2023-09 SUSTAINABLE BUS
A new issue of Sustainable Bus is out today. In this upcoming edition, we’ve curated a diverse and comprehensive range of topics that spotlight the latest developments in the world of sustainable mobility. From cutting-edge technological advancements to market insights and industry transformations, this issue promises to be a captivating exploration of the future of public transportation. What you could fine inside? Well, a market insight will offer you a detailed look at the European e-bus market, providing you with a comprehensive understanding of the mid-2023 results. The leading e-bus market in Europe is still UK: therefore, we focused our attention on that specific market with a report that sums up strategies, focus, goals of the most prominent industry players. A technology spotlight on the delicate topic of batteries, authored by Claudius Jehle, look at battery management and strategies to ensure the smooth and cost-effective operation of electric buses (with a focus on a case study from BVG). Among the pillars of our upcoming issue you’ll find a detailed journey around the European industrial bus&coach landscape. Goal? Providing our readers insights into the changing dynamics among key OEMs in the region. We’ll be then taking you behind the scenes at the Yutong factory in Zhengzhou, that we had the pleasure of visiting in June. Let’s then delve into Iveco Bus’s growing efforts in the zero-emission bus field. Finally, last but not least, a nearly-20-pages comparison between seven 12-meter battery-electric buses, gathered together in Bonn also this year by the German magazine Omnibusspiegel. You’ll find both established players and newcomers side by side: Ebusco 3.0, Hess lighTram 12m, Ikarus 120e, Iveco E-Way, Mercedes eCitaro with new batteries, Otokar e-Kent C, Quantron Cizaris 12 Ev.

IKARUS 120E<br />
CHINESE DEAL<br />
A welcome<br />
return. An<br />
historic Volvo<br />
bodybuilder,<br />
Ikarus launched<br />
an e-bus (soon<br />
to be updated)<br />
in collaboration<br />
with CRRC<br />
Today Ikarus<br />
works with<br />
a series of<br />
partners, in<br />
particular with<br />
Chinese CRRC:<br />
the bus is made<br />
in collaboration<br />
with the Asian<br />
giant, which<br />
manufactured<br />
both the<br />
chassis and the<br />
synchronous<br />
motor with<br />
permanent<br />
magnets<br />
capable of 240<br />
kW peak power.<br />
parts and high and low voltage electrical<br />
equipment, as well as 3,600 square meters<br />
for robotic welding. The engineering department<br />
is located on the same site. Onboard<br />
electrical system and software are<br />
made in Hungary.<br />
Hey, I’m back!<br />
An historic bodybuilder of the Volvo network,<br />
today Ikarus works with a series of<br />
partners, in particular with the Chinese<br />
CRRC: the Ikarus 120e is made in collaboration<br />
with the Asian giant (a partnership<br />
signed in 2018), which manufactured<br />
both the chassis and the synchronous<br />
motor with permanent magnets capable<br />
of 240 kW peak power (165 kW is the<br />
continuous supply) and 3,200 Nm of maximum<br />
torque (which has provided excellent<br />
results).<br />
The batteries are made by another Chinese<br />
giant: CATL group. The latter, in addition<br />
to being the largest manufacturer of<br />
EV car batteries in the world, has set its<br />
sights (and wallet) on Hungary with an investment<br />
of over 7.3 billion euros aimed<br />
at building a 100 GWh factory. Hungary,<br />
indeed, is establishing itself as a Europe-<br />
an hub for battery<br />
production by virtue<br />
of a flurry of Chinese<br />
investments that<br />
in recent years have<br />
reached 11 billion.<br />
To be clear, neither<br />
CATL nor BYD are<br />
isolated cases. Back<br />
to the bus, the available<br />
kWh are 315.<br />
The new range will<br />
allow for greater<br />
modularity, but on<br />
the 120e the options<br />
are just… one. The<br />
ten packs are distributed<br />
as follows:<br />
four at the rear, six<br />
on the roof. Given<br />
the manufacturer,<br />
the chemistry can<br />
only be LFP. The<br />
blind rear is very<br />
impactful, where the<br />
battery location prevents<br />
the presence<br />
of light above the five-seater. This should<br />
be reviewed. As well as the interiors: the<br />
choice of dark colors, however refined<br />
and elegant in their own way, is detrimental<br />
to the internal livability, which is already<br />
penalized by not having a window on<br />
the back. But the e-bus components are<br />
not only Chinese. The air conditioning<br />
is provided by a Valeo unit with 30 kW<br />
of cooling power and 20 kW of heating<br />
power. There is a diesel-powered supplementary<br />
heating system. The ZF RL82A<br />
rigid portal axle works at the front. At the<br />
rear there is the usual ZF AV133.<br />
Ikarus is back. The Hungarian manufacturer,<br />
with over a century of<br />
history, is returning to the European<br />
market by focusing strongly on electric<br />
technology. Currently, their portfolio<br />
includes the 120e model (tested in Bonn).<br />
This will soon be replaced by a new range,<br />
which is expected to be presented by<br />
the end of this year.<br />
The distribution of wheelbase and<br />
overhangs, 22-meter turning circle, and<br />
1,200 mm wide doors comply with practice.<br />
There is room on board for 85 passengers,<br />
33 of whom are seated on Ster seats<br />
(in addition to two folding seats). The<br />
empty weight is excellent, with 13 tons<br />
capable of outclassing much more famous<br />
models. The structure is in stainless steel<br />
and has been subjected to an anti-rust<br />
treatment (guaranteed for 16 years). Production<br />
takes place at the Székesfehérvár<br />
plant, 60 kilometers from the capital Budapest.<br />
There are 3,500 square meters<br />
dedicated to the assembly of mechanical<br />
