Charged EVs | WattEV’s new Strong-State Transformer improves energy conversion for heavy-duty electrical truck charging

WattEV presently operates 5 truck charging depots in California, and has one other 15 websites beneath growth. The corporate is eager on the brand new Megawatt Charging System commonplace for heavy-duty EVs.

Now WattEV has launched a brand new compact medium-voltage energy conversion system (MV-PCS) designed to speed up deployment of MCS quick chargers.

WattEV’s Strong-State Transformer (SST) was developed as a alternative for step-down transformers, switchgear and low-voltage rectifiers. The brand new system is designed for handy set up on service islands between pass-through lanes providing megawatt charging to MCS-capable vans.

As WattEV explains, in contrast to standard 480-volt programs, the MV-PCS’s built-in design considerably reduces set up prices by having the utility medium-voltage line at 12 kV to fifteen kV cut up by way of junction bins and related instantly into the liquid-cooled SST cupboard.

“As fleets work towards MCS deployment, complicated tools stacks and provide chain points together with tariffs change into actual constraints,” stated Salim Youssefzadeh, CEO and co-founder of WattEV. “The SST is designed to deliver MCS to heavy-duty depots quicker and extra cheaply.”

WattEV says its new SST can velocity up website growth and cut back set up and upkeep prices by changing a number of items of apparatus with a single built-in system. It permits direct conversion from 12 kV-15 kV to DC with variable voltage and present at 1.2 MW to three.8 MW.

WattEV has accomplished its proprietary SST design and expects production-ready models to be obtainable in 2026.
