2. History and Personnel
Founded in 1991 by electrochemist Dr. John Zhang, who saw the need for more accurate and reliable, rugged test systems for electrochemical storage devices. Starting from a garage, the company grew into a multinational enterprise with a 65,000 sq. ft. in-house manufacturing facility in the heart of Texas. In 2019 it formed a partnership with Metrohm Autolab to develop integrated solutions for battery research, and in 2025 was selected as the supplier of high-current battery test systems for Ambri’s liquid-metal battery pilot production.
Dr. John Zhang remains the principal owner and part of leadership today, and the company states it reinvests roughly half of its profits into R&D. It maintains offices and agents in Germany, China, India, Vietnam, South Korea, and Taiwan.
3. Core Technology and Key Equipment
For more than 30 years the company has manufactured multichannel charge/discharge test equipment spanning nanoampere-level precision electrochemical measurement up to 1MW-class systems for grid-scale batteries. It supports everything from materials research to testing across a range of energy-storage devices, including batteries, capacitors, and flow batteries.
- RBT-Cell series — high-precision regenerative test systems
- High-channel-density multifunctional cyclers (for both R&D and production)
- EV cell testing; half-cell, full-cell, and symmetric-cell test solutions
