The battery management system 103 includes a precharge circuit, a positive relay, a negative relay, a main positive contactor, a main negative contactor, and the like, and is controlled by the power distribution control device 101, so that the voltage and current of the battery system can be monitored in real time.
It should be noted that the structure of the above-described vehicle is shown only for the convenience of understanding the spirit and principle of the present specification, and the embodiments of the present specification are not limited in any way in this respect. Rather, embodiments of the present description may be applied to any vehicle where applicable.
Fig. 2 is a schematic flow chart of a charging method according to an embodiment of the present application.
Referring to fig. 2, the charging method may be applied to the vehicle shown in fig. 1, and the charging method includes the steps of:
step 201, acquiring charging state information of a vehicle in response to a charging operation.
In this embodiment of the present application, the charging state information at least includes: and (3) an output voltage threshold of the charging pile.
Alternatively, the output voltage threshold of the charging pile may be a fixed voltage value, and the output voltage threshold of the charging pile may also be a voltage range, which is not specifically limited in the embodiment of the present application.
In this embodiment of the present application, the output voltage threshold of the charging pile may be a peak voltage of the charging pile, that is, a highest output voltage provided by the charging pile.
In practical application, the charging pile is divided into an alternating current pile and a direct current pile, and as the direct current charging pile adopts three-phase four-wire system power supply, enough power can be provided, and the output voltage and current adjustment range is large, the direct current pile can meet the charging requirements of electric vehicles with different voltage grades such as small electric vehicles, middle bars, buses and the like. In addition, the direct current charging pile can meet the requirement of quick charging, so that the charging pile in the embodiment of the application is a direct current charging pile.
In this embodiment of the present application, the charging operation may be to insert a charging gun of the electric vehicle into the charging stake.
Alternatively, when the charging pile is a dc charging pile, the charging operation may be that the fast charging gun of the electric vehicle is connected to the dc charging pile.
Illustratively, as shown in connection with fig. 1, after the quick charge gun is connected, PDCU101 sends a quick charge gun connection status signal to HU102, and the vehicle notifies the driver of the status of the quick charge gun at that time by illuminating a quick charge gun connection indicator on the dashboard.
In some embodiments, the state of charge information may further include: preset charging parameters and vehicle fault information.
In some embodiments, the state of charge information may further include: current speed of the car, power mode, battery temperature, battery charge, etc.
In practical application, the charging method provided by the embodiment of the application can be used under the condition that the power mode of the vehicle is OFF or low-voltage ON. Wherein, low voltage ON refers to the vehicle in a state that can be driven. When the quick charging gun is inserted, the Ready lamp on the vehicle instrument panel is extinguished, and the quick charging gun connection indicator lamp is lighted.
In an alternative embodiment, when a quick charge gun is connected, an attempt by the driver to start the vehicle is detected, and a prompt to "please remove the gun" is output through HU 102.
Therefore, before the automobile is started, the driver is prompted to remove the charging gun, so that the damage of the charging gun is effectively avoided, and the charging safety of the automobile is ensured.
Step 202, determining a target charging mode of a battery system of the vehicle according to the charging state information.
In this embodiment of the present application, the target charging manner may include a serial charging manner or a parallel charging manner, and the target charging manner may also include charging manners with different charging durations.
In some embodiments, step 202 comprises:
and determining a target charging mode according to the magnitude relation between the output voltage threshold value of the charging pile and the first voltage threshold value.
In an embodiment of the present application, the first voltage threshold may be 800 volts (V).
For example, when the output voltage threshold of the charging pile is greater than or equal to 800V, determining that the target charging mode is series charging; and when the output voltage threshold of the charging pile is smaller than 800V, determining that the target charging mode is parallel charging.
For another example, when the output voltage threshold of the charging pile is greater than or equal to 800V, determining that the target charging mode is charging for 40 minutes; and when the output voltage threshold of the charging pile is smaller than 800V, determining that the target charging mode is charging for 6 hours.
Therefore, according to the magnitude relation between the output voltage threshold and the first voltage threshold, automatic adjustment of the charging mode is achieved, and charging experience of a user is improved.
In an alternative embodiment, as shown in connection with fig. 1, the BMS103 detects the highest output voltage of the dc pile to determine the target charging mode.
Step 203, charging the battery system in a target charging mode.
In this embodiment of the present application, the target charging manner is determined according to a magnitude relation between an output voltage threshold of the charging pile and the first voltage threshold.
In some embodiments, step 203 comprises: judging whether the vehicle meets the charging condition or not; if the target charging mode is met, charging the battery system in the target charging mode; if not, outputting prompt information.
In the embodiment of the application, the charging condition satisfies at least one of the following conditions:
the vehicle is stationary;
the direct current charging gun is connected;
the battery is in a standby state;
the motor is in a pre-charge state;
the electric quantity of the battery is smaller than the electric quantity set by a driver;
the battery temperature is normal;
the whole vehicle has no faults.
In the embodiment of the application, the vehicle speed is less than or equal to 2 kilometers per hour (km/h), and the vehicle can be considered to be in a stationary state; the battery system temperature is greater than-20 degrees celsius (°c) and less than 55 ℃ may be considered normal.
In an alternative embodiment, as shown in connection with fig. 1, PDCU101 sends a relay close command to BMS103 after determining that the charging condition is satisfied, causing the power battery relay to close.
The application provides a charging method, which is applied to a vehicle and comprises the following steps: acquiring charging state information of the vehicle in response to the charging operation; wherein the charge state information at least includes: an output voltage threshold of the charging pile; determining a target charging mode of a battery system of the vehicle according to the charging state information; and charging the battery system in a target charging mode. Through the technical scheme that this application provided, under the condition of detecting the operation of charging, acquire the charge state information including the output voltage threshold value of charging the stake at least earlier, confirm the target charge mode of the battery system of vehicle according to charge state information again for the vehicle can be according to the output voltage threshold value dynamic adjustment charge mode that the charging stake provided, and then the charging stake of different charge voltage of adaptation has improved the compatibility when the vehicle charges.
In some embodiments, determining the target charging mode according to the magnitude relation of the output voltage threshold of the charging pile and the first voltage threshold comprises:
if the output voltage threshold of the charging pile is greater than or equal to the first voltage threshold, determining that the target charging mode is a first charging mode; the first charging mode characterizes series charging of a plurality of battery packs in the battery system.
In the embodiment of the application, at least two battery packs are included in the battery system.
For example, as shown in connection with fig. 1, the first charging mode may include the PDCU101 connecting a plurality of battery packs in the battery system in series to increase the voltage of the battery system in a case where the output voltage threshold provided by the dc charging stake is greater than or equal to 800V, so that the dc charging stake can charge the plurality of battery packs connected in series.
Therefore, when the charging voltage provided by the charging pile is larger, the plurality of battery packs in the battery system are charged in series, so that the voltage of the battery system is matched with the charging voltage, the influence on the health of the battery caused by the overlarge charging voltage is effectively avoided, and the safety of the battery system during charging is ensured.
In other embodiments, determining the target charging mode according to the magnitude relation between the output voltage threshold of the charging pile and the first voltage threshold includes:
a1, if the output voltage threshold of the charging pile is smaller than a first voltage threshold, calculating the voltage difference value between every two battery packs of the plurality of battery packs in the battery system of the vehicle;
a2, determining a target charging mode of each battery pack in the battery system according to the voltage difference value between every two battery packs.
In this embodiment of the present application, the voltage difference may be a fixed voltage value, or the voltage difference may be a voltage range, which is not specifically limited in this embodiment of the present application.
For example, the voltage difference may be 2V, or the voltage difference may be 2V to 10V, which is not particularly limited in the embodiment of the present application.
In an alternative embodiment, if the voltage difference is greater than 10V, a notification message "battery cell differential is too large, please overhaul" is output through HU 102.
It can be understood that if the pressure difference of the battery cells of the electric vehicle is too large, the electric vehicle cannot run, but the endurance of the electric vehicle is obviously reduced, and at this time, the electric vehicle needs to be checked and maintained by a driver in time.
In this embodiment of the present application, the target charging manner may include a serial charging manner or a parallel charging manner, and the target charging manner may also include charging manners with different charging durations.
Taking the example that three battery packs are included in the battery system of the vehicle, calculating the voltage difference between each two battery packs of the plurality of battery packs in the battery system of the vehicle may be achieved by:
if the voltage values of battery a, battery b, and battery c are 202.5V, 200V, and 199.8V, respectively, the voltage difference values between each two batteries are 202.5V-200 v=2.5V, 200V-199.8 v=0.2V, and 202.5V-199.8 v=2.7V, respectively;
if the voltage values of battery a, battery b, and battery c are 299.5V, 300V, and 300.4V, respectively, the voltage difference values between each two batteries are 300V-299.5 v=0.5V, 300.4V-300 v=0.4V, and 300.4V-299.5 v=0.9V, respectively.
Therefore, when the output voltage threshold of the charging pile is larger than the first voltage threshold, the voltage difference is calculated first, and then the target charging mode of each battery pack in the battery system is determined according to the voltage difference, so that the battery health is prevented from being influenced by overlarge voltage difference among the battery packs while flexibly selecting the charging mode.
In some embodiments, A2 determines a target charging mode of each battery pack in the battery system according to a voltage difference between every two battery packs, including:
if the voltage difference between the two battery packs is larger than the second voltage threshold, determining that the target charging mode is a second charging mode; the second charging mode is characterized by charging a battery pack with lower voltage in the battery system;
if the voltage difference between every two battery packs is smaller than or equal to the second voltage threshold, determining that the target charging mode is a third charging mode; the third charging mode characterizes parallel charging of a plurality of battery packs in the battery system.
In an alternative embodiment, as shown in connection with fig. 1, if two battery packs are included in the battery system, PDCU101 first compares the pressure differentials of the two battery packs; and if the voltage difference is more than 2V and less than 10V, charging the battery pack with lower voltage.
In this embodiment of the present application, the second charging mode and the third charging mode are not easy to overcharge, and voltage equalization is easy to achieve.
For example, the battery system comprises two battery packs P1 and P2, and the voltages of the P1 and the P2 are compared; if the voltage of the P1 is lower, a command is sent to close a switch S1 corresponding to the P1, and the state of charging the P1 single packet is entered; if the voltage of the P2 is lower, a command is sent to close a switch S2 corresponding to the P2, and the state of charging the P2 single packet is entered; if the voltage difference value of the two groups of batteries is smaller than or equal to 2V, an instruction is sent to close S3, and the parallel charging state of P1 and P2 is entered.
As another example, the battery system includes three battery packs, and the voltage values of battery pack a, battery pack b and battery pack c are 202.5V, 200V and 199.8V, respectively, and then the voltage difference between each two battery packs is 202.5V-200 v=2.5V, 200V-199.8v=0.2V and 202.5V-199.8v=2.7V, respectively; since there is a voltage difference between the two battery packs greater than 2V, the battery pack c having the lowest voltage is charged.
For example, the battery system includes three battery packs, and the voltage values of battery pack a, battery pack b and battery pack c are 299.5V, 300V and 300.4V, respectively, and then the voltage difference between each two battery packs is 300V-299.5 v=0.5v, 300.4V-300 v=0.4v and 300.4V-299.5 v=0.9V, respectively, and the voltage difference between each two battery packs is less than or equal to 2V, so that battery pack a, battery pack b and battery pack c are charged in parallel.
Therefore, the target charging modes of the battery packs in the battery system are determined according to the voltage difference values, and the battery health is prevented from being influenced by overlarge voltage difference between the battery packs while flexibly selecting the charging modes.
In some embodiments, when the charging state information includes preset charging parameters, after step 203, the charging method further includes:
if the battery system meets the preset charging parameters, stopping charging the battery system part;
outputting first prompt information; the first prompt information indicates that the vehicle is charged.
In this embodiment of the present application, the preset charging parameter may be a power value of the battery system preset by the driver.
In this embodiment of the present application, the first prompt message may be "charge complete, please remove the charging gun".
For example, as shown in fig. 1, the BMS103 sends the electric quantity of the battery system to the PDCU101 in real time, and when the PDCU101 detects that the electric quantity of the battery system has reached 80%, sends a charge completion status instruction to the HU102, and the HU102 outputs a prompt message of "charge completion, please remove the charging gun".
Like this, when the battery electric quantity reaches the charging parameter of setting up in advance, output first prompt message and inform the driver for the driver in time knows the charge condition, is favorable to saving time.
Optionally, referring to fig. 1, after outputting the first prompt information, the charging method further includes: after the charge completion state command is sent, the battery system is still charged, the BMS103 responds to the command of the PDCU101, the main positive contactor and the main negative contactor are sequentially disconnected, the main contactor disconnection process is completed, and the main contactor state and the BMS103 state are fed back to the PDCU101. Thus, the possibility of overcharge can be reduced, and the damage to the health of the battery can be effectively avoided.
In some embodiments, when the state of charge information includes vehicle fault information, before step 203, the charging method further includes:
stopping charging the battery system;
outputting second prompt information; wherein the second prompt information characterizes that the vehicle has faults
In this embodiment of the present application, the vehicle fault information may be a BMS fault, and the vehicle fault information may also be a problem of excessive pressure difference between the monomers, leakage, contact of the wire harness, etc., which is not specifically limited in this application.
In this embodiment of the present application, the second prompt information may be "charge abnormality, please overhaul".
For example, as shown in fig. 1, when the PDCU101 detects a serious fault of the vehicle, it sends a charging prohibition instruction to the BMS103, and sends a vehicle fault instruction to the HU102, and the HU102 outputs a prompt message of "abnormal charging, please overhaul".
Therefore, when the vehicle fails, the battery system is forbidden to be charged, and the second prompt information is output, so that accidental sending can be avoided, and the safety of the vehicle and a driver is ensured.
Fig. 3 is a schematic flow chart of a charging method according to an embodiment of the present application.
Referring to fig. 3, taking the example of the battery system including two battery packs in combination with the above embodiment, the charging method includes the following steps:
step 301, obtaining the highest output voltage of the charging pile.
Step 302, judging whether the highest output voltage exceeds 800 volts; if yes, go to step 304; if not, go to step 304.
Step 303, charging in series.
Step 304, calculating a voltage difference value.
Step 305, judging whether the voltage difference exceeds 2 volts; if yes, go to step 306; if not, go to step 307.
Step 306, parallel charging.
Step 307, charging one of the batteries.
Therefore, whether to charge in series is judged according to the highest output voltage value of the charging piles, and whether to charge in parallel or charge one group of batteries is judged according to the calculated voltage difference value of the two groups of batteries, so that the charging mode can be dynamically adjusted, the vehicles adapt to the charging piles with different charging voltages, and the compatibility of the vehicles in charging the battery systems is improved.
It should be noted that, in this embodiment, the descriptions of the same steps and the same content as those in other embodiments may refer to the descriptions in other embodiments, and are not repeated here.
