E-mobility and Energy Applications.

EV charging Infrastructure

To charge an EV battery, the alternating current (AC) – typically 230 VAC and 50 Hz in Europe from the network grid must be converted to direct current (DC). When the EV is plugged into the AC grid, the conversion is done by the converter embedded within the car. When the EV is plugged into a DC outlet, the power conversion is embedded within the charging station.

As the price of batteries decreases, car manufacturers increase battery capacity:  they offer a longer driving range (>400 km) and faster charging options (up to 350 kW). The EV fast charging infrastructure then becomes essential to support EV market growth. Watt & Well is providing power modules and Supply Equipment Communication Controllers (SECC) that are critical subsystems of DC charging stations.

As an innovative e-mobility electronics supplier, Watt & Well delivers advanced power modules and Supply Equipment Communication Controllers (SECC) — essential subsystems for DC charging stations.

Smart Grid Energy Stationary Storage (ESS), Mobile Energy Storage (MES) and V2G

Smart grid technologies are an alternative to the replacement or reinforcement of electric grids. Solutions such as Energy Stationary Storage (ESS), Mobile Energy Storage (MES) and Vehicle-to-Grid (V2G) provide flexible and distributed energy buffers to help integrate renewable energy sources and better manage the grids.

As an experienced e-mobility power electronics provider, Watt & Well contributes to the ESS/MES/V2G ecosystem by delivering high-performance bidirectional AC/DC converters. These modules enable efficient charging and discharging of batteries, managing energy flow between storage systems and the grid, and supporting a wide range of energy services.

We can also provide Electric Vehicle Communication Controller (EVCC) to be integrated in systems that need to be charged according to CCS protocol such as Energy Storage System, Electric Vehicle, electric truck, electric boat and could be also used to recharge a mobile battery at a DC charging point.
