Who is Hi Performance Electric Vehicle Systems

Hi Performance Electric Vehicle Systems (HPEVS) designs, develops and manufactures 3-phase AC induction drive systems for an array of vehicles and industries. These systems have been integrated into full-sized vehicles, neighborhood electric vehicles, golf carts, motorcycles, industrial/utility vehicles and even amusement park attractions. These systems are designed to achieve maximum distance, power and efficiency.

New to Building Your Own Electric Vehicle?

If you are new to the EV world and need a great reference guide, HPEVS suggests purchasing Eric Kriss's comprehensive how-to printed guide on converting a vehicle to electric. The book is based on the conversion that took place in 2012 of a 1969 Saab Sonett, but the information can be translated to any vehicle.

Kriss sonett

The book covers all the new technologies, including HPEVS motors, lithium battery packs and digital instrumentation. The book also includes an extensive appendix and complete wiring diagrams.
