Examples
Block diagram

⇐ Wired cell topology, daisy-chained slaves ⇒

The traction pack is fully self contained.
A 12-cell slave is mounted by each group of 12 cells and wired to the cells.
A VinciLink goes from the master to the first slave; additional VinciLinks go from slave to slave.
A VinciBus goes from the master to the application module.

Components:

  • 96 cells in series in 8 banks
  • Vinci-EV Battery Master, VinciLink
  • Vinci-EV application module
  • 8 x VinciLink slaves, dissipative, 12-cell
  • Contactor set with precharge and current sensor

Split pack example: a 2-wire cable is run from the last slave in the first battery to the first slave of the second batery.

Wired cell topology, bussed slaves

The traction pack is fully self contained.
A 12-cell slave is mounted by each group of 12 cells and wired to the cells.
A VinciBus goes from the master to the application module and to each slave.

Components:

  • 96 cells in series in 8 banks
  • Vinci-EV Battery Master
  • Vinci-EV application module
  • 8 x VinciBus slaves, dissipative, 12-cell
  • Contactor set with precharge and current sensor

Split pack example: the VinciBus is run from the Master (outside the batteries) to the first battery, then to the second battery.

Block diagram

Distributed cell topology

The traction pack is fully self contained.
A cell board is mounted on each cell.
Cables go from the ends of each block of 25 cells, to a slave.

Components:

  • 100 cells in series, in blocks of 25 cells
  • Vinci-EV Battery Master
  • Vinci-EV application module
  • VinciBus slave, 4-bank
  • 100 cell boards
  • Contactor set with precharge and current sensor

Split pack example: 2-wire cables are run from one slave (outside the batteries) to each battery.
