Chariot Ultra Capacitor e-bus
Copyright © 2018 by Chariot Motors
1 Desire for zero emissions urban transport vehicles
The electric buses are going to become the most preferred rolling stock to be procured by the public operators in Europe within the next couple of years
All across Europe the capitals and big cities are introducing policies for promotion and purchase of electric buses.
Several European countries already announced that they will completely ban the diesel buses on national level and only and electric buses are going to be purchased.
From the perspective of Total Cost of Ownership the electric buses are the most economical vehicles for public transportation.
2 About the company
Chariot Motors together with Aowei Technology have developed the first ever ultracapacitors electric bus (Chariot e-bus) to be used for commercial operation in Europe.
Chariot e-bus is purely ultracapacitor (UC) based city e-bus that deploys the latest electric drive and world’s most advanced ultracapacitor technology by Aowei. Chariot e-bus is assembled at a special high quality production line at one of the world’s biggest bus factories, Higer bus factory, with more than 17,000 hybrid & electric buses produced per year.
Chariot e-bus is a silent, low-cost vehicle with zero-emissions, which complies with the European homologation certifications, the strict market requirements in EU, including the ECE R100 standard for energy storage devices.

10 Key Chariot UC е-bus features
• capable of travelling about 25 km – 30 km on a single charge performed for 2 - 5 minutes at the terminal, based on the 40 kWh UC, 470 A charging current; • charging at terminal(s) only and not on passengers stops; • economical means of transportation with proved average consumption of about 1.1 kWh/km including AC; • low maintenance cost due to the lack of expensive-to- maintain combustion engine vehicles systems; • does not require overhead power line, thus avoiding infrastructure and maintenance costs; • not influenced by outside temperatures and capable of operating with ease in various weather conditions; • passengers load of a regular trolleybus / diesel bus.
11 Technological and operational advantages of ultracapacitors compared to the batteries
• Aowei’s ultracapacitors accumulated more than 11 years / 12 million km of experience and used in electric buses since 2006 being the most matured energy technology used in for electric buses; • average energy recuperation rate of the ultracapacitor is 32.2%, reaching up to 39%; • ultracapacitor is mounted in a safety container preventing risks in case of accident; • Operational temperatures form -30°C to +60°C; • The UC contains no harmful or toxic substances leading to no pollution of hazardous disposal at no extra disposal cost; • no energy storage replacement-related costs; • Charging factor is 10C • less powerful charging infrastructure compared to batteries;
12 Comparison between UC and fast charging batteries Ultracapacitor Fast charging batteries Performance • Excellent in broader temperature • More sensitive operation in range. About 20% better broader temperature range performing than fast recharge battery. Safety • Excellent with explosive proof • Good, but there is the tank. possibility of fire. Recuperation • As per Belicon institute study the • lower recuperation levels, thus average recuperation is 32.2% higher electricity consumption reaching up to 39%. Charging time • About 3 minutes as UC could • About 5 minutes Charging factor afford 10C • LTO battery could afford 4C charging, LpCO could afford 3C charging Lifetime • Manufacturing warranty of 8 years • Replacement after 5-7 years of Warranty that could be extended to 10 years operation. • Manufacturing warranty is 5 years. Disposal • No toxic /hazardous substances • More demanding disposal costs 13 Results from an independent validation by BELICON Chariot e-bus performance
