Should I Charge My Electric Car Every Night Part 2?
I have already provided some great information on Should I charge my electric car every night previously if you have not read that then I would highly suggest you to go thru it so that you can understand this article better.
Topic: Should I Charge My Electric Car Every Night
Electric cars force us to rethink our driving habits. For decades, we have always planned our handling on intermittent gas station visits to make sure our tanks stay full, and we can continue on our way. Although gas tank sizes vary, the average 2020 sedan ranges around 400 miles on a single gas tank. On the other hand, electric vehicles can only give us a better range of about 316 miles on a single charge (Tesla Model Y). So should you recharge every night?
In general, yes, you should charge your electric car every night if you drive a lot – it will not affect the car battery as people fear. But night charging is not for everyone.
Why do some people feel the need to charge an electric vehicle every day?
If you have an electric car that you use every day, you might be wondering if you can charge it every night. It may damage the battery; it will not charge properly due to overcharging. I know you are concerned about damaging the battery if you let it continue to charge once it is full.
Do you have to charge your electric car battery every night? Yes, you need to charge it every night if you used it during the day. They are calibrated to slow down the charging process when they are about to be fully charged. There is no need to worry about overloading them.
Many of our everyday electronic devices do not require a daily charge, especially when we are not constantly using them. The truth is, there is nothing that different about the electric car, and yet it is still common to see people plug in the car to charge it even after the vehicle has only been used for one. A handful of short trips totaling maybe 30 miles in total.
The first reason for this is probably a phenomenon known as “distance anxiety.” Even though your gasoline car has a specific range capable of while driving, we seem to be more aware of our electric car’s range. Electric vehicle drivers naturally want to keep their cars at full range if they need to take a more extended trip one day. This means recharging to the max every night when parking.
Another reason is that electric cars have a shorter range than our gasoline cars at the current level of technology, and the likelihood of being stuck without the ability to refuel is higher than that of gasoline-powered cars. After all, you can’t load electricity into a convenient gas can and walk back to your car.
Is it dangerous for the battery to leave your electric car plugged in overnight?
Some people think that they could damage their electric car battery if they constantly charge it overnight. I can understand this fear as it will almost reach its full capacity every night, affecting battery performance.
However, it is extremely difficult to damage a battery simply by charging it. The major manufacturers have made sure that it is practically impossible to overcharge the battery. They programmed their vehicles through a battery management system to slow down charging once the battery was charged to a certain level.
How exactly does this battery system that prevents battery overcharging work?
- Once the battery is close to a 100% charge level, the monitor will significantly reduce the charge rate. This reduced fee is called a maintenance charge.
- The battery will charge slowly at a rate equal to the discharge rate so that the battery is not overcharged.
Does fast charging the electric battery at home harm it?
Quickly recharging the battery of an electric car saves us a lot of time. However, will it cause damage to the battery due to the voltage applied to it? Also, if you end up damaging the battery, will the warranty be voided due to your lack of judgment?
Level 2 charging is of course faster, but it won’t damage the battery. If you are installing a battery that charges at level 3 (highly unlikely due to the cost involved), you may need to worry.
Is there a downside to recharging every night?
Based on the reasons given above, you can agree that it makes sense to keep your electric car fully charged every night. On the other hand, you should be aware of the possible downside to this regular charging cycle, especially if you try to keep the battery at 100%. Trying to keep the car 100% charged every day could lead to battery drain, as can repeatedly letting it discharge to zero and then fully recharging it.
Your electric vehicle battery is robust and designed to hold its charge for thousands upon thousands of charge cycles. Consumer group Green Energy Consumers noted on its blog that data collected from 6,000 vehicles shows that the average battery for electric cars only loses about 2.3% of range each year due to normal wear and tear. Assuming your EV has a range of around 250 miles, that’s only 4 miles per year. It varies from car to car but is an industry average.
Given that the average driver in the United States (based on 2015 data) drives about 29.2 miles per day, even the lower end of the EV range spectrum can drive a few days without charging at all. Therefore, it is safe for most drivers to keep the battery at 70-80% charged, and you can do this by setting its maximum charge level on your car and charger. This brings us perfectly to the next question.
- If you own or want to own a Tesla, you need to consider whether or not you should charge it every night. It won’t harm your battery if you do unless you allow it to charge 100% every night.
- There is a way to set the maximum charge level to 90%, which the manual recommends. The strange thing about the Tesla manual is that it doesn’t seem to mention how often it can be charged, so I guess frequency isn’t an issue, or they would have mentioned it.
- Tesla manuals even mention that you should charge as often as possible to never be in a situation where your charge is too low. Heard people charging even after driving to a grocery store that required a 3-mile drive.
So, in other words, charge it every night, but never 100%. Over time, you will find out if a lower load is fine for you based on your average daily mileage, but the range is high enough that you are okay with reducing the maximum amount of load.
In addition to setting a maximum charge level for your Tesla, you should try to set the timer to charge about 1 hour before using it in the morning. This charge before use will heat the battery. A hot battery will not use battery power to heat itself, and you can then take full advantage of the benefits of regenerative braking.
Even if you end up accidentally charging 100% when charging overnight without setting a limit, I don’t think you’re going to damage the battery.
Tesla realizes that some customers will attempt to fully charge and have programmed the battery to slow down once the level is around 90%. It will only charge at a rate that matches the rate at which the battery depletes its charge level. In other words, the on-board computer will protect the battery from overcharging.
Another reason to charge your Tesla overnight is that you are advised never to let the battery drain below the 10% level. It is recommended for general lithium batteries.
Even Elon Musk said on Twitter that the best upload range is between 30 and 80 percent. The best way to maintain this level is to plug it in every night and set the upper level at around 80-90 percent.
Are there any benefits to the daily charging of electric vehicles?
The first and most obvious benefit is that it maintains enough charge for daily battery life to meet your needs as they arise. The added benefit of electric cars is that you have tight control over the amount of payment you receive each day, which means you can enjoy the benefits of an optimally charged car every day without the wear and tear that can result from charging Overload.
Another advantage of daily charging at home is that it avoids the need for public fast-charging stations. Fast DC charging is a unique solution to the problem of charging time. Today’s fastest drives can deliver an incredible 350 kW charging power, providing a 100-mile range in less than 10 minutes. Unfortunately, hardly any car on the market today is designed to accept this type of entry, but some future models like the 2022 Hummer EV will handle it.
Suppose your car can handle up to 50 kW, which is still much more than the average home charging configuration. Reaching or exceeding this level daily would cause more battery drain. Using a slower trickle charge at home allows you to maintain range while the battery retains its power and output capacity over time.
Finally, the daily recharge has economic advantages. Average data shows that the cost per mile for electric charging is only $ 0.04, while the average gas-powered sedan costs about $ 0.46-0.60 per mile. Your daily charge, while intuitively too expensive to use all that electricity every day, actually ensures you spend less per year n your car.
Charge level at home to maximize the possible cycles of your electric car battery:
If you are charging your electric vehicle at home, you need to know the correct charge level that will allow the most charge cycles. Charge cycles are the number of times you will be able to charge the battery.
I remember buying rechargeable batteries that said they could be charged 100 times in total. It’s the same principle with the lithium battery packs that make up most electric car battery packs. There is a limit on the number of charges, the batteries will not last forever.
If you’re not worried about your battery, you may be the kind of person who delays charging the battery and ends up at zero before recharging. Or maybe you leave it plugged in without setting the upper limit to just 90%.
I’ve searched online to find out which levels seem to work best to get the most charge cycles for an EV battery; refer to the following table:
|Charge Level in Percentages (upper and lower limits
|Cycles before the capacity is reduced to 90 percent
It is evident from the graph above that keeping the charge level at 80-70 percent is best for the number of cycles. It is possible to do this, especially if you charge at home every night and set the upper limit to 80%.
Personally, I’d be fine with the 80-30 charge level, as it reflects more of the average daily usage for most drivers.
Why charging at night could be more harmful to the environment?
Since many of us buy electric vehicles to reduce the negative effect on the environment, you should be aware that charging your battery has an indirect negative impact on the environment.
When you charge your electric car every night, you are using electricity produced in power plants. Power plants generate electricity from carbon-free or low-carbon sources such as nuclear reactors, sun, wind, and water.
However, some power plants burn fossil fuels to generate electricity. For example, some power plants burn coal to generate electricity. The higher the electricity demand, the greater the probability of a negative impact on the environment.
It’s good that the company is trying to phase out gasoline cars to drive electric cars, but we do consider power generation.
Most Americans think of electricity as green energy. The electricity produced in California is primarily green. The average electric car will create 100 grams of greenhouse gases per mile if it uses the electricity that is produced in California.
The Midwest and the southern United States generate electricity from coal, which releases CO2 into the environment when it is burned. Below is a comparison of the greenhouse gases created by electric cars according to the type of electricity production used:
|Midwest and Southern Part of the States
|Carbon level of electricity production
|Relatively high, due to the likelihood of burning coal.
|Greenhouse gas production per mile per electric car using the electricity produced
The final recommendation on the daily charging of electric vehicles: yes or no?
The short answer “Yes”. As long as you don’t try to charge your EV battery to 100% every night, there is no major downside to daily charging. In fact, the opposite is true. Preventing the battery from completely draining to zero is beneficial as it keeps the battery at healthy levels at all times and reduces overall wear and tear.
If you drive less, you can also set the maximum to slightly less, between 65 and 80%. This allows optimal range for your daily driving without putting undue pressure on the battery. Before switching to an electric car, make sure you understand the following:
1. Your daily needs for autonomy: the lowest and the highest
Think for a moment about your daily driving needs to find a probable minimum and maximum that you would need each day. Remember to take into account weekends, day trips, and other possible future demands. Build a lower and lower number and work within that framework.
2. Your home charging setup
Will you be able to use level 2 charging solutions? Or just level 1? If so, you will be able to restore range faster without damaging the battery. If this is just level 1 then you will need to factor in slower nightly charge times. However, the main advantage of using level 1 “trickle charging” is that the lower output is smoother on battery.
3. Defining your maximum charge rate
You should be able to make sure that your charging settings will only charge the battery to the preset level, as we described above, between 65-80%, depending on your daily needs. If you don’t set it up, charging will continue up to 100%, which can add extra charge to your battery, especially if you’re using a more powerful Tier 2 or fast charging solution.
Generally, daily charging is something you can safely do if you need to, but you don’t need to charge every day if your daily mileage is low and your car’s overall range is low. In this way, you can save energy and keep running the car without draining and draining the battery when charging from scratch.
