If this also entails a 5x improvement in weight, let's see if that potentially enables hand luggable car batteries.
- Nissan Leaf 62 kWh battery: 410 kg= 6.61 kg/kWh
- order of magnitude for this type of battery: 1.32 kg/kWh
- power consumption: @15 kWh/100 km
- 100 km requires 15 kWh, or ~19.80 kg
If something like this in order of magnitude comes true, hand luggable batteries will be able to cover non-trivial distances. Some potential consequences:
- I imagine something like this could help enable a low-end, more maintainable second hand market in a not-so-distance future.
- For inhabitants of terraced town houses, this could enable them to charge their batteries at home too. Hand luggable batteries could simplify _a lot_ in terms of charging infrastructure.
- Exceptionally far trip? Throw in a few extra modules.

- alias_neo 5y agoThis was the electric car future I always envisioned. Some sort of twist-lock cylinder that one fits into one of several slots in the vehicle depending on the range they require. I'm not your how safe that would be, nor would I really want to be charging a 15kWh+ battery inside my home if I lived in a terraced house as GP suggests.
- markvdb 5y agoYou'd be 100% right to be wary of charging this kind of battery inside your terraced home until it has thoroughly proven itself to be fire safe. The terrace or the garden shed might provide a safe alternative though.
