Microvast Lithium Titanate Battery Maintains 97% of Initial Capacity After 3,000 Quick Charges and 2 Year in Operation in Electric Bus (w/videos)

Buses with Microvast Lithium titanate battery

Microvast is a relatively unknown company that’s been developing and producing some interesting lithium-ion batteries with lithium titanate chemistry called LpTO (similar to Altairnano).

These batteries have been used for some time now in some electric buses in the Chinese city of Chongqing.

First fully electric buses to use Microvast technology started operation on two lines in Chongqing in April 2011. Today, there is about 31 EV buses and many more plug-in hybrids – all with fast charge in 10-minutes capabilities (like US-based Proterra).

Total mileage for all 31 buses is 710,000 km, but the first six accumulated almost 60,000 km on the odometer and over 3,000 quick charge cycles. Microvast is saying that battery capacity of these buses faded by only 3% and all are working excellent, but doesn’t that seem too far-fetched to be true?

Chongqing buses are using 556 V / 110 Ah and 556 V / 140 Ah battery packs.  Starting last year spring these buses began charging on the new, huge 3.2 MW charging station with 400 kW DC fast chargers.

    Its nice to dream, but BYD’s 325 kwh buses (compared to the 62 and 78 kwh systems from MicroVast) require no additional costly infrastructure…. You’d think a battery company would come up with turnkey systems that relied more on Batteries…

    That said, it will first be necessary to verify their claims. Chinese companies (the American Management notwithstanding) tend to overclaim and underdeliver.

    Ask anyone who has bought a chinese drill press and have to hammer the motor everytime you run the thing to make the stuck starter switch work… Or for permanent split smaller models like the ones Sears sells, the things die after a month due to the capacitor failing).

      Bill, go and try to buy a made by US company advanced Li-ion battery nowadays and you will find none. It is a painful realization but it is true that Asia companies are leading the charge of battery innovation technology. I actually work for Microvast and feel free to go and examine the operational data and battery status in China at your convenience.
