Pareto Frontier of the Ragone Plot

What battery packs are at the pareto frontier of the Ragone plot? With a database of over 300 packs we can plot power gravimetric density vs energy gravimetric density.

Koenigsegg Regera Battery

Koenigsegg Regara

The Koenigsegg Regera is a PHEV with a combined power of 1,119kW and uses a 4.5kWh 800V liquid cooled battery. The battery is designed by RIMAC.

Rimac Nevera

NIO ES6 150kWh

The 150kWh NIO ES6 is ground breaking for a number of reasons and perhaps 260Wh/kg at pack level is not the most significant.

As with most pareto frontiers the technology and design moves on and in the world of battery pack development this is relentless.
