Electric Vehicle Energy (eVe) Transformers
Delta Transformers Inc. is pleased to announce the launch of their new EVE series transformers, dedicated to EV charging station applications. EVE transformers offer a complete solution of transformation products to meet any EV charging station technical requirements, installation challenges, and environmental conditions.
With the growing demand for electric vehicles and EV charging stations, Delta EVE transformers offer voltage adjustments between the utility services and the EV charging station for both single-phase and three-phase systems.
Delta EVE series transformers are available in ventilated enclosures and epoxy-potted versions for harsh environments. Optional Type 4, stainless steel enclosures, and even Type 3R enhanced version with snow filter and thermal sensors are available. Other options include custom paint colours and tamper-proof hardware.
Complete customization of Delta EVE transformers includes voltages (up to 27.6kV class), kVA sizes, and a range of temperature rises. With various EV charging stations available on the market, this product meets the requirements of level 1, 2, and fast-charging electric vehicle installations.
Three Levels of EV Charging
Some national standards (Ex: CAN/CSA-C61000-2-2-04 R2014) may set limits on the amount of harmonics that can be returned to the power grid. This harmonic transmission can be reduced to compliant levels by various transformer designs, including features such as phase shifting, use of electrostatic shields, zig-zag windings, or other harmonic mitigation devices.
High Harmonics
Based on the harmonic spectrum generated by the charging architecture of a DC fast charger, we recommend a K-factor of 9. On systems with level two chargers, a K-factor of 4 can be used.
Cosmetic Integration
Custom assorted (white, blue, red, green, and other colors) or stainless steel enclosures are available for easy cosmetic integration with other OEM electrical equipment.

Advantages of “EV” Rated Transformers
- Rated for EV charging applications when loading varies from many hours of idling, to periods of heavy demand (helping to drive down building energy consumption)
- Low ‘No-load losses’ for efficiency during a long idling period meeting or exceeding CSA C802.2-18 requirements
- Aluminum winding for a greener product, copper version also available
- Non-brittle Epoxy Vacuum Impregnation coating (the EVI© process) remains flexible and can handle the thermal expansion/contraction movements of the coils during load and temperature fluctuation without cracking
- Long-term reliability and long-life expectancy
- CSA Efficiency Verified
- NOMEX-based insulation system resisting up to 220°C
- Custom units are available to meet your project and technical requirements.
