Gas to Electric (ICE to BEV)
The End Of The Ice Age
Internal Combustion Engine (ICE) -vs- Battery Electric Vehicle (BEV)
There are four basic types of technology currently in the market place for cars:
- ICE: Internal Combustion Engine: Traditional standard gasoline combustion engine. The battery is mainly used to crank the engine.
- HEV: A Hybrid vehicle that has both a gasoline combustion engine and an electric engine (NON plug-in). The batter is mainly used to boost the engines overall power and energy efficiency.
- PHEV: Plug-In Hybrid Electric that has an electric engine ‘and’ a gasoline engine. The battery is mainly used while driving shorter distances (first 25-40 miles), and after that the battery is used to boost the engines overall power and energy efficiency.
- BEV: A state-of-the-art ALL electric engine with batteries known as a Battery Electric Vehicle or a Plug-In Electric Vehicle (PEV). No gasoline engine. The battery fully supports the vehicle.
As we move toward electric vehicles like Tesla, Volkswagen, GM, Ford, and with others on the way from Honda, Nissan, Mercedes and Fiat … below is a short review the pros and cons of electric cars as they now exist. Below are the things to consider prior to choosing one vehicle over another. If you want a chart of the cars and their manufacturers, please email us and we will send you my side-by-side comparison.
- Green Is Good Economic Power: Leaving aside the environmental benefits, which are considerable, all-electric cars and their hybrids mean freedom from oil addiction and saying goodbye to its related constraints is a big motivator.
- Cheap Fuel: Average cost of $13 for BEV versus $56, for an average 300 miles, is important to note. That gap will become even wider if gas prices rise in the coming years.
- Less Maintenance: Because they don’t have to deal with the heat and force generated by an unending series of powerful explosions the way combustion engines do, electric engines don’t need the oil changes and other regular maintenance that conventional engines need to stay running. That can add up to significant savings over time.
- Tax Credits: Significant state and federal tax credits, along with grants and rebates, will be around for many years to come.
- Range: Current battery technology is matching the energy stored in a regular tank of gasoline. Electric passenger vehicles can now go upwards of 350 miles on a single charge. That means in the near future, ALL electric cars will have even more range than comparable combustion cars, as they exceed electric storage capacities greater than 600 miles per charge.
- Prices: An average BEV cost of $30-40,000; as compared in contrast, to a standard ICE car will cost around $25-35,000.
- Options: Owners keep their cars. There likely won’t be as large a used inventory of electric cars for years.
- Infrastructure: Public charging stations are not as frequent as gasoline stations currently … however, many many more charging stations outside of the standard gasoline station are coming online each day at the work place and many public destinations.
- Charge-time: Average wait times can be upwards of 30-60 minutes or more to “fill up your tank”. At home you’ll want a Level 2 ‘faster’ charger installed, potentially adding $650 more to your electric-car price tag.
If you are thinking about going all electric, there are a few things to consider before you drive it home:
- Are you buying a plug-in hybrid or a battery electric car?
- Is your home’s electrical panel and wiring configured to enable you to charge the battery in your car?
- What is the best rate plan for you to charge your vehicle on?
- What is the best time for you to charge your vehicle?
- Do you need to hire an electrical contractor?
- Will you need to obtain city permits for any electrical work?
Charging A BEV:
Understanding Charging Options: One of the most important decisions a plug-in electric vehicle owner will make is how to charge their vehicle. Most plug-in electric vehicles will charge at home on one of two charging “levels.” Depending on which charging level you select, you may need to upgrade your home electrical system.
Level One. Charging at Level One is done on a standard 120-volt outlet that typically won’t require customers to make modifications to their electric panel or home wiring. The electrical draw is the rough equivalent of a 1500-watt personal hair dryer. Most plug-in hybrids will take four to six hours to fully charge at Level One. A battery electric vehicle will take 12 to 24 hours for a full charge. The ideal configuration for Level One is a dedicated circuit that can be use for the electric vehicle charge connection.
Level Two. Charging at Level Two is done on a 240-volt rated charging unit and will likely require customers to make changes to their electrical panel and add a new circuit (if one is not available) in their home similar to that used for an air conditioner or electric dryer.
Most battery electric vehicles would take three to six hours to fully charge at Level Two. Faster rates of charging can be achieved but may require power consumption greater than the peak load of a whole house.
The Society of Automotive Engineers has set the standard for Level One and Two charging plugs, known as the J1772. The five pin smart plug conducts electricity and sends data about the flow of electricity.
Level 2 PLUS and Level 3 Fast Charging. AC & DC Fast charging varies in electrical needs
Permits For Electrical Work: Local government permits may be required prior to installation or construction. The local building and safety department should be consulted to determine specific requirements. If an electrical contractor is hired to perform the work, it is still the homeowner’s responsibility to ensure that the appropriate permits have been obtained.
If permits are required, a city or county building inspection must be completed prior to activation of the new charging circuit for the plug-in vehicle. It is the homeowner’s responsibility to verify that all required inspections are completed satisfactorily.
Plug-in vehicle charging equipment installation costs can vary greatly depending on the configuration of the home and electrical circuitry, local code requirements and the type of equipment installed. A licensed electrical contractor can provide a cost estimate.
Basic Charging Circuit Requirements: In accordance with the California Electrical Code (CEC), all residential plug-in vehicle charging circuits are required to meet certain guidelines.
- Level One – Either a 15- or 20-amp single-pole breaker is required.
- Level Two – A 40-amp, two-pole breaker is necessary.
Electric Vehicle Supply Equipment (EVSE)
- Level One – A 15- or 20-amp standard residential wall plug and receptacle is acceptable for 120-volt charging.
- Level Two – According to the National Electrical Code® (NEC) and the CEC, in 240-volt electric vehicle charging equipment installations, the supply equipment should be wired permanently to the electrical supply circuit. The supply equipment may vary in design depending on the manufacturer and vehicle type, but it must meet specifications set forth in the NEC. These specifications include:
- Equipment that is listed and labeled;
- Ground fault protection;
- Diagnostic capability to prohibit charging from taking place when the batteries or the vehicle is damaged or an unsafe condition exists; and
- An interlock that de-energizes the charging cable when the vehicle is disconnected from the charging equipment, or if excessive strain is placed on the cable/cord.
Customers should check with the auto manufacturer to determine what type of plug-in vehicle charging equipment is required and should consult local code officials to determine specific installation requirements.
In limited circumstances, an exhaust fan may be required by state or local codes to ensure proper battery ventilation. Generally, all new plug-in electric vehicles expected to be produced by major automakers will use sealed battery packs that greatly reduce the possibility of gaseous release during charging. These vehicles may be considered exempt from ventilation requirements. Again, customers should check with the vehicle manufacturer and with the local building inspector’s office for requirements.
Local government permits may be required prior to installation or construction. The local building and safety department should be consulted to determine specific requirements. If an electrical contractor is hired to perform the work, it is still the homeowner’s responsibility to ensure that the appropriate permits have been obtained.
Rate Plan Options
Buying an EV means that your household’s electricity consumption will soon change. There are rate plan options available for electric vehicle owners; check with your utility to see which one’s apply.
- Residential Plan (Schedule D). Under the standard residential rate plan, the price per kilowatt-hour is tiered and increases as the amount of energy usage over your baseline allocation increases. Unless you have specifically selected a different rate option, you are probably on your utility’s standard residential rate. Remaining on this rate is the simplest choice, but it may not be the cost-effective choice for some plug-in electric vehicle owners depending on how you use electricity.
- Home & Electric Vehicle Plan (TOU-D-TEV). This rate option uses a tiered structure similar to the standard residential rate, but provides lower electricity rates at night, when many plug-in electric vehicle owners are likely to charge their vehicles. This rate may be ideal for customers who have low usage during peak daytime hours of 10 a.m. to 6 p.m.
- Electric Vehicle Plan (TOU-EV-1). This rate uses a second meter to measure the electricity you use to charge your vehicle, so that it can be billed at a separate rate from the rest of your home. Rates are discounted for charging that occurs during ‘off peak’ nighttime hours. This option potentially gives customers the lowest rates for electric vehicle charging, but also involves more initial set-up cost and time.
