Proterra has selected Toshiba as the battery supplier for its next-generation electric bus.
Toshiba’s SCiB batteries feature a lithium titanate oxide chemistry, making them resistant to thermal runaway and lithium metal plating. The 20 Ah prismatic cells have nominal voltage of 2.3 V, gravimetric energy density of 90 Wh/kg and volumetric density of 177 Wh/L. The cells can charge from 0% to 80% state of charge in 6 minutes. SCiB cells are capable of 10,000 or more charge-discharge cycles, depending on operating conditions.
“With a rapid recharge capability and outstanding life performance, Toshiba’s SCiB battery is ideally suited for zero-emission public transit,” said Toshiba VP Greg Mack. “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.”
“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,” said Proterra CEO Ryan Popple. “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.”
