Electric Car/Vehicle Battery By EuclionEnergy Private Limited
What is Electric Car Battery • The electric car is basically a machine that operates on Electric Car battery. Instead of the conventional gasoline engine, you have components powered by electrical energy. The car moves by the power supplied by this electric energy. • The single most important component in the electric car is the battery. It provides the motive force aside the powering of electrical components like the wiper, headlamps and horn. • We take a look at the battery system of the electric car which looks and works in a much different way from that of conventional vehicles. • First, there are several types of Electric Car Batteries. We have the AC brush less which provides high speed but has the limitation of poor acceleration. Next comes the AC induction which also gives high speed and high acceleration but is the most expensive to buy. Many electric cars use the economical version of batteries called the Permanent magnet which provides average performance.
EV Battery Requirements • Safe • High Power • High Capacity • Small and Light • Large Format • Long Life • Low Overall Cost
EV Battery Types.. Lead-acid • Flooded lead-acid batteries are the cheapest and most common traction batteries available. • There are two main types of lead-acid batteries: automobile engine starter batteries and deep cycle batteries. • Traditionally, most electric vehicles have used lead-acid batteries due to their mature technology, high availability, and low cost. • Lead-acid batteries in EV applications end up being a significant (25–50%) portion of the final vehicle mass. • The efficiency (70–75%)
Nickel-metal hydride • They boast an energy density of 30–80 Wh/kg, far higher than lead-acid. • When used properly, nickel-metal hydride batteries can have exceptionally long lives. • Present NiMH,RAV4EVs that still operate well after 100,000 miles (160,000 km) and over a decade of service. • Downsides include the poor efficiency, high self-discharge, very finicky charge cycles, and poor performance in cold weather.
Lithium Ion Battery • The traditional lithium-ion chemistry involves a lithium cobalt oxide cathode and a graphite anode. • This yields cells with an impressive 200+ Wh/kg energy density and good power density. • 80 to 90% charge/discharge efficiency. • Silicon nanowires, silicon nanoparticles, and tin nanoparticles promise several times the energy density in the anode.
Examples of EV Using Different Batteries Using NIMH Battery • The General Motors EV1 had a range of 75 to 150 miles (240 km) with NiMH batteries in 1999.
Conclusion • Electric Battery Automobiles are really important as they will prevent a major source of increased Global Warming and other natural problems. • New Concepts of rechargeable should arise that will have higher efficiency than all other existing batteries.
