Second-life use for batteries

Second-life use for batteries

Battery testing made easy with bidirectional programmable DC power supplies

Testing for Second-Life use
What is the residual capacity of the battery?
The potential uses of second-life batteries from electric vehicles are many and varied. The applications range from home storage, emergency power supplies and power buffers to energy storage for solar power or wind energy.

For this application, it makes sense to use bidirectional laboratory power supplies for further investigation. With only one device, it is possible to test whether older batteries from electrically powered vehicles can still be used in other applications. If these applications are predominantly static and if the residual capacity is sufficient, these batteries will find their second-life use e.g. in stationary energy storage systems.

In this test, the battery is first fully charged with the bidirectional power supply and then discharged in a controlled manner with the same device. 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%.

Your advantages when using bidirectional programmable DC power supplies from EA Elektro-Automatik

  1. High efficiency and higher safety when testing the battery capacity
    Bidirectional programmable DC power supplies from EA Elektro-Automatik ensure the maximum possible charge and discharge of the batteries. With precise tests, detailed data about the remaining capacity is provided for the DUT.
  2. Amortization through power regeneration
    The bidirectional programmable DC power supply from EA Elektro-Automatik takes its energy from the connected battery during the discharge process and converts it into AC voltage with an efficiency of up to 96%. This is then fed back into the local power grid and reused, thus amortizing the purchase price via reduction of electricity costs.
  3. Economy through time savings
    The time saved in charging and discharging the lithium-ion batteries using the high input powers of up to 15kW in 3U enclosures or 30kW in 4U enclosures increases cost-effectiveness. In addition, the devices can be combined to form high-performance switchgear cabinet systems with a total output of up to 1.92MW.
  4. High flexibility in use
    Versatile and flexible: Due to true autoranging capability of the device series from EA Elektro-Automatik, battery storage systems with different system voltages can be charged and discharged with only one bidirectional programmable DC power supply. For example, full power is available with one device for both a 400V and 800V system.
