To design a BMS for your high voltage stationary battery, start by selecting one of these 2 topologies or contact us for help:

  • Wired, VinciNet: A wire to each cell, wireless to the Master
  • Distributed, VinciBus: A module on each cell, fiber-optic to the Master

The BMS uses a Master/Slave topology; the Battery Master communicates with its Slaves wirelessly through radio waves.

Cell sensing is wired: each slave senses the voltages of its cells through a number of tap wires.

Isolation is provided by the wireless link.

The BMS consists of:

  • A VinciNet Battery Master and an Application module
  • A number of VinciNet Slaves
  • Up to 2 current sensors
  • A set of contactors
  • To manage an array of batteries as a single unit, an Array Master

VinciNet topology

The BMS uses a Master/Slave topology; the Battery Master communicates with its Slaves through a 5-wire VinciBus.

Cell sensing is distributed: a cell module is mounted on each cell to sense its voltage and temperature; each slave manages a bank of up to 25 cells through 2 fiber optic cables.

Isolation is provided by the fiber optics.

The BMS consists of:

  • A VinciBus Battery Master and an Application module
  • A number of VinciBus Slaves
  • Up to 2 current sensors
  • A set of contactors
  • To manage an array of batteries as a single unit, an Array Master

Feature Comparison
Cell sensing
Distributed vs wired
Wired: For N cells, N+1 voltage tap wires go from the slave to the cells. Distributed: Cells are divided into banks of up to 25 cells.
A cell module is mounted on each cell.
Two optic fibers go from the Slave to the two cell modules at the to ends of the bank.
Slave to Master VinciNet
Wireless communications between the Master and the slaves.
VinciBus.
A parallel bus (5-wire) goes from the master, connects each module (slaves and application module), and ends in a terminator.
HV isolation Between the Master and the slaves, through a wireless link. Between the cell modules and the slave, through fiber optics.
Pros & cons
Pros
  • No cables in battery
  • 1 thermistor / cell
  • RF immunity
Cons
  • Only two thermistor / bank
  • Possible RF interference
  • Fiber optic cables in battery
