Proterra selected Toshiba as the Lithium Titanate Oxide (LTO) battery supplier for its electric buses.

Of course, in regards to SCiB batteries, the ability to quick charge in 10 minutes and last for 10,000 cycles is the selling point. These are two parameters – quick charging and long life, that are especially important to Proterra:

“Proterra buses feature a fast charge system that takes less than 10 minutes to charge during regularly scheduled route stops, making the buses well-suited to transit applications.”

Previously, Proterra was using LTO batteries from Altair Nanotechnologies.

Greg Mack, Vice President of Toshiba International Corporation’s (TIC) Power Electronics Division stated:

“With a rapid recharge capability and outstanding life performance, Toshiba’s SCiB battery is ideally suited for zero-emission public transit. Toshiba has decades of experience in transportation and we see the SCiB battery as key to expanding environmentally-friendly modes of transportation with optimum power performance in North America.”

Proterra Inc. CEO, Ryan Popple remarked:

“Because safety and performance are paramount to Proterra, we are very deliberate in each part we select for our buses, putting vendors through a rigorous qualification process. Battery quality is critical to the performance of Electric Vehicles; partnering with a world-class team like Toshiba and utilizing SCiB technology will enable Proterra to offer its customers the highest-performance, safest, and most reliable urban transit vehicles.”

About SCiB:

“The SCiB is part of a wide range of solutions designed to enable smarter communities. Leveraging expertise cultivated since the company’s foundation, Toshiba is committed to being a global leader in smart community solutions that enrich the quality of life for people throughout the world. The Toshiba Group has already participated in more than 30 smart community demonstration projects highlighting battery storage and cloud-based solutions for social infrastructure that satisfy the differing needs in developing and developed countries. With a wide range of experience and know-how acquired from the stable operation of social infrastructure over many years, Toshiba is confident in its ability to present more effective and more sophisticated solutions based on precise simulations and highly accurate predictions.”

“Toshiba’s SCiB batteries have excellent thermal performance, enabling their high-rate charging capability. The lithium-titanate chemistry contained in SCiB makes the batteries highly resistant to thermal runaway and lithium metal plating, providing exceptional battery safety characteristics.”

“SCiB products also offer minimal capacity degradation and are capable of 10,000 or more charge-discharge cycles, depending on operating conditions. This operational life often exceeds that of the applications in which they are used, eliminating the need for battery replacement and reducing the environmental impact of waste batteries.”

10 minutes is impossibly fast, but wait, no it’s not. I think this reflects the fact that you could put a 75 mile bus on a 25 mile route and blast it with 10 minutes of power at the end.

The blast would hit the batteries at the sweet spot of the charge cycle and get all the needed miles in only 10 minutes. This 30-60% sweet spot is also exactly where you need to keep the battery to make it last 30 flipping years.

I think it’s possible that one way of getting lithium battery advancements is just getting them cheap and light enough to not even care about the upper and lower 33% of the charge cycle–not even having to use it, ever.

City buses appear to be one market where it’s already possible to do this!
