The software function
System settings: the alarm to accept a person, discharge planning and communication server detailed settings, and alarm definition, diagnosis results, state state resistance loop state, charger, battery string state state.
Setup function: the realization of the master station, sub station is set up, and the remote monitoring equipment, battery charger (battery), set the parameters of the battery string.
User management functions: user divides into five levels: the system administrator, the administrator, the master station, sub station operators administrator, sub station operators, the functions of each user to add, delete and modify.
User management functions: user divides into five levels: the system administrator, the administrator, the master station, sub station operators administrator, sub station operators, the functions of each user to add, delete and modify.
Alarm function: it can sound and light, EMAIL, short messages, the time for your prompt alarm information. When the battery failure or to the activation of the battery to discharge, the system will automatically prompts the user, the user in the prompt guidance to handle the event.
Can display real-time state of battery battery string and discharge power supply time according to the current load.
Equipment monitoring function: to achieve time synchronization equipment monitoring, discharge application, check, internal resistance measurement, voltage measurement, battery charger, diagnosis, record voltage recording data acquisition control box.
The data processing function: the data analysis of data in a single cell or whole group form, get the data table and icon, the charging and discharging process of playback, and detailed analysis and processing of alarm information. Receiving the current and historical records, voltage resistance record and alarm event records from the monitoring equipment.
Analysis of received data recording, display graph, table, the trend line.
To alert the user to a specific event.
Generate analysis report.

Safety index
Safety index system conforms to the GB4793-84 standard.
Series battery monitoring system is designed to give full consideration to the various situations and accidents on the system itself and the system of all kinds of equipment supporting the use of impact, the more impact zero export high fault tolerance method, detection equipment all uses high performance components, the system has the characteristics of high safety monitoring system with self checking function. Independent operation abil. Independent operation ability is very good, is not affected by the working condition of the user's system, also do not affect the user system, internal resistance measurement only in battery group in the state of floating charge of. Although the discharge current is high, but because the discharge is the discharge circuit in the battery pack with high power and low resistance for 6 battery and device in a just a few seconds, discharge, and the device itself is a good heat dissipation and Ge Yu measures (high power low resistance discharge resistance with special heat sink, fan, each discharge loop line fuse resistance measurement device, module and other modules with even isolation etc.), so the resistance measurement is safe, will not affect the battery safe operation of the power supply system of series battery monitoring system fully consider the characteristics of electromagnetic compatible in the circuit design and structure design, electromagnetic radiation the amount is less than the national standard, has the shielding effect is very good, the system itself to the outside world without any electromagnetic interference.
