Lead-Acid Battery Management System
1 System Overview
GM Series Electric Vehicle Battery Management System is our latest
manufacturers specifically for electric vehicles and electric
vehicle battery manufacturers tailor-made high-end technology
solutions. The system is suitable for electric vehicle batteries (lead acid /
lithium iron phosphate battery) monomer and the whole group of
real-time monitoring, charging and discharging, inspection,
voltage, temperature monitoring, using the remaining battery power,
such as estimates, over-temperature protection cutting-edge intelligent technology, termed the field of domestic
battery detection of the most powerful, technical indicators are
most complete intelligent management of battery power detection
system.

2 System Function Description
Battery remaining capacity prediction: real-time charging and
discharging process, can be on-line monitoring remaining capacity
of each cell can be real-time estimates of the remaining battery
capacity according to battery capacity and vehicle operating
conditions predict remaining battery continued line mileage.
Voltage, temperature monitoring: real-time monitoring of each cell
voltage and temperature.
Overcurrent, overvoltage, over temperature alarm and protection: in
batteries (including the system as a whole and the single-cell)
occurred overvoltage, undervoltage and over-temperature, they can
send alarm signal. In the charging process of filling, in case of over-voltage,
over-temperature conditions can be adjusted charge mode, or even
cut off the charger to prevent battery damage occurs, or fire,
explosions and so on.
With the Vehicle Communication: The CAN bus ways and vehicle
management systems to communicate, through the display shows
real-time vehicle operation information, according to vehicle
operating conditions and battery capacity, remaining capacity
predict remaining battery mileage, so that users can readily know the life electric vehicle mileage, and identify appropriate
opportunities for charging, to avoid the halfway anchored to
happen.
Power-down to save: Vehicle running mileage, the remaining battery
power, the system parameters can be powered down to save, to
prevent data loss due to power-down to happen.
Fault recording and storage, data output: The battery life process,
the time record and display the battery type and time of the fault
occurred, as well as poor performance, battery location, you can
also extract data via USB interface, as a basis for battery
maintenance and replacement.
Charge control: intelligent control of the battery charger
charging, the battery during charging to prevent over-voltage and
over-temperature, to ensure that under the premise that security is
guaranteed, every single battery is fully charged, which can slow
the progress of aging batteries, extending battery life.
System combination is very flexible, you can choose a management
option by showing Ping battery type, battery pack includes battery
capacity and number of monomers.
Display Function: The system console from the color touch-screen
and management of computer composition, you can display real-time
vehicle operating information, battery packs and the single cell
information, charging machine status information, and other
functional modules of information.
2.2 Module Function
Battery Monitoring Module: In the battery charging status,
discharge status, as well as idle, real-time monitoring of battery
voltage, temperature and remaining capacity, and through CAN
communication transmitted to the LCD mete
