Charging and discharging battery modules

AVL DITEST rightCHARGE 11 kW

Your traction battery is the most valuable part of the electric vehicle. In order to extend the life of the battery as long as possible, we have developed the AVL DiTEST rightCHARGE 11 kW for you. The rightCHARGE 11kW is our latest battery module conditioning system.

It allows you a fast and safe repair of different types of batteries: When an individual module in a traction battery gets defective, you need to replace it. After identifying the defective battery module, you must remove it from the battery pack. In the next step, you have to adapt its SoC (State of Charge) according to the SoC of other modules in the battery. Otherwise, the BMS (Battery Management System) will not activate the repaired battery. Hence, the conditioning of new battery modules is crucial, to successfully install the new module into the battery pack and finalize the repair process.

Features

  • Safe operation based on a high-precision monitoring:
    • Intelligent contact detection
    • Reverse polarity protection
    • High-precision, permanent monitoring of cell voltages, temperature, and current
    • Safety indication based on moduledependent limits
  • Guided software workflow and automated protocol function
  • Adjustable target voltage
  • Communication with the battery module via 24 analog channels (freely expandable via accessory box) or digital protocols (CAN, CAN-FD, SPI, and ISO SPI)
  • Measuring the residual capacity of battery modules via coulomb counting
  • Operated via Windows interface or device API
  • Allows disconnecting the PC or tablet while conditioning battery modules
  • Balancing of cell voltages (analog or digital)

USPs

  • High power and max. current (max. 11 kW & 80 A)
    The rightCHARGE 11 kW allows conditioning battery modules in a short period of time. For example, a 36s27p-module could be charged from 25% to 80% SoC in about 40 minutes.

  • Broad voltage spectrum (2 – 430 VDC)
    The rightCHARGE 11 kW allows charging modules from 3 – 400 VDC and discharging modules from 2 – 430 VDC. Based on its significant voltage spectrum, the rightCHARGE 11 kW is able to condition different types of battery modules, either from BEVs or PHEVs. Combined with AVL DiTEST’s HV SAT, it could even be used to charge or discharge battery packs.

  • Energy recovery via bi-directional power electronics
    Besides discharging energy from battery modules via heat dissipation, the rightCHARGE 11 kW allows discharging via energy recovery: Energy, discharged from the battery module, is fed back to the power grid (if enabled by local grid specifications). Thereby, you can decrease your net energy demand and save energy costs. Furthermore, discharging battery modules is much faster compared to dissipation.
