Battery Formation

Formation can take 10–20 hours or more per cell and must be performed on every unit with tight current and voltage accuracy. As battery demand scales, this slow, energy‑intensive step limits factory throughput and accounts for a significant share of equipment cost and floor space, especially in high‑volume EV and energy storage manufacturing.

Battery formation equipment functions as a large, multi‑channel switched‑mode power supply platform. Power electronics enable ultra‑precise current and voltage control, high parallelism across thousands of channels, and efficient handling of both charge and discharge energy, which is essential for accuracy, scalability, and energy efficiency in modern formation lines.

Bidirectional architectures recover energy during cell discharge and reuse it within the system or feed it back to the grid. Instead of dissipating discharge energy as heat, regenerative designs dramatically improve system efficiency, reduce cooling requirements, and lower operating costs, enabling round‑the‑clock operation with much higher overall energy utilization.

Wide‑bandgap devices such as SiC and GaN enable higher switching frequencies, lower losses, and higher operating temperatures. This translates into higher power density, improved efficiency, smaller passive components, and reduced cooling requirements, all of which are critical for compact, scalable, and energy‑efficient formation systems.

A typical system includes an AC‑DC front end with power factor correction, an isolated high‑power DC‑DC stage, and multiple low‑voltage bidirectional DC‑DC output channels. Together, these stages enable efficient grid interfacing, galvanic isolation, precise cell‑level control, and energy recovery during discharge.
