Positioning of batteries

[Steinar]

According to current regulations they state

"B8.14.2 Any fuel, compressed gasses, other energy storage media, HV systems and HV wiring must be contained within the primary structure of the frame and when located less than 350mm from the ground must be protected from side or rear impacts with a structure built to Rule B3.24 or B3.31 as applicable."

Can someone verify that this implies that securely attaching HV battery containers on the sides of the vehicle is not legal. And if so would it become legal if the framework was extended to the sides to surround them. I'm wondering here how strict the definition of "primary" part of the frame is regarding this issue.

All answers greatly appreciated.

Hi Steinar,

This question is better posted in the FSE Forum on formulastudentelectric.de

However you are right, it is legal to attach your batteries beside the driver as long as there is a Side Impact Structure AROUND your containers.

Watch the Video from DUT Racing of their 2011 concept or the MTZ/ATZ report of the Zwickau 2010 Car. They have a good package for Go-Kart seating positions with one big battery behind the driver. It is maybe a simpler solution, than having the boxes on the side of your car...

Hi Steinar and Blister,
I suppose that Steinar is refering to the Formula Hybrid rules, since there is no rule B8.14.2 in the FSE rules.
Therefore I am not quite sure, if Blister's answer is also correct for the Formula Hybrid rules.

Regards,

Tobias

The Formula Hybrid rule dealing with this issue is rule 4.7 "Energy Storage Container Mechanical Configuration". There is no B8.14.2 in FH either. Maybe it is an FSE rulebook for a separate event, like Silverstone?

Yes, you are right. I just found it in the FS UK Class 1A rules.
@Steinar: Maybe you should ask the organizers of Class 1A directly to be sure.
