Jamie Irvine:<\/strong><\/h4>\n\n\n\nYeah. That\u2019s what I see as well. And I think to a large degree, I think that those intervals and that iteration of technology… in many ways, it\u2019s a good thing, because it gives us an opportunity to adapt. It gives us an opportunity to test different ideas and see which one works the best! With all this change, it presents both challenges and opportunities. And really, I think that\u2019s what you\u2019ve capitalized on with this new technology.<\/p>\n\n\n\n
[Interval]<\/em><\/p>\n\n\n\nRoadwarrior saw an opportunity. So, can you describe for us the product that you\u2019ve developed and really what, the Genesis of that product was?<\/p>\n\n\n\n
Dave Jerman:<\/strong><\/h4>\n\n\n\nAbsolutely. Roadwarrior prides itself on being an innovating company as part of the DCL technology group. So, we were the first in the aftermarket to offer catalysts and DPFs in the marketplace as an alternative for our customers. And now with electrification, like we talked about, we want to dip our toe in the water, for lack of a better word.<\/p>\n\n\n\n
So, we looked at opportunities since we were really focused on serving the heavy-duty trucking industry. We saw the electric APUs as an electrification movement that we can assist in because the electric APUs are designed to power the sleeper cabs without having to idle the main engine. However, the traditional lead-acid or AGM batteries that are provided with the electric APU don\u2019t have enough capacity to run the power needs of the HVAC system and the accessories all night.<\/p>\n\n\n\n
So really the system was not being utilized, because it was paired with the wrong battery. So we were, to the best of my knowledge, not only the first, but the only manufacturer to specifically design and engineer lithium iron battery. Our LightningVolt is a drop-in plug-and-play replacement for electric APU storage batteries.<\/p>\n\n\n\n
Jamie Irvine:<\/strong><\/h4>\n\n\n\nOkay. So, in those early model electric APUs, they were just using like a group 31 starting battery? Kind of the same one you would find in a bank of four on the class eight truck? Or what was the battery?<\/p>\n\n\n\n
Dave Jerman:<\/strong><\/h4>\n\n\n\n[…] We\u2019re starting to see some options for lithium. But there\u2019s a lot of legacy electric APUs out there that are still today being installed with […] traditional lead-acid or deep-cycle AGM batteries, which is perfect for a starting battery, but not ideal for a storage battery.<\/p>\n\n\n\n
Jamie Irvine:<\/strong><\/h4>\n\n\n\nYeah. Well, I mean, I was just thinking about when I sold batteries […] draining down those batteries, those starting batteries down to nothing and then having to charge \u2018em back up that over time… that\u2019s what leads to those batteries just not being able to hold a charge and provide you the power that you want. So yeah, just a situation of like evolving technology and there\u2019s a leg in people moving forward with batteries. That\u2019s great that you took advantage of that. So, what\u2019s the big difference between lead-acid and AGM batteries and lithium?<\/p>\n\n\n\n
<\/figure>\n
Dave Jerman:<\/strong><\/h4>\n\n\n\nJust as you mentioned, the lead acids and AGMs don\u2019t like to be deeply discharged over and over. As you do that, you lose capacity and further to that, the system is controlled by voltage. So, you know, a fresh battery when it\u2019s fully charged is above 13 volts, about 13.2, and as a lead-acid or AGM battery starts to lose its state of charge, it kind of goes down on a diagonal. And when it\u2019s about 50% capacity voltages are between say 12.6 to 12.4 volts and around there, and the system, to protect itself, will start to load shed and maybe auto-start the truck. So really, you\u2019ve only used about half of that 100-amp capacity and already you\u2019re starting your truck. So, it kind of defeated the purpose. <\/p>\n\n\n\n
The nice thing about lithium technology, it stays above 13.2 volts until it\u2019s almost 95% discharged. So now you\u2019re getting twice the usable power\u2014you\u2019re using almost that total 100-amp hours. So that\u2019s the big difference. You\u2019re essentially getting twice the power and it\u2019ll last much longer, like up to 10 times longer than your lead-acid because it can handle that deep-cycle discharge without hurting.<\/p>\n\n\n\n
Jamie Irvine:<\/strong><\/h4>\n\n\n\nWhen are you recharging these batteries? Is it when the truck’s started and then as they\u2019re driving down the highway, some of that charge from the alternator is being sent back to those batteries, or how does that work?<\/p>\n<\/div><\/div>\n\n\n\n
Dave Jerman:<\/strong><\/h4>\n\n\n\nYeah. Correctly, the system\u2019s designed that they\u2019re equipped sometimes with an isolator, or without an isolator, to kind of combine both battery banks and separate them. So, what we did is we specifically designed and engineered the battery management system to work with the existing electronics. So, it\u2019ll work with the factory installed alternator. It has enough power to supply the lithiums and the AGMs that work in conjunction together with them seamlessly. And that battery management system… Like I said, what we\u2019ve done differently, is when you take an off-the-shelf lithium, the battery management system won\u2019t be calibrated to work as a plug-and-play and drop-in. So, this is what Roadwarrior\u2019s done differently. We\u2019ve designed it as a drop-in plug-and-play install to work with the existing electronics and alternator system.<\/p>\n\n\n\n
Jamie Irvine:<\/strong><\/h4>\n\n\n\nYou know, being the first to market with something is always bold. What has made this kind of a hard problem for others to solve? Like why is that challenging and how were you able to solve those challenges?<\/p>\n\n\n\n
Dave Jerman:<\/strong><\/h4>\n\n\n\nI think in taking the time to test it. So, it\u2019s easy to think about something but we have to test and give proof of concept. So, we\u2019ve been working on this for a number of years. We approached some customers of fleets that have been great and allowed us to access their trucks, to test them.<\/p>\n\n\n\n
It\u2019s that kind of first, second, third, fourth generation to make that investment and then kind of tweak those settings and engineering that battery management system to work seamlessly. Because the electronics of the truck is very sophisticated today. So, you can\u2019t just drop in anything, and assume it\u2019s gonna work. You\u2019re gonna have interruptions and things happening or not communicating properly or charging properly… things of that nature. So, we\u2019ve kind of had a learning curve. We\u2019ve done a lot of in-lab testing and then real-world testing, working with a variety of fleets that we were very happy to cooperate with and we appreciated their support!<\/p>\n\n\n\n
Jamie Irvine:<\/strong><\/h4>\n\n\n\nYeah. It\u2019s so essential to get that real world testing done so that you can really see what it\u2019s gonna do. And that gives you the opportunity to talk about economic impact! So, when someone is using like a lead-acid or an AGM battery and they\u2019re running those batteries down and those batteries die… I mean obviously the replacement cost of those batteries is going to be what it is. And it can be a few hundred dollars up until over a thousand dollars. When you put these ones in, I\u2019m assuming maybe the purchase price might be a little higher? But on the back end, the person\u2019s gonna save a lot of money because they\u2019re not gonna have to replace the batteries as often. Is that the primary source of savings when you look at a little bit longer timeline?<\/p>\n\n\n\n
<\/figure>\n
Dave Jerman:<\/strong><\/h4>\n\n\n\nActually, it\u2019s twofold. It\u2019s the replacement… So yeah, I\u2019d say the traditional lead-acids and AGMs have to be replaced every 1\u20132 years. The lithiums will last many times longer than that, so the replacement intervals will be lower. But further to that, it\u2019s because you\u2019re getting twice the usable power. You\u2019re gonna get a return on investment on fuel savings alone!<\/p>\n\n\n\n
So, we had one fleet who says, \u2018oh, we have an electric APU. My driver doesn\u2019t idle.\u2019 We said, we\u2019re gonna put a logging system on there. And we\u2019ll let him know he has lithiums and see what happens.\u2019 And when we talked to the driver, he had what we call battery anxiety. He knew that he didn\u2019t have enough power to run them. So, what he would do\u2014he’d be running the truck for 4\u20136 hours every day, because he knew he wouldn\u2019t make it. And then he’d just turn on his electric APU maybe at night to run his heating and cooling.<\/p>\n\n\n\n
So, he was defeating the purpose. We told him you got the lithiums now, run them! And then what we found was they saved about 800 hours of idling in just about three to four months. So that\u2019s right there at today\u2019s fuel prices, that\u2019s over $3,000. So, you\u2019ll get a return on investment in this scenario in less than three months, which is crazy. It becomes a no brainer.<\/p>\n<\/div><\/div>\n\n\n\n
Jamie Irvine:<\/strong><\/h4>\n\n\n\nOh, that\u2019s so great. Because many times, you know, when I was selling parts, I\u2019m trying to convince fleets like, you know, spend three times as much on spring brakes or on brake material, spend three times as much upfront and over four years you\u2019ll get the money back.<\/p>\n\n\n\n
And it\u2019s almost like it was such a long interval that it was hard. And it\u2019s not that the numbers weren\u2019t real, but it\u2019s kind of hard to like… you know… you don\u2019t get that immediate payoff. But with this, that immediate payoff, that\u2019s fantastic. And then in the long term, they get the additional savings of not having to replace those batteries as often, which also it\u2019s not just the replacement cost, as we all know, they also have to pay somebody to switch \u2018em out.<\/p>\n\n\n\n
Dave Jerman:<\/strong><\/h4>\n\n\n\nOh, 100%. So, like I said, not only a replacement, but it\u2019s the fuel savings. And then it\u2019s what we\u2019re trying to do. It\u2019s environmental, reducing greenhouse gases not to mention the wear and tear on the engine, the amount of hours that you\u2019re running, the aftertreatment system doesn\u2019t like idling. […] The ROI comes from a lot of places. Not just one thing where you\u2019re seeing just a replacement cost. You\u2019re getting benefits in many different areas. And you know, we didn\u2019t time the price of fuel to be right. So, us entering the market when the fuel prices are skyrocketing, […] the ROI was a lot easier to justify or the payback was a lot shorter than you would typically see when fuel prices were lower.<\/p>\n\n\n\n
Jamie Irvine:<\/strong><\/h4>\n\n\n\nRight. Well, you have to be good to be lucky and lucky to be good and you guys are good and lucky. So that\u2019s awesome. You know, your expertise when you were on the show before we were always talking about diesel emission systems and engines. Let\u2019s talk a little bit about that because I think that there is some misunderstanding. Or maybe some leftover bad, not bad habits, leftover old habits from some of the older technology with engines. Like as far as what I\u2019ve been learning lately, these new engines, they don\u2019t like to idle. And certainly, the diesel emission system doesn\u2019t like idling.<\/p>\n\n\n\n
So, let\u2019s talk a little bit about that because that, that\u2019s also a significant part of all of this. If we could reduce idling, it does impact the engine and the diesel emission system. And as we all know, that\u2019s a pretty costly system to maintain and repair.<\/p>\n\n\n\n
Dave Jerman:<\/strong><\/h4>\n\n\n\nFor sure. That\u2019s why it was a perfect fit. Not only does it bode well for the savings, but the wear and tear on the engine. And because we saw the aftertreatment system\u2014DPFs and SCRs and the aftertreatment system as a whole doesn\u2019t like idling. When you\u2019re idling, you\u2019re just loading and straining the system and reducing the shelf life and increasing the maintenance intervals. So that\u2019s as if now you\u2019re damaging it altogether.<\/p>\n\n\n\n
So, even from a warranty perspective…For OEMs, anything over 20% idle could be considered excessive idling, and they could actually even deny your warranty. I\u2019ve been at a few seminars where some manufacturers said, if we go into your ECM and see you\u2019ve been idling over 20%, this gives them grounds for denial due to excessive idling. So, these are the types of things that, you know, truck owners and fleet operators have to be aware of. That you know, idling is not only bad for the environment. It\u2019s bad for your pocketbook and the overall […] maintenance costs and costs per mile for keeping that truck on the road.<\/p>\n\n\n\n
Jamie Irvine:<\/strong><\/h4>\n\n\n\nRight. And if by using this new battery system with your EAPU, and then if you could even eliminate like one DPF cleaning a year or something like that, like that\u2019s also money in the bank. So, like, no matter how you look at it, this is good, good, good, good.<\/p>\n\n\n\n
Dave Jerman:<\/strong><\/h4>\n\n\n\nOh, that\u2019s what I mean. It\u2019d be so hard to put a number on the maintenance cost or the wear-and-tear side of things that that\u2019d be very hard to quantify! So those are definitely benefits that you don\u2019t have to explain to any mechanic or service manager that idling is bad for your engine. So anytime you can reduce idling, people\u2019s ears will perk up. If I could reduce idling, I\u2019m saving money, I\u2019m saving fuel. It\u2019s better for the environment and it\u2019s gonna reduce my maintenance interval. So, that becomes a much bigger conversation. […] <\/p>\n\n\n\n
And not to mention the batteries are half the weight as well\u2014they\u2019re lighter. So, there\u2019s a lot of added benefits that you get. So even reducing weight on a truck! People always wanna put weight towards carrying freight, not towards the vehicle, so that\u2019s another smaller benefit as well. They\u2019re half the weight of the lead-acids!<\/p>\n\n\n\n
Jamie Irvine:<\/strong><\/h4>\n\n\n\nSo, you can literally be a superhero by buying these batteries because you can save the environment, you can lower idling costs and wear-and-tear. You can reduce the fuel consumption. You can decrease the weight on the truck. And then on top of that, you can get better performance out of your batteries for the driver. So, your driver satisfaction is gonna go up! So be a superhero, head over to roadwarrior-inc.com and check out their new products.
