S3. it after stopping load output, finishes to troubleshooting, is restarted at this time by key switch, control system detection is whole
Hair powers on instruction to battery management system after machine fault-free, and battery management system controls the main contactor in lithium battery and is attracted.
In step S1, battery management system sends information to control system by CAN bus, and control system reception is made
Corresponding control.
In step S1, the setting of failure sorted is according to the parameters of different aerial lift devices and lithium battery, in conjunction with reality
Working condition is configured, and is at least divided into two-stage, and respectively generic failure (limitation load) and catastrophe failure (stops load, stops
Only lithium battery discharges).
In step S2, according to different aerial lift devices, its load is not also identical for load, such as scissor-type high-altitude operation vehicle,
Generally it is made of chassis, scissor yoke, workbench, hydraulic system, electrical system.Main controller controls electric machine controller, electricity
Machine controller controls unlatching and the revolving speed of motor, motor-driven hydraulic pumps rotation, and hydraulic pump provides hydraulic energy to hydraulic system,
The on-off of hydraulic valve in main controller controls hydraulic system loads the just hydraulic valve including hydraulic system, the electricity in electrical system
Machine controller, motor etc..
In step S2, it is specific as follows that control system obtains lithium battery fault message:
Battery management system sent in real time according to some cycles lithium battery total voltage, monomer voltage and temperature, discharge current,
SOC, SOH, main contactor state, battery management system fault message etc., for general parameter information, after control system receives
It is dealt into display screen to show, user can be inquired by the key on display screen, lithium battery state be controlled in real time convenient for user, when lithium electricity

It needs, takes the control method for reducing lifting power (60~80%)；Battery SOC is in 5% to 10% section, and electricity is obviously not
Foot preferential walking motion and can only be forbidden lifting, be moved to it smoothly at charging socket and charge；When battery SOC is less than 5%,
In order to protect battery, power output should be cut off, stops battery discharge.
For monomer temperature and discharge current, failure can be divided into two-stage, respectively the first preset value and second are preset
Value, when monomer temperature or discharge current limit the output (generic failure) of load between the first preset value and the second preset value,
More than or equal to the output (catastrophe failure) that the second preset value stops load.
Wherein by taking monomer temperature as an example, aerial lift device is scissor aerial work platform, and the first of monomer temperature is pre-
If value is 55~60 DEG C, the second preset value is 60~65 DEG C, and the output power for limiting load is the 60~80% of maximum power.
