Brief description of the drawings
Fig. 1 is that the utility model power battery management system signal transmits schematic diagram.
Fig. 2 is the utility model power battery management system circuit connection diagram.
Embodiment
Further detailed is made to the utility model and its advantage below in conjunction with embodiment and Figure of description
Describe in detail bright, still, embodiment of the present utility model is not limited thereto.
As illustrated in fig. 1 and 2, power battery management system, including battery management unit, smoke alarm, vehicle alarm,
Vehicle administrative unit, signal conversion unit, Battery case and battery, the battery management unit and the smoke alarm
Be arranged in the Battery case, the vehicle administrative unit respectively with battery management unit, vehicle alarm and battery
Electrical connection, the signal conversion unit is electrically connected with battery management unit, vehicle administrative unit and smoke alarm respectively, described
Signal conversion unit can determine that the running status of battery management unit, and select described in battery management unit power-down state
Battery is as power supply, to be powered to smoke alarm, makes to still ensure that under battery management unit power-down state
Electrokinetic cell is monitored, improved using safety.
Wherein, battery management unit is responsible for driving with vehicle communication, diagnosis, demarcation, high-voltage relay, calculates battery SOC
And SOH, management battery status and application strategy.
Vehicle alarm is received after alarm signal, is touched alarm speaker, is played warning function.
Vehicle administrative unit is responsible for receiving battery management unit fault message, manages vehicle alarm, is the brain of vehicle.
Signal conversion unit is responsible for monitoring the state of vehicle, judges that battery management unit is in running status or lower electric shape
State, battery management unit in running status by battery management unit as power supply, when battery management unit does not work by
Direct battery power, it is ensured that smoke alarm remains to normal work.
Specifically, this power battery management system is included in electric and lower electric both of which (battery management list in vehicle low pressure
First running status or and power-down state), once in the case that there is leakage or smoldered in battery, and alarm；
1) (battery management unit works power battery management system, in vehicle low pressure during electric automobile is run
Electricity), once occur that battery system leakage or a variety of causes cause in Battery case smolders, smoke alarm feeds back to signal
Signal conversion unit, signal conversion unit is sent to battery management unit, and it is single to feed back to vehicle management by battery management unit
Member, the power output of vehicle administrative unit controlled motor controller, while sending alarm signal gives vehicle alarm, vehicle triggering
Alarm；
2) battery car is in the case of stop, now (battery management unit does not work, electric under vehicle low pressure), vehicle pipe
Reason unit detects battery management unit and is stopped, and opens and enables signal, is switched to power mode under battery management unit, now
