Battery

As mobile demands continue to grow, batteries have become an integral part of our daily lives. From security cameras to computers, drones, motorcycles, and even buses, batteries are essential for powering these applications. The batteries used in these applications undergo extensive testing during development and production to ensure they meet real-world demands safely.

The Vitrek 95x Series Electrical Safety Analyzer is designed to perform critical tests such as dielectric strength testing, insulation resistance testing, ground testing, and low-resistance ground continuity testing. These tests are mandated by safety standards and international regulations (e.g., IEC, UL, EN) to ensure the safety of battery products. For instance, testing the insulation properties of aluminum casings and the dielectric strength of battery modules to ground are essential for guaranteeing safety.

The Vitrek PA900 Power Analyzer provides high-precision measurements and recording of power parameters. Equipped with high-precision current sensors, it captures real-time data during high-current charging or discharging cycles.

Traditionally, battery charging is done using programmable DC power supplies, while discharging is achieved using electronic or resistive loads. Today, bidirectional DC power supplies can perform both functions. This not only saves costs and valuable rack space but also allows the energy discharged from the battery to be fed back into the local grid, enhancing energy efficiency.

The Elektro Automatik EA-PSB Series Bidirectional DC Power Supply goes a step further. It functions both as a DC power supply and a regenerative electronic load, seamlessly switching between the two modes. It absorbs energy during battery discharge and feeds it back into the grid, reducing energy consumption and operational costs for testing facilities.

At VASTi Technologies, we assist in selecting the right equipment and provide guidance on building robust battery testing systems. Our expertise ensures the safety of all testing equipment and the devices under test, while also offering operational guidance and best practices.

Bidirectional DC power supplies are inherently well-suited for emulating batteries because they can both supply and absorb power. By implementing operating profiles that mimic specific battery types, test engineers can accurately replicate battery states of charge to test devices that charge from or receive power from batteries. Elektro-Automatik's battery emulator software can simulate both lead-acid and lithium-ion batteries, including their electrical and chemical characteristics during charging and discharging.

In collaboration with the renowned German Fraunhofer Institute, EA has developed battery emulation algorithms backed by years of research. This allows for the emulation of a set of battery cells at a very specific state of charge (SOC) in just a few minutes, rather than waiting for the batteries to charge or discharge to the same SOC. The software also takes into account factors such as battery capacity, internal resistance, ambient temperature, and even the health status (SOH).
