About CycleWatt
Turn a battery end-of-life problem into local energy infrastructure.
CycleWatt is a French deep-tech company developing whole-pack second-life battery systems, diagnostic tools and energy-management capabilities.
“A vehicle battery can keep delivering useful energy long after its first mobility life.”
Our mission
We extend the productive life of qualified EV batteries while helping industrial, mobility and renewable-energy sites access flexible local power.
CycleWatt brings together battery diagnostics, whole-pack integration, power conversion, system control and energy management. At the end of second life, the battery returns to the recycling chain.
