Modular battery pack design

  • From all of us at Scout Motors, welcome to the Scout Community! We created this community to provide Scout vehicle owners, enthusiasts, and curiosity seekers with a place to engage in discussion, suggestions, stories, and connections. Supportive communities are sometimes hard to find, but we're determined to turn this into one.

    Additionally, Scout Motors wants to hear your feedback and speak directly to the rabid community of owners as unique as America. We'll use the Scout Community to deliver news and information on events and launch updates directly to the group. Although the start of production is anticipated in 2026, many new developments and milestones will occur in the interim. We plan to share them with you on this site and look for your feedback and suggestions.

    How will the Scout Community be run? Think of it this way: this place is your favorite local hangout. We want you to enjoy the atmosphere, talk to people who share similar interests, request and receive advice, and generally have an enjoyable time. The Scout Community should be a highlight of your day. We want you to tell stories, share photos, spread your knowledge, and tell us how Scout can deliver great products and experiences. Along the way, Scout Motors will share our journey to production with you.

    Scout is all about respect. We respect our heritage. We respect the land and outdoors. We respect each other. Every person should feel safe, included, and welcomed in the Scout Community. Being kind and courteous to the other forum members is non-negotiable. Friendly debates are welcomed and often produce great outcomes, but we don't want things to get too rowdy. Please take a moment to consider what you post, especially if you think it may insult others. We'll do our best to encourage friendly discourse and to keep the discussions flowing.

    So, welcome to the Scout Community! We encourage you to check back regularly as we plan to engage our members, share teasers, and participate in discussions. The world needs Scouts™. Let's get going.


    We are Scout Motors.

Design the battery system for maintainability/upgradeability.

Battery modules (groups of cells) should be individually replaceable and the entire battery pack should be designed to minimize the effort necessary to replace it.

This would ensure these vehicles will remain viable into their 2nd and beyond lives, and be able to leverage inevitable improvements in battery tech over time.

I see where the OP is going with this and normally I'd be all for it. Bring back replacable phone batteries!!

But for a lot of what's been said already, the practicality starts to go out the door. I'd imagine the battery pack and compartment needs to be very precise to handle all the rough terrain these vehicles will handle. So making it more general may in fact start to have a safety risk involved.

I'd argue that the effort and research money should go into the actual recycling process than making it user swappable.
Its not that hard - Jaguar did it, but there isn't a recycling model that works, and the I-Pace isn't old enough to need it.

However, they did have a recall that required some batteries to be replaced (these were Panasonic batteries I believe...don't quote me though), so that may have made a difference for the automaker.

User replaceable batteries aren't practical at the moment - they're way too heavy, and you can't get them at AutoZone.

There are several auto battery recycling startups - automakers like Toyota, GM, and Ford are investing in this tech as well as private venture capital. If Scout was to develop the standards and engineering practices for designing and servicing modular batteries, they could license that tech to many providers as an additional source of revenue, and recover some of that engineering cost.
