Arc

We model how batteries behave, from the cell up.

Arc builds Lachesis: a physics-based model that shows how a cell behaves in your application. Its heat, performance, and ageing.

About Arc

No two battery applications are the same.

A datasheet describes a cell under standard conditions. In your product it sees its own load, cooling and pressure, and behaves differently. Finding that out with prototypes is slow and expensive.

We built Lachesis to see it before you build it.

LACHESIS

Everything that shapes your cell. Predicted every cycle.

Lachesis splits the cell into small elements and calculates the current, heat and ageing in each of them.
