As with many things the authorities give little attention to or concern about caravans.....they remain pretty well unregulated in most counts.
likewise DC power supply applications in cars and boats are pretty well unregulated.
Its only with the proliferation of
grid connect solar, that the DC section of the Australian Electrical Standards applying to buildings has grown to a significant size.
Fact is caravan fires are fairly common.
As for VW beetles....yeh well they burn pretty easily too, and in the day fairly commonly ...remember the beetle was mostly manufactured before we had Australian Design Rules, the early models had neither
seat belts nor indicators.....by current safety standards the VW Beetle would fail on a string of counts
AND, in restoration, one of the most common parts for beetles is a replacement floor section where the battery is stored..corroded due to acid damage..
If you want to look at
places where battereies ARE specifically regulated.. aviation, off shore yachting, shipping required to be surveyed (that includes small commercial craft) and various institutional battery users, those regulations have rather a lot to say about how batteries are housed.
Where the batteries are housed.
How the batteries are to be housed.
What type of battery is permitted
Ventilation
Location of switch gear outside of battery comprtments
ALL issues discussed in this thread.
Recreational boating is very similar to Caravans, very similar methods are used, the issues and the disregard are pretty well the same.
It is very common to see batteries housed in the cabin under the bed in recreational boats.....this would not be permitted in a boat for commercial use required to be surveyed.
If the very reasonable electrical requirements that apply to boats for commercial use where applied to recreational boats the vast majority would fail...on multiple counts .....most of them would fail on on battery location and housing alone.
Every summer we see news reports of recreational boats large and small burning to the water line..." for no apparant reason"...for anybody with eyes to see and ears to hear the reasons are dogs balls obvious.
Poor electrical standards and unwise storage of flamabes.
The very same issues I post about concerning cars and caravans.
As for the exploded caravan picture.
follow the discussion....the batteries themselves may not have exploded....but the most likely source of the type of explosion would be hydrogen from the batteries.
If the explosion would have been either petrol or LPG gas, fire would have most likely have followed..and it did not.
