Car Charge Times - How Long to Fill Your Battery?
With an electric car plug standard about to be finalized, and charging stations beginning to pop up in the U.S. and Europe, an important question to ask is: How long will it take to fill up a car battery? And like most technical matters, the answer is, "It depends."
Automobile batteries, whether they are nickel-metal hydride or lithium-ion, can be made up of many cells, with larger cell quantities capable of a larger storage capacity. The trade off, however, is that cars with more capacity are more expensive, heavier, produce more heat and take longer to charge. Battery life is also influenced by how "deeply" the battery charges and discharges. For example, the Toyota Prius only allows its battery to be charged to 80% of full capacity, as going beyond this point can lead to overheating (thermal runaway) and excessive gassing, resulting in a decline in battery life. All this means that the type of car you own will play a factor.
The other major factor in charge times is the type of charging system being used. The standard wall socket in most U.S. garages outputs 120 Volts at 20 Amps of current. Multiplying these units together provides the Watts, or energy per unit of time. With this amount of power, it could take a whole night (8+ hours) to get the full electrical storage into a battery. Typical European outlets produce 230 Volts at around 16 Amps, perhaps shaving a couple hours off charging times.
For car owners wanting to drive far distances without the impossible hassle of waiting 8 hours between charges, there are a couple options available. In the U.S., plug-in charging stations will provide thick power cables that make it possible to deliver the 240 Volts at 70 Amps that the plug standard is designed to handle - this would make it possible to fully charge a vehicle in an hour or two. In Europe, the plug specifications provide for 400 Volts at 63 Amps. Theoretically, this can allow a waiting time measured in mere minutes! However, with that sort of power, there is a real risk of battery damage.
Home owners also have the option of using the high powered connections in their homes that are reserved for equipment such as air conditioners. They may also buy extra equipment, like personal charging stations, at a steep price. Unfortunately, residents who live in apartment buildings will not have access to many of these options.
For individuals who only drive short distances each day, simply charging their car overnight shoud be practical and simple. Other prospective buyers will have to take into account the charging options available to them, as well as the vehicle itself. And in the not-so-distant future, advancements in battery technology can be expected to further change the equation.
Venture Capital companies and Investor Owned Utilities (IOU) invest in electric-vehicle charging infrastructure. Some stations include covered solar panel charging stations. Cities across America are implementing electric vehicle (EV) charging station in downtown areas and suburbs fostering support for electric cars.
This green energy momentum is very visible. Will this market ever complete with gas stations? Lawmakers in Washington passed a bill to allow electric power utilities and IOU's to invest in the electric-vehicle charging sector. These investments receive the usual rate of return approved by the PUC.
Regulators in many states not prohibited investor-owned utilities from selling electricity at retail charging stations. Can anyone envision pulling into a Shell or BP Station to find electric vehicle charging stations situated near the air compressors? When will the changes in the automobile industry be reflected in the gas station industry? Electric cars travel 75 to 179 miles on a charge. This problem currently prohibits cross-country travel in electric vehicles.
There are over 23,000 charging stations in the U.S. This infrastructure cost investment exceeds $130 million. These infrastructure costs decrease as technology improves and public support increases. Large areas across Texas, New Mexico, Arizona, and California are great states for this new investment.
Utilities operate large transmission and electrical grids and invest in major infrastructure projects. They are ideal investors and backers for building out charging station networks. Investors could include the automobile companies with large electric vehicle divisions.
This type of investment is permissible in the deregulated subsidiaries of Electric Investor Owned Utilities like ConEd Solutions, NRG, and DTE Energy Investments. The returns can be higher and often better or more efficient technology can be found in this area of venture capital. The return on investment in small and medium sized towns could be 8% to 12%. Many cities will want to own and control these investments. Data generated from these stations will help city managers place more as demand increases.
The green energy markets are expanding in commercial and industrial business. Imagine major corporations installing many EV recharging stations as part of their annual employee goodwill expenditures. This will happen soon.
Will pension fund money enter into this sector? Hedge funds and other energy investment investors will enter this arena as the electric vehicles market matures https://evchargingsolutions.net/. Ford, Toyota, and Tesla are selling many electric vehicles. This makes sense in a country filled with environmentalists and a nation determined to do the right thing in moving our auto industry forward.
