DTC Conditions
200
Battery charging
overcurrent fault
Disconnect the relay, and cut off the
battery charging circuit
The battery charging current is greater than
69.5 A and lasts 5s
201
Battery discharging
overcurrent fault
VCU notifies MCU to limit current by 30%.
When a serious overcurrent fault occurs,
the user should stop the motorcycle nearby
and turn it off until this fault is resolved.
The battery discharge output current is too
large (moderate overcurrent fault if the current
is >156.6 A for 5S continuously, and serious
overcurrent fault if the current is >174 A for 1S)
202 Battery undervoltage fault Disconnect the discharging circuit
The battery voltage is too low, and the
single cell voltage is below 2.7 V (if the
undervoltage is less than 2.5 V, the cell will
be severely damaged, and the battery pack
will be locked and can only be recovered
through the host computer)
210 Controller overcurrent fault The controller is turned off
When the actual output current is > 630 A/
the controller is damaged
211 Controller overvoltage fault The controller is turned off
The input voltage of the controller bus
exceeds the permitted range (>115 V)
212 Motor Hall fault The controller is turned off
The feedback signal of the motor position
sensor is abnormal
213
Speed-control turning
handle fault
After a fault occurs, VCU shields
the turning handle control, and the
motorcycle will continue to glide
When the power supply voltage of the turning
handle is ≠ 5V, the resistor in the VCU turning
handle circuit will become ineffective
203
Battery discharging
overheating fault
VCU notifies MCU to limit current
by 30%. The user should stop the
motorcycle nearby and turn it off until
this fault is resolved.
The battery temperature is higher than
55°C
204
Battery discharging low-
temperature protection
VCU notifies MCU to limit current
by 30%. The user should stop the
motorcycle nearby and turn it off until
this fault is resolved.
The battery temperature is lower than
-20°C
205
The temperature of the
battery pack exceeds the
permitted measurement
range
VCU notifies MCU to limit current
by 30%. The user should stop the
motorcycle nearby and turn it off until
this fault is resolved.
Invalid temperature measurement
206
Switch temperature fault
involving the battery pack
MOS tube
VCU notifies MCU to limit current
by 30%. The user should stop the
motorcycle nearby and turn it off until
this fault is resolved.
The battery pack MOS temperature is
higher than 85°C
214
Controller over-
temperature fault
The controller is turned off Controller overheating (>100°C)
215 Motor over-temperature fault The controller is turned off Motor overheating (>135°C)
207
Battery pack
communication fault
During the operation, the fault is
reported to VCU without power cut-off.
If this fault occurs during the power-
on process, the power-on operation
cannot be carried out normally.
1. Battery internal communication fault: the
single cell voltage data and temperature
data are lost.
2. Battery and VCU communication fault
216
Controller communication
fault
The controller is turned off
MCU-VCU communication timeout (50ms
without any VCU command received)
217
The controller temperature
sensor exceeds the
specified range
The controller is turned off
The sensor experiences an open circuit or
short circuit/the ambient temperature of the
controller is abnormal
208
The insulation resistance
is too low
Report this case to VCU with record
made
If the insulation resistance is ≤ 100Ω/V,
and a fault occurs before power-on, the
battery pack relay will not engage, so the
motorcycle cannot be ridden. If a fault
occurs after power-on, the relay cannot be
disconnected as it has been engaged
