CATL Freevoy: 2 Batteries, 1 EV! (IAA 225 Tech Interview)

*MANDATORY DISCLAIMER*: Transport Evolved was invited by CATL to attend the reveal of the Shenxing Pro battery at IAA Mobility 2025. CATL reimbursed our travel, meals, and accommodation to enable us to bring you this first-person report. YouTube requires this video be marked as "sponsored" due to our reimbursement arrangement. However, while a representative from CATL was allowed to view the video prior to publishing to verify quoted figures, Transport Evolved retained full editorial and final production control. Following our coverage of CATL’s IAA 2025 announcement of the Shenxing Pro for Europe, we had a chance to chat with other CATL engineers on the company’s stand before exploring the rest of IAA. Today, we’re diving into a dual-battery chemistry system designed to give automakers—and their customers—the freedom to mix and match battery chemistries in a single EV, reducing overall cost without compromising performance, capabilities, or lifespan. While CATL isn’t the only company working on this tech, it’s the first time we’ve been able to see one up close—so of course, we had to ask plenty of questions. *⏱️ Chapter Breakdown:* 00:00 - Introduction 00:45 - What is the Freevoy Dual Power Battery/ 01:36 - Different Chemistries... how does that work? 02:12 - Demonstrating the chemistry choices 02:47 - NCM use in Freevoy 03:20 - Which work best together? 06:05 - Use in static products? 06:50 - How to engineer different chemistries together? 08:26 - After sales and service implications? 09:50 - Thanks, and Goodbye! ---- *👥 Today’s Sponsors* 🌱 Electric Vehicle Association - https://www.myeva.org ⚡ EnergySage - https://www.kqzyfj.com/click-101290941-16952262 — ✊ Get Involved 🗳️ https://indivisible.org/town-hall-resources ❤️ Support the Show 📰 https://www.transportevolved.com 🔥 https://www.patreon.com/transportevolved ☕ https://ko-fi.com/transportevolved 📺 https://www.youtube.com/transportevolved 👕 https://www.redbubble.com/people/TransportEVd/ 🛍️ https://amzn.to/40xOyjm ₿ 1QRZRGCCXUKPDZ2DZ9KX9JYJXMZDYHYGFZ0MN4WH *💬 Join the Conversation* 🐘 https://mastodon.transportevolved.com/@show 💬 https://discord.gg/9WAjfQn 🌀 https://bsky.app/profile/transportevolved.bsky.social 🔁 Subscribe to our 2nd channel - https://www.youtube.com/transportevolvedtake2 --- *🎙️ Credits:* Host: Nikki Gordon-Bloomfield Guest: "Engineer Ranxing" - CATL Camera, Edit, Color: Vi Horton Art & Animation: Erin Carlie Producer: Nikki Gordon-Bloomfield Music: via Artlist.io
