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

Our Battery Balancing System is designed to tackle the challenge of unbalanced cells during both charging and standby periods. By efficiently balancing the cells, our system ensures optimal performance and significantly improves the overall service time and cycle life of the battery.

One of the key features of our Battery Balancing System is its ability to be controlled and adjusted through an upper computer. This means that the balanced opening voltage and balanced differential pressure can be conveniently set according to specific requirements. This flexibility enables users to fine-tune the balancing process, ensuring maximum efficiency and longer-lasting batteries.

The advantages of our Battery Balancing System are truly remarkable. Not only does it rectify existing unbalanced cell issues, but it also prevents future imbalances from occurring. This proactive approach not only saves time and money but also minimizes the frustration of dealing with unreliable batteries.

Moreover, our Battery Balancing System is engineered with the utmost consideration for safety. It is designed to effectively handle high voltages and sustained use, ensuring a reliable and secure operation. This level of safety is crucial, especially in applications where batteries are subjected to prolonged charging or heavy use.

In conclusion, our battery balancing system is a necessary feature in the battery industry. With its ability to balance the battery during charging or standby, it ensures longer service life and longer cycle life. Adjusting the settings through the upper computer increases convenience, allowing users to customize the balancing process to meet specific requirements.

(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. Passive current limiting: In the charging state, if the charging current reaches the charging overcurrent alarm value, the BMS will turn on the 10A current limiting function, and re-check whether the charger current reaches the passive current limiting condition after 5 minutes of current limiting. (Open passive current limit value can be set).
