Quantron launches 12-m battery-electric bus; fuel-cell variant to follow
Quantron's new Cizaris low-floor city buses will offer two- and three-door variants along with nine interior layout options.
New European bus manufacturer Quantron has launched its first
product, the Cizaris, a 12-meter (39.4-ft) long electrically powered
bus. The German company was launched in 2019 as a spinoff
from Haller, a company that has specialized in the distribution,
repair and service of commercial vehicles, buses and RVs.
First to market later this year will be the Cizaris 12 EV featuring
battery-electric drive. This bus will be followed by a hydrogen
fuel-cell-powered variant, the Cizaris 12 H in 2023. Both will be
low-floor city buses. Quantron will offer two- and three-door
variants and customers will have a choice of nine interior layouts.
Quantron is working in partnership with Chinese manufacturer
EV Dynamics to produce the Cizaris. The design features
temperature-controlled lithium iron phosphate (LFP) roofmounted
battery packs produced by CATL, with up to six in
the front section and up to six in the rear section, depending
on customer requirements. This will provide 242 kW/h, 281
kW/h, 363 kW/h or 424 kW/h of battery capacity.
Quantron claims that with a direct current (DC) power
source of between 65 and 150 kW, the batteries could be recharged
in two to five hours. Measured on the medium-heavy
eSORT 2 cycle, this should provide a range of between 220 to
370 km (137 to 230 miles), with a charging stroke (depth of
discharge, or DoD) of 10%. Range data is not yet available for
the hydrogen fuel cell Cizaris 12 H variant. The CCS combo
charging socket can be mounted on the right, left or rear of
the vehicle, as required.
The bus is powered by a Dana TM4 vehicle-mounted permanent
synchronous motor (PSM), mounted centrally.

Quantron quotes a power output of 145 kW/245 kW nominal/
maximum (194 hp/329 hp) and maximum torque output of
1,055 Nm/3,329 Nm (778 lb ft/2,455 lb ft). Quantron promises
greater power from the hydrogen fuel cell powertrain. The
company claims that the centrally mounted motor does not
add to unsprung mass like an electric portal axle and is less
exposed to vibration, contributing to a longer service life than
such axle-mounted motors.
The CCS combo charging socket can be mounted on the right, left or rear
of the vehicle.
