aandncaravan Posted February 5, 2017 Share Posted February 5, 2017 We have almost finished a new page on the website explaining how some Motorhome battery chargers work, which is not as most people believe, and how just a small increase in habitation battery size can take the charger into a mode where charging can take forever. Obviously with a big impact on the batteries themselves. It tries to clarify why making a motorhome habitation battery bank over large can have such a catastrophic effect on some 230v mains chargers/power units and the batteries. Even burning some out. As per most of the website the page is about information sharing, no sales pitch, no advertising. We have tried to explain the science, but as usual for me it's not the most readable There are some great technical people on here, who are also able to make themselves understood better than I. I would very much appreciate any feedback help?. http://www.aandncaravanservices.co.uk/how-does-a-charger-work.php Thank you. Link to comment Share on other sites More sharing options...
AlanS Posted February 5, 2017 Share Posted February 5, 2017 The web article on how some motorhome chargers work is very good and I think reasonably easy to read for those who have less technical knowledge. I would like to point out though that in fairness to Sargent equipment, you make no mention of their PX300 charger which is an 'intelligent integrated charger' with both variable voltage and current output. Their more modern EC400 to EC 600 Power Supply Units (from 2009 to toady) encompasses this technology on the charger side. They certainly are not dinosaurs in the field as your article may suggest. I am not involved with Sargent in any way other than having their EC500 units in my last 2 motorhomes and am very pleased with them - especially as we are linked to solar and have dual habitation batteries as well as the vehicle battery of course. As for BCA you mention - we have had these in previous caravans we have owned with catastrophic results and we certainly were not alone in this.

aandncaravan Posted February 5, 2017 Author Share Posted February 5, 2017 Alan, thank you. Good point, we specialise in repairing/rebuilding the Sargent EC325 after Sargent stopped support for it. It is an excellent unit, very advanced with well designed and built electronics, so you are right we should balance that on the web page. I have made a quick alteration to the web page, but might have another look at it tomorrow. Link to comment Share on other sites More sharing options...
