Specific embodiment
In order to which the technical features, objects and effects of invention are more clearly understood, the Detailed description of the invention present invention is now compareed
Specific embodiment.
Inventor by the existing method when electric car is stored for a long time, to charge to 12V battery into
Row analysis, it is found that it has the following disadvantages:
One, it charges, is then will lead to 12V battery every Fixed Time Interval: if interval is too long, it is likely that
The electricity of 12V battery, which has exhausted, does not have started charging, if car owner uses vehicle at this time, can not start；Alternatively, if when being spaced
Between it is too short, then continually start charging process, will lead to the charge control module frequent starting of vehicle, increase to charge control
The loss of module；
Two, when starting charging, the SOC (State of Charge, remaining capacity) of power battery is not considered, if dynamic
The SOC of power battery is too low, timing star t-up discharge repeatedly, or there are the danger of power battery over-discharge.
Fig. 1 is the low tension battery charge control method flow chart that one embodiment of the invention provides, the specific steps of which are as follows:
Step 101: after electric vehicle is static, the voltage of low tension battery management system real-time detection low tension battery.

When pressure, wake up VCU (Vehicle Control Unit, full-vehicle control unit), so that: VCU wakes up DC-DC (Direct
Current-Direct Current, DC power supply DC power) equipment, so that DC-DC equipment starts as low tension battery
Charging.
Step 103: when low tension battery management system detects that the voltage of low tension battery reaches preset charged and terminates electricity
When pressure, closes VCU and wake up.
As it can be seen that 101-103 through the above steps, after electric vehicle is static, the voltage of real-time detection low tension battery, and
When voltage is less than preset charged starting voltage, starts the charging process to low tension battery, avoid unnecessarily frequent starting
Charging process reduces the loss to charging module, and avoids power battery over-discharge.
In practical applications, in step 102, low tension battery management system wakes up VCU and further comprises later: receiving

It is issued when the voltage of battery is less than preset charged starting voltage to VCU.
The voltage for the low tension battery that step 202:VCU is sent in real time according to low tension battery management system finds low pressure
The voltage of battery reaches preset charged end voltage, then closes the wake-up of DC-DC equipment.
As it can be seen that 201-202 through the above steps, is less than preset charged in the voltage for detecting low tension battery and starts voltage
When, VCU is waken up, to wake up the starting of DC-DC equipment to the charging process of low tension battery, is avoided when electric vehicle is static
Unnecessarily frequent starting charging process reduces the loss to charging module, and avoids power battery over-discharge.
In practical applications, in step 201, VCU receive the wake-up signal that low tension battery management system is sent after,
It further comprise waking up BMS (Battery Management System, battery management system) before waking up DC-DC equipment,
The SOC for receiving the power battery that BMS is sent, judges whether the SOC of power battery is greater than preset charged starting SOC, if being not more than,
Then close BMS wake-up；If more than, then execute wake up DC-DC equipment movement.Through this process, power electric can be further avoided
Pond over-discharge improves the service life of power battery.
In practical applications, in step 202, VCU discovery low tension battery voltage reach preset charged end voltage it
After further comprise, close BMS wake up.
In practical applications, low tension battery is most common such as: 12V battery.

Awake DC-DC equipment, DC-DC equipment begin through rigid line and charge to 12V battery, go to step 312.
Step 308:VCU stops waking up by rigid line to BMS output wake-up voltage signal to close BMS, under BMS high pressure
Electricity, into dormant state, this process terminates.
Step 309:12V battery management system receives the current SOC for the power battery that VCU forwarding comes, and judges power
Whether the current SOC of battery is greater than preset charged starting SOC, if so, executing step 310；Otherwise, step 311 is executed.
Step 310: when 12V battery management system detects that the voltage of 12V battery reaches preset charged end voltage,
After then waiting preset duration, stop exporting wake-up voltage signal to VCU to close VCU wake-up, return step 302 by rigid line.
After step 311:12V battery management system waits preset duration, stop exporting wake-up voltage to VCU by rigid line
To close VCU wake-up, this process terminates signal.
Step 312: when VCU detects that the voltage of 12V battery reaches preset charged end voltage threshold value, stopping passes through hard
Line exports wake-up voltage signal to BMS and DC-DC equipment to close BMS wake-up and DC-DC equipment and wake up, and electricity under vehicle enters
Dormant state, return step 302.
It should be noted that step 306 and step 309 have no successive point of execution sequence, when VCU receives BMS hair
When the current SOC of the power battery come, it is carried out step 306；When 12V battery management system receives, VCU forwarding is next to be moved
When the current SOC of power battery, it is carried out step 309.
