, can be by detecting whether the magnitude of voltage of low tension battery is less than preset voltage value, to judge that low tension battery is in individual embodiment
It is no to be in under-voltage condition.
Specifically, the magnitude of voltage of low tension battery can be gathered by voltage collection circuit, the voltage of low tension battery is judged
Whether value is less than preset voltage value, when the magnitude of voltage of low tension battery is less than preset voltage value, judges that low tension battery is in
Under-voltage condition.For example, preset voltage value is 8V, when the magnitude of voltage of the low tension battery of collection is less than 8V, low pressure electric power storage is judged
Pond is in under-voltage condition.
Because entire car controller is powered by low tension battery, so in another embodiment of the present invention, can lead to
Whether can wake up the entire car controller of vehicle, to judge the shape of low tension battery if crossing the control signal of AC charging rifle transmission

Alternating current, converts alternating current to after the direct current required for low tension battery, it is charged, solved due to low tension battery
Brownout causes vehicle to start the problem of can not charging.
During being charged using direct current to low tension battery, be more than when the magnitude of voltage of low tension battery or
During equal to preset voltage value, switch to and low tension battery is continued using vehicle-mounted DCDC to charge.Carried out with reference to Fig. 2 detailed
Explanation.
As shown in Fig. 2 the charging method of the electric automobile includes：
S201, inserts AC charging rifle.
When the battery capacity indication table of electric automobile shows that electricity is relatively low, insertion AC charging rifle fills to electric automobile
Electricity.
Whether S202, the magnitude of voltage of low tension battery is less than 8V.
In this example, it is assumed that preset voltage value is 8V.Specifically, the magnitude of voltage of low tension battery is gathered, judges low
Press whether the magnitude of voltage of battery is less than 8V.
S203, obtains alternating current from AC charging rifle, is converted into direct current and low tension battery is charged.
When the magnitude of voltage of low tension battery is less than 8V, low tension battery is in under-voltage condition.At this moment, from alternating current rifle
Alternating current is obtained, the alternating current of acquisition is converted into direct current, battery charged using the direct current.
S204, is charged using vehicle-mounted DCDC to low tension battery.
Insert after AC charging, if the magnitude of voltage of the low tension battery of collection is more than or equal to 8V, by vehicle-mounted
DCDC obtains direct current from high voltage power battery, and the direct current of acquisition is changed into the direct current of low pressure electric power storage needs, and utilization should
Direct current charges to low tension battery.
In addition, if the magnitude of voltage of the low tension battery of collection is less than 8V, low tension battery is carried out using direct current
During charging, can every preset time gather low tension battery magnitude of voltage, judge low tension battery magnitude of voltage whether
More than or equal to 8V.
When the magnitude of voltage of low tension battery is more than or equal to preset voltage value 8V, that is to say, that low tension battery is
During from being changed into normal condition from under-voltage condition, entire car controller can be with normal work, so that vehicle-mounted DCDC can also normal work.
So, the direct current after alternating current conversion that can be from using power network charges to low tension battery, is switched to using vehicle-mounted
DCDC power takings from high voltage power battery continue to charge to low tension battery.
Specifically, because the voltage ratio of high voltage power battery output is higher, it is impossible to directly low tension battery is filled
Electricity, therefore the direct current in high voltage power battery is converted into using vehicle-mounted DCDC the constant current required for low tension battery, and
Low tension battery is charged using the direct current.
In addition, when the magnitude of voltage of low tension battery is more than or equal to preset voltage value, that is to say, that low tension battery
During in normal condition, entire car controller is in the state of normal work.At this moment, entire car controller is sent for indicating to high pressure
The control signal that electrokinetic cell is charged.After the control signal is received, the alternating current that will be exported in AC charging rifle, conversion
Direct current into required for high voltage power battery, is charged using the direct current to high voltage power battery.
It in summary it can be seen, in an embodiment of the present invention, when low tension battery is in under-voltage condition, obtained from power network
Alternating current is taken, is converted alternating current to after direct current, low tension battery is charged.After charging a period of time, when low pressure stores
When the magnitude of voltage of battery is more than or equal to preset voltage value, it is switched to and utilizes vehicle-mounted DCDC by the direct current in high voltage power battery
Electricity is converted into the direct current of low tension battery needs, and low tension battery is charged using the direct current.
After insertion AC charging rifle, the CC signals (charging connection confirmation signal) that can also be sent according to AC charging rifle
Whether full-vehicle control can be waken up, to determine to charge to low tension battery with which kind of mode.With reference to Fig. 3, by another
One embodiment illustrates the charging method of electric automobile proposed by the present invention.
As shown in figure 3, the charging method of the electric automobile includes：
S301, inserts AC charging rifle.
When the battery capacity indication table of electric automobile shows that electricity is relatively low, insertion AC charging rifle fills to electric automobile
Electricity.
Whether S302, the CC signals that detection AC charging rifle is sent can wake up entire car controller.
After the charging jacks that AC charging rifle is inserted to electric automobile, if AC charging rifle and charging electric vehicle jack
Connection is correct, then AC charging rifle sends CC signals (charging connection confirmation signal).
Receive after CC signals, judge whether CC signals can wake up entire car controller, i.e. entire car controller and be in normally
State.
If it is judged that entire car controller is in normal condition, i.e., when CC signals can wake up entire car controller, then perform
S303；Otherwise S304 is performed.
S303, is charged using vehicle-mounted DCDC to low tension battery, into normal charging condition.
If CC signals can wake up entire car controller, it is exactly that entire car controller is in normal condition to be also, then utilizes car
Carry DCDC to be charged to low tension battery, that is, enter the shape normally charged with vehicle-mounted DCDC to low tension battery
State.Specifically, vehicle-mounted DCDC obtains the higher direct current of magnitude of voltage from high voltage power battery, and direct current is converted into low pressure stores
The direct current that battery needs, is charged using the direct current to low tension battery.
S304, obtains alternating current from AC charging rifle, is converted into direct current and low tension battery is charged.
If CC signals can not wake up entire car controller, low tension battery can not be charged using vehicle-mounted DCDC.Due to
The alternating current that AC charging rifle one end is connected in power network, other end connecting electric automobile, such power network can just be filled by exchange
Electric rifle is input in electric automobile.
