Important Safety Information
The content in this document must be followed in order to ensure safe operation of Nuvation
BMS™.
Do NOT energize the system until all connections to the Cell Interface and
Power Interface modules have been made.
Insulated handling is required of any connector carrying potentials over
600Vdc relative to chassis.
Properly insulate or remove any unused wires. Unused wires can couple
excessive system noise into Nuvation BMS which can disrupt
communication and lead to undesirable behaviors.
Please be aware of high voltages present in your system and follow all
necessary safety precautions.
The provided module enclosures are not fire enclosures.

Depending on battery chemistry, there might be a nominal voltage per cell
which adds up in series and is always present. There are many different
battery chemistries with different current capacities, and so high voltage
with high current capacity may be present while connecting the Nuvation
BMS. You must use proper electrical safety precautions when handling any
part of the Nuvation BMS. Neither Nuvation Energy or any of its employees
shall be liable for any direct, indirect, incidental, special, exemplary,
personal or consequential harm or damages (including, but not limited to,
procurement or substitute goods or services; loss of use, data, or profits; or
business interruption) however caused and on any theory of liability,
whether in contract, strict liability, or tort (including negligence or
otherwise) arising in any way out of the use of this product.

The Nuvation BMS relies on your system charger to charge the battery
cells; do not leave your charger off while the Nuvation BMS is powered from
the stack for prolonged periods of time. The Nuvation BMS should be shut
down when the system is in storage to minimize the drain on the cells.

3. Nuvation BMS™ High-Voltage Stack Controller
3.1. Overview
The Nuvation BMS™ High-Voltage Stack Controller module monitors and controls all Cell Interface
modules in a single battery stack. The built-in Stack Bus receives power and communication from
the Power Interface module. The Link Bus provides power and communication for all connected
Cell Interface Modules. Ethernet, CAN and RS-485 (Modbus) are included. No high-voltage or
high-current interfaces are present on the Stack Controller, making this module easy and safe to
connect to for service operations.
There is only one model of the Stack Controller, the NUV100-SC.
3.2. Mechanical Dimensions
The overall dimensions of the Stack Controller are 104.4mm X 121.58mm X 40.6mm.
It comes standard with DIN clips that enable the Stack Controller module to be securely mounted
to EN50022-compliant DIN rails. The clips add an extra 19.6mm to the overall width of the Stack
Controller module, bringing it from 104.4mm to 124mm. The clips also hold the module
approximately 7mm away from the inside lip of the DIN rail.
Extra space should be provided around the module to allow for easy installation/maintenance.
The Stack Controller weighs approximately 525g.

3.3. Electrical Connections
The Stack Controller module has 7 connectors. Each connector is described in the following
sections in detail.
3.3.1. Link Out
The Link Out connector provides power and communication to the Cell Interface modules. The
amount of current supplied by this connector is the sum of current consumed by all Cell Interface
modules in the system. Connect the Cell Interface module which is measuring the most negative
cell in the stack to this connector.

3.3.2. CAN 485
The CAN 485 connector contains both isolated CAN and non-isolated RS-485 (Modbus)
connections. Isolated CAN requires 5.5-12V sourced from an external power supply to operate.
120Ω termination for CAN is added by connecting pins 3 and 9 together. 150Ω termination for
Modbus is added by connecting pins 6 and 12 together.
Keep the termination wire length short for best results. Connect external equipment to this
connector.

3.3.6. Stack Bus
The Stack Bus connector accepts power and provides a communication channel from the Power
Interface. The Stack Bus provides 42mA to the SC plus the summation of current consumed by all
Cell Interface modules in the system (25mA per CI-12 or 31mA per CI-16). 120Ω termination
must be added by connecting pins 1 and 3 together with a short length of wire.
Connect the Power Interface module to this connector.

4. Nuvation BMS™ High-Voltage Cell Interface
4.1. Overview
The Nuvation BMS™ High-Voltage Cell Interface connects to the battery cells and temperature
sensors. The Cell Interface monitors and balances the cells, sends cell data to the Stack Controller,
and prevents overheating or overcharging of cells.
There are three models of the Cell Interface.
•The NUV100-CI-12, Cell Interface - 12 channel can monitor up to 12 series-connected cells
•The NUV100-CI-16, Cell Interface - 16 channel can monitor up to 16 series-connected cells
•The NUV100-CI-4M12, Cell Interface - 12V 4 channel can monitor up to 4 series-connected
12V lead-acid cells
4.2. Mechanical Dimensions
The overall dimensions of the Cell Interface are 104.4mm X 121.58mm X 40.6mm.
The Cell Interface comes standard in a bulkhead-mountable enclosure. The enclosure has five
metal walls, leaving the bottom of the unit fully exposed. It must be mounted to a metal bulkhead
panel so that the panel will become the missing side. The module will produce up to 24W (32W if
it is the NUV100-CI-16 model) during cell balancing. A portion of this heat will be transferred to
the bulkhead.
Extra space should be provided around the module to allow for easy installation/maintenance.
The Cell Interface is also available in an enclosure with DIN clips that enable the Cell Interface
module to be securely mounted to EN50022-compliant DIN rails. The clips add an extra 19.6mm
to the overall width of the Cell Interface module, bringing it from 104.4mm to 124mm. The clips
also hold the module approximately 7mm away from the inside lip of the DIN rail.

The Cell Interface can contain high-voltage signals, with the maximum voltage
possibly reaching as high as 1250Vdc. Care must be taken when mounting the
PCB into a metal enclosure to ensure that the metal walls remain a safe distance
from the exposed conductor on the PCB.
Using the 1250Vdc as an example, the metal walls must be at least 4.2mm from
the nearest exposed conductor and not touch the PCB or any component on the
PCB, including the connector housings.
A Cell Interface with DIN mountable enclosure weighs approximately 540g and a Cell Interface
with bulkhead mountable enclosure weighs approximately 450g.

4.3. Electrical Connections
The Cell Interface module has four connectors. Each connector is described in the following
sections in detail.
4.3.1. Link Out
The Link Out connector provides power and communication to the Cell Interfaces above this Cell
Interface. The amount of current supplied by this connector is the sum of current consumed by all
Cell Interfaces above this Cell Interface.
Connect the Cell Interface that is measuring the next series-connected cell above the most
positive cell connected to this connector.

Interfaces below this Cell Interface, or from the Stack Controller if this Cell Interface is measuring
the most negative cell in the stack.
The amount of current sourced into this connector is the sum of current consumed by this Cell
Interface and all those above it (which amounts to all Cell Interfaces if this Cell Interface is

Connect to the Link Out connector on the Cell Interface that is measuring the previous series-
connected cell below this Cell Interface to this connector, or connect the Stack Controller to this
connector if this Cell Interface is measuring the bottom cell in the stack.

4.3.3. Battery Cells
The Battery Cells connector provides cell voltage input and a means for balancing the cells. The
cable wire should be rated for at least 750mA to survive worse-case current.
Pins 8, 16, 17, and 18 are No Connect in the Cell Interface - 12 channel model. Pins 2, 4, 6, 8, 10,
11, 12, 13, 14, 15, 16, and 17 are No Connect in the Cell Interface - 12V 4 channel model.
All unused voltage inputs should be tied to the next highest potential voltage sense input. In this
way, all pins should be connected with the exception of pins 8, 16, 17 and 18 in the Cell Interface
- 12 channel model and pins 2, 4, 6, 8, 10, 11, 12, 13, 14, 15, 16, and 17 in the Cell Interface -
12V 4 channel model.
Connect the battery cell voltage sense leads to this connector.
