3.3kW on-board charger for small electric vehicles

Delta-Q Technologies XV3300 battery charger

Called XV3300, it will be available in 58.8V, 65V, and 120V models and can be combined in multiples up to 20kW.

“Our team included a dc-dc converter for auxiliary dc loads, a VCIM [vehicle charge interface module] for connection to public EV charging, and the ability to stack the chargers for configurable power levels. We achieved all this in a 3.3kW charger that is over twice as compact as our previous models,” said company engineering v-p Steve Blaine.

Envisioned auxiliary include air-conditioners, controllers, lights, turn signals, navigation and communication devices.

According to the company, it can charge “all battery chemistries” and nominal voltages between 48 and 120V, and it is protected against short-circuit, over-voltage and over-temperature.

The charging station interface complies with SAE J1772 (levels 1 and 2) and IEC 61851 (modes 2 and 3) to charge from standard EVSE AC charging stations across North America and Europe.

Communication is over CAN bus and will have regulatory approvals, including touch-safe requirements for the European electric vehicle market.

The aluminium die-cast enclosure is IP67-rated and tested for automotive-grade shock and vibration.

Production is scheduled for for the first half of 2022.
