Renault Twingo ZE battery - how it amazes me! [column]

I have been following this topic for several days. Recently introduced the Renault Twingo ZE, a small electrician from segment A. Have you noticed how tiny its battery is? Or maybe this is not visible at first glance? If not, compare these charts.

Renault Twingo ZE Batteries

Here is the Renault Twingo ZE battery in the top view. If you compare this diagram with the rendering below, you will notice that we have one can located under the front seats. Smart ED / EQ powered by Twingo is similar, but not the point.

That's all the battery has a capacity of 21,3 kWh... Renault is reporting usable capacity for now, so we expect the total battery capacity to be around 23-24 kWh, which is roughly the size of the first Nissan Leaf and slightly less than the first-generation Zoe. So let's take a look at the battery sizes of these cars:

Twingo ZE again:

Renault Twingo is the A segment, Renault Zoe is the B segment, Nissan Leaf is the C segment. The Renault Twingo ZE battery is microscopic compared to a few years ago.

Renault brags that it was used in it. latest generation LG Chem cells (NCM 811? Or maybe NCMA 89 already?), In addition, it was used in it Water coolingwhich is easy to find out if you look for tubes on the diagram. The battery consists of 8 modules. voltage up to 400 volts i weighs 165 kilograms... The first generation Renault Zoe air-cooled battery weighed 23,3 kg with a usable capacity of 290 kWh.

We've lost ~ 10 percent of our capacity, and we've lost over 40 percent of our weight!

Now let's take it one step further: The Tesla Model 3 battery weighs 480 kilograms and offers approximately 74 kWh of usable capacity. So, if Renault and LG Chem had Tesla technology, the battery could weigh about 140 kilograms and be about 15 percent smaller. Here, what progress has been made over the past 10 years: instead of a large container taking up 1 / 3-1 / 2 of the chassis, we can store ~ ​​24 kWh of energy in a small box under the seats.

With the technology at Tesla's disposal, that would be around 28 kWh. For such a kid, this is real 130 or 160 kilometers. Today. In a small drawer under the seats. How much will it be in the next 10 years? 🙂

I can't help but admire the progress that is happening before our eyes. Knowledge of 2-3 years ago is outdated, knowledge of 10 years ago is already archeology and excavations 🙂
