Re: Axiam Mega Van - Hydrogen Fuel Cell as replacement for the battery

WIth a lead acid the higher the rate of discharge the faster the voltage drop, the faster the rate of voltage drop the higher the current. Thats why lifepo4 etc are so good because they dont suffer the constant voltage drop so performance and current can be well controlled. Lifepo4 etc can deliver 3...

Re: Axiam Mega Van - Hydrogen Fuel Cell as replacement for the battery

Its not that easy. 1. you have a selector to choose low or high performance (Thats relative) in the cab, 2. The 8 cell version will not only have lower range but lower performance as the lead cells have a limited discharge rate. The higher the current the greater (Rate of drop and voltage) the volta...

Re: Axiam Mega Van - Hydrogen Fuel Cell as replacement for the battery

The safety issue is that of the integrity of the hydrogen container in a vehicle accident. If they get damaged the result is a significant destructive explosion. So far the Tanks for vehicle use are either generic small containers, or seriously costly specially made devices. As to the Aixam, the mot...

Re: Axiam Mega Van - Hydrogen Fuel Cell as replacement for the battery

Yes three lines of 4 battery, some installed from under the rear floor and some inserted from under the passenger seat. Its a steel frame slung between the chassis rails. As with any fuel cell vehicle you will still need a battery pack to start the vehicle and deal with the peak demands. Why a fuel ...

Re: Velo Advance Community E-bikes crowdfunding bid

Forget the PR, Just explain what it is you are trying to do. Save the PR for the crowd funding . You have as much space here as you need to explain what you want to do and how the money would be spent. Can I suggest some headings. What is the project called. Who is involved. Where will it be located...

Re: Velo Advance Community E-bikes crowdfunding bid

I have read and re read this as well as the funding site, which has the same text, and I really dont understand what you are trying to do. Is this a project to build ebikes? if so what is the specifications to be, who is to buy them what expected quantities, and how will the marketing be carried out...

Re: Allied Peugeot Boxer charging

Thats certainly not the Allied EDN charger, it wont do below 207v on single phase. ANd they were staggeringly expensive so I doubt anything like that is in yours.
What is the charger in your Buggy? Send me some pics.

Re: Allied Peugeot Boxer charging

I suppied a type two to 3phase cable for a chap who drove his Boxer from scotland down to Cornwall. He wanted Type 2 3ph to speed his journey, but its not that common a feature of public charge points.He actually found more sites , like farm shops with std 3 ph than public charge points. On the Alli...

Re: Allied Peugeot Boxer charging

The plug used the extra pins to act as a pilot and if you unplugged the van end of the cable, you broke the circuit and the main contactor in the wall outlet turned off the power. Neat but unusual. I now have the remains of the EV parts and the reason the vehicle was dead was a duff cell in the pack...
