Battery Test and Simulation Expertise
We can source and sink power at 96% efficiency
Batteries have become a huge part of our daily lives. Electrical and electronic devices are becoming increasingly mobile, meaning that batteries are required to power everything including computers, drones, automobiles, and buses. The batteries used in these products require significant testing during development and production to ensure they will meet real-world demands.
Traditionally, engineers used programmable DC power supplies to charge batteries and resistive or electronic loads to discharge them. Today, a single instrument—the bidirectional, regenerative power supply—can perform both tests. Using a bidirectional, regenerative power supply saves equipment costs and valuable rack space, as well as energy costs by regenerating the energy from a discharging battery back into the local grid.
The EA Elektro-Automatik PSB Series can transition seamlessly between providing DC power to charge batteries and sinking DC power during discharge cycles. The energy it sinks from a discharging battery can then be put back into the local grid, saving both energy and heating costs for the testing facility. And, EA’s DC power supplies and loads come standard with pre-installed battery test software for both lithium-ion and lead-acid batteries to make setting up and running your battery tests even easier.

Application Solutions
Battery Testing
Battery technology is becoming increasingly sophisticated, as batteries get smaller and become increasingly efficient. To keep up with these changes in battery technology, your battery test equipment must also be advanced, flexible and responsive. For these reasons, the PSB bidirectional programmable DC power supply series by EA Elektro-Automatik is a perfect fit for advanced battery testing.
The PSB bidirectional supply can seamlessly switch between charging batteries under test and discharging them in a controlled manner. Battery charge, static discharge and dynamic test functions are included with PSB, PSI, EL and ELR product series, or you can program the PSB to perform custom charge and discharge cycles if you have special requirements. In either case, EA can help you specify just the right equipment and provide basic guidance on how to build a robust system that will effectively and safely test your product’s batteries.

Electric vehicles (EVs), such as e-bikes, hybrid cars and trucks, and full-electric vehicles need medium- or high-power battery chargers during development and testing. These battery chargers are frequently used as part of a battery test system that performs cycle, performance and age tests. These test rigs usually include control, monitoring and safety mechanisms tailored to the type of battery under test.

Battery Recycling
Sustainability in electromobility is a major challenge
To make electromobility sustainable, second-life concepts and efficient recycling of lithium-ion batteries and lithium-ion polymer batteries will play a key role in the very near future. Completely new industries and companies are emerging to take on this task.
EA-BT 20000 TRIPLE
Optimize your battery recycling with EA
Regenerative loads and bidirectional programmable DC power supplies from EA Elektro-Automatik make your battery recycling:
- efficient
- flexible
- economical
- safe
- sustainable
Second-life use
Bidirectional DC lab power supplies test the remaining capacity of your batteries
The primary goal is to find a second use for the batteries from electromobility after they have been used in the vehicle (second-life use). For example, as energy storage for solar power or wind energy. When testing the remaining capacity, the battery is first fully charged and then discharged in a controlled manner. The capacity (SOC) and state of aging (SOH) are measured and the energy is fed back into the power grid with an efficiency of over 96%.
The bidirectional programmable DC power supplies from EA Elektro-Automatik are ideally suited for this process.
Final recycling
Electronic loads with mains feedback for the complete discharge of your accumulators
After the second-life cycle, the rechargeable batteries are subjected to final recycling. This process attempts to recover as many components of a lithium-ion battery as possible as raw material for new batteries. Before the batteries are disassembled into their individual parts, they must be fully discharged. This is done in order to avoid the risk of contact-hazardous voltage or fire and to use the residual energy still stored in the battery.
EA Elektro-Automatik’s regenerative electronic loads are a very efficient solution for this purpose.
