What Youll Pay To Charge An Electric Car

How to Recharge Your Car’s AC System (Fast and Easy)

In the United States today, electric car owners do 80% of their charging at home, adding to their electricity costs.

To estimate what your costs will be, look at your current electric bill. It should show how many kilowatt-hours you currently use and how much you pay per kWh. A kWh is equivalent to the amount of energy it takes to run a 1,000-watt appliance for 60 minutes.;

The national average price of electricity is 13 cents per kWh, and most electric vehicles can travel four miles per kWh.

So if you typically drive your car 1,000 miles a month, then youll need at least 250 kWh to charge it properly. At 13 cents per kWh, that will cost you $32.50 a month.;

If you live in a state with higher electricity costs, such as California, then your electric bill will, of course, be higher. In California, as of this writing, the average cost of a kWh is 21.93 cents. So if you drove 1,000 miles per month, then you would pay $54.83.;

Check The Refrigerant Pressure In The Ac System Of Your Car

Next, you need to check the refrigerant pressure in your cars AC to be sure that the loss of cooling is caused by a decrease in gas pressure. Here is how to do it:;

  • Locate a grey or black plastic cap attached to an aluminum pipe in the engine bay.;
  • If you cannot find it, trace the large coolant line coming out of the passenger compartment and into the engine bay and youll find the cap on it.
  • Remove the cap and attach the pressure gauge to the service port beneath it to check the pressure.
  • With the AC turned on and on the lowest temperature settings, make sure that the AC compressor clutch is engaged.
  • The pressure of the refrigerant in the system needs to be at least 35psi. Anything below that indicates that your AC needs recharging.

How Often Does Car Ac Need To Be Recharged

How Often Does My Car AC Need to Be Recharged? Theres no hard and fast rule here. Some new cars that stay cool with R134a may only need to be recharged every seven years or so. Living in a hot place like Gilbert though, theres a good chance youll feel the need for a recharge even more often than that.

The Costs Of A Solar System: $7000 And Up

Unless youll be charging electric cars for many years to come, it can be difficult to make an economic case for installing a solar system just to serve your EV.

In the Los Angeles area, a 1-kilowatt solar system produces an average of 4 kWh of power per day. A Chevrolet Bolt, which is EPA-rated at 29 kWh/100 miles and is one of the more efficient EVs available, would need at least a 3.6-kW system to get 50 miles of range per daily charge. Such a system costs about $7,000 and doesnt include the cost of a storage battery to hold power for overnight charging. That feature could double the cost. Put another way, a $7,000 system would purchase over 134,000 miles worth of power for a Bolt, assuming a rate of 18 cents per kWh.

Solar starts to make more sense if you install a system capable of providing electricity for the household as well as the EV. Upfront costs of owning a solar system outright can be steep. But on average, a properly sized whole-house solar system will pay for itself over about seven years and will last for at least 25 years. Costs are largely dependent on the size of the system, regional labor rates, the quality of the solar panels and power inverter used, and the complexity of the installation.

The national average installed cost of a 6-kW system is $12,920, or $2.15 per watt, after applying the 30% federal tax credit, according toEnergySage, a Boston-based service that links homeowners with solar system providers across the country.

It’s All About The Pressure

Checking Pressures & Charging Automotive Air Conditioning ...

Air conditioning systems leverage high-and-low pressure. Before the Freon is converted into a liquid in the high side, it starts out as a gas in the low pressure side of the system. The vehicle is kept cool by the constant circulation of refrigerant through the high and low pressure sides of the system.

Car Air Conditioner Recharge

Refrigerant has two jobs: cool the air, and sustain enough pressure to blow air through the AC system. Lose a little — and your AC wont cool the air like it used to. Lose a lot — and your whole AC system can stop kicking in due to low pressure.

A Car AC Recharge fixes the most common problem diagnosed in Car AC Repair service: low refrigerant.

What Would Causes High Pressure On The Low Side Of A Ac System

What is An Expansion Valve in My Cars AC? The expansion valve failing is another thing that can cause the pressure on the low side to go too high and the high side to go too low. Your expansion valve is located at the evaporator and regulates the flow of refrigerant through the AC system as a whole.

Heres How To Recharge Car Ac

Anybody who can follow instructions can recharge car AC. Get your glasses and gloves, grab the refrigerant and attachment hose, and lets get chilly!;

  • Turn the car on, make sure its in park, and put the parking brake on.
  • Turn the AC to its coldest setting, crank the fan to its highest setting, and hit the button to recirculate the air.
  • Pop the hood, find the AC low-pressure service port between the compressor and the evaporator, and remove the plastic cap. If you are unable to find the service port, A/C Pro offers a handy online port finder. A secondary method is to use the connector piece from the refrigerant hose, as it will only fit on the low-pressure port.
  • With the attachment hose disconnected from the can of refrigerant, connect the hose to the low-pressure point.
  • With the compressor cycling, look at the included gauge and rotate the temperature dial to the current temperature.
  • If the pressure reading is in the red portion of the gauge, do not recharge. This is a sign of a bigger problem, possibly a faulty or malfunctioning compressor.
  • If the PSI reads lower than the designated full area on the gauge, it needs more refrigerant.;
  • Detach the hose from the service port.;
  • Remove the safety tab from the can of refrigerant, shake the can, and reattach the gauge and hose to the can.
  • Connect the hose to the low-pressure service port and use the trigger to begin recharging the system with refrigerant. Rotate the can up and down to maintain good refrigerant flow.

    Car Air Conditioner Freon Charge

    In September 2017, Mayor de Blasio announced a $10 million investment in EV fast charging stations. NYC DOT, in conjunction with MOS, is building a network of fast chargers across the city. These hubs will feature up to four DC fast chargers and two Level 2 chargers. Hubs will be in city-owned public parking lots and garages.

    The first two DC fast charging hubs are the Court Square Municipal Garage in Queens and the Delancey/Essex Municipal Garage in Manhattan. The City will continue to install DC fast chargers to support the growing number of EVs. More DC fast charging is planned for municipal lots in 2022.

    How it works:

    • An EV driver parks in a DC fast charger space
    • Driver begin a charging session via the EV Connect App or by swiping or tapping their credit or debit card on the charger
    • The driver plugs in their vehicle
    • The app will notify the driver when the vehicles battery is 80 percent charged

    Notes: Each charger has CHAdeMO and CCS connectors, which are compatible with most EVs. Tesla owners will be able to use the fast chargers with Teslas CHAdeMO adapter.

    The fee to charge is 35 cents per kWh consumed. Drivers must pay for parking at the municipal lots. DC fast charger customers will have the cost of the first hour of parking deducted from their charging session.

    What Is An A/c Recharge

    During a car A/C recharge, your A/C system’s old refrigerant is evacuated and replaced with new refrigerant to help ensure your air conditioning system is operating properly and keeping you comfortable.;

    At Firestone Complete Auto Care, our A/C recharge service starts with the Firestone A/C Performance Check, wherein one of our experienced tire and auto service professionals:

    • Visually inspects all A/C components
    • Runs a performance test
    • Performs a system state of charge test
    • Performs a system control test
    • Performs a leak test using an approved electronic leak detector

    Diy A/c Charging May Not Work On Very New Or Very Old Cars

    Most DIY canisters are filled with the R-134a type of refrigerant. This is the type found in most cars on the road today — but classic cars built before 1994 were designed for R-12 refrigerant. What’s more, many of today’s newest cars use the latest refrigerant called R-1234yf. You cannot mix refrigerant types, and putting the wrong refrigerant in your car will cause damage to the air conditioning system! If you’re not sure which kind of refrigerant your vehicle takes, DIY A/C charging may not be for you.

    Determine Ambient Air Temperature

    If the temperature of the air is 55°F or below, do not charge the vehicle. It is also always recommended to use acharging hose with a gauge. The refrigerant packaging should contain a chart like the one below for determining what pressure to charge the system depending on the ambient air temperature. If no chart is provided, use the A/C pressure chart below this list as a general guide. Also, different AC systems can have different recommended pressures, so its worth taking a look in a repair manual or online to determine the right pressure for your vehicle. Following these guidelines when recharging the system will ensure the system can operate efficiently. It is important to note, charging an AC system with just a single gauge attached to the refrigerant is possible, but it is always recommended to use a complete set of manifold gauges, which monitor both the high and low side pressures. These gauges are available for sale, and for rent at most AutoZone stores. At this point, start the vehicle and set the air conditioning to MAX setting. Locate the vehicles AC compressor for reference, and its important to monitor what the AC clutch is doing. When the AC compressor is disengaged, only the outside of the pulley will turn. When its engaged, the entire clutch assembly will turn, driving the compressor. Your compressor is designed to not engage at all when refrigerant pressures, or volume is too low.

    How To Properly Recharge Your Cars AC System

    Because of the sensitivity of this procedure, we will explain how to use the AC recharge kits. They have shown to be the most effective and safest option in comparison to trying to repeat a mechanics role at home.

    Materials Needed:

    • Meat thermometer
    • Refrigerant .
    • Safety glasses and gloves

    • Tip: Always wear safety glasses when performing work under the hood. It is especially important to be careful to not get any refrigerant on your skin as it freezes quickly and is very painful. Please be sure to follow all instructions that are included with your AC recharge kit and read every canisters warnings carefully.

    Step 1: Turn on your AC. Start your car and turn your AC to Max or High.

    Step 2: Determine if AC compressor is engaging. An AC compressor is a device driven by the accessory belt that converts the refrigerant from liquid to gas. The compressor has a clutch at the end of it that should be spinning with the accessory belt when the AC is on high. Look for these pulleys moving.

    Step 3: Test the pressure. To test the pressure, turn the vehicle off and locate the low side pressure port. The low side pressure service port is generally located on the passenger side of the engine bay. It will have a black or grey cap on it with the letter L.

    • Tip: If you are having a hard time finding it, try locating the two aluminum pipes that are coming out of the firewall and trace the larger-diameter pipe until you find the service port.
    • Proceed until you are as close to 40 psi as possible.
