• Additional Safety and Reliability Features: Includes cell sensing-wire disconnection protection, charging lockout when any cell voltage is at or below 1.5V, and electrostatic discharge (ESD) protection rated at ±4kV contact discharge and ±8kV air discharge. Designed for operation in ambient temperatures from -20°C to 60°C (-4°F to 140°F).
• Limitation: The BMS does not support digital communication, external discharge-switch control, or series/parallel connection of completed battery packs. It is intended for 13S lithium-ion configurations, and compatibility with battery packs other than the specified design should be confirmed before installation.

Wiring Connection and Installation:

Overview

• The Tenergy PN32206 Battery Management System is designed for 13-series (13S) lithium-ion battery packs. It features a common-port configuration, individual cell voltage monitoring, passive cell balancing, and multiple electrical and temperature protection functions.
• The BMS requires proper connections to the battery pack terminals, cell voltage sensing wires, and compatible temperature sensors to provide its specified protection functions.

Main Power Connections

The charger and load share the P− connection. The positive terminals of the charger and load connect to the battery pack positive terminal (B+).
Important: B− and P− serve different functions and must not be connected together externally in a way that bypasses the BMS protection circuit.

Cell Voltage Sensing Connections

PN32206 uses two connectors for monitoring the individual cell voltages in a 13S battery pack.

CN2 – 11-Pin Connector (2.0mm Pitch)

CN1 – 7-Pin Connector (2.0mm Pitch)

All cell voltage sensing connections must match the manufacturer's specified pin assignments.

Temperature Sensor Connections

NTC Sensor Requirements:

• Nominal resistance: 10kΩ ±1% at 25°C
• B-value: 3435K ±1% (25°C/85°C)
• Connector: 4-pin, 2.0mm pitch

Temperature sensors should be securely positioned at appropriate monitoring locations within the battery assembly, with proper electrical insulation.

Additional Connectors

• CN3 – 2-Pin Connector: Reserved for an optional low-current switch function. This function is not required or supported in the specified PN32206 configuration.
• J1 – Programming Interface: Four-pin programming connection designated for manufacturer programming and servicing. Not intended as a general-purpose communication interface.

Installation Precautions

• Confirm that the battery pack uses a compatible 13S lithium-ion configuration.
• Verify all terminal assignments and sensing-wire connections against the manufacturer's specification before applying power.
• Prevent reversed polarity, crossed sensing wires, and accidental short circuits.
• Ensure the PCB is securely mounted and electrically insulated from battery cells and conductive surfaces.
• Use compatible NTC sensors and verify the temperature monitoring configuration.
• Use a compatible 54.6V lithium-ion charger with charging current limited to 2.5A.
• Do not exceed the specified 15A continuous discharge current.
• Protect the BMS from water, condensation, excessive humidity, and electrostatic discharge.
• Do not modify the PCB, components, or protection circuitry.
• Before placing the assembled battery pack into service, verify correct charging, discharging, and protection operation.

Professional Installation Required: This BMS is intended for qualified battery pack assemblers and technicians familiar with lithium-ion battery safety. Incorrect installation can cause battery damage, electrical hazards, fire, or personal injury.

Compatibility Note: The supplier specification does not support series or parallel connection of completed battery packs equipped with this BMS. Digital communication is not supported.
