Jump starts in the future?

Post by MarkHawkins » Mon Oct 30, 2017 8:40 pm

At the weekend my Discovery donated some electricity to get an engine turning over - not an uncommon use for a large 4x4. Parked near by was a Nissan Leaf. It got me thinking - will electric car users be able to share charge if a driver is 'caught short'?

A bit dodgy linking the cars together - over 200 VDC can do you a lot of harm - if you survive in the first place ( not good odds ) that is.

I've jump started a car off a Leaf, you use the 12V battery under the bonnet, not the high voltage system!!!!

The manual says not to jump another car from the 12v battery in the Leaf - you can jump/boost the Leaf 12v battery if that's flat though.

Oops, didn't read the manual, it was only car around at the time to jump start the scimitar, worked really well.....

Was Mark's original question actually aimed at conventional petrol or diesel jump starting (with or in, hybrids), or was he talking about all-electric vehicles "sharing" charge in some way?

It was the thought of sharing charge between EV's when one was stranded.

You shouldn't jump start another car from a Nissan Leaf. The PDM and DC/DC converter wont like it. Unless trained (I am a Leaf trained technician) and having the correct equipment you should never go near the cables in orange casings... there's a 400 volt suprise waiting for you if you do.

As a Leaf trained man do you know if anyone else has had training - thinking about firemen, police and ambulance people who are likely to be first on site of a accident.

Do Nissan supply the insulated shepherds crook for hooking people out of the car as I've seen in the F1 teams

I did the training for Leaf as part of my Master Technician training when the car was first launched. On the course we raised that exact same question and we were told at the time that the emergency services were supposedly going to get the same safety training as we got. Whether they did though, I don't know.

I've never seen or heard of Nissan supplying one.

I saw the title and thought this was going to be about Deloreans, Mr Fusions and flux capacitors. Never mind...

straying off topic but the TESLA has a BIG sticker next to the main power lead that has 'cut here in emergency'

I assume that's done with insulated bolt cutters? or stay well away from the car-body as you do so :shock:
