Furthermore, the power management system comprises a battery power monitoring unit and a control unit, wherein the battery power monitoring unit is used for monitoring the real-time power of the lithium battery, and the control unit is used for controlling the electrification and the outage of the plurality of power utilization systems.
Further, the control unit is a high performance computer.
Further, the powered system includes a vehicle security system, a vehicle start-up system, and a vehicle entertainment system.
Furthermore, the device also comprises an alarm connected with the power management system, and the alarm is used for giving an alarm to a driver when the power generation system cannot generate power normally.
Furthermore, the alarm is an audible and visual alarm.
The utility model also provides an electric vehicle, it has included above-mentioned content electric vehicle power management system.
The utility model has the advantages of it is following:
1. when the lithium battery discharges, the safety system can be preferentially supplied with power through the controller according to the residual electric quantity of the battery, then the starting system is supplied with power, and then the entertainment system is supplied with power, so that the discharging management of the lithium battery is optimized;
2. when the power consumption information monitoring unit monitors that the vehicle is parked for a long time, and the electric quantity of the lithium battery is lower than a safety value, the power supply management system cuts off all output of the battery, and the power supply management system needs to be manually restarted to restart the vehicle, so that the safety is improved;
3. when the vehicle is normally started, when the electricity information monitoring unit monitors that the vehicle power generation system normally generates electricity, the power management system can carry out charging management on the battery according to the actual electric quantity of the battery, when the electric quantity of the battery is charged to 100%, the power management system turns off the battery for charging, and at the moment, the power supply of the whole vehicle is provided by the vehicle power generation system; when the electricity information monitoring unit monitors that the vehicle power generation system can not generate electricity normally, the power management system sends out warning to the driver through the alarm to remind the driver to check the vehicle in time, so that the safety is greatly improved, and the service life is prolonged.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
As shown in FIG. 1, an electric vehicle power management system includes
The system comprises a lithium battery, a power management system and a power utilization information monitoring unit;
the power supply management system is used for charging management and discharging management of the lithium battery;
the power consumption information monitoring unit is connected with the power consumption systems and used for acquiring the running state information of the power consumption systems and the vehicle power generation system and transmitting the running state information to the power management system.
The power management system comprises a battery power monitoring unit and a control unit, wherein the battery power monitoring unit is used for monitoring the real-time power of the lithium battery, and the control unit is used for controlling the electrification and the outage of a plurality of power utilization systems.
The control unit is a high-performance computer.
The power utilization system includes a vehicle security system, a vehicle start system, and a vehicle entertainment system.
The power generation system is connected with the power management system, and is used for giving an alarm to a driver when the power generation system cannot generate power normally.
The alarm is an audible and visual alarm.
The utility model also provides an electric vehicle, it has included above-mentioned content electric vehicle power management system.
The working process of the utility model is as follows: when the vehicle is normally started, when the electricity utilization information monitoring unit monitors that the vehicle power generation system normally generates electricity, when the electric quantity of a lithium battery is lower than a set value (for example, lower than 30%), the battery is charged and managed, when the electric quantity of the battery is charged to 100%, the power management system cuts off the battery charging, and at the moment, the power supply of the whole vehicle is provided by the vehicle power generation system; when the power consumption information monitoring unit monitors that the vehicle power generation system can not generate power normally, the power management system sends out warning to the driver through the audible and visual alarm to remind the driver to check the vehicle in time.
When the lithium battery discharges, the safety system can be preferentially supplied with power through the controller according to the residual electric quantity of the battery, then the starting system is supplied with power, and then the entertainment system is supplied with power.
When the power consumption information monitoring unit monitors that the vehicle is parked for a long time, so that the electric quantity of the lithium battery is lower than a set safety value (for example, lower than 30%), the power supply management system cuts off all the output of the battery, and at this time, the power supply management system needs to be manually restarted, so that the vehicle can be restarted.
