"Nyobolt, the developer of ultra-fast charging niobium-based battery technology revealed the first running Nyobolt EV prototype.
Initial in-vehicle testing this month using 350kW (800V) DC fast chargers has confirmed that Nyobolt EV’s 50Ah 35kWh battery can be charged from 10% to 80% in four minutes 37 seconds—with a full charge enabling the prototype to achieve a range of 155 WLTP miles. That is twice the speed of most of the fastest charging vehicles today.
Nyobolt’s technology also solves the levels of degradation that typically come with supercharging lithium-ion batteries. Nyobolt’s 24.5Ah cells have already successfully completed more than 4,000 full DoD (Depth of Discharge) fast charge cycles, equating to more than 600,000 miles if used in the Nyobolt EV pack, while still retaining more than 80% battery capacity. This is many multiples higher than the warranties of much larger EV batteries on the road today.
Independent OEM testing confirmed Nyobolt 2.6Ah cells can achieve more than 4,400 cycles with a 12C charge and 1C discharge at 23°C. Crucially, the cell internal resistance rises by only 50% after 4,400 five-minute charge cycles. This is lower than the industry accepted end of life values for EV cells, which is typically twice the initial value."
