When the mobile terminal 004 is used, a vehicle owner can watch the current electric quantity of the battery of the vehicle through the mobile terminal 004, the mobile terminal 004 can be a mobile phone device of a householder and the like, when the monitoring module 003 monitors that the electric quantity of the battery is in low electric quantity, a signal is sent to the monitoring module 001, the monitoring module 001 forms an instruction and sends the instruction to the mobile terminal 004, an alarm prompting unit is arranged on the interface of the mobile terminal 004 for alarming, the alarm prompting unit can be a short message notice or a horn-shaped prompting signal flashing on the interface of the mobile terminal 004, and when the battery alarms in low electric quantity, a user needs to arrange charging before using so as to avoid the possibility of power failure of the vehicle in the driving process. When the monitoring module 003 monitors that the electric quantity of the battery is in the middle electric quantity, the user needs to properly schedule the driving distance when using the battery, and when the distance where the user needs to drive is long, the user also needs to schedule the charging time in advance. Similarly, the battery temperature of the electric vehicle has a great influence on the battery, and the suitable working temperature of the battery of the electric vehicle is generally 0-30 ℃. Because the suitable temperature of the battery core is 0-30 ℃, the activity of the battery core can be influenced by overhigh temperature and overlow temperature, irreversible damage can be caused, and the service life of the battery core can be influenced. When the battery temperature is too low, the battery capacity is reduced, and excessive discharge is likely to occur, thereby shortening the battery life.
According to the invention, by designing the monitoring module 003, when the monitoring module 003 monitors that the battery is in the low-temperature working range of the battery, the monitoring module 003 sends a signal to the monitoring module 001, the monitoring module 001 receives the signal and forms an instruction, and the first light alarm 008 gives an alarm, so that the alarm prompts a user that the time for starting the vehicle at each time does not exceed 5 seconds, and the vehicle is not required to be started repeatedly in case of failure of starting for the first time. Since continuous starting of the engine when the vehicle is started may cause damage to the battery due to over-discharge, the re-starting time interval is not less than 5 seconds. After the vehicle is started, the temperature of the battery is gradually increased in the starting process of the battery, and when the normal working temperature range of the battery is reached, the first light alarm 008 stops working;
when the monitoring module 003 monitors that the battery is in a high-temperature working range of the battery, the monitoring module 003 sends a signal to the monitoring module 001, the monitoring module 001 receives the signal and forms an instruction, the second light alarm 009 alarms, the execution module 002 receives the instruction and enables the water channel system 007 to start to work, and liquid working media are utilized to indirectly or directly contact with a heating component through a water channel, absorb heat and bring the heat to an external radiator; meanwhile, liquid in the radiator is cooled in an air cooling mode, the cooled liquid is sent back to the inside of the heating component to absorb heat again, and the liquid is recycled repeatedly until the battery recovers to the normal working temperature range of the battery, and the second light alarm 009 stops working.
When monitoring that the battery is in the battery ultra-high temperature working range by the monitoring module 003, the first light alarm 008 and the second light alarm give an alarm at the same time, and the execution module 002 receives an instruction, and the water channel system 007 starts to work to cool the battery, and meanwhile, the vehicle should immediately find a place to park nearby safely, and start again when waiting for the temperature of the battery of the vehicle to fall into the normal working temperature range of the battery.
The battery management system can prolong the service life of the battery by designing the battery management system, and the current electric quantity and the temperature of the battery are monitored by the monitoring module 003, so that the possibility of power failure in the driving process due to insufficient electric quantity monitoring can be effectively prevented, and particularly when the power failure condition occurs in some remote positions, the power failure condition is avoided by monitoring the temperature of the battery and matching the first light alarm 008 and the second light alarm 009, and corresponding measures can be avoided from being adopted due to overhigh temperature or overlow untimely temperature, so that the service life of the battery is easily influenced, and even the irreversible damage to the battery can be caused.
The above-described embodiments are illustrative of the present invention and not restrictive, it being understood that various changes, modifications, substitutions and alterations can be made herein without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
