pmski Posted April 13, 2016 Report Share Posted April 13, 2016 Looking for advice on what petrol generator will power the charger for my Freeride E. I know it's not a trials bike but there is so much knowledge on here regarding E bikes. So I want to take the bike to my local MX/Enduro bike park, they don't have electricity so I can't recharge between rides. I can easily get 60 mins+ continuous ride time when I am not gassing it MX style so my plan is ride for a hour, have lunch and recharge the bike, then ride for another hour, and repeat. The charger needs 13 A steady output to fast charge, and 10A steady for normal charging. I found this article that talks about charging the battery with a petrol generator on the KTM blog, so it's doable. Had a look at generators, would this be suitable - its the 13/10A steady output that I am not sure about as it doesn't specify that in the specifications. Any advice on what type of generator I should consider greatly appreciated. Thanks Quote Link to comment Share on other sites More sharing options...
gwhy Posted April 13, 2016 Report Share Posted April 13, 2016 that gen will output a constant of around 11A @ 230v Quote Link to comment Share on other sites More sharing options...
gwhy Posted April 13, 2016 Report Share Posted April 13, 2016 you would be better off looking for a low voltage DC generator to charge the battery directly instead of using the 240v mains charger... what voltage is the battery on the ktm? i.e what is the voltage output of your charger ? 1 Quote Link to comment Share on other sites More sharing options...

The battery needs the charger to manage the charging process - can't direct charge. Don't know what voltage the battery is, but found this which may help? Electric motor Permanent magnet synchronous motor in a disc armature design Rated output 7.5 kW (10.1 hp) Max. power 22 kW (30 hp) Traction battery Lithium-ion (easily removed) Rated voltage 300 V Quote Link to comment Share on other sites More sharing options...
pmski Posted April 13, 2016 Author Report Share Posted April 13, 2016 How much is a second battery? Way too much - over £2k Quote Link to comment Share on other sites More sharing options...
heffergm Posted April 13, 2016 Report Share Posted April 13, 2016 Way too much - over £2k Wow... scratch that idea. Quote Link to comment Share on other sites More sharing options...
gwhy Posted April 13, 2016 Report Share Posted April 13, 2016 Wow is the battery really 300v !! Im very supprised at that as its a off road bike. Scape the idea about a direct dc charger as you will still need to boost even 240v even higher Quote Link to comment Share on other sites More sharing options...
copemech Posted April 14, 2016 Report Share Posted April 14, 2016 What type Honda generators do they sell there. Here a EU2000 will do it and quietly, but they are 120V here. 13A is 13A, even in 240V Quote Link to comment Share on other sites More sharing options...
pmski Posted April 14, 2016 Author Report Share Posted April 14, 2016 Wow is the battery really 300v !! Im very supprised at that as its a off road bike. Scape the idea about a direct dc charger as you will still need to boost even 240v even higher The bike is fast, I mean proper angry fast when it's on power mode 3 so I would assume this is correct. So if I want a generator that will output 13A consistently at 230v what would you recommend? Quote Link to comment Share on other sites More sharing options...
pmski Posted April 14, 2016 Author Report Share Posted April 14, 2016 Would this Generator be suitable? Wolf Power Quote Link to comment Share on other sites More sharing options...
floydbassman Posted April 14, 2016 Report Share Posted April 14, 2016 The Wolf generator is lower output than the Clarke generator in your 1st part of this thread, Be careful with stated outputs of generators from different manufacturers. They sometimes advertise the peak output instead of the continuous output, which is the max output it can cope with all day long. Peak output drawn for too long may damage the generator`or cause annoying tripping of its overload protection. Quote Link to comment Share on other sites More sharing options...
timdog Posted April 14, 2016 Report Share Posted April 14, 2016 Have you considered a spare car battery with dc inverter? Workes for an Oset without the noise/expense of a generator or just connect to car/van battery Quote Link to comment Share on other sites More sharing options...
crazybond700 Posted April 14, 2016 Report Share Posted April 14, 2016 What if you charge it with a less powerfull generator? Will it be slower, or would it not work? (depends on the charger I quess). Quote Link to comment Share on other sites More sharing options...
reggie Posted April 14, 2016 Report Share Posted April 14, 2016 I think what you really need to look at the the input specifications of the charger that came with your bike. Quote Link to comment Share on other sites More sharing options...
