Battery Charging

During the development and testing phases, electric vehicles (EVs) like e-bikes, hybrid cars, and full-electric trucks require medium- to high-power battery chargers. These chargers often integrate into a comprehensive battery test system designed to conduct cycle, performance, and age tests. Such test setups typically feature customized control, monitoring, and safety mechanisms suited to the specific battery type being tested.

Battery Simulation

Use EA's bidirectional DC power supplies to simulate lead-acid and lithium-ion batteries

Bidirectional DC power supplies are ideal for battery simulation due to their dual capabilities of sourcing and sinking power. Elektro-Automatik’s Battery Simulator software enhances this by enabling accurate simulation of both lead-acid and lithium-ion batteries, replicating their electrical and chemical characteristics during charge or discharge cycles. This technology allows test engineers to precisely emulate battery power for devices that either charge or draw energy from batteries.

In collaboration with Germany’s esteemed Fraunhofer Institute, EA Elektro-Automatik crafted algorithms based on years of research to simulate batteries with a high level of accuracy. These algorithms enable quick simulation of battery cells at specific states of charge (SOC), eliminating the need to wait for actual charging or discharging. The simulations can be customized using various parameters such as battery capacity, internal resistance, ambient temperature, and even state of health (SOH).

Battery Recycling

Addressing the major challenge of sustainability in electromobility

To pave the way for sustainable electromobility, the efficient recycling and second-life applications of lithium-ion and lithium-ion polymer batteries will soon become critical. New industries and companies are emerging to tackle this challenge. EA Elektro-Automatik’s EA-BT 20000 TRIPLE series enhances your battery recycling process by offering regenerative loads and bidirectional programmable DC power supplies that make the process efficient, flexible, economical, safe, and sustainable.

Battery Life Cycle and EA Deployment Devices

Second-life Use

Maximize Battery Second-Life Use with Bidirectional DC Lab Power Supplies

The ultimate aim is to repurpose electromobility batteries for second-life applications, such as energy storage for renewable sources like solar and wind power. To assess the remaining capacity, batteries are first fully charged and then systematically discharged. During this process, both the state of charge (SOC) and the state of health (SOH) are measured, and the energy is efficiently regenerated back into the power grid at an efficiency rate exceeding 96%. EA Elektro-Automatik’s bidirectional programmable DC power supplies are perfectly engineered for this task.

Final Recycling

Unlock Full Battery Discharge with Regenerative Electronic Loads

Once rechargeable batteries reach the end of their second-life cycle, they undergo a final recycling process aimed at reclaiming as many components as possible for new lithium-ion batteries. Before disassembly, these batteries must be fully discharged to mitigate risks like hazardous voltage or fire, while also utilizing any residual energy. EA Elektro-Automatik’s regenerative electronic loads offer an efficient solution for this critical step in battery recycling.
