The Tesla Powerwall can provide up to 7 days of power to your home in case the grid goes down. Combine that with solar and you're almost completely off the grid.
Tesla has been building integrated battery systems for over 15 years. The same degree of expertise, quality control and technological innovation has informed our process of developing high-performance batteries for the grid. You can now have this technology in your home!
ELECTRIC CAR CHARGING STATIONS
There are over three million electric vehicles on the road worldwide. The more people go electric, the more demand for charging infrastructure. That’s why it’s important for you as a real estate developer to start offering charging facilities in parking lots and garages.
Because residential charging is convenient and inexpensive, most plug-in electric vehicle (also known as electric cars or EVs) drivers do more than 80% of their charging at home. Charging in a single-family home, usually in a garage, allows you to take advantage of low, stable residential electricity rates. The cost to run your car over the course of a year can be less than running an air conditioner. Charging at a multi-family residential complex, like a condo or apartment, is possible, but can be complex and more similar to public charging.
COSTS TO CHARGE AT HOME
Fuel costs for EVs are lower than for conventional vehicles. Based on the national average of 12.6 cents/kwh, fully charging an all-electric vehicle with a 100 mile range and depleted battery would only cost about the same as operating an average central air conditioner for six hours. Because plug-in hybrid electric vehicles have smaller batteries, each individual charge costs even less. General Motors estimates the annual energy use of a Chevy Volt is 2,520 kWh, which is less than required for a typical water heater. In comparison, over the past ten years, U.S. regular conventional retail gasoline prices have fluctuated from below $1.50 to over $4, squeezing annual household budgets by as much as $1,500 per average passenger car. If you charge primarily at night and your utility offers special off-peak rates, your costs may be even lower. Find out if your utility offers any special incentives for EV owners.
EQUIPMENT TO CHARGE AT HOME
Home charging can use either the relatively simple Level 1 electric vehicle supply equipment (EVSE) or the slightly more complex Level 2 EVSE. Charging with Level 2 EVSE is faster and can be more convenient, but requires special equipment that is more expensive to install than Level 1. For both types of EVSE, you should store the charging cord securely so it is not damaged, check the accessible EVSE parts periodically for wear, and keep the system clean.
You should consult EV manufacturer guidance for information about the required charging equipment and understand the specifications before purchasing equipment and electric services. In general, check with your utility and a trusted electrical contractor—and get cost estimates—before installing EVSE or modifying your electrical system.
