AVM 27' electric shuttles fully charge 50-60-kWh batteries in 10 minutes:
One possible issue with 350-kW chargers is the risk of fire at the charging point. Clearly this technology is improving steadily, but I think there will be some growing pains as well as issues related to wear that occurs with connectors used so frequently at such high power levels. I suspect roof-mounted high-current contacts will tend to be more successful in many applications (except in the case of snow and ice). We'll have to see how things play out.
I've only ever heard of chemistries which can withstand 10,000 full cycles out there, which could yield a few years of cycling in such operations, but the article claims that the LTO chemistry used here can withstand 20,000:InsideEVs said:The AVM EV27 is mid-size 27-foot long shuttle for loop-based routes supporting corporate and school campuses, hotels and rental car facilities, airports, and affording “first/last mile” solutions to private communities.
The vehicle stands out due to its 350 kW ultra-fast charging through CCS Combo in less than 10 minutes.
In fact, the following cycle-life curve at the AVM website indicates WAY more than 20,000 cycles with less than 10% degradation:AVM as quoted by InsideEVs said:“AVM’s exclusive joint venture is powered by Yinlong Energy, one of the world’s leading energy manufacturers and innovators. AVM shuttles are powered by Yinlong’s proprietary lithium–titanate battery (LTO) technology. An extremely safe and long-lasting lithium-based technology, LTO cells can endure more than 20,000 cycles, ensuring the batteries’ lifespan exceeds that of the vehicle. This robust and proven technology takes full advantage of AVM’s 350 kW CCS 2.0 high-powered charger, enabling the EV27’s rapid charge time.
