ELECTRICAL ENCYCLOPEDIA

Battery as an Electrical Source   An electrical battery is one or more electrochemical cells that convert stored chemical energy into electrical energy. Since the invention of the first battery (or "voltaic pile") in 1800 by Alessandro Volta, batteries have become a common power source for many household and industrial applications. According to a 2005 estimate, the worldwide battery industry generates US$48 billion in sales each year, with 6% annual growth.. continue.. Battery Types Available for Use   There are two types of batteries: primary batteries (disposable batteries), which are designed to be used once and discarded, and secondary batteries (rechargeable batteries), which are designed to be recharged and used multiple times. Batteries come in many sizes, from miniature cells used to power hearing aids and wristwatches to battery banks the size of rooms that provide standby power for telephone exchanges and computer data centers.. continue.. How Batteries Wor...

Elements of Car Conversion   Almost any vehicle can be converted to electric. Many people prefer to pick a vehicle that is light and aerodynamic in order to maximize distance traveled per battery charge. There must also be adequate room and load capacity for batteries. The battery pack, which provides a source of electrical power. The most commonly available and affordable batteries are lead-acid flooded type. Next are the AGM (Absorption Glass Mat) sealed maintenance free batteries, a little more powerful and expensive. Then there are the more exotic batteries like Ni-MH and Li-ion; more difficult to find but light and longer lasting, maintenance free, and much more expensive. The new lithium batteries are showing some promise for EVs in the near future. The charger which restores energy to the batteries (which may be mounted within the vehicle or at a special charging station at some fixed location) The power controller, which regulates the flow of energy between the battery ...

What is an Electric Car?   An electric car is an automobile which is propelled by electric motor(s), using electrical energy stored in batteries or another energy storage device. Electric cars were popular in the late-19th century and early 20th century, until advances in internal combustion engine technology and mass production of cheaper gasoline vehicles led to a decline in the use of electric drive vehicle. The energy crises of the 1970s and 80s brought a short lived interest in electric cars, but in the mid 2000s took place a renewed interest in the production of electric cars due mainly to concerns about rapidly increasing oil prices and the need to curb greenhouse gas emissions.. continue.. Battery Powered Car   Electric Cars use the energy stored in a battery (or series of batteries) for vehicle propulsion. Electric motors provide a clean and safe alternative to the internal combustion engine. There are many pros and cons about electric cars. The electric vehicle ...

What is an Electric Vehicle?   An electric vehicle (EV), also referred to as an electric drive vehicle, uses one or more electric motors or traction motors for propulsion. Three main types of electric vehicles exist, those that are directly powered from an external power station, those that are powered by stored electricity originally from an external power source, and those that are powered by an on-board electrical generator, such as an engine (a hybrid electric vehicle), or a hydrogen fuel cell.. continue.. Plug-in Hybrid Electric Vehicle   By using electric power most of the time and batteries are recharged by plugging into the electrical grid, PHEVs can reduce the use of fuel and lower the cost for fuel. Owners of PHEVs can recharge their vehicles at home, which can also limit their trips to the gas station. Even though the actual cost still depends on how the car is driven and the owner's driving behavior, the overall cost is lower than conventional cars due to the ...
