Accompanying drawing explanation
The content expressed every width accompanying drawing in description of the invention below is briefly described:
Fig. 1 is cell management system of electric automobile block diagram.
Detailed description of the invention
The present invention is when system electrification, and BMS can control pre-charge system work, prevents instantaneous large-current from impacting；By reality
Time monitoring electrokinetic cell state, communicate with electric machine controller, entire car controller, charger.At vehicle operation
In, vehicle can be run necessary data and send to electric machine controller by BMS；During battery trickle charge, BMS can realize filling with vehicle-mounted
Communication between electricity equipment；During battery fills soon, BMS can realize the communication between fast fill device so that charger
The current state of battery can be fully understood by, it is ensured that the safety of charging.BMS can be according to the abnormality of set of cells by fault seriousness
Dividing two grades to report to the police to car load, in the case of secondary alarm, electric machine controller should drop according to available charging and discharging currents value
Power operation；Under one-level alarm condition, should stop battery being carried out discharge and recharge.
Concrete control method:
1, charging strategy:
On charging plug, CC signal (charging connection confirmation) is received by BMS.
When entire car controller is in park mode: BMS powers on and wakes up up, receives CC and confirm charged state, and closed by BMS
Closing always to bear relay (gross vehicle load-relay) and send message and wake up entire car controller up, entire car controller enters charging mould
Formula, and control closed DC/DC relay (relay of commutator transformer on charging circuit), send charging connection and charged state
Message is to instrument, by instrument (the display instrument on instrumental panel and/or charger in car) display charging connection and charged state.
Entire car controller is in and powers on or during driving model: BMS sends charge information message to entire car controller, car load control
Device processed exits driving model or power up mode, enters park mode and disconnects all high voltage electric devices and (set as required
Determine corresponding electric appliance, such as air-conditioning, blower fan, headlight etc.), then entered charge mode by park mode, and control closed DC/DC relay
Device (relay of commutator transformer on charging circuit), transmission charging connection and charged state message are to instrument, by instrument (in car
Display instrument on instrumental panel and/or charger) show charging connection and charged state.
Having only to charging connection confirm, BMS sends charged state, and entire car controller can not enter driving model.
Real-time communication set up by BMS and charger, and in charging process, BMS is responsible for detection each battery module voltages, temperature in real time
Degree and charging current, forbid charging as battery temperature ＞ 45 DEG C.In charging process, when any battery module voltage exceedes
During 4.2V, BMS sends signalisation charger and stops charging, and block system relay, response time requirement≤1 second.Monomer mistake
Pressure, total voltage is too high, temperature too high response secondary failure is reported to the police, and machine response to be charged processes, and the most untreated is persistently upgraded to
Time delay 3S after level fault, directly cuts off main relay.
2, discharge control method:
When key is in ACC or ON shelves, BMS powers on and wakes up up, wakes up rear BMS up and receives the battery enable that VCU sends
Signal, the total negative relay in BMS Guan Bi battery case.Battery case built-in electrical insulation detection module is started working, and sends system insulation
By BMS, resistance value, to BMS, judges whether high tension loop exists Insulation Problems, then disconnect total negative relay if any Insulation Problems.
BMS gathers battery temperature, voltage, electric current, SOC value, insulation resistance and the content such as state of insulation, fault message and is sent to car load control
Device processed, it is judged that running status and defect content, and shown malfunction and SOC value etc. by instrument.
During monomer is under-voltage, temperature is too low, stagnation pressure is under-voltage secondary alarm, persistently send alarm failure and wait at car load response
Reason, the most untreated lasts till time delay 3S after level fault, directly cuts off main relay.
3, safety protection control method:
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by aforesaid way
Restriction, as long as have employed the method design of the present invention and the improvement of various unsubstantialities that technical scheme is carried out, or without changing
Enter and design and the technical scheme of the present invention are directly applied to other occasion, all within protection scope of the present invention.
