    Cycle World electic power articles

    It looks like Kevin Cameron, the Cycle World magazine tech guy, is starting a series of electric motorcycle power articles. Here is the first installment:

    And finally, Part 5 of the series in which Mr. Cameron discusses Li battery technology and a little about its potential future:

    Great stuff, thanks for posting it.

    Couple things on the last piece. He forgot to mention Nickel-Manganese-Cobalt (NMC), the most widely used chemistry in production electric cars and motorcycles. It has almost entirely replaced LCO and LiFePO4. I believe Tesla is the only company still using LCO or NCA, the two most volatile chemisties.

    He also said that LCO needs a BMS to keep them safe. True, but every lithium cell type needs a BMS to maintain it. No major manufacturer sells an EV without a BMS, regardless of the lithium chemistry. The only EVs without a BMS are DIY projects where the builder maintains the cells "by hand".

    People have mostly given up on Li-air. The big "next things" on the horizon are solid state electrolyte cells, Li-sulfur, and Sodium-ion. Some labs are toying with graphene as an anode material.

    I too appreciate the posting of these articles...Thanks Richard.
    Reading some of the comments below each article was entertaining also.
    There will always be naysayers and negative people unwilling to accept the fact that we live in a very rapidly evolving world.
    Personally, I remain optimistic and look forward with anticipation to all new developments in this fascinating story! Proud to be part of it!!
    But still happy riding my ICE vehicles too!

    I think it is going to be a tough year for EV sales due to the low gas prices and manufacturers making more efficient vehicles (well, maybe not efficient motorcycles). On the other hand, IC vehicle prices are climbing steadily each year and it is only a matter of time before they cross EV prices, which are slowly coming down. Plus, when the Saudis finally put enough oil producers out of business, gas prices will go up again and EV's will look more appealing to the general public.

    The Cycle World EV series of articles may not have been perfect, but I do believe they give a good overview of electric propulsion for most of their readers who may know little about the subject.
