3.1. Multi-Stack System Architecture
A typical multi-stack system, equipped with Nuvation Energy’s suite of BMS products, is illustrated in
. There is a hierarchy of battery management involved, each product fulfilling its role at a
different level:
▪
At the cell level, a Nuvation Energy Cell Interface module measures voltage/temperature and
balances cells as required.
▪
At the stack level, a Nuvation Energy Stack Switchgear unit measures current and
connects/disconnects its stack as required, as well as incorporates other stack safety features.
Battery safety is handled at the stack level.
▪
At the system level, a Nuvation Energy Battery Control Panel unit manages all stacks as described
above.
For a given stack, the daisy-chained Cell Interface modules report data to and receive direction from
the Stack Switchgear. In turn, the Stack Switchgear reports data to and receives direction from the
Battery Control Panel. Here, a unified view and central control of the multi-stack system is provided
to the user as well as any external devices.
Nuvation Energy Cell Interface modules and Nuvation Energy Stack Switchgear units
are sold separately. Datasheets, along with product manuals, are available online at
