Specific embodiment
To keep the technical problem to be solved in the present invention, technical solution and advantage clearer, below in conjunction with attached drawing and tool
Body embodiment is described in detail.
The embodiment of the present invention is directed in the prior art during to charge the battery, due to that can not detect battery
Current electric quantity and stop as battery charging, the problem of leading to the discharged or defective battery, a kind of battery charging side is provided
Method, entire car controller, electric quantity monitoring device and electric car, during realizing to charge the battery, when can't detect electric power storage
When the current electric quantity in pond, it is battery charging according to pre-stored electricity-time threshold relation table, avoids the electric power storage
Pond is in power shortage state always, improves the driving experience of user.
As shown in Figure 1, one embodiment of the invention provides a kind of accumulator charging method, including：
Step 11, when electric car is in power-down state, the electric quantity monitoring for monitoring battery current electric quantity is obtained
The wake-up signal that device is sent；
In the present embodiment, after user carries out electrically operated under vehicle to the electric car, the electric car is in down
In a dormant state, battery is the power supply of electric quantity monitoring device to the components such as electricity condition, entire car controller and car body controller, makes institute
Electric quantity monitoring device is stated when the electric car is in power-down state, the current electric quantity of the battery is monitored, to realize
It is in time battery charging when the current electric quantity of the battery is less than the second default electricity.
Step 12, after receiving the wake-up signal, the battery that the electric quantity monitoring device is sent is received
Current electric quantity, and store the current electric quantity.
In the present embodiment, after the entire car controller receives the wake-up signal that the electric quantity monitoring device is sent, institute
It states entire car controller and wake-up states is switched to by dormant state, when the entire car controller is by the electric quantity monitoring data bits
Afterwards, in the state of normal work, so as to pass through controller LAN (Controller Area Network, abbreviation：
CAN) the current electric quantity for the battery that electric quantity monitoring module described in bus real-time reception is sent.Wherein, it should be noted that
After the entire car controller receives the current electric quantity, the entire car controller can store the current electric quantity, realize

When front hatch cover is in close state, car door is in close state, and does not receive fast charge signal, trickle charge signal and remote
When process control signal, wake-up signal is sent to the entire car controller.
In the present embodiment, if under electric car after electricity, since user forgets that closed door or front hatch cover, i.e., the described car door are
Opening state or the front hatch cover are in an open state, then the car body controller send that front hatch cover is in the open state or car door at
In open state, the electric quantity monitoring device will be considered that the family that comes in handy operates the electric car, in order to ensure people
Body safety, forbidding high-voltage electricity on the electric car is battery charging.Certainly, if user by terminal to described electronic
Automobile sends remote control signal, alternatively, the fast charge socket or trickle charge socket that have charging gun to be inserted into the electric car, the electricity
Amount monitoring device family of also thinking to come in handy operates the electric car, and the state of the current electric car is unsatisfactory for
High-voltage electricity is that the condition of battery charging increases the battery it is therefore not necessary to wake up the entire car controller on vehicle
Electric quantity consumption.
The embodiment of the present invention has been ensured described by the collaborative work of the electric quantity monitoring device and the entire car controller
Charge function of the battery in power shortage state, it is during the charging process, described whole when the electric quantity monitoring device occurs abnormal
Vehicle controller can also according to the current electric quantity of the battery of storage and pre-stored electricity-time threshold relation table after
Continue and charge for the battery, avoids in the prior art, current electricity of the entire car controller monitoring less than the battery
Amount then stops being that the battery charges, and causes the battery to be in power shortage state, improves user experience.
The embodiment of the present invention also provides a kind of computer readable storage medium, is stored thereon with computer program (instruction),
The program (instruction) realizes following steps when being executed by processor：
When electric car is in power-down state, the current electric quantity of battery is monitored；In the current electric quantity less than second
Default electricity wakes up vehicle when each component of electric car is in non-working condition and does not receive the control signal of user's triggering
