Second generation NMC cells in Renault Zoe

Renault Zoe

 

What do we already know about LG Chem battery achievements?

 

I have the information that the second generation NMC cells that will be used, have 65 Ah capacity and weight less than 1 kg. This means an energy density a little more than 240 Wh/kg.

These LG Chem cells will make the Zoe have a 300 km real world range, or more than 400 km in the unreliable NEDC.

We can expect the future Zoe to maintain the number of 192 cells in the battery pack. Let’s do the math: 192 x 65 Ah x 3,75 V = 46,8 kWh

 

People worried about the charging time shouldn’t, future Zoe will be able to charge at 100 kW DC with CCS (Combined Charging System). Should also maintain the ability to charge at 22 kW AC or even 43 kW with its internal chameleon charger.

 

I predict that Chevrolet Bolt will have a similar battery pack. Weight and aerodynamic of the car will dictate the range difference in relation to Zoe.

    Hello Pedro. who is the source of this information?

    Tnaks.

      Hello Fernando.

      This information about the new cell’s characteristics and CCS charging actually comes from different sources that work for LG Chem and I regard them both as reliable.

      Since Samsung SDI advertised their new cells in Frankfurt Motor Show, I think that there’s no problem in sharing this bit of information. I actually find strange that LG Chem doesn’t advertise their cells more. Every cell maker is doing it, even cells that are years away, from solid state, sulfur to lithium-air.

    Hello Pedro,
    the current Zoe R240’s Chameleon charger already dropped 43kW charging, leaving 22 kW AC as the max supported charging power.

    In terms of product strategy at Renault, I doubt the Zoe to get this much in kWh and range as you predict. To me it’s more likely that a future Zoe might get only 96 of those new 65Ah cells in a 96s1p configuration, and remains with 23 kWh and the price is reduced. In addition, this would save battery weight (from 290 down to roughly 170 kg due to packaging), which then translates to slightly more range in city traffic.

    More upper-class cars at Renault-Nissan, such as the Leaf, will then eventually get the 46 kWh battery pack.

    Your sources at LG may experience the cells to be used in the Zoe for testing, but this can be a mule application. 🙂 This does not imply that the same config will also be available for sale later on.

    To me, it also seems unlikely, that those 65Ah pouch cells are the same size and weight as the 32.5Ah pouch cells used in the Zoe up to now. Do you have information on cell dimensions?

      Hello Ralf K.

      Thanks for your messages.

      Unfortunately I have no information about the volumetric density of the new 65 Ah cells.

      In March, at the 86th Geneva International Motor Show we’ll have more information.
