Abstract
The invention discloses a battery charging method for an electric automobile. When a storage battery pack is connected to charging station equipment and a loop switch is in an off state, a battery management unit of a battery sensing device of the electric automobile reports attribute data of the storage battery pack to the charging station equipment through a CAN (controller area network) bus or a wireless communication mode. According to the battery charging method, each storage battery unit and an intelligent monitoring unit are taken as nodes in a sensor network by virtue of a sensor network technology; the battery management unit becomes a convergent node; the charging station equipment which is connected with the battery sensing device of the electric automobile can be used as a gateway node, so that seamless connection with external networks such as power distribution networks, internet of vehicles and internet of roads is achieved.
Description
Technical field

Background technology
Along with the development of the correlation technique of electric automobile, electric automobile has entered in popular work and life gradually.And in the correlation technique of electric automobile, the battery as the electric automobile of energy supplier is most important.
In the battery of existing electric automobile in be provided with battery management system (Battery Management System, be called for short BMS).BMS has the function of data acquisition, utilizes the data collected make rationally effective management to battery and control.For lithium ion battery, because the security requirement of this battery is high, to voltage-sensitive, allly need the voltage gathering each cell, monitor the temperature of each battery.
BMS also has multiple functions such as electrical control, safety management control, battery temperature management and data communication.But existing BMS cannot carry out safety to battery and identify and false proof management.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of charging batteries of electric automobile method.
Technical scheme of the present invention is: a kind of charging batteries of electric automobile method, when batteries is connected to charging station equipment, and circuit switching is when being in off-state, the battery management unit of batteries of electric automobile sensing device reports the attribute data of described batteries by CAN or communication to described charging station equipment;
Described charging station equipment adjusts charging voltage to battery open circuit voltage according to the attribute data of the described batteries received, and orders described battery management unit to connect described circuit switching;
Described charging station equipment steadily increases charging voltage, until charging current reaches preset value;
In charging process, described battery management unit calculates charge volume in real time, notifies described charging station equipment adjustment charging current according to described charge volume.
Preferably, the current voltage of intelligent monitoring unit to the secondary battery unit of self correspondence of described batteries of electric automobile sensing device is monitored, and calculates corresponding dynamically internal charging resistance;
The temperature of described intelligent monitoring unit to described secondary battery unit detects in real time;
Described dynamic internal charging resistance and/or temperature are reported described battery management unit by described intelligent monitoring unit, judge that described secondary battery unit is the need of balancing energy by described battery management unit, if receive the equalization command that described battery management unit sends, then by output voltage and the output current of the electric adjusting power restricted type voltage boosting dc/direct current transducer of setting, dump energy is converted to the rechargeable energy of standby battery group, or dump energy is returned to described charging station equipment.
Beneficial effect of the present invention: the present invention adopts sensor network technique using each secondary battery unit and intelligent monitoring unit as the node in sensor network, battery management unit becomes aggregation node, the charging station equipment be connected with batteries of electric automobile sensing device can as gateway node, thus network with power distribution network, car, the external network such as road networking realizes seamless link; For batteries of electric automobile sensing device self, battery management unit can to batteries carry out overall attribute obtain and and PERCOM peripheral communication, and each secondary battery unit also carries out Real-Time Monitoring and control by each self-corresponding intelligent monitoring unit respectively, so just achieve the intelligent management function of batteries of electric automobile more comprehensively.
