Charging mobility scooter on EHU

[Suenliam]

We are thinking seriously of getting a mobility scooter to enable Liam to "walk" as far as he used to particularly in France. These will not be too far as I will be really walking
The scooter supplier has been very helpful and we have narrowed his needs down to 2 similar models, the difference being different battery sizes. I'm told that one scooter battery is 12v 20ah and the other one 12v 12ah. We always use sites with EHU but would we be able to charge the batteries overnight particularly on continental campsites with limited amps?
I don't have an instruction manual with full electrical details, but if more information is needed the supplier (a local shop) would be able to provide this for me.
I am sure the answer is simple either way, but the only thing I know about campsite electricity is approx 240w = 4amps which doesn't seem to relate to the information I have.
Thanks
Sue

Just had a look at my scooter charger.
Input 240v 1.8 amps
Output 24v 8 amps

I would be checking the batteries.....most scooters have two 12v batteries wired in series so 24v.

In a word, yes.

They aren’t huge batteries so should be fine even on a 6 amp hookup.

You would need to check the specification of the charger though.

240watts at 240volts equals 1 amp, not 4 amps.

4 amps is around 1000 watts

 

[Suenliam]

Sorry pappajohn - meant to say 240 w x 4 = 1kw approx = 4 amps

I'll check the spec. of the scooter charger.
Thanks everyone

Checked with the supplier and the scooter charger is 1.8amps so will suit any campsite supply (even in France!)
We are going to hire the scooter for a short trip away later in the month and if it fits into our campervan without too much problem we will purchase it with the hire charge deducted from the total price.
Typically bad timing - we have just down sized to a campervan from a much larger coachbuilt, but hey ho!
Thanks for everyones' help.

I would think that once you have turned everything off except your fridge and ready for bed, just plug in your scooter batteries to charge overnight. Can't see any issues with that.

 

[Suenliam]

Exactly what we intend to do

I'm told that one scooter battery is 12v 20ah and the other one 12v 12ah.

20Ah is quite a small battery. Even if it was a lithium battery, charging at a maximum rate of 20A, that's still only 240W which is 1A from the EHU. It shouldn't be any problem at all.

If it was charging at 4A, that's at 12 volts, so the watts is only 12 x 4 = 48W. At 240V that would be 48 / 240 = 1/5 of an amp from the EHU.

Charging batteries overnight is not recommended

My scooter instructions say charge overnight!

 

[PaulC70]

Wife always charges her mobility scooter overnight and the one we've just bought for the camper will similarly be charged overnight. As for ebikes, you'll find that its usually the cheap crap that decides to burst into flames or lack of following instructions :-(

This is mainly because of people buying cheap unmatched chargers/batteries etc.

I bought two 36v 17ah batteries that came with matched chargers, absolutely no heat generated when being charged with the air cooled chargers supplied.

The OPs batteries are indeed quite small for mobility scooter. Both my scooters have a pair of 95ah AGMs and the charger output is 10amp.

Depends on the scooter though. The travel one the wife now has is a 24v 15ah Li-ion, charger is 3.5amp

Thanks again for everyones' interest and advice. The proposed scooter although 4 wheels and stable is light weight and will do about 8 - 10 miles on a battery charge. This will suit us very well as I will be walking along side and don't do long distances any more!
I too have read about the dangers of charging overnight when using mismatched chargers and cheap imports.

For the last 6 years my wife has used an elite traveller plus. Scooter breaks into 4 bits & stows easily.
It has 2 x 17ah batteries in a removable battery unit. We have two of these, one in use & one on charge.
batteries are usually recharged while on the move or from solar when possible.
we have a 12 to 24v b-b charger. Recharge can take a day!
when on site we recharge from mains, never had a problem anywhere in uk or eu.
range is very dependant on surface, slope & weight of passenger but 5-10 miles is doable.

Invest in a buggy board and you can travel behind.
