Renault today lifted the lid on two innovations based on its EOLAB prototype, both of which are scheduled to appear in production cars in 2015. At the same time the innovative French company has revealed three longer-term approaches to low-fuel consumption, low-emissions mobility.

All were unveiled at an [email protected] event in Paris, where the company’s Co-operative Innovations Laboratory (LCI) – a think tank that unites engineers, designers and customer survey specialists – gave a behind-the-scenes peek into how Renault powertrains and propulsion systems might evolve in the next few years.

Of interest to us here at Speak EV is a new, compact electric motor – designed and made entirely by Renault – delivers similar performance to those in use today but is around 10 per cent smaller. It is a synchronous unit with a wound rotor and delivers 65 kW (88hp) and 220 Nm of torque. It was designed by Renault’s motor engineers in France and manufactured in Renault’s Cléon plant.

Renault has switched from macro-module stacking to fully integrated modules, assembled closely so that no external power supply cables are necessary. The junction box and integrated Chameleon charger (as fitted to ZOE) are contained within a single Power Electronic Controller, which is 25 per cent smaller than existing systems.

The motor is now air-cooled, simplifying the system with only the Power Electronic Controller continuing to be cooled by water. Improved electronic management reduces charging times using the 3kW and 11kW flexi-cable, while a redesigned inverter improves efficiency and reducing power consumption.

Interesting stuff. I wonder if the version 2 Zoe will feature this motor?

Interesting that there's water cooling. Is that used for passenger cabin heating? I'd assumed the Zoe's heat pump heater was air to air.

Possibly explains the firesale Yeah!

88hp electric motor is plenty for the Zoe due to its size and weight. Nice to see they are pushing the development of the EV components.

Wow Deja vu! almost a repeat of our experiences with our Zoe for the first three months of ownership with one acceptation, I note that they haven't blamed you yet as in our experience everyone and everything got the blame except Renault or the Zoe this included my wife and I being blamed for plugging Zoe's charge cable in to quickly:confused:.

What cured our Zoe was a charge control computer software reload with the latest software version at that time but I would imagine that your Zoe should have the latest software installed.

They have. I neglected to mention it. Once for doing it too abruptly, and once for doing it too gently... :rolleyes:o_O
You have got to be joking.:mad: How are you not spitting feathers? I would have demanded my money back plus extra for the inconvenience you have been put through. Does Renfault not know the damage that they are doing to what IMO is a really good looking car with a reasonable range in todays market. I will not even think about a Zoe untill their charging fiasco is not sorted.

Update via Transport Evolved... No more 43 kW rapid charging with the new motor.

Odd decision?!

Not necessarily. The story also mentions an improved battery pack and 'up to 18 miles' range improvement.

I'd be interested to know how many Zoe owners have actually used 43 kW rapid charging and how often.

If the improvements do result in a range of say 110 miles on a good day in summer, the hour it takes to fully recharge at 22 kW isn't too much of a trade off when on a longer trip.

It could be that the changes to the inverter will improve its compatibility with public chargers.

Seems sensible - they have struggled to make the low-rate charging work so if they make that work and also get a range boost by dropping the rapid charge then it is a big win for them.

110 miles of real range is inching closer towards the point where you aren't stopping for a "splash and dash". Not there yet though.

Can't quite fathom how regen works though - the Leaf does 30kW regen according to the display. If Zoe uses the same circuitry to charge ...?
