Charging, Discharging and Evaluating (SOH) of Battery Modules and Battery Packs

AVL DiTEST rightCHARGE 11 kW

The traction battery is the most valuable component of an electric vehicle. To ensure the longest possible service life for the traction battery, we have developed the AVL DiTEST rightCHARGE 11 kW for you. The rightCHARGE 11 kW is our latest product for conditioning battery modules.

It enables fast and safe repair of various battery types: If an individual battery module in a traction battery is defective, it must be replaced with a new one. After the faulty battery module has been identified, it must be removed from the traction battery. In the next step, the state of charge (SoC) of the new battery module is adjusted to match the state of charge of the remaining battery modules within the traction battery. The battery management system (BMS) will only activate the repaired traction battery if the states of charge are similar. Therefore, conditioning new battery modules is absolutely essential in order to reinstall the new battery module into the traction battery and complete the repair process.

Features

  • Safe application due to high-precision monitoring:
    • Intelligent contact detection
    • Reverse polarity protection
    • High-precision permanent monitoring of cell voltages, temperature, and charge/discharge currents
    • Display of critical parameters during the charging/discharging process
  • Guided user interface and automatically generated log
  • Freely selectable target voltage or state of charge
  • Communication with the battery module via 24 analog channels (expandable using accessories) or digital protocols (CAN, CAN-FD, SPI, and ISO SPI)
  • Measurement of the residual capacity of the battery module using coulomb counting (SOH)
  • Control of the device via AVL DiTEST software or API
  • Unplugging the PC during the charging/discharging process
  • Equalization of cell voltages within the battery module (either analog or digital)

USPs

  • High charging performance & currents (max. 11 kW & 80 A)
    The rightCHARGE 11 kW enables the conditioning of battery modules in the shortest possible time. Example: Charging a 36s27p battery module from 25% to 80% SoC takes approx. 40 minutes.

  • Wide voltage range (2 – 430 450 VDC)
    The rightCHARGE 11 kW enables charging of battery modules between 3 – 400 VDC and discharging between 2 – 430 VDC. This makes it capable of conditioning a wide variety of battery modules, both for BEVs and PHEVs. Combined with the AVL DiTEST HV SAT, even the entire battery pack can be charged or discharged.

  • Energy recovery into the power grid
    In addition to discharging the battery modules via the heating element, the rightCHARGE 11 kW enables the recovery of the discharged energy. For this purpose, the energy taken from the battery module is fed back into the power grid (once approved by the local grid operator). This allows you to reduce your net energy demand and energy costs. Compared to discharging via the heating element, energy recovery accelerates the discharging process considerably.
