UCR series Ultracapacitor (UC)
Benefits and motivation of bus
electrification
- Less carbon emission
- Energy saving (regenerative braking)
- More reliable (operational reliability& warrant)
- Low average expense each lifecycle
- Having Government policy support
Application example: UC electric bus
Why ultracapacitor
- Long operation lifetime - UC cell has 50000 - 100000 cycles of operation lifetime
- No limitation for the daily mileage - UC is charged at the end bus stop during the bus drivers’ break
- Better heat management - UC cell has lower chance of overcharge and over discharge
- Safer - UC does not burn/explode even if the faults happen
- Clean - UC contains no harmful or toxic substances
- Lighter battery - Almost 1/3 weight as normal battery
- No need to balance UC overnight - this can be accomplished by a separate Blockheater
Market advantage
Comparing traditional EDLC with ultracapacitor
Application Example
Bus in Sofia 2014
- Operated and maintained by the StolichenElektrotransport; 20 kWh UC –1st Generation;
- Line № 11 (trolleybus line) -> flat profile, length of 11.2 km, crossing;
- DC/DC charging stations at terminals only, using trolleybus power supply;
- Average energy consumption, recorded by BELICON: 0.95 kWh/km (no auxiliary consummators);
- 1.60 kWh/km with 100% occupancy and A/C on;
- Recuperation rate: 32.2 %, highest 39%;
- Operating temperature range: -15℃ to 40℃;
- Siemenselectric motors, 2x67 kW;
-
