There is a need to adapt the products for home use of electric and hybrid car batteries not only for power backup during blackouts but to smooth out and ease the demand for electricity at peak hours of usage. By expanding the electrical installation of "smart meters" power companies can charge a variable rate that will make the price you pay for power at peak times today are very expensive.
Having high-capacity batteries such as batteries used in electric cars in your home will not only be able to supply power for hours during a power outage but will also help pay for itself by reducing your costs during peak demand time. You can check this out to get the best rechargeable battery backup at a reasonable cost.
Two-stage forced-air furnaces modern requires only enough power to run the fan and control. natural gas pressure will be maintained and the battery will supply power to control the water heater. If the homeowner continues down the heat and limit the use of hot water, the battery will supply power for maybe a few days.
If propane (which can be stored for years in a steel tank) or natural gas (petrol has a short shelf life) Generator was added, the battery can be recharged indefinitely as long as natural gas or propane is available. (A device that can harness the power generating capacity of hybrid cars for domestic battery charge can be developed).
The battery will help pay for itself as a standby power source during peak draw like 17: 00-19: 00. The battery will be connected to the "smart meters" and when electricity prices are rising, the device load shedding will stop drawing power from the grid and switching to battery.
