SAJ has made a remarkable contribution in the Green Revolution by designing and manufacturing Innovative test solutions for the ELECTRICAL VEHICLES and today SAJ is a preferred partner for developing diverse Test solutions for 2,3,4 Wheelers, EV Hub/ BLDC Motors, EV Transaxles, EV Roller Test Benches and Shower Test Chambers etc.

Hence SAJ is aptly called a “ONE STOP SHOP for TOTAL TESTING SOLUTIONS”

Objectives of EV Test Rigs

• EV Test Rigs are mainly developed for Research and Monitoring of the propulsion drives of Electric Vehicles.
• These type of testing are suitable for investigating the dynamic loads and processes in the propulsion drives.
• These Test Rigs provide durability and functional tests to the customers and help to solve many other propulsion defects.
• The main objective of an EV testing is to complete Durability test, routine Performance test and road condition simulation test of the Electric Vehicle.
