How Does Fast Charging Affect Battery Health

New VinFast App for iPhone and Android Smart Phone

New VinFast VF8 ChargingA battery is a battery, whether it’s in your phone, a camera, or a car. Like every other piece of technology, batteries will slowly degrade over time. It’s perfectly normal and natural. However, there are things you can do to mitigate battery degradation in devices. While it is rare, sometimes batteries can lose some of their abilities more quickly, which is why VinFast has the best battery warranty in the business with its 10-year, unlimited-mile warranty.

Learning How to Charge

Remember back in the day when cell phones were first coming out? It was recommended to charge them to full, then let them fully discharge on their own, and then from there, you could use them as normal. Well, now, especially with lithium-ion batteries in EVs and smartphones, it is recommended that batteries always charge between 20% and 80% most of the time. This is why car manufacturers like VinFast tell you the charging speed is between 20% and 70 or 80%.

It can be tricky to know the best practices because, simply put, you are just trying to live your life and drive your car as you need to. One thing people are starting to ask is how much your VinFast is affected by charging the car via a Level 3 DC fast charger. That charger carries the most kilowatts to charge cars more quickly. In the case of a VF8 or VF9, that’s about 25 minutes to get you up to 70%. But does it hurt your battery life? Well, yes… kind of. Should you worry about it? That depends.

Where is it Best to Charge?

No matter what, it is always easiest and cheapest to charge at home. So, say you use 50% of your battery range by driving to and from work every day. When you plug into your home charger, which hopefully is a VinFast Home charger, the car and the charger will communicate. This will get you up to 80% at a reasonable rate and then relax the charge on its way up to 100% so as not to put too much strain on the battery. It is important to note that your EV is very smart and works hard to protect the battery system in your car.

Luckily for EV owners, some studies show that using fast chargers can have negligible degradation effects over time. That being said, if you do lots of long-distance traveling and utilize Level 3 chargers, not only will you be spending more money to charge your car, but over time, this could contribute to your battery health dwindling from 100% of capacity down to 90 or so percent after a couple of years of doing this. That means that your maximum range will drop by 10%.

When In Doubt, Charge at Home

There is still plenty of testing to be done to determine how batteries will last over time when charged more quickly and subjected to heat and stress. This is why it’s always best to charge your VinFast at home as much as possible.

Should I Always Charge My EV at Night?

VinFast Charging at Home

VinFast Charging at HomeThere are many questions new electric vehicle owners have. It’s kind of like having your first baby—although it’s nothing like having a baby, except in the sense that you wonder if you’re doing anything wrong, given you’re in an unfamiliar position. A question experts get asked all the time is when is it best to charge your VinFast EV? While it seems like a no-brainer to say at night, that answer is changing slightly in the current charging landscape. Thanks to new studies and information from companies like Recurrent Auto, we have more information than ever about charging and EV battery health.

Charging your VinFast at night is, in most cases, a logical answer to when you should charge your car. Fewer items in your home are bogging down the grid. While you may be running your dishwasher at night, it’s rare that you’re also running your washing machine and the dryer, all while charging your car while you are sleeping. This means that energy costs and usages are typically much lower, as even your AC or heating system isn’t running as often or as hard, in most cases. However, it should be noted that energy companies could, at some point, start pricing their energy higher due to more demand at supposed off-peak hours around or after midnight.

With that being said, there are states, like California, that utilize and take advantage of solar energy during the daytime when the sun is out and about up in the sky. This window is between 10 am and 4 pm. These would be optimal times to charge a car, as the grid is emitting less carbon dioxide (CO2) and various greenhouse gases. Instead, it’s being charged more naturally by the carbon-neutral sun. According to Recurrent, though, in California only about 25% of all EV charging occurs during 10 am to 4 pm.

Now what happens if there are multiple EVs in your neighborhood that are all plugged in overnight? Well, believe it or not, the meter attached to your house is pretty intelligent. Most meters attached to houses are now called AMRs, or Automated Meter Readers, which send all your power and energy usage digitally to the energy provider. With the switch to digital, that means the meters and the grid as a whole can monitor things more closely. For instance, if you have a dozen cars on one street that are all plugged in to charge overnight, the meters and overall grid communicate with one another. They know the energy/charging needs of each car and can appropriately choose which vehicles to charge first. The systems also know when you typically plug your car in to charge and when you unplug your car. So, it will attempt to charge your car to 100% before the usual time that you unplug your car to leave.

What is the answer? Well, home EV chargers can be set to charge to full by a certain time manually via the actual charger or by the app on your smartphone. If you leave for work at 7 am, then you’ll want to make sure your charger knows this and to tell it that you don’t care when your car gets charged, so long as it’s topped up to 100% by 7 am. Some utility companies offer users the ability to tell them when to charge your car, and some companies are working together to develop even smarter home charging systems that can learn when charging is cheapest, as well as automatically charge from renewable energy sources, whether from your house or the grid.  

Things Are Changing Quickly for the Better 

The EV industry is changing rapidly, bringing new questions and added solutions. For now, it’s best to plug your car in nightly at home and to tell the charger when you need your VinFast to be fully charged.
