  1. Samsung Battery Breakthrough Fast Charging and 45% Capacity Increase Samsung NewsRoom Announcement SAIT (Samsung Advanced Institute of Technology) has announced a breakthrough in developing a graphene ball coating that covers the nickel-rich cathodes and lithium-based anodes. So one would ask what is the big deal? As you increase the speed of recharging a battery, it wears down the anode and cathode. The graphene ball coating not only prevents this, but also allows for an increase in capacity to go along with the faster recharging. This improves the cyclability of charging / depleting a battery. This tech also has proven to allow for a very highly stable battery with no loss of power at 60 degrees Celsius or 140 degrees Fahrenheit which is key for any electronic device but even more so for electric auto's. Graphene is 100 times more effective than copper in conducting electricity and 140 times times faster than silicon. Samsung says this technology allows them to take a conventional EV battery that would require 4hrs under current fast charge technology and reduce it to 12 minutes. To quote their new release: "SAIT’s research results are covered in-depth in this month’s edition of the science journal Nature Communications in an article entitled, “Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities.”SAIT has also filed two applications for the “graphene ball” technology patent in the US and Korea."
  2. G. David Felt - Staff Writer Alternative Energy - www.cheersandgears.com West Coast Electric Highway Expands to 7 States for Fast Charging Arizona is the latest state to join the newest 7 member states that will expand the original West Coast Electric Highway system. Originally Washington, Oregon and California got together to build the West Coast Electric Highway at a cost of $257 million dollars to the taxpayers. This enabled anyone with an electric vehicle to drive from Vancouver BC to Baha California on I-5 in an electric vehicle. Since then, these states have expanded their EV chargers across state highways giving greater range to anyone driving an electric auto around. Since then more states have assessed the future and decided on joining this to cover a larger interstate electric highway system. At the beginning of this year Colorado, Nevada and Utah said they would build out over the next 24 months a 2,000 mile electric interstate charging system of fast chargers. This summer say Idaho, Montana, New Mexico and Wyoming join effective October 4th 2017 and here the week of October 20th 2017 we see Arizona join to grow the electric highway to over 5,000 miles of interstate that will have fast charging available by the end of 2019. This on top of the thousands of miles of the original electric highway is growing exponentially the change that is coming to EV auto's. All of these states are looking at investing their VW settlement funds into the electric highway initiative. Colorado alone says their $68.7 million dollar payout by VW will enable them to cover the whole state with Level 3 fast chargers leaving room for the extreme fast chargers to be installed by others who are willing to pay for an even faster recharge of their battery packs. The fast charging stations will cost between $150,000 and $200,000 per station installed all over the state. At the high end, this would mean Colorado alone will install 343 fast charging stations across the state. Colorado Governor has also announced a $5,000 tax credit for new EV auto purchases on top of the Federal tax credit of up to $7,500. This means buyers can get a credit of $12,500 against the purchase of an EV auto. The political representatives for these states point to announcements from General Motors of 20 electric auto's by 2023, Ford with 13 electric auto's by 2020, Mercedes-Benz with announcing an electric or plug in hybrid for each model in it's family by 2022.

  3. G. David Felt Staff Writer Alternative Energy - www.CheersandGears.com EVgo Partners with Nissan and BMW Again to Expand DC Charger Network According to the latest release this week by EVgo, a leader in EV charging systems for home, work or public use, they have partnered up with Nissan and BMW to expand coast to coast the DC fast charging network offering both CHAdeMO and SAE Combo (CCS) connectors allowing ALL EV types to charge on the fast charge network. These are 50 kW DC fast charging systems. EVgo currently has 668+ DC fast charging systems across the U.S. This partnership will allow them to expand across the US supporting all EV auto's for charging through 2017. 50 more fast charging system will be added in 2017.

  4. G. David Felt Staff Writer Alternative Energy - www.CheersandGears.com Samsung, The Next LG Battery Competitor? Samsung has decided to be the next major Li cell supplier to the auto industry and has decided to one up LG in their quest to be the top supplier of super high density Li cells. Back in September 2016 Green Car Report stated that in an interview with Samsung, that they wanted to be equal to if not replace LG as one of the largest Li cell suppliers to the auto industry. They currently supply the cells for the BMW i line of EV auto's. In this story Samsung announced a $400 million investment in a new battery plant in Hungary which would allow them to support the growth of BMW's EV auto plans into the next century. Samsung pointed to LG's leadership in supplying batteries to 25 top tier auto companies around the world which includes GM's latest darling the Chevrolet BOLT. In this story, it is stated that both LG and Samsung will supply Audi with cells for their Audi EV SUV that is slated to be out in 2018 as a 2019 model. It also states that Samsung has bought a 4% stake or $449 million dollar investment in Chinese auto maker BYD which to quote the story; " BYD produced more electric cars and plug-in hybrids than any other company last year, although only a small fraction were sold outside China. " Clearly Samsung is wanting to be at the leadership position of the EV revolution and is willing to invest in making sure they get the sales. Fast Forward 4 months to an updated story by Green Car Report which is based on a story only days earlier by techcrunch.com that Samsung has a new battery cell design that allows near full recharge in 20 minutes. This is not some lowly 50 to 70 miles, but based on their new cell design and the battery pack they have built which is equal to 372 miles, this battery pack would give you 310 miles as a quick charge in 20 minutes. The story states that Samsung's new battery design is 10% less cells and weight versus current battery production from SDI. Now Samsung does not state if this quick charge is based on existing DC charging or what the industry is calling the new XFS charging system. XFS stands for Extreme Fast Charge and is designed to handle a minimum of 350kWh charging or more. Energy.gov web site has stated that they are working with the auto makers and their own researchers to make a standardized system that can handle the heavy power safely for the public so that the energy load is balanced, reduces cost as well as mitigate time to charge issues on top of cybersecurity concerns about paying for the use of these XFS Charging systems. XFS Charging Station concept by Electrek End result to quote the Energy.gov web site post: " Extreme fast charging is poised to accelerate mass market EV adoption as DOE and industry stakeholders work to overcome technical, cost, and safety barriers. Implementing an XFC system capable of up to 350-kW charging has the potential to increase EV utility, which in-turn would provide Americans with greater freedom of mobility and energy security. "
