  • A Couple Graphs From Axion Power's Presentation At The Battery Show

    Last week I got my copy of the and presentations from The Battery Show in Novi, Michigan. Since the participants paid several hundred dollars a day to attend it would be improper for me to publish complete presentations without permission. I can, however, share a couple of graphics from Axion Power International's (OTCQB:AXPW) presentation that impressed me and may be interesting to readers.

    This first graph is Axion's presentation of the battery performance data collected by ePower Engine Systems that I smoothed to 20-second intervals for my July 12, 2014 Instablog titled Latest Update From Jay Bowman.

    The second graph is an updated version of the long string behavior analysis that we first saw in late 2012 which compares the stability of a 24-battery AGM string with a 24-battery PbC string. While the 2012 slide presented 120 days of data for both battery strings, the new slide presents 120 days of data for the AGM string and about 670 days of data for the PbC.

    The things I find extraordinary in this graph are:

    • The right hand axis, which presents the standard deviation of module voltages, is scaled more tightly on the PbC graph than it is on the AGM graph;
    • While the AGM string had eight battery replacements in 120 days, the PbC only had three battery replacements in about 670 days;
    • Sticking a brand new battery into a 24-module string of old batteries would typically cause a variety of problems, but the new PbC's seem to integrate smoothly; and
    • The graph suggests that the test protocol contemplated a two-shift duty cycle.

    Since ePower hasn't had the opportunity to test the PbC for almost three years, we find the long term string performance data very comforting and believe the ability to do single battery replacements instead of replacing a full battery pack will be very appealing to our customers.

  • Jay Bowman's Latest EPower Update

    The following is an unedited version of Jay's recent update to ePower investors.

    We attended The Battery and Electric Hybrid Vehicle show in Novi Michigan this week. Our truck was received very well by everyone who stopped by the booth. We had steady traffic for the three days that the truck was on display. Our visitors ranged from governmental agencies, engineers from Chrysler, General Motors, Ford, Toyota, Tesla and several national labs. I also met with people from Cummins, Eaton and other existing or potential suppliers. We had representatives from Axion Power, our battery supplier, helping on one of the days we were showing the truck. We also met with Axion Power to discuss battery warranty length and terms. These discussions should reach a conclusion this week that will contain favorable and acceptable terms for our customers who will be using our drive train. The reason we decided to show the truck at this particular show was that ePower was invited to be a speaker at the battery conference. This job fell to John Petersen to describe what we are developing and the advantages of our system. John was preceded by Eaton Corporation and followed by Axion Power International. John did an excellent job of presenting our technology and captivating the attention of the attendees. Following Johns presentation we saw an increase in traffic to our booth by many impressed individuals. Below you will find links to the slide presentation and script that John presented at the show.

    As you can see we are starting to sharpen our message to the market. We will begin approaching fleet owners over the next three months with our truck and a compelling reason for them to accept our solution. Our message was well received by all who attended the show and most believe it will be a message that has the potential to change the type equipment used by the trucking industry. We are on the leading edge of this technology and in a position to reap the rewards of the hard work and determination we have all put into this project over the last 5 years. I want to that thank all of you for your present and past support. I would also like to thank Bob White one of our investors who came to help at the show at his own expense. Also without Mario's and Andrews hard work we would not have had the truck ready for the show and they both did an very professional job of explaining to people what we have and why it works over the last three days. All in all it was a great week for ePower and our combined futures.

    Please contact me with any questions or comments. Thanks

  • My Presentation For The Battery Show

    As many readers know, I will be doing a presentation on the ePower Hybrid at The Battery Show in mid-September at the Novi Center in Detroit. Mike Romeo of Axion Power International (OTCQB:AXPW) will be doing a follow-up presentation on why the PbC® battery is an ideal solution for our drivetrain.

    Both presentations are scheduled for September 17th in the 8:45 to 10:30 Session that will focus on Business Models and Technologies for Transport, Commercial Vehicles, Trucks and Heavy Hybrids.

    Since speakers will be limited to 15 minutes at the podium, a good presentation has to be brief, informative and understandable. Since I've always found longer documents easier to write than short ones, I've spent a lot of time keeping this presentation brief and I would truly appreciate constructive comment from fresh eyes.

    I've posted a draft of the presentation to my DropBox and you can download from this link.

    The rules of the game at this point are pretty simple.

    • I can't add words without taking an equal number of words off a page; and
    • I can't add slides without increasing the risk that I'll run out of time.

    My primary goal in this exercise is making the presentation as good as it can be and crafting the best possible script.
