Who killed the electric car?

Electric carsW can be better for the environment than regular cars. However, the electricity they use must come from a renewable source, else they can be even worse than regular cars. Another thing to consider is their lifespan and the carbon footprint of their production. If their lifespan is too short, or their production too inefficient, then the CO2 they save during their lifespan may not suffice to make up for the extra CO2 spent in producing them.

Electric cars can also be cheaper to run because electricity is generally more affordable than diesel or petrol, though the upfront cost (the cost of buying an electric car) is generally higher. If the electricity comes from your own photovoltaic system, then recharging can be essentially free. In most cases, one charge will last around a hundred miles. All which is more than enough to get you to work and back more often than not. Especially as around 80% of drivers will drive less than 40 miles in a day.

Regarding pollution while driving, electric vehicles create only 1% of the pollution generated from even the cleanest gasoline vehicles.[1]

As the popularity of electric vehicles continues to grow, it has become increasingly important to develop and maintain an adequate charging infrastructure. Electric cars rely on battery power rather than traditional fossil fuels and must regularly recharge to remain operational. Unfortunately, more robust charging infrastructure is still lacking in many areas, mainly rural, making long trips difficult for EV owners.

To address this problem, we need to invest more resources into developing new charging stations that are reliable and cost-effective. This requires creating optimal locations for these stations as well as setting up a system of payment and support services to ensure their continued use.

Overall, this issue deserves greater attention from policymakers and businesses alike. Providing adequate EV charging infrastructure can help improve access to clean transportation for millions of people.[2]

Advantages[edit | edit source]

Compared to internal combustion engine-powered cars:

  • They have less carbon dioxide emissions, which contributes to the depletion of the ozone layer. Even though some electric cars may use power that comes from shale -which is even worse than coal- the total amount of carbon dioxide emitted is half that of the most efficient gas-powered cars. They have no tailpipe which eliminates emissions (again this is as long as the energy source is renewable).
  • They take no gasoline but rely on electricity from power grids and other forms of renewable energy such as windmills, solar panels, and so on.[3]
  • Aids in reducing urban air pollution.[4]
  • The batteries don't contain as many heavy metals as conventional cars. One well-known American luxury electric car manufacturer who make their own batteries uses aluminium - instead of manganese cathodes (that are used in every other production electric car in 2018).
  • Electric vehicles require almost none of the maintenance of conventional cars like oil changes and emissions check. Electric vehicles can provide nearly 1 million mills of service before needing maintenance.[5]
  • Noise pollution is reduced, especially in major cities. Electric vehicles have no muffler and there is no need for one because there is no engine, or ignition, so it has nothing to muffle. The cars are almost completely silent.
  • Reduces the dependency on foreign oil and the entire military infrastructure that is used to protect oil wells,pipelines and refineries. Purely electric vehicles take no gasoline, but uses alternative energy sources to generate electricity. One day in 2016 Germany produced 87% of its needs from renewables. All that was electrical energy, which is useless in a gasoline car.[6]
  • Lower costs: lower operating costs, lower maintenance costs and higher efficiency, plus exemptions from stamp duty and lower registration fees in some countries and states.[7]

Battery EVs are cleaner[edit | edit source]

There are also hydrogen fuel-cell vehicles you can look into. Yet hydrogen is a gas and as the name itself suggests. Of course, you can go for a plug-in hybrid as well. For that's the switch to burning petrol once your battery gets low. However it is still not the greenest option available.

Of course, we also have to note that running on electricity is still not completely green. Yet in most state's it's pretty darn green.

Electric cars represent the most environmentally friendly car fuel, as they have absolutely no emissions. The energy generated to power the electric car and the energy to move the car is 97 percent cleaner in terms of noxious pollutants.[8]

Lithium-ion batteries, which store three to four times more energy per unit mass than traditional batteries, are now used extensively in portable electronic devices (computers, cell phones, MP3 players, etc.). The positive electrode materials in these batteries are highly effective but too expensive to be used in the large batteries needed for electric vehicles and second generation hybrid vehicles. In the future, these applications may rely on lithium iron phosphate: it is environmentally friendly and has exceptional properties combined with low cost and good thermal stability (important for safety reasons). All these qualities make it the best candidate to be used in lithium batteries for future electric cars.[9]

History[edit | edit source]

Fig:1 Who killed the electric car?

Electric propulsion was first used in vehicles other than cars. The locomotive was the first fully electrical vehicle and was created by Werner Von Siemens.[10] The first fully electric type of transport in US America was a rail operation in 1888 created by General Electric.

By the year 1891 a man named William Morrison put an electric motor in a car. Electric cars were supposed to be the car of the future and got a lot of attention in the 1890's and early 1900's.[11] However due to a breakthrough in internal combustion engines, cars that used gasoline ruled the 1900's. Now in the 21st century, hybrids and electric cars are making a comeback due to the push for green modes of transport and current high prices of petrofuels (gasoline, Diesel, LPG,...).

Types[edit | edit source]

Types of electric cars.[12]

There are different types of electric cars. Some have only one engine, which is (of course) electric. The problem is, that the range of such a car is still quite short. In the future, when battery-technology is better and batteries' capacity will be higher and the costs will be lower, pure electric cars will be more popular.

In order to increase the range of these electric cars there are different types, such as hybrid cars. These are vehicles use a technology that combines electric and combustion engines. The ways, how combustion engines are used in these cars, are different:

  • The combustion engine produces energy to run the electric engine. In these technology the fuel-driven engine is used as a generator.
  • The combustion engine is only used, when the car accelerates strongly. So the car needs no fuel when you drive slowly or break. This system is called "Series Drivetrain"
  • The electric engine is only used when the car accelerates. When the car drives slowly or you cruise, energy from the engine gets stored in the battery. You call this system "Parallel Drivetrain".
  • When you drive slowly, only the electric engine is used. When you accelerate, the fuel-driven engine engages, but not all its power is transferred to the gear: A power drives the gear and a generator that produces electric energy, which is stored in the battery. This technology is called "Series-Parallel Drivetrain".

These different technologies also have some similarities: they use the energy of the breaks. So the engines are used as generators when the car slows down. The produced energy can be stored in the battery and the range of the car increases a bit.

Battery-electric cars[edit | edit source]

Inside of electric cars.[13]

Battery-electric cars are in a class of their own when it comes to saving gas. Due to the fact that it's uses only a battery to power the electric motor,[14] it uses no gas. The distance you can travel with it greatly depends on the load, and speed. You will need to use more energy on heating (but much less on cooling), which reduces the miles range. Depending on how much it has to carry, the load will affect how hard the battery has to work. If you like to go fast, don't expect to go far. Like most cars, BEV's can travel further at a controlled comfortable speed. That range depends on the model. The definitive guide is, what is the KWhr battery:curb weight (Kg) ratio. A good ratio is 0.020; a bad one is.036. A bad one tells you that the car has not been designed originally as an electric.

Currently, advice from manufacturers is that extension leads cannot be used for charging at a normal household outlet. This is not true. Normal extension leads use twisted copper for flexibility. However household wiring cable can be used for charging. A 30 Metre cable for an 12 Amp 240V load is possible, however, household wiring cable is not designed to be handled regularly, as it is stiff, so use large loops of it and handle it carefully to avoid any kinks in the cable. Alternatively, use a heavy duty extension cable. A very useful amount of charge can be gained in just 2 hours. Use the BEV user manual to estimate how much extra range you will get.

BEV's (Plug-in cars or Electric cars). They are simple in construction (one Californian company uses 10K parts [25-30K parts in a conventional car]) and like a DVD drive or laptop battery, need little maintenance; brakes are not used as much as in a gas car as there is considerable braking effect when the vehicle re-generates while slowing down. Servicing costs are much lower than gas cars (which typically have 20-30,000 parts), especially as the vehicle ages. Various battery leasing schemes are available that typically guarantee a 80-90% performance. My car has 85k miles and has not needed any parts (apart from tyres & windscreen wipers & a12v lead acid battery [$70]). Its RANGE is the approximately 15% less. Range can be improved by gentle (not slow) cornering & taking a warm coat instead of using the heater and the tyre pressures MUST be correct, not low. All BEV cars (2020) have fast charging (7-22kW) capability which provides 20-30 miles per hour of charging. Vehicles are the simplest of all cars to drive & every passenger says how silent and trouble-free the experience is. Many drivers say BEV's have put the fun back into motoring.

Approximate costs

Purchase costs are higher than a gas car but this is offset by very low running costs (approximately 1/6th that of the most efficient gas car). A typical UK micro hatchback Electric car in the UK (if the decision is to throw the car away after 10 years) is likely to save £6500 over a similar gas car (on a 10,000 mile per year basis). After the decade, the range will very gradually reduce, but the servicing savings will be even more beneficial. Various local schemes exist for free parking in cities, and over 185,500,000 lock-able electric points are listed (2020) on [1]. There are 37,500 public charge points -more than gas stations-in the UK (Jan 2021). Slow rate charging (3kW) is often supplied in unlimited amounts in the UK for a monthly payment (usually approximately £20 -2020).

Fast rate charging (7-22kW) & rapid (25-99kW) charging is costed at a kWhr rate by the supplier & provides 50+ miles extra range per hour of charging. There are 7,850 UK rapid charging points (2020) allowing 'empty to full' for a mid-sized BEV in approximately one hour.

Green issues

The CO2e for manufacture of a conventional mid-range petrol car is approximately 17 Tonnes; for a traditional car manufacturer converting an existing petrol model to electric, it is approximately 10-15 Tonnes; for the newest only-electric car manufacturer from the USA, it is 5.1 Tonnes (most of the manufacturing is with renewable energy).

To have guilt-free motoring it is possible to buy renewable power, marginally more expensive but those costs have already been factored in above.

Conventional hybrid-electric cars[edit | edit source]

Hybrid-electric cars[15] use both gas and electricity to propell the car. Cars running on a IC engine ('ICE') typically use a lot of gas at times when they come to a stop or pick up speed after a stop.[16] The electric motor is used to eliminate the siphoning of gas at these particular moments. In a (series-)parallel hybrid-electric car, the electric motor is used when a car is idle until a speed of 30- 40 mph. Past 40 miles, the other half of the hybrid system - known as the internal combustion engine - takes over. This is a switchable function. The hybrid gets its name from being able to use both the electrical motor and the combustion engine. It may also charge the battery by using the kinetic energy from braking and redirecting that energy back to the engine. An example of a hybrid would be the Toyota Prius.[17] In terms of CO2e for manufacture and use ('well to wheel'), all hybrid cars have little environmental benefit, most of the benefit is in fuel saving and reduced pollution in cities. They are complicated to service, so a reliable brand is recommended.

Plug-in hybrid-electric cars[edit | edit source]

Plug-in hybrid-electric cars are a subdivision of the hybrid-electric car. PE-cars (Plug-in hybrid cars) have a slightly larger battery than hybrid cars. MOST HAVE AN ELECTRIC RANGE OF 20-30 MILES. A longer charge making it possible to avoid using the internal combustion engine for a few miles more.[18] As long as the car isn't used passed the point of its all-electric range, the Plug-in hybrid is able to avoid using any petrol at all. Large hybrid cars are less environmentally friendly than a very small gas car in terms of fuel consumption and a number of studies show that the electric motor is used between 5 and 20% of the travelling time. One criticism of this class of vehicle concerns the charging time. THE MAXIMUM CHARGE RATE OF ALL HYBRID CARS IS ONLY 3KW. (That is 1/75th the rate of the fastest CCS or Cha de Mo charging stations. The hybrid-electric car is designed to be charged at night, not at public points because a plug-in hybrid can occupy a slot for 4 times as long as a fully electric car needs on a MEDIUM speed (7-25 KW) point. Additionally, a fully electric car will benefit from 5times the range in the same period of time. A number of manufacturers who are entering the market with VERY HEAVY conventional cars with a small added battery and small electric motor seem to pay 'lip-service' to green principles. Servicing for an old hybrid car will be very expensive because of the unnecessary complexity.
