Short circuit protection at the battery terminal of all sampling lines to prevent short circuit between  batteries caused by sampling lines

Adopt advanced power consumption reduction technology to prolong the battery working time

Suitable for the management and protection of energy storage and backup LiFePo4 battery pack, LiMn2O4 battery pack and LiCoMnNiO2 battery pack


Details
HL-S48 is a leading lithium battery management system, which is mainly used in the unified management of multiple lithium serial and parallel packs, and supports remote monitoring. When the voltage, current, temperature overrun of the battery or the whole group of short circuit reverse connection, the system will send out the related signals to the PCS and EMS systems, which cut off the circuit to protect the battery from damage. In the process of battery charging or floating, the system can balance the energy difference of different battery effectively by the intelligent on-line battery equalization technology to achieve the maximum group storage capacity. HL-S48 has also adopted the estimation technology with autonomous learning function, which is unique to Huasu company, predicting the SOC and SOH more accurately. 


Specification
SOC&SOH Monitoring
The built-in mathematical model for estimating the residual capacity is provided with a self-learning function, can automatically correct the estimation model according to different application environments and load current, and accurately predicting the effective loading time of the battery and also the battery health state.

Intelligent Online Battery Equalization
The battery power can be automatically balanced during the charging or floating charging process which effectively prolong the battery loading time.

Application
The energy storage lithium battery pack

Operation Parameters and Alarm Setting
The alarm threshold, system operating parameters, protection thresholds, and monitoring data can be set locally, with authorization password protection.

Local Data Storage

FAQ
Q1. Why monitoring battery internal Resistance?
A: Generally, we confirm the battery situation through discharging of the battery. With this handling, we can work on the real capacity but it is very time-consuming. After doing reasearchs, we find the internal resistance of the battery will be increased that due to various causes of capacity decline. If we regularly monitor the internal resistance of the battery and compare it with the initial internal resistance, it will be easy to detect the performance change of the battery and also find out the problem battery. 

Q2. Why monitoring battery temperature?
A: Battery temperature is like human body temperature, when there is a problem with the battery internal temperature will tend to rise, generally like the battery internal part of short circuit, charging voltage is too high will cause temperature rise. Therefore, the problem of battery pack can be detected as early as possible by monitoring the temperature inside the cell.

Q3. Can your products be discharged remotely?
A: Yes, the control unit can be controlled remotely, and the capacity unit can be controlled by the control unit to discharge the battery. But when discharging, the battery pack needs to be operated manually or other control methods to separate from the power supply system. We have done the whole system including the charger by technology project of remote control, but this method is not promotion, mainly is the present charger stability DC screen is not enough, manufacturers can not guarantee the safety and effectiveness of the remote control function, easily lead to loss of control. At present, the technology of remote discharge products in the market is not mature, as a pilot can, it is not suitable to promote, it is recommended that users do not use this product at present.

Q4. Do your products have the balance function?
A: Yes. We take the method of shallow charge & discharge for the battery to the battery voltage balance section.

Q5. How does the product solve the line interference and the environmental interference ?
A: We have considered various interference conditions during the design , and special EMC is processing on the circuit which can meet the requirements specified in UL and DL / T856 - 2004 , and we have corresponding EMC test reports.

Q6. The equipment can access to the third party system? How to access?
A: Yes. It is very easily access to your third party system. Generally, you only take one or two days to put programs.H3G system comes with a special serial port for the use of third party system, support the MODBUS protocol. The specific access method and communication protocol can be provided by our customer service department.
