Remote Data Center Intelligent Online Monitoring Internal Resistance Battery Management System

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 some research, 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. 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.

Q5. 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.
