Whichever chemistry sits inside a given van or truck, Skylink matches the vehicle’s charging and servicing schedule to what that battery actually needs, so daily wear and tear is managed correctly either way.
Why the Daily Wear and Tear Isn’t Your Problem to Manage
If tracking charge habits, heat exposure and daily cycling sounds like more than your business wants to manage, it doesn’t have to. When you lease an electric commercial vehicle from Skylink, the vehicle is monitored and serviced by our in-house workshop team throughout the lease. Battery health checks, servicing and any issues that come up are handled on our side, not yours.
That means your drivers can focus on the route, not the charge screen, and your business gets the benefit of a well-managed battery without needing to build charging protocols of your own.
Explore Skylink’s electric van and truck leasing range to find a model that matches your route and payload, with range options from around 268km up to 489km per charge across the lineup.
Also note: since June 2026, Class 3 and Class 3A licence holders in Singapore can already operate electric light goods vehicles up to 3,000kg. We covered the new Class 3 licence changes here in full.

When you lease an EV from Skylink, day-to-day battery care comes included. No charging schedules to manage. No heat-related wear to track. Just a vehicle that’s ready every morning. |
The Bottom Line
What really happens to your EV battery every day is, mostly, nothing dramatic. A steady cycle of charge, drive, brake, and charge again, quietly managed by a battery management system built for exactly this kind of use. It’s the accumulation of thousands of ordinary days, not any single bad one, that determines how a battery ages.
And if you lease rather than buy, you don’t need to think about any of it. That’s someone else’s job.
