16S DC 48V home energy storage system BMS motherboard
Product Description
1.board overview
Shiningintl SH3081 BMS motherboard is suitable for the management of 8S-16S lithium batteries, employing an integrated design
that integrates functions such as collection, management, and communication. It can provide protection functions such as overcharge, overdischarge, overcurrent, overtemperature, undertemperature, and short circuit protection for lithium battery packs, as well as voltage balancing during charging. It can store information
such as charge and discharge voltage and current and communicate through communication ports. Parameters can be configured and data monitored through upper computer software. It can be widely used in indoor and outdoor base
stations, energy storage, and other fields.
2.Function Features

Shiningintl SH3081 BMS board supports Single cell voltage and total voltage detection, overvoltage and undervoltage alarm and protection functions.
2.2 Current Detection and Protection Function
Charging and discharging current detection, alarm, and protection functions. Charging current is displayed as
positive, and discharging current is displayed as negative.
2.3 Temperature Detection and Protection Function
Battery cell, ambient, and PCB temperature detection functions, with alarm and protection during high and lowtemperature charging and discharging.
2.4 Short Circuit Protection Function
Detection and protection function for output short circuit.
2.5 Reverse Connection Protection Function (Optional)
Detection and protection function for charger reverse connection.
2.6 Activation Wake-Up Function
Multiple activation wake-up functions: charger activation, RS232 communication activation, reset button activation
2.7 Buzzer Alarm Function
Buzzer alarm function.
2.8 Dry Contact
Two dry contact relays: can control the output of two switch signals.
2.9 Heating Film Function
Heating film function, supports heating film output with a current of less than 5A; with heating film circuit short
circuit secondary protection and heating film MOS failure protection functions.
2.10 Secondary Protection Function
Secondary protection function, with external secondary protection tripping control output interface and tripping
status detection function.
2.11 Anti-Theft Function (Optional)
Acceleration anti-theft function.
2.12 Hardware Watchdog
External hardware watchdog reset function.
2.13 Charging Current Limiting Function
Supports 10A charging current limiting function.
2.14 Battery Pack Capacity Calculation Function
Accurate calculation of battery pack SOC through current and time integration. Battery pack full capacity and
current capacity can be set through the upper computer software, and the capacity can be automatically updated
after a complete charge and discharge cycle.
With charge and discharge cycle count function, when the accumulated discharge capacity of the battery pack
reaches 80% of the set full capacity, the cycle count increases by one.
2.15 Cell Charging Balancing Function
Can balance unbalanced cells during charging: when the highest cell voltage reaches the start balancing voltage
during battery pack charging, and the maximum voltage difference is greater than the balancing voltage difference,
the balancing function of the corresponding single cell is activated.
Balancing activation voltage and balancing voltage difference can be set through the upper computer software.
2.16 LED Indication Function
With 9 LED indicators, including 6 green indicators for battery level indication to indicate the current battery pack
SOC, 1 red indicator for fault indication to indicate alarms and faults, 1 green running indicator to indicate the
standby, charging, and discharging status of the battery pack. 1 green indicator displays the state of the weak power
switch.
2.17 Historical Record Storage Function
With historical record storage function, storage capacity of no less than 10,000 records. Storage time period, time
interval can be set, and storage content adopts the first-in-first-out principle. The storage content can be read and
stored as an Excel document through the upper computer software.
2.18 Communication and Parallel Function
Equipped with RS485 communication function, RS232 communication function, CAN communication function can
realize parallel use of battery packs, communicate with external inverters, and monitor the status of BMS and
battery packs in real-time. Battery pack parallel address is compatible with automatic and manual settings.
2.19 Upper Computer Control Function
With a user-friendly upper computer interface, you can conveniently set protection parameters such as overvoltage,
undervoltage, overcurrent, overtemperature, undertemperature, short circuit, balance, sleep, capacity, storage, and
various alarm parameters through the upper computer
