The average Chariot e-bus electricity consumption: 0,98 kWh/km.

Figure is achieved carrying on passengers along Line 11 in Sofia covering daily peak hours.

The consumption is registered having AC permanently ON.

In the peak-off hours having few passenger the Chariot e-bus consumption could go as down as 0,6 kWh/km.with AC permanently ON

This turns the e-bus into the most economical efficient urban transportation vehicle worldwide.

From the European study below it could be seen that the battery e-bus alternatives are expected to have a consumption of 1,8 kWh/km.

According to other studies the figures obtained from operators of battery powered buses range from 1,5 to 3,5 kWh/km. Ultra Capacitor buses operate in the range of 1,0 to 1,5 kWh/km (Source: energize-march-14-p-69-74).

Thus Chariot e-bus consumption per km is up to 3 times lower than the most advanced known e-buses.

Opportunity e-buses are electric buses that aim to minimize the weight of the battery by recharging en route at passenger stopping points. They are promising in terms of projected costs and require a network of recharging points”.

Overnight e-buses are electric buses that carry the weight of battery required to drive the entire route without recharging. They are flexible in their route, but over the next 10 years are not expected to meet average daily range requirements nor carry a sufficient number of passengers due to the weight of the batteries”.
