2.2 Charger function introduction
2.2.1 HMI
1 Charge setting method:
Can choose automatic setting mode and manual setting mode.
a) Automatic setting means charging is performed according to the status and command of
battery BMS.
b) Manual setting means charging is carried out on the basis of credit, electricity energy, power,
etc. Guidance information can be found on HMI.
2
)
Display
a) Real-time display of charging voltage, charging current, SOC, charging time, billing, battery
information and other information.
b) Manual input is displayed during manual setting.
c) In the event of a fault, the corresponding message is displayed.
d) Corresponding information of different running status can be shown on HMI.
e) Can display battery information.
2.2.2 Parameter setting
operator enters the setting interface through the password and sets the parameters of over /
under voltage protection threshold, overcurrent protection threshold, IP, communication port.
etc.
2.2.3 Self test
1) Charger self-test when powering on, including charger status, real time clock, power, etc.
2) Fault information is indicated via indicator light and display, which is also recorded in the HMI
as history fault data.
2.2.4 Firmware update
Support remote and local software upgrade functions when there is master station monitoring
system, and support local upgrade function when there is no master station monitoring system.
2.2.5 Data transmission and storage
a) Transmission
The charger has data transmission interface to collect and upload charging information data as
well as charger fault data.
