First customers order the Mercedes-Benz eCitaro bus, deliveries this year; solid-state batteries, fuel-cell range-extender coming

Green Car Congress

Lithium-ion batteries with a total capacity of up to about 243 kWh provide the power for the eCitaro. To this end, the city bus has a connection for a Combo 2 plug. In the case of a city bus, this is impacted significantly by climatic conditions and consequently by the need to cool and, above all, to heat the interior.
