ORIGINAL EQUIPMENT
" The centrally mounted motor
does not add to unsprung mass like
an electric portal axle and is less
exposed to vibration. "
Adapted e-bus platform
The Cizaris is based on an electric bus platform that is already
widely used but differs in that both the drivetrain and the rear
sections are new designs. The roof also is completely new and
has been designed to accommodate either the battery packs or
hydrogen tanks for the fuel cell variant. Two-door models will be
offered with four seating configurations, while three-door variants
will have a choice of five. This will provide seating for between
24 and 35 passengers, with total capacity of between 81
and 95 passengers, depending on the battery package adopted.
A 33-kW Valeo heat pump and air-conditioning unit controls
the temperature on board, while the heating capacity
can be stepped up to 50 kW using a Positive Temperature
Coefficient (PTC) system to regulate heat output, while effectively
reducing energy consumption. Options include anti-viral
filtration and a closed driver's cab. A perforated aluminum
ceiling provides indirect side lighting with additional LED
lights mounted in it. The LED lighting colors can be changed.
Driver controls include a large monitor for the rearview
camera and other functions. Regenerative braking is controlled
by a lever to the right of the steering wheel and offers
three stages of retardation. A digital instrument pack is standard,
provided by Actia. High-resolution camera mirror monitors
are mounted in front of the A-pillars. The vehicle can be
specified with a separate nose observation camera, paired
with a large monitor above the cockpit.
Temperature and gas sensors in the rear compartment, battery
modules and other high-voltage components provide fire
protection. The front axle is equipped with a central lubrication
system to optimize service life.
Based on an existing electric bus platform, the Cizaris features a new
drivetrain, rear sections and a roof designed to accommodate either the
battery packs or hydrogen tanks for the fuel-cell variant.
Quantron will offer a two-year warranty for the entire vehicle
with an eight-year/3,000 charge cycle/80% charge capacity
warranty, whichever comes first for the batteries. The company
can offer battery recycling options at the end of their life. An
FMS 4.0 interface will provide on-board connectivity. Quantron
is also investigating the use of its Capte or VinCity partner
telematics system to download bus data remotely.
