The Electric Car: Gen Chem 142 Lab
Transcript of The Electric Car: Gen Chem 142 Lab
1. Tesla Model S:
2. Nissan Leaf: The Tesla 3 Battery Options
85 kWh 60 kWh 40 kWh
300 mi 230 mi 160 mi Charging Tesla mobile connector plugs into 110v and 240v outlets 110v
5 mi per hour of charge 120v
31 mi per hour of charge High Power Connector
62 mi per hour of charge Nissan Leaf Range 24 kWh Battery = 130 mi Charging Reaches full charge overnight
Convenient On-The-Go Charging Stations Battery Made of 1 or more electrochemical cells
Each cell is made of a negative and positive electrode
Electrons flow from the negative electrode to the positive electrode when connected with a wire.
This reaction can be reversed by adding current from an outside source (only in rechargeable batteries). hyperphysics.phy-astr.gsu.edu Electric Car Batteries There are 3 suitable batteries for EVs
nickel metal hydride (NiMH)
There is work to develop a Li-ion polymer battery
Also work on a 500 mile per charge lithium-air battery http://www.sgate.com/bayarea/article/Tesla-to-build-new-electric-sedan-in-Bay-Area-3278560.php#next Electric Motors Motor uses magnets to create motion
Attracting and repelling forces create
Armature (rotor) is an electromagnet http://static.ddmcdn.com/gif/motor-labels.gif Driving Controller delivers power from batteries to the motor
Accelerator hooks to potentiometers (variable resistors)
These signal the controller how much power to deliver http://static.ddmcdn.com/gif/electric-car1.gif http://static.ddmcdn.com/gif/electric-car2.gif WQQ Questions? Starting at $52,400 Starting at $35,000 The Market Pros Cons Technology Pros Cons Market optimism
GM's 500,000 by 2017
More people are "going green"
Decreasing EV costs
Possible investments Innovations in lithium ion battery technology will allow for cheaper and more efficient batteries and cars Uncertainty in the less affluent market
Car company promises have been broken before
Less than 50,000 EVs were sold in 2012
Electric car maker, Fisker, in financial trouble Technological improvements have been occurring very slowly due to low demand Cheaper batteries would allow more of the population to purchase EV's creating demand for car companies Low demand and lagging technology have caused many battery producers to exit the market EV's need to become more appealing to buyers to have more of an impact on the market http://www.gravitatechnomech.com/Lead-Metal/usesofLead.html http://www.treehugger.com/clean-technology/lithium-air-battery-could-have-up-to-10x-storage-capacity-of-current-lithium-ion-tech.html http://www.carseek.com/articles/hybrid-car-batteries.html Market Optimism http://www.gaston-lithium.com/tech-certificates.html http://www.gaston-lithium.com/tech-certificates.html Base price comparison:
Ford Fiesta = $13,000-$18,000
Nissan Leaf = $35,000
Financially, is it worthwhile for average American to go green?
Owners have to replace $10,000 battery every 100,000 miles Tesla Model S set the Record for EPA Range Tests for EVs Sources http://www.teslamotors.com/goelectric

Pros Cons Efficient
Electricity is less expensive
Cost of productions is decreasing How it works Although great for the environment by reducing greenhouse gas emissions, EVs are not yet cost effective with the currently available technology Conclusion http://www.teslamotors.com/goelectric#savings http://www.bmwblog.com/2010/10/10/bmws-green-driving-assistant/ http://www.zapworld.com/node/179 http://www.fastcashforjunkcars.com/blog/2013/01/futuristic-electric-cars/ http://ecomerge.blogspot.com/2013/02/boeing-787-and-electric-car-lithium-ion.html http://www.dunntireblog.com/5-tips-on-how-your-vehicle-can-reduce-emissions http://www.bloomberg.com/news/2012-11-01/tesla-s-102-000-electric-model-s-surges-like-a-supercar.html http://www.nydailynews.com/autos/tesla-launches-supercharger-station-electric-cars-rapid-charging-long-distance-trips-article-1.1167685 http://en.wikipedia.org/wiki/File:Nissan_Leaf_005.JPG http://wot.motortrend.com/electric-deal-certain-nissan-leaf-dealers-offering-nearly-10000-in-lease-cash-incentives-308223.html/revised-nissan-leaf-japanese-spec-interior1-2/#axzz2M3ROiCxu http://www.downtownbellevue.com/2010/06/24/city-bellevue-prepares-electric-vehicles/ http://www.youtube.com/watch?v=yJyVTd_O-vwx http://www.youtube.com/watch?v=0HO6tYN3w5Qx http://www.youtube.com/watch?v=r0b8zC96i9Ix http://www.exterro.com/e-discovery-beat/files/2012/12/Efficiency.jpg http://goodmenproject.wpengine.netdna-cdn.com/wp-content/uploads/2013/01/car-exhaust_GMP-588x356.jpg http://www.reports-research.com/fileadmin/user_upload/Grafiken_PM/Hybrid_Electric_Car_Market__Global__by_Volume___000___2000_2015.jpg http://www.extremetech.com/wp-content/uploads/2012/01/Nissan_Leaf.jpg
