Automated testing systems now use bidirectional power supplies that combine charging and discharging in one unit, streamlining battery testing, and returning energy to the grid to boost efficiency and cut waste.
As global decarbonization efforts accelerate, the demand for advanced battery systems is rising, driven by electric vehicles (EVs) and renewable energy storage. The need for robust battery testing equipment has grown in parallel with advances in battery technology. From cell development to end-of-line validation, manufacturers now view testing as critical to delivering performance, reliability, and safety.
EVs require longer range, faster charging, and improved safety, which has led to new chemistries and cell designs—each requiring rigorous testing. Stationary storage, for grid balancing or solar and wind integration, demands reliable systems with long lifespans and consistent performance. Testing characterizes cells, modules, and packs for capacity, thermal behavior, and durability.
The rise of automated, high throughput testing systems is helping to meet demand. Manufacturers typically begin by procuring core products—mainly power supplies—to simulate real-world conditions. These are then integrated into complex systems by battery OEMs to adapt to evolving designs and testing needs.
A key innovation is the adoption of bidirectional power supplies. Unlike conventional setups, these perform both charging and discharging through one connection and return energy to the grid.
“Bidirectional power supplies deliver power and absorb energy,” says Andrew Engler of Intepro Systems. “This dual capability enables seamless transitions between charging and discharging cycles.”
Cinergia’s systems, distributed in North America by Intepro, deliver AC and DC output from a single unit. Models from 7.5 kW to 160 kW can be paralleled for over 1 MW. Three independent outputs enable simultaneous multi-battery testing.
For lower power systems—such as e-bikes or home storage—Intepro offers Delta Elektronika’s DC power systems. Delta’s 15 kW blocks scale to 300 kW, with high efficiency, long life, and fast delivery times.
Bidirectional supplies reduce energy waste, minimize heat buildup, and cut cooling costs, supporting both large EV packs and smaller consumer systems.
