Battery Management System (BMS) Communication Monitoring and Debugging Toolkit

KIT-TPLSNIFEVB Active

Roll over image to zoom in

The BMS communication monitoring and debugging toolkit is used to monitor and decode BMS internal communication. It is composed of separate hardware and software components.

The KIT-TPLSNIFEVB hardware board facilitates the acquisition of electrical transport protocol link (ETPL) signals by a logic analyzer. It is a listen-only tool that can be used at the end of an ETPL bus or directly included in a daisy chain, as it is designed not to be intrusive on the ETPL bus.

The TPL Decoder is a high level analyzer (HLA) extension for the Saleae Logic Software. It eases decoding of the NXP TPL protocols on several physical layers.

Features

Power and Data Connections

  • Connection to any point of the monitored TPL bus
  • Logic analyzer connection with a provided cable pin-to-pin compatible with the Saleae Logic 8 and Logic Pro 8/16 analyzer series
  • Powered through a USB connector by a 5 V source, typically a USB power bank or a USB cable connected to a computer

Additional Features

  • Minimal loading of the TPL line
  • Internal galvanic isolation between the TPL and rest of the circuits
  • Integrated keep-alive function to avoid power bank self shut-off
