tesla home charger speed

The additional cost is well worth it for the extra gripping strength provided by industrial-grade outlets. You would, therefore, plug one end of the 20A NEMA 5-20 adapter into the outlet, and the other end into the Mobile Connector (which then plugs into the car). But, regardless of the work that is done, the amount of current flowing in the hot wire should always be the same as the amount current flowing in the neutral wire. All Rights Reserved. Some codes may require plastic when mounted behind the drywall between a garage and a living area. And 50 mA is likely fatal. Some RV parks have special 120V 30A outlets that accommodate travel trailers and smaller RVs. Existing electrical infrastructure and costs to upgrade to a higher amperage circuit if needed. Understanding How Magnetism and Thermal Expansion. The fact that the 3rd party adapter uses the Tesla 14-50 adapter means that the car thinks it is plugged into a 240V 50A outlet when it, in fact, it is a 120V 30A outlet! Given that you are asking for the best performance from your outlet it is wise to swap in an “industrial-grade” outlet. There is an easy calculation that determines the outlet required, or if you would benefit from a dedicated charging device such as a Tesla Wall Connector, which is capable of higher charge rates. An EVSE is simply the connection between the car and the power source, such as the Mobile Connector, but a hard-wired EVSE is usually connected directly to an electrical panel and can provide more current than any outlet is capable of. In the two-wire 240V circuit, 240V is the only voltage you can get. It can be used on any circuit from 15 to 100 amps, but only charges based on the limits of your car. What’s the difference? Go to an electrical supply house. If you live in a wooded area you could strip all the branches off the trees and have a circular platform loaded with rocks that are raised to the treetops during the day via solar-powered motors. EVSE Adapters – 3rd party adapters for electrical outlets that Tesla does not have an adapter for. For the 50A 14-50 outlets, Tesla recommends the Hubbell HBL9450A, or the Cooper 5754N. Tesla Wall Connector supplies a full charge without ever leaving the house. Quite a bit of the NEC is focused on reducing the risk of fire, for which the insurance industry often ends up paying. The wires then feed from the meter into your service panel. Should you upgrade to a higher-power outlet or Wall Connector for the future? TeslaTap is not affiliated with Tesla, Inc. or its subsidiaries. It’s a bad idea. Solar power is a use-it-or-lose-it thing unless you have a way to store all that photonic energy. Determining the Best Charging … A: The same answer as above except you need a 240V 20A outlet. Let’s say you are charging from a 20A outlet. Install on the 60A circuit to charge one car with the long-range battery at the maximum rate. Between the breaker and the outlet or Wall Connector is a run of wire. Since a personal home Supercharger costs more than the car, you can take advantage of the fact that charging at home can be done at a more leisurely speed… often overnight while you sleep. Where that current may leak to is something we’ll take up in a moment. This is more than sufficient for overnight charging. Your car has a built-in charger that maxes out at 32 amps for the standard-range battery and 48 amps for the long-range battery. Destination Chargers are just Tesla Wall Connectors. Page 1 of 3 1 2 3 Next > Robert A Member. The current in this circuit is tricky. The magnetic field appears and disappears and shrinks and grows virtually instantaneously with the rise and fall of the current, so this trip mechanism in the breaker reacts instantly to sudden large currents. The ChargePoint good things. Ask specifically for an industrial-grade outlet or order it yourself in advance. EV rates and schedules vary among utilities, but let’s take the same example above and assume your utility allows for EV charging at discount rates between Midnight and 6 AM. But, if we select the right substances, one strip grows longer substantially faster than the other and this causes the bonded combination of the two to bend, to curve as one side gets longer faster than the other. Some do this more than others, Copper, what we often use for electrical wire, doesn’t do it as fast as say nickel-chrome which is what we make electrical heating elements out of. After consulting the chart below consider how far your electrical service is from where you park your car. That is a NEMA 6-20. For example, many power utilities offer a lower rate if you charge between midnight and 6 am, so this may be your preferred charging time. Most substances don’t change as much as water does and most actually shrink as they cool, but you get the point. Both chargers are Level 2 240 volt high speed charging stations that can charge your Tesla at the fastest rate it can currently accept from a home charger, assuming you have it wired at maximum capacity (which is based on installation and your breaker box). It … These adapters are recommended because they properly signal the car to charge at the appropriate rate. Also, be sure that your outlet is installed in a place that stays dry and that it is at least 18” above the floor to prevent the Mobile Connector module from dragging on the floor. A: The first thing you need to know is that all electricians are not created equal! An array of thin copper plates that are not electrically connected to each other serve to dissipate the arc away from the contacts. If it detects any missing current — well, more than 20 mA of missing current — then it shuts everything off virtually instantly. Don’t accept aluminum wire. It is important that the car never draws more current than the electrical circuit is rated for. There are plenty of Tesla-related blogs and forums discussing Level 1 charging. The Tesla adapter signals the proper rate of charge for the outlet type it is connected to. The adapter signals the onboard charger to draw no more than 16A. There are many breaker types, but the breaker must match the service panel design. It is a limitation of the size of the charging cable. That is why the long-range battery is limited to being charged at 32-amps, or 30 miles of range per hour, even on a 50A circuit. Avoid a big box store like Home Depot or Lowes. Throughout this article, we assume the car is not charging in freezing weather. If your solar is NOT tied to the grid, you have few options. Hardware Description; Wall Connector. Your electrician can determine the proper types for your specific installation. The outlet must be in good working order (no loose connectors, broken housing, or burn marks). The breaker shown is the recommended minimum size for the fastest charging of your car. Well, unfortunately, there is no such thing as safety, only degrees of danger. For the extra $200 you get the advantages of the Wall Connector noted above. Done properly, it may also increase the value of your home to a future buyer. Ideally, the wires should be one continuous run from the breaker to the outlet or Wall Connector. This change boosts charging speed to 11 mrph. A: It can be. What about the ground wire which is often just bare copper or may be insulated with green plastic or green with a yellow stripe? At night the platforms would be released, and they would create power via regen on the same electric motors to charge your car. I need faster charging on the road due to very long days on the highway, and my route doesn’t take me near a Supercharger. That’s a really bad idea for your regular daily charging scenario. No batteries though. The Tesla Wall Connector is rated only for copper wire. If all the energy from them was … Before purchasing a second Mobile Connector for $300, take another look at the Tesla Wall Connector for $500. Tesla makes a special Corded Mobile Connector that plugs into a 14-50 outlet. One version of the Dryer Buddy requires you to use your 50A 14-50 adapter to plug into a 30A outlet! Here is the maximum charging current for each Tesla vehicle: Power lines to your home arrive underground or overhead from a large transformer. In a 240V two-wire circuit (again, we’ll get to the three-wire circuit in a moment, trust me) there are also two wires. In extreme cold, charging at 120V may only keep the battery heated and may not add any additional miles of range! Better flexibility: Install on a 40A circuit to charge one car with the standard-range battery at the maximum rate. Don’t go with the lowest bid. Charging your Model 3/Y at home is different from charging on the road. Let’s say you have a NEMA 14-50 outlet. Here’s an example: Cathy wants to go camping in her Tesla. Tesla does not make an adapter for this outlet, but EVSE Adapters has a TT-30 adapter. Be forewarned however that the current draw from your car may be higher than any load serviced by the outlet before. It’s attached to any exposed metal on the appliance so that if something inside breaks and the hot wire or L1 or L2 touches the metal which may be touched by the user, that current immediately flows through the ground wire tripping the breaker and making the situation safe. The Wall Connector has a dial that lets you configure it for the circuit amperage you are plugging in to. This is why GFCIs are required on outlets used in bathrooms, laundry rooms, kitchens, garages, outdoors, around swimming pools and spas, places that can be expected to be wet. Once you or your electrician selects the outlet size, we strongly recommend using an industrial outlet. Neutral is always color-coded white. Stipulate the use of COPPER wire. Lower rated circuits result in lower charge rates. On-road trips your time is limited, and you want the fastest charge possible. A big thanks go to our guest columnist Chuck for the GFCI section! Third-party hard-wired EVSE devices are available, but few compete with the Tesla Wall Connector on price, nor are most capable of charging the LR battery at maximum speed (a 60-amp capable EVSE is required). If you do feel you need to keep the MC within the car, then you should consider getting one of these options: The Wall Connector can be set with an internal switch to work with 15 to 100-amp service. For example, if you are installing an EVSE such as a Tesla Wall Connector you may wish to have a NEMA 14-50 outlet installed at the same time. So, again, it’s good to shut things down. Sometimes one is white but painted black or red, or wrapped with some black or red tape; this is called “decoding.” In this case, current flows between the two legs so that the current in L1 must equal the current in L2. In addition, a city can elect to skip sections or have additional local requirements. Most EVSEs cannot charge at more than 32 amps, so make sure to check carefully before buying something other than the Tesla Wall Connector. Again, there might be some “leakage” in “the real world” and code allows up to 20 mA. Many cities and counties adopt the code as a requirement for work done within the region. First, it depends if the EV is being charged at home or on the road. Grid-tied means you are connecting the solar inverter (the thing that turns DC from the solar panels into AC to run the house) to the electric utility, and you have the potential to sell power to the utility. The Tesla Wall Connector has a maximum power of 40 amps, which means it can charge a car 25% faster — about 25 miles of range for every hour of charging. Charging a Tesla Model S at home. If your utility company offers discounted rates for EV charging you may wish to charge only during the lowest cost rate period. Charging speed is limited by the car’s on-board charger (11.5 kW) Battery intake [2] kW . A: Either option has its own merits. At home, you have the flexibility to charge your car at Destination Charger speeds as well, or you can typically charge as slow as 5 miles of range per hour from a standard 120-volt electrical outlet… or somewhere in between utilizing various types of outlets. Q: I have heard of a product on eBay called Dryer BuddyTM that lets you share a dryer outlet with your EV. For example, let’s say you used our range calculator and found that a NEMA 6-20 (240 VAC, 20 amps) would be adequate for your daily charging needs. The one you might want would be the one that plugs into a 14-30 (if that’s the outlet in your wall) and just duplicates it to two 14-30 outlets. Now that you have determined the number of miles of range per hour you wish to put back into your car each day, you need to determine the electrical service required to plug the car into. In Australia these are installed locally at a Service Centre either at the time of delivery of your car, or added later on. You’ll also need to switch wires to a new 240V dual breaker. An electrician can evaluate if there is adequate power for the home and the necessary open breaker slots for your planned EV charging. NEMA 6-50 requires 2 wires plus the ground wire. If your panel has no open slots, you may be able to replace two breakers in two slots with a quad breaker in those same slots. Metal is also preferred for an EV outlet, as it is far stronger. For the fastest home charging, install Wall Connector with a circuit breaker that matches your vehicle’s onboard charger capabilities. This is a common outlet used by many EVs. Can do? Like the 6-50, two of the wires create a 240V circuit. Current flows from the Hot to the Neutral. At one time in your youth, probably in some science class, you wrapped some wire around a nail and then connected it to a battery and, lo and behold, you could pick up paperclips with it. You also know from practical experience that as you heat things up or cool them down, their dimensions, length, width, thickness, change. So if you get the proper one with two 14-30 outlets in the PLUS AUTO version, it’s about $295. Cars with the dual-onboard charger option could charge at 19.2 kW (80-amps), so Tesla needed to offer a home charging solution that could deliver that much power, but … The outlet type is called a TT-30. There is one consideration that may affect the number of hours available to charge the car. Q: Where can I obtain adapters and other charging accessories that Tesla does not make? If you’re installing an outlet consider claiming it is for an RV, not an EV. NEC code requires the cord to be under 1 foot in length. The industrial-grade outlets have spring tensioning in the receptacle to ensure a tight grip and better withstands repeated insertions of the charging cord. Here is an example of an industrial-grade Leviton 5461 outlet. Tesla Gen 3 Wall Connector provides a full charge overnight for every homeowner. This should work for both Tesla vehicles and non-Tesla EVs. Normally, no water flows down the overflow drain. Basically, current in L1 minus current in L2 plus current in neutral must equal zero. The Mobile Connector is included as standard equipment with a new Tesla. Member “Rocky_H” responds to a member leaning toward buying the version that comes with a 50A 14-50 socket. Some say 40 or 48 amps. When the breaker handles a short circuit, hundreds of amps may be flowing for a very short duration. These outlets can be costly, but we feel they are well worth it. If you forget to turn down the amps in the car or if it resets from a software update or something (that happens sometimes), then you are overdrawing the circuit, and you need to hope the breaker trips. When more than 20 mA is unaccounted for, it’s better-safe-than-sorry, best to shut everything off. Aside from the hassle, high-power outlets are poorly suited to many insertions and removals.
