No. 1641:

Many new electric buses have arrived in Norway, but as far as I know, only Yutong has the batteries attached to the bus body!

Where is the battery on a Yutong bus?
Thorough study of the vehicle's actual operating conditions, battery units are installed at the top, back and bottom of the bus body.
Why are most other electric buses, not least regular buses that I know best, placed on the roof?
This is really against all common sense. And here it is the Yutong buses that have not done this.
Strange that other buses are allowed to continue like this?

I drive a bus in Vestby now, and there we will have BYD buses with batteries on the roof.
But in Drøbak they will have Yutong buses with batteries on the floor.
These buses should have been standard buses in my opinion.
They are attached to the bus body itself.
Fantastic. Magnificent!

At the other end we have the Solarius buses that Unibuss received in April 2023 which have 4 packs of batteries on the roof in the middle of the bus.
Drive axle at the back where they have 2 packs on the roof.
Is it that bad that it is possible to place batteries?
See picture for how the batteries are placed.

In the tender competition, is it only money – not quality and safety that counts?

The buses will be far safer and in a difficult situation. Will the driver have a much greater chance of saving himself, the passenger and the bus with Una maneuver with a bus that has the batteries attached to the frame. A bus with the batteries on the roof. Is in a completely different way difficult to get back in.
This is what I learned on the slippery driving course where I tested buses with the batteries both on the roof and on the floor.

AI overview
Yes, there are electric cars with batteries placed in the floor. This is a common solution to lower the center of gravity and free up space in the bus. The batteries can be placed in a module in the floor, or in a chassis where the batteries are placed low.

Advantages:
Lower center of gravity: Provides better stability and driving characteristics, especially in corners.
More space: Frees up space in the bus that can be used for passengers or luggage.
Safety:
The batteries are placed in a robust chassis and can be designed to withstand fire and impact.
Efficient use of space:
The batteries can be stacked in modules to maximize capacity and range.

I was on a slippery driving course and really got to try buses with the battery differently placed.
The batteries on the roof in a difficult situation were much more difficult to pull back in.
Even at a lower speed than the Yutong, which was a much better bus.
Then it is completely incomprehensible that this with the battery is not in the tender competition that they should be located in and around the framework.
So, as low as possible in the bus. And closest to the drive axles is also a clear advantage.
Here in Oslo, there are buses that spin on dry asphalt.
What is the reason?
One of the reasons, if it is also probably the main reason?
Is where the battery packs are located!
