Battery condition is provided, picks out problematic battery, battery bag reliability of operation and high efficiency is kept, assesses dump energy
Model is implemented as possibility.
Electric after the startup of electronic railway carriage or compartment lorry, while in battery bag control system (BCS), BCS can control pre-charge system work
Make, prevent instantaneous large-current from impacting；By monitoring the working condition of electrokinetic cell bag in real time, with electric machine controller, full-vehicle control
Device, charging equipment are communicated.In vehicle operation, vehicle can be run necessary data and be sent to electric machine controller by BCS；
During battery bag trickle charge, BCS can realize the communication between vehicle-mounted charging equipment；During battery fast charge, BCS can be real
The now communication between fast fill device so that charging equipment can be fully understood by the current state of battery, ensure the safety of charging.
BCS can be alarmed according to the operation irregularity state of battery bag by failure seriousness point two level to vehicle, in secondary alarm situation
Under, electric machine controller should be according to can carry out downrating with charging and discharging currents value；Under one-level alarm condition, it should stop to battery
Carry out discharge and recharge.
First, charging strategy：
1. CC signals (charging connection confirmation) are received by BCS on charging plug.
2. entire car controller is in park mode：The upper electricity of BCS wakes up, and receives CC and confirms charged state, and by BCS
Closure, which always bears relay and sends message, wakes up entire car controller, and entire car controller enters charge mode, and controls closed DC/DC
Relay, charging connection and charged state message are sent to instrument, charging connection and charged state are shown by instrument.
3. entire car controller is in upper electricity or driving model：BCS sends charge information message to entire car controller, vehicle
Controller exits driving model or power up mode, into park mode and all high voltage electric devices is disconnected, then by dormancy mould
Formula enters charge mode, and controls closed DC/DC relays, charging connection and charged state message is sent to instrument, by instrument
Show charging connection and charged state.
4. needing charging connection to confirm, BCS sends charged state, and entire car controller can not enter driving model.
5.BCS and charging equipment establish real-time communication, in charging process BCS be responsible for detecting in real time each battery module voltages,
Temperature and charging current, forbid charging as 45 DEG C of battery temperature ＞.In charging process, when any battery module voltage exceedes
During 4.2V, BCS sends signal notice charging equipment and stops charging, and block system relay, response time requirement≤1 second.Monomer mistake
Pressure, total voltage are too high, the too high response secondary failure alarm of temperature, and machine response processing to be charged is untreated always to be persistently upgraded to
Be delayed 3S after level fault, directly cuts off main relay.
2nd, electric discharge strategy：
1st, when car key is in ACC or ON gears, the upper electricity of BCS wakes up；
2nd, BCS receives the battery enable signal of VCU transmissions after waking up, and BCS closes the always negative relay in battery case.
3rd, battery case built-in electrical insulation detection module is started working, and is sent system insulating resistance value to BCS, is judged by BCS high
Push back road and whether there is Insulation Problems, always negative relay is then disconnected if any Insulation Problems.
4th, BCS gathers the content hair such as battery temperature, voltage, electric current, SOC value, insulaion resistance and state of insulation, fault message
Entire car controller is given, judges running status and defect content, and malfunction and SOC value etc. are shown by instrument.
During the 5th, monomer is under-voltage, temperature is too low, stagnation pressure is under-voltage secondary alarm, persistently send alarm failure and wait at vehicle response
Reason, it is untreated always to continue to the 3S that is delayed after level fault, directly cut off main relay.
3rd, safeguard protection parameter and corresponding strategies：
The present invention is exemplarily described above, it is clear that present invention specific implementation is not subject to the restrictions described above,
As long as employing the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress, or not improved this is sent out
Bright design and technical scheme directly applies to other occasions, within protection scope of the present invention.The protection of the present invention
Scope should be determined by the scope of protection defined in the claims.
