Electric Vehicle Range – The Role and Care of Your Batteries

With the right motor and batteries you will be surprised at the acceleration ability of your new electric vehicle. You will even out accelerate many gas vehicles if put to the test. We are not just building an oversized underpowered golf cart here. These vehicles are capable of doing 50 mph and have a range of up to 200 miles before they need to be charged up.

Depending on whether you have bought new batteries or found some second-hand industrial batteries you will have to decide how you are going to maximize their lifespan and the range you are going to get out of each charge. With second-hand batteries you may need to be more conservative with your speed and range. Most second-hand batteries can be restored to almost new condition with some care, with flooded batteries this would involve emptying the batteries of electrolyte and filling them up again with ionized water and then charging them for approximately 24 hours. When they have been charged like this they are emptied once more and the process is repeated, they should then be refilled with the correct electrolyte and charged once more.

This process should give them a totally new lease on life. With new batteries, they take time to reach full capacity, usually after a number of charges, and most batteries should not be run to fully discharged early on as this will reduce their lifespan. Because the batteries are the heart of your electric vehicle and determine how far you will be able to travel on a single charge, it is essential to take good care of them, whether they are second-hand batteries which you picked up cheaply or a new set of batteries which you paid good money for. If you have been able to buy a new set of batteries it is highly advisable to carefully read the instructions which would come with the set as these instructions will give you the best advice on how to best care for your new batteries, thereby ensuring you get the maximum usage out of the batteries.

As you get used to driving your electric vehicle, you will find ways of running without using the motor, such as when there are steep hills, you can often coast down the hills to save the batteries. This will significantly increase your range and remember that when you are doing this you are saving money and doing your bit to help the planet.

Battery Electric Vehicles

Cars are one of the most commonly used vehicles for commuting and since the origin of the automobiles, there have been various innovations in terms of types and kinds of cars. One of the earliest among these characteristic kinds was the electric cars or EV, also known as the battery electric vehicle or BEV which emerged in the 19th century. Unlike the hybrid vehicles which perform with the aid of both internal combustion engines as well as electric motors, the electric cars make use of motor controllers and electric motors and function by means of the chemical energy stored in rechargeable battery packs. With the progress of time and advancement of technology, one of the adverse effects that hit human civilization was the ill-effects of pollution.

Under such circumstances, it must be pointed out that battery electric vehicles more often make use of renewable sources of energy and therefore they do not emit exhaust fumes and minimize the risks of environmental pollution. These electric vehicles do not produce toxic smoke and are mostly soundless and are also capable of producing more acceleration compared to the conventional vehicles. The different variants of the battery electric vehicle include golf carts, electric scooters motorcycles, light trucks and because of their low dependence on the use of petroleum, it is possible to constrict the harmful effects of global warming as well. The most important constituent of the battery electric vehicles are their batteries and in mot circumstances, the prices of the batteries determine the expense to be incurred by the owner on the vehicle. However, they are still considered to be cheaper compared to the conventional vehicles and while the initial battery prices may seem high, the overall maintenance cost is not that expensive.

There are several reasons why the battery electric vehicles are more often a preferred option among enthusiasts. The fluctuation of rising fuel prices does not affect it and they are also successful in restraining vehicle energy costs by almost 90%. The source of electricity in ca battery electric vehicle may be obtained form hydro power, solar power, wind energy or nuclear power which ascertains the non-emission of carbon fumes which can cause harm to the environment. Batteries need to be recharged after stipulated priors of time and those costs are not so high and remain more or less constant compared to the inconsistency of fuel prices.

However, it is to be kept in mind that unless renewable sources of energy are used, electric vehicles cannot check carbon emissions and the batteries too require frequent replacement.

Hybrid Electric Vehicle – Down to the Parts

With all the great news from the auto industry introducing another hybrid vehicle or another electric vehicle, this article explores a bit what such vehicles are made of. What are the differences with the conventional petrol car and what might the future hold for them?

The first difference you see these days is that both the electric vehicle and the hybrid vehicle come with a plug to charge it at home; the conventional vehicle has not. The conventional vehicle also has no electric engine to power the wheels or a large battery to power this engine. The conventional car of course does have a battery, but that is just used for starting the internal combustion engine and it acts as a buffer for the electrical systems used. Power in the conventional vehicle is generated by the combustion engine.

For an electric vehicle, there are two main components: the electric motor and the battery. The electric motor is the one to power the wheels of the vehicle and the battery is used to bring along energy for the trip. They almost all have the option of regenerative braking, which allows one to recover energy when slowing down and charging the battery a little while doing so. This is a great method to increase the overall efficiency for a vehicle! Further more there is often a special battery management system (BMS) which ensures the battery is kept at the right temperature and is not charged or discharged in a way that can damage the battery.

For a hybrid vehicle there are a few more main components: besides the electric motor and the battery, there is also an onboard power source like the conventional combustion engine (but also a fuel cell is used for example). Additionally, there is a system that somehow connects the power from the battery and the for example combustion engine and gets it to the wheels. There are many ways to do this last step, the simplest being that the combustion engine would be used as a generator to power the electric motor with electricity. Excess electricity is stored in the battery for future use. Another method is to have a special gear set combine the mechanical power from the combustion engine and the electric engine and get them to the wheels. There are also manufacturers who power one set of wheels with the combustion engine and the other set of wheels with the electric engine. A big advantage of the hybrid vehicle is that it can use the very efficient electric engine at lower speeds (for example urban areas) and the combustion engine for extra power on the highways or for extra range.

To sum it up, an electric vehicle consists of:

– Electric Engine
– Battery

A hybrid vehicle consists of:

– Electric Engine
– Battery
– Energy source (internal combustion engine, fuel cell, etc)

The disadvantages of the electric vehicle and the hybrid are mostly the cost. Compared to the conventional car they can cost more to purchase. This has two main reasons; the first being that the conventional car is mass-manufactured which makes it cheaper (compare one million units produces versus one thousand units produced) and the second is the current price of batteries. Batteries at the moment are the biggest cost within the vehicle, the larger your battery is, the larger the cost is in the total price of the vehicle.

Another disadvantage which currently mostly applies to the electric vehicle, is the range it can cover. Current vehicles are of such a weight and their batteries can only hold a certain amount of power. Comparing the electric vehicle to a conventional petrol car they can cover a lot less ground on a full charge or tank. The first argument to counter this disadvantage is that most people do not drive distances that can not be covered by an electric vehicle. Current electric vehicles can cover about double or four times the daily distance required by many people! However, there are three movements currently helping to overcome the range anxiety problem. The first is the battery manufacturer, which improves the technology so that the battery will weigh less and can contain more power. The second is the charging industry, where solutions are found in fast charging. Conventional charging can take up to eight hours to charge your vehicle. The goal is to reduce this to an acceptable amount of mere minutes. The third force is heading for battery swapping; much like a petrol station, an electric vehicle can swap the empty battery for a fully charged one.

For the future of the electric vehicle and the hybrid there are many options, the most popular ones are:

– Fuel Cells
– Fast Charging of batteries
– Better batteries that weigh less and hold more power
– Battery swapping stations
– New car design options

Lots to expect from the electric vehicle and the hybrid vehicle!
