Therefore, there is a need to develop a method for maintaining the electric quantity of the HEV hybrid system, so that the electric quantity of the power battery can be maintained in a reasonable range even when the vehicle is not used after being stored for a long time, and the power battery cannot be used due to power supply.
At present to the feed problem that HEV power battery self-discharge leads to, thereby the general way is that the performance of promoting power battery slows down its self-discharge condition, and the energy management algorithm of whole car also needs to guarantee to keep power battery's SOC at reasonable interval before stopping at every turn simultaneously, through above method, can guarantee that most vehicles can not take place in the life cycle because the vehicle deposits the condition that leads to power battery feed and can't use the vehicle for a long time. However, the difficulty of improving the performance of the power battery is high, and the cost is high, so that a power battery electric quantity keeping method which is low in cost and easy to use needs to be developed, the electric quantity level of the power battery is monitored through a vehicle background, when the electric quantity of the power battery is low, an engine is automatically started to charge the power battery, and as long as the engine does not lack fuel, the electric quantity of the power battery is always in a reasonable interval, so that the situation that the power battery is fed due to self-discharge of the power battery and further the use of a user is influenced is avoided.
Referring to fig. 1, fig. 1 shows a schematic structural view of a two-motor hybrid configuration. The system comprises an engine 1, a reduction gear mechanism 4 connected with the engine 1 through a torsional damper 3, and a generator connected with the reduction gear and the mechanism 4; the clutch 5 is connected with the reduction gear mechanism 4; a driving motor 6 connected with the clutch 5, and a differential 7 connected with the driving motor 6. The application provides a method for maintaining the electric quantity of a HEV hybrid power battery, which is a management method provided for the system. This will be explained in detail below.
The embodiment of the application provides a method for keeping the electric quantity of a hybrid electric power battery of an HEV (electric vehicle), and aims to provide a method for remotely controlling the power battery to supplement electricity. The following is a detailed description.
The method for keeping the electric quantity of the HEV hybrid power battery provided by the embodiment of the application comprises the following steps:
step 001: acquiring power battery SOC information of a vehicle and locking information of the vehicle;
specifically, no matter whether the whole vehicle is in a dormant state or not, the vehicle-mounted TBOX periodically sends the SOC information of the power battery, the locking information of the vehicle and the state information of four doors and two covers of the vehicle to a data background server of a manufacturer.
Step 002: when the SOC information of the power battery of the vehicle is lower than a first set value and the vehicle is locked, reminding information is sent to a user according to set conditions;
specifically, the reminding information is sent to the user through a background server of a vehicle manufacturer according to the set conditions. The first set value is: the SOC value of the power battery is lower than the lower limit SOC value of the start of the power battery by-5 percent. When the data background server monitors that the SOC value of the power battery is lower than the lower limit SOC value of the power battery starting up by-5%, the data background server reminds a user that the SOC of the whole vehicle is low in a short message mode, and the user needs to start the vehicle to charge the power battery, or reminds the user in a message mode through a mobile phone client controlled by the vehicle remotely.
The method comprises the following steps of sending reminding information to a user through a background server of a vehicle manufacturer according to set conditions, and specifically comprises the following steps:
and sending a reminding message to a user once when the SOC of the power battery of the vehicle is reduced by 1%. Specifically, when the SOC of the power battery is lower than the lower limit SOC value of the power battery starting up to 5%, the user is reminded once the SOC is reduced by 1%, and the reminding mode can be a short message mode or a message mode for remotely controlling the mobile phone client.
Step 003: when the SOC information of the power battery of the vehicle is lower than a second set value, acquiring the oil quantity information of the vehicle;
specifically, when the SOC of the power battery is lower than the lower startup limit SOC value of the power battery by-10%, it is indicated that the user does not take care of the previous startup charging reminder. At this time, the vehicle needs to start by itself to maintain the SOC of the power battery, and the vehicle is remotely started, so that the vehicle state, whether the vehicle is in a locked state, whether the front cabin cover is in a locked state, and whether the vehicle fuel is sufficient need to be confirmed.
Step 004: and when the oil quantity information of the vehicle exceeds a third set value, controlling the vehicle to remotely start an engine to charge a power battery of the vehicle until the SOC information of the power battery exceeds the first set value.
Specifically, the third setting value is: when the vehicle charges the power battery to exceed the first set value, the vehicle can still be supported to run for an oil quantity value of not less than 50Km based on the NED fuel consumption rate of the vehicle.
When the fuel quantity information of the vehicle exceeds a third set value, the vehicle is indicated as fuel-rich, and the fuel-rich means that the vehicle can be supported to run for more than 50km when running at the NEDC fuel consumption rate based on the NEDC fuel consumption rate of the vehicle. And if the vehicle is in a locked state, the front cabin cover is in a locked state, and the conditions such as oil and the like are met, starting the engine to charge the power battery.
In addition, before the vehicle is controlled to be remotely started to charge the power battery of the vehicle, the vehicle is controlled to display a prompt message that the vehicle is awakened;
and after the power battery of the vehicle is charged, closing the prompt message of the vehicle.
The prompt information is as follows: the headlights of the vehicle are turned on and the front cooling fan of the vehicle is turned on to 50% of the speed.
In particular, when charging is performed, charging may be performed under different conditions. Specifically, the environment of the position of the vehicle can be detected; determining a charge amount to the power battery based on an environment in which the vehicle is located.
When the vehicle is determined to be in the closed environment, controlling the charging quantity of the power battery to exceed 2% of the SOC value of the starting lower limit of the power battery;
and when the vehicle is determined to be in an open environment, controlling the charging amount of the power battery to exceed 5% of the SOC value of the starting lower limit of the power battery.
In addition, when a driver is detected to unlock the vehicle during a charging process for a power battery of the vehicle, the engine is stopped from charging the power battery.
As can be seen from the above description, the user is reminded according to the SOC information of the power battery and the SOC information, and the power battery is charged by remotely controlling the engine of the vehicle under the condition that the power battery is not charged by the user, so that the electric quantity of the power battery of the vehicle is ensured to be sufficient.
For the convenience of understanding the above method, the flow steps thereof will be described in detail with reference to fig. 2.
Referring to fig. 2, in the method for maintaining the electric quantity of the hybrid power battery of the HEV provided by the embodiment of the present application, regardless of whether the entire vehicle is in a sleep state, the vehicle TBOX periodically sends the SOC information of the power battery, the locking information of the vehicle, and the state information of the four doors and two covers of the vehicle to the data backend server of the manufacturer.
When the data background server monitors that the SOC value of the power battery is lower than the lower limit SOC value of the power battery starting up by-5%, the data background server reminds a user that the SOC of the whole vehicle is low in a short message mode, and the user needs to start the vehicle to charge the power battery, or reminds the user in a message mode through a mobile phone client controlled by the vehicle remotely;
when the SOC of the power battery is lower than the lower limit SOC value of the power battery starting up by-5%, reminding the user once when the SOC is reduced by 1%, wherein the reminding mode can be a short message mode or a message mode of remotely controlling the mobile phone client;
and when the SOC of the power battery is lower than the lower starting limit SOC value of the power battery by-10%, indicating that the user does not take care of the previous starting charge reminding. At this time, the vehicle needs to be started by itself to maintain the SOC of the power battery, and the vehicle is remotely started by the vehicle, so that the vehicle state needs to be confirmed, whether the vehicle is in a locked state, whether a front cabin cover is in a locked state, and whether the vehicle fuel is sufficient (the fuel is sufficient, namely the vehicle can be supported to run for more than 50km when running at the NEDC fuel consumption rate based on the NEDC fuel consumption rate of the vehicle, and if the two conditions are met, the operation of starting the engine to charge the power battery is carried out; before starting the engine, it is necessary to alert the vehicle that it has been awake and is about to start by the vehicle emitting a relevant signal: the front lamp is automatically started, and the cooling fan at the front end of the vehicle is started to 50% of the rotating speed; when a prompt signal before the engine is started is sent out for 10 seconds, the vehicle control unit controls the engine to be started and performs series power generation, and after the engine is started, the prompt signal before the engine is started is automatically turned off (a fan is turned off and a headlamp is turned off);
the method comprises the steps that the vehicle is started remotely, so that the starting time of an engine is determined according to the environment of the vehicle, after the engine is started, the environment of the vehicle is judged to be a closed environment (such as an independent garage) or an open environment (an open parking lot) through a look-around camera of the vehicle, if the vehicle is in the closed environment, the starting time of the engine does not need to be too long so as to avoid the pollution of the closed environment caused by excessive tail gas of the engine, and at the moment, the target SOC for charging the power battery is set to be +2% of the starting lower limit SOC value of the power battery; if the vehicle is in an open environment, the starting time of the engine can be longer, and the target SOC for charging the power battery is set to be +5% of the starting lower limit SOC value of the power battery;
when the SOC of the power battery rises above a target value, the vehicle controller controls the engine to stop, and the vehicle enters a dormant state again after being powered off;
in the process of starting and charging the engine remotely, if a driver unlocks the vehicle, the engine remote starting function is closed, and the engine is shut down.
