AC ev charger

The differences between AC charging pile and DC charging pile are mainly as follows:
1. Charging time.The most essential difference between slow charge and fast charge is the charging time. Generally, it takes 1.5~3 hours to charge the power battery with DC charging pile.The charging with AC charging pile usually takes 8~10 hours to fully charge.
2. Vehicle charging machine.If AC charging pile is used to charge the power battery, it needs to be charged by the on-board charger on the car, while DC charging pile can be directly charged, which is also the biggest difference with DC charging.
Dc charging pile is commonly known as “fast charge”, which is fixed outside the electric vehicle and connected to the AC grid. It is a three-phase four-wire 380V stable frequency of 50HZ and can provide DC power for non-on-board electric vehicle power batteries.The AC charging pile, also known as “slow charge”, but the AC charging pile has no charging function, and must be connected to the vehicle charger to charge the electric vehicle, which only plays a role of power control.

1.The magnitude and direction of alternating current change periodically with time.Direct current does not change direction.
2. Ac has no positive and negative poles, DC positive and negative poles can not be interchangeable.
3 storage characteristics: DC can be stored, such as a variety of batteries, strong mobility.Alternating current cannot be stored and can only be generated as needed.

Modern electric cars have gone further than their predecessors, but the question remains: How far can you go on a single charge?Electric vehicle (EV) range varies according to several factors we will explore here.
How many miles can an electric car go on a full charge?
According to the Plug-in Hybrid and Electric Vehicle (PHEV) Research Center at the University of California, Davis, the average figure for how far you can go on a single charge is 250 miles (as of this writing in June 2022).Some models will get less mileage, and some models can get 350 miles or more.But what accounts for the difference in scope?Why don’t all electric cars get the same mileage on a charge?
The answer depends on factors such as the size of the EV’s battery and how old the vehicle is.Driving behavior and weather also play a significant role in how far an EV can go on a charge.
Data collected by the EV database shows that there is a wide gap between the minimum and maximum average range of an EV on a single charge.At the lowest end of the spectrum is the Smart EQ Forfour, which has an average practical range of 55 miles but can reach 90 miles in ideal conditions.At the high end, the Lucid Air Dream Edition R has an estimated average range of 430 miles.
At the time of writing, the average range of most mid-range vehicles is between 200-300 miles.The U.S. Department of Transportation (DOT) estimates that people drive an average of 13,476 miles per year or about 36 miles per day, and even mid-range EVs are enough to meet typical daily driving needs.
It’s worth noting that, at the time of writing, almost all of the most numerous EVs on the market are expensive and probably not what most drivers deal with in terms of range.Most people buying into the electric vehicle market today will get a figure closer to the average of 250 miles at the UC Davis research center.As battery technology advances, we are likely to see an increase in average range over the next few years
Another important caveat is that these range estimates apply to all-electric, battery-powered vehicles.Hybrid cars that switch fuel between the tank and the battery will get higher average mileage.
What will affect the range of an electric car?
Multiple variables, from weather to battery size, affect the range of an electric car.
Cold weather, for example, drains the batteries of electric cars more quickly because the liquid components thicken and the reactions that generate electricity slow down.Built-in battery heating and cooling systems help alleviate this problem, but it’s something potential EV buyers should know about.Electricity is also needed to run a car’s heating system, because electric motors do not generate their own heat as gasoline engines do.
The size of an electric car’s battery pack is crucial to its range.The larger the pack, the more lithium-ion batteries are used to store electricity to power the engine.The more energy you store, the longer the car will go.Ev battery pack capacity is measured in kilowatt-hours, and the larger the number, the greater the capacity.The Lucid Air Dream listed above has a battery capacity of 118kWh, while the Smart EQ Forfour has a battery pack capacity of 16.7kwh.The Lucid Air’s larger battery pack gives it more capacity and therefore longer range.
Driving habits also affect range.A lot of highway driving or rapid acceleration will drain the battery faster, because those things require extra power.Stop-and-go traffic, by contrast, gives regenerative braking a chance to regain some of the lost energy.

Level 3 charging, also known as DC quick charging, is the fastest way to charge your vehicle.The Hyundai IONIQ 5 is used as an example to show how fast a battery can be charged using L3.The L3 charger can charge the IONIQ 5 battery from 10% to 80% in about 18 minutes.It’s great, perfect for long trips that require hitting the road as soon as possible.

Ultra-fast charging like this can only be done using public chargers, so you won’t be able to install one of these in your home.And, to be honest, installing one of these chargers in your home is pointless.You’d better use the public one and go home.

You should definitely avoid completely draining your EV’s battery.Doing so can negatively affect the battery’s capacity and shorten its life.The optimal charging range for electric vehicle batteries is usually between 20 and 80%, so try to stay within that range.
Thankfully, many modern electric cars come with alarms that tell you when your battery is low.Some higher-end products will even alert you when you’re near a charging station so you can recharge immediately.You can usually see how many miles you have left to go before the battery dies, so you can recharge well before you get stuck.
Unlike gasoline cars, where you can sometimes go a few miles further from the tank when the gas light is on, electric cars finish when it reaches zero.When this happens, you will be towed to a charging station, so please avoid letting your battery die.A full day or a night at home can go a long way toward eliminating this problem.
How do you know what range to look for in an electric car?
To know what range you need, count the number of times you drive each day and go from there.Can the average range of the electric vehicle you want meet this demand?If so, this is a good candidate.
Consider what charging infrastructure is near you.Can you use public charging stations?Can you top up at work?Charging at home at night?Longer range doesn’t make much sense if it’s too hard to charge where you live.
What’s the climate like where you live?If it is very hot or very cold, you need to take this into account as it will at least reduce your range.
Finally, know that an electric car’s battery degrades over time, which means it loses some of its original range.Most likely it won’t be a huge number – it’s usually 5% in the first few years – but it will happen.Take the original estimate range, calculate 10 percent, and subtract that number from the original range to see if it still meets your needs.
These factors together should give you a good idea of whether range will be an issue for you when driving an electric vehicle.People often find they can get around just fine in an electric vehicle, but it’s best to do your homework to avoid unpleasant (and expensive) surprises.
