Lithiumate™ controllers

Masters and High Voltage Front Ends (HVFE)

Elithion offers a range of Li-Ion Battery Management System controllers to form the core of a Li-Ion BMS.

Master only

  • Required
  • Manage the battery
  • Communicate with cell boards and with the rest of the system
  • Optionally, may be connected to an HV Front End through the CAN bus
  • Two versions: Pro (also available at the board level)
    and HD. See table below for differences

HVFE only

High Voltage Front Ends:
  • Optional
  • Lets the controllers perform certain tests before turning on contactors
  • May include an on-board current sensor
  • Available at the board level, or encased
  • Communicates with the BMS controller through the CAN bus
A Remote HV Front End:
  • Keeps the high voltage away from the BMS controller
  • Keeps any electrical noise away from the BMS controller
  • May simplify the layout of high voltage cabling

Masters with HVFEs

High Voltage Front Ends:
  • A master and a High Voltage Front End in a single enclosure
  • The HV Front End includes circuits that are connected to the Battery and are therefore at high voltage. Putting those circuits on a separate board improves safety in the BMS controller and reduces the chance of electrical noise interference to it.

This table lists all the available controllers.

Note: * = An external current sensor, is required, unless the battery current value is already present on the CAN Bus.
