Description
Technical field
The present invention relates to vehicle charging system technical fields, and in particular to a kind of electric bus charging safeguard protection
System.
Background technique
Electric vehicle power supply unit (EVSE) system can be configured to convenient for high pressure (HV) battery or by electronic friendship
Other energy that logical tool (EV), the hybrid electrically vehicles (HEV) and the plug-in type hybrid electrically vehicles (PHEV) use
Memory element charging is measured, to support various vehicle operations.EVSE may need to refer to the traffic work of voltage or the vehicles
Tool charging system prepares other instructions for receiving energy from EVSE.Vehicle charging system prepares to receive from EVSE in order to prevent
The error indication of energy exists when vehicle charging system does not prepare to receive energy --- it is included in vehicles Charging
During the case where controller or other elements of system may incorrectly operate --- ensure the needs that EVSE is informed to.
Summary of the invention
The purpose of the present invention is overcoming existing electric bus during the charging process, since maloperation or control unit go out
Existing failure causes electric bus to be caused danger suddenly movement, and there are the deficiencies of security risk, and providing a kind of there is charging to pacify
The bus charging system and method for all risk insurance protective function.
To achieve the above object, the present invention provides it is a kind of with charging safety protection function bus charging system,
The charging system includes: a kind of electric bus charging safety system, including charger, power battery, battery management
Device, battery relay and control unit, are characterized in that, further include be arranged between charger and battery manager
Two communication buses, and the first communication bus being arranged between battery manager and control unit；The charger passes through institute
It states the second communication bus and sends power battery status information to the battery manager；The battery manager receives the battery
Status information, and battery relay is controlled according to the battery status information and disconnects and is closed, to control electric motor of automobile and institute
State the electrical connection of power battery；The battery manager receives the battery status information, and according to the battery status information,
Forbid instructing to described control unit transmission by the first communication bus；Described control unit receive it is described after forbidding instruction,
Any control command is no longer exported outward.
Further, above-mentioned control unit is entire car controller and/or All-in-One controller and/or shift handle.
Further, above-mentioned first communication bus and the second communication bus are CAN communication buses.
Further, above-mentioned CAN communication bus includes CANH bus and CANL bus.
The invention has the advantages that charging system provided by the invention and method are passed through by the control mode of software and hardware
Control relay switch and control unit forbid sending the mode of control command；It ensure that in charging process, electric bus exists
Will not all cause danger movement when maloperation or control unit failure, guarantee whole public transport when to effectively realizing charging
The purpose of vehicle safety.
Detailed description of the invention
In order to facilitate the understanding of those skilled in the art, the present invention will be further described below with reference to the drawings.
Fig. 1 is the structural schematic diagram of one embodiment of the invention；
Heavy line with the arrow is power line in figure, and fine line with the arrow is communication line.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
A kind of electric bus charging safety system as shown in Figure 1, including charger, power battery, cell tube
Manage device, battery relay, control unit, the second communication bus being arranged between charger and battery manager, and setting
The first communication bus between battery manager and control unit；Control unit be entire car controller, All-in-One controller and
Shift handle.First communication bus and the second communication bus are CAN communication buses；CAN communication bus include CANH bus and
CANL bus.As shown in Figure 1, the first communication bus is the special communication bus of full-vehicle control；First communication bus is denoted as CAN1,
Its two buses are denoted as CAN1H and CAN1L respectively；It is communicated between charger and battery manager when second communication bus is charging
Special circuit, the second communication bus is denoted as CAN2, and two buses are denoted as CAN2H and CAN2L respectively.Charger passes through second
Communication bus sends power battery status information to battery manager.Battery manager receives battery status information, and according to electricity
Pond status information controls battery relay and disconnects and closure, to control being electrically connected for electric motor of automobile and power battery；Cutting is dynamic
Power battery High voltage output cuts off the high voltage power source of vehicle, with reach any maloperation in vehicle charging will not cause it is whole
The purpose that vehicle is started to walk suddenly, accelerated.Battery manager receives battery status information, and according to battery status information, passes through first
Communication bus is forbidden instructing to control unit transmission；Control unit receives forbid instruction after, no longer export any control outward
Order.
The working method of electric bus charging safety system, including the following steps: step 1, battery manager are logical
It crosses and its second communication bus between charger is set, receive the status information of the power battery of charger transmission；Step
If 2, power battery is charged state, battery manager controls battery relay and disconnects, and cuts off electric motor of automobile and power battery
Electrical connection；At the same time, battery manager by setting itself and entire car controller, All-in-One controller and shift handle it
Between the first communication bus, to entire car controller, All-in-One controller and shift handle transmission forbid instructing；Entire car controller,
All-in-One controller and shift handle receive forbid instruction after, no longer export any control command outward.
