EMU1101-Home Energy Storage Lithium LFP/NMC

(1) Cell and battery voltage detection

Real time collection and monitoring of series battery cell voltage to achieve over voltage and under voltage alarm and protection of battery cells. Voltage detection accuracy of battery cells ± 10mV at 0-45 ℃ and ± 30mV at -20-70 ℃.Alarm and protection parameter settings can be changed through the upper computer.

(2) Battery charging and discharging current detection

By connecting the current detection resistor in the main charging and discharging circuit, the real-time collection and monitoring of the charging and discharging current of the battery pack is achieved to achieve charging and discharging current alarm and protection, with current accuracy better than ± 1%.Alarm and protection parameter settings can be changed through the upper computer.

(3) Short circuit protection function

It has the detection and protection function of output short circuit.

(4) Battery capacity and number of cycles

Real-time calculation of remaining battery capacity, learning of total charge and discharge capacity at one time, SOC estimation accuracy better than ±5%. The setting value of the battery cycle capacity parameter can be changed through the upper computer.

(5) Equalization of intelligent single cells

Unbalanced cells can be balanced during charging or standby, which can effectively improve the service time and cycle life of the battery. The balanced opening voltage and balanced differential pressure can be set by the upper computer.

(6) One-button switch

When the BMS is in parallel, the master can control the shutdown and startup of the slaves. The host must be dialed in parallel mode, and the dial address of the host cannot be turned on and off with one key. (The battery reflows to each other when running in parallel, and it cannot be turned off with one key).

(7) CAN, RM485, RS485 communication interface

CAN communication communicates according to the protocol of each inverter, and can be connected to the inverter for communication. Compatible with more than 40 brands.

(8) Charging current limiting function

Two modes of active current limiting and passive current limiting, you can choose one according to your needs.

1. Active current limiting:When the BMS is in the charging state, the BMS always turns on the MOS tube of the current limiting module, and actively limits the charging current to 10A.

2. Introducing our latest innovation in battery management systems, the advanced BMS with passive current limiting. Designed with cutting-edge technology, this product is set to revolutionize the charging experience and ensure maximum safety for your battery.

One of the key features of this BMS is its passive current limiting capability. In the charging state, when the charging current surpasses the charging overcurrent alarm value, our BMS will automatically activate the 10A current limiting function. This means that in the event of excessive current flow, the BMS will take immediate action to protect your battery from potential damage or overheating.

Furthermore, after activating the current limiting function, the BMS will reassess the charger current after 5 minutes. This ensures that even if the initial current limiting is not sufficient, the BMS takes another step to prevent any potential harm. By constantly monitoring and adjusting the charging current, our BMS guarantees optimal charging conditions for your battery and extends its overall lifespan.

What sets our BMS apart is its open passive current limit value, which can be easily adjusted to meet your specific requirements. This flexibility allows you to customize the current limiting function according to the characteristics and needs of your battery. Our BMS empowers you to have full control over the charging process, ensuring that it operates within safe and efficient parameters.

With safety as our top priority, this BMS is built with the highest quality components and undergoes rigorous testing to meet industry standards. You can have peace of mind knowing that your battery is protected by our reliable and intelligent system.

In conclusion, our advanced BMS with passive current limiting is a game-changer in the world of battery management. By incorporating cutting-edge technology and customizable features, this product guarantees a safe and optimized charging experience for your battery. Upgrade to our BMS today and safeguard your battery against overcurrent and potential damage, while prolonging its overall lifespan.
