[0079] Based on this, the present application embodiment provides a battery charging method, referring to Figure 2 , Figure 2 This is a flow chart of the first embodiment of the battery charging method of the present application.

[0080] In this embodiment, the battery charging method includes steps S10 to S40:

[0081] Step S10, obtaining the charging time set by the user and the battery status information of the target battery;

[0082] The charging time is set to the target time required for the target battery to be charged from the current initial power to the target power, which is set by the user based on his / her needs. The initial power is the current power of the target battery when it is not charged. The target power is the power that the target battery needs to reach when charging is completed. In this embodiment, the target power is a parameter set by the user. In other embodiments, the target power may also be a pre-set fixed parameter, such as 100% power.

[0083] The target battery is a power battery to be charged. In this embodiment, the battery on the vehicle to which the charging device is connected is the target battery.

[0084] The battery status information may include power information of the target battery (eg, initial power and / or target power and / or target charging capacity, etc.) and / or temperature information of the target battery, etc.

[0085] Step S20, determining a reference charging time of the target battery according to the battery status information;

[0086] The reference charging time may include at least one of the following: the minimum charging time allowed for charging the target battery from an initial charge to a target charge, the maximum charging time allowed for charging the target battery from an initial charge to a target charge, a reference value of the charging time required for charging the target battery from an initial charge to a target charge, and the like.

[0087] Different battery status information corresponds to different reference charging times.

[0088] In one implementation, the charging time corresponding to the current power information of the target battery can be determined as a reference charging time based on a preset correspondence between the preset power information and the charging time. In another implementation, the preset correspondence between the power information and the charging time can be obtained based on the temperature information of the target battery. Different temperature information corresponds to different preset correspondences. Based on the preset correspondence, the charging time corresponding to the current power information of the target battery is determined as the reference charging time. The preset correspondence may include a mapping relationship or a relational expression. In yet another implementation, the ratio of the target charge to the preset charging current is used as a reference charging time. The preset charging current may be a charging current set by the user, a preset fixed current, or a current calculated based on the initial power.

[0089] Step S30, determining a current control parameter of the target battery according to the set charging time and the reference charging time;

[0090] The current in the target battery charging process corresponding to the current control parameter may be a fixed current or a variable current. The current control parameter may include a target current in the target battery charging process or a target corresponding relationship between a state parameter (such as charging time or current power) in the target battery charging process and the charging current.

[0091] In one implementation, the size relationship between the set charging time and the reference charging time is determined, and the charging current corresponding to the size relationship is used as the current control parameter, or the current control parameter is determined based on the current determination method corresponding to the size relationship.

[0092] In another implementation, a relationship between the set charging time, the reference charging time and the current control parameter can be pre-established, and the current control parameter can be calculated by substituting the set charging time and the reference charging time into the relationship.

[0093] Step S40: charging the target battery according to the current control parameter.

[0094] When the current control parameter includes a target current, the target battery is charged with the target current until the charging end condition is reached. For example, when the current control parameter includes a minimum charging current, the target battery is charged with the minimum charging current.

[0095] When the battery control parameters include the correspondence between the state parameters and the charging current, the state parameters of the target battery can be detected in real time or at set intervals, and the corresponding charging current of the target battery can be obtained from the detected state parameters in the correspondence, and the target battery can be charged with the determined charging current.

[0096] In the process of charging the target battery according to the battery control parameters, the current actually output by the charging device is greater than or equal to the charging current corresponding to the battery control parameters.

[0097] The present embodiment provides a battery charging method, which controls the current control parameters in the battery charging process based on the set charging time set by the user and the reference charging time corresponding to the battery status information of the battery, thereby ensuring that the charging current in the battery charging process no longer only considers the actual status of the battery, but is also set in combination with the charging time required by the user, which can avoid the actual charging time of the battery from seriously deviating from the user requirements, thereby improving the matching degree of the battery charging time with the user requirements.

[0098] In a feasible implementation manner, the reference charging time includes a maximum charging time and a minimum charging time. Figure 3 , step S30 includes steps S31 to S33:

[0099] Step S31, when the set charging time is greater than or equal to the maximum charging time, determining the minimum charging current as the current control parameter;

[0100] The minimum charging current may be the minimum current allowed during the charging process of the target battery. In this embodiment, the minimum charging current is the current set by the user. In other embodiments, the minimum charging current may also be a rated minimum current pre-set based on the characteristics of the target battery and / or the charging device, and the minimum current set by the user is greater than or equal to the rated minimum current here.

[0101] When charging the target battery according to the current control parameter, charging the target battery with a minimum charging current is maintained.

[0102] Based on this, it is beneficial to ensure that the charging time is more compatible with user needs while saving charging energy consumption.

[0103] Step S32, when the set charging time is less than or equal to the minimum charging time, determining a preset corresponding relationship as the current control parameter, wherein the preset corresponding relationship is a corresponding relationship between the power of the target battery and the charging current set based on the life requirement of the target battery;

[0104] The preset corresponding relationship is to ensure that the battery life of the target battery can reach the maximum charging current corresponding to the target battery at different power levels allowed by the preset life.

[0105] When charging the target battery according to the current control parameter, the charging current changes with the current power of the target battery, and the current power of the target battery can be detected in real time, and the target battery is charged according to the charging current corresponding to the current power in the preset corresponding relationship. In this embodiment, the preset corresponding relationship includes different preset power intervals and the charging currents corresponding to each of the preset power intervals, and the charging current corresponding to the preset power interval where the current power is located can be determined as the target current, and the target battery is charged according to the target current.

[0106] Based on this, it is helpful to ensure that the charging time is as close as possible to the charging time set by the user to improve the matching degree with the user's needs while ensuring the service life of the target battery.

[0107] Step S33, when the set charging time is greater than the minimum charging time and less than the maximum charging time, determine the current control parameter according to the current initial power of the target battery, the target power of the target battery, the preset corresponding relationship and the set charging time.

[0108] In one implementation, the preset corresponding relationship can be adjusted according to the initial power, the target power and the set charging time to obtain the target corresponding relationship, and the current control parameters include the target corresponding relationship. In another implementation, the average charging current and reference time for charging the target battery from the initial power to the target power can be determined according to the preset corresponding relationship, the initial power and the target power, and the average charging current can be corrected according to the relationship between the set charging time and the reference time to obtain the target average charging current, and the current control parameters may include the target average charging current. In yet another implementation, the target charging capacity can be determined according to the power difference between the target power and the initial power, the target charging current can be determined according to the ratio of the target charging capacity to the set charging time, the reference current data for charging can be determined based on the preset corresponding relationship, and the current control parameters can be determined according to the target charging current and the reference current data.

[0109] Based on this, it is beneficial to improve the matching degree between charging time and user needs while taking into account battery life and energy consumption.

[0110] The execution order of the above steps S31 to S33 is not specifically limited.

[0111] In a feasible implementation manner, the preset correspondence relationship includes different preset power intervals and the charging current corresponding to each preset power interval, and the step of determining the current control parameter according to the initial power of the target battery, the target power of the target battery, the preset correspondence relationship and the set charging time includes: when the initial power and the target power are both in the same preset power interval, the target charging current is determined according to the ratio of the power difference between the target power and the initial power to the set charging time, and the current control parameter includes the target charging current; when the initial power and the target power are in different preset power intervals, the preset correspondence relationship is adjusted according to the initial power, the target power and the set charging time to obtain the target correspondence relationship between the power of the target battery and the charging current, and the current control parameter includes the target correspondence relationship.

[0112] In this embodiment, the target charging current Im can be determined based on the following relationship: Im = (SOCcutoff-SOCinit)*Qn*SOH / (TE / a), wherein SOCcutoff is the target power, SOCinit is the initial power, TE is the set charging time, SOH is the health status value, Qn is the rated power of the target battery, and a is a preset coefficient (for example, 60, etc.).

[0113] In this embodiment, the preset corresponding relationship is adjusted according to the user charging mode, initial power, target power and set charging time set by the user to obtain the target corresponding relationship between power and charging current. The preset corresponding relationship may include a relational expression or a mapping table.

[0114] The charging device may be pre-set with at least two charging modes including a first charging mode (e.g., power-friendly mode), a second charging mode (e.g., life-friendly mode), and a third charging mode (e.g., power and life-combination mode). The user may select one of the at least two charging modes as the user charging mode based on their own needs. Among them, the change amplitude of the charging current in the second charging mode is less than or equal to the preset amplitude; the change amplitude of the charging current in the first charging mode and the third charging mode is greater than the preset amplitude, the charging speed of the first charging mode is greater than the charging speed of the third charging mode, the charging speed of the third charging mode is greater than the charging speed of the second charging mode, the life attenuation of the target battery in the second charging mode is less than the life attenuation of the target battery in the third charging mode, and the life attenuation of the target battery in the third charging mode is less than the life attenuation of the target battery in the first charging mode. The charging current of the first charging mode may include a first current in the early stage of charging and a second current in the later stage of charging, the charging current of the second charging mode may include a third current in the early stage of charging and a fourth current in the later stage of charging, and the charging current of the third charging mode may include a fifth current in the early stage of charging and a sixth current in the later stage of charging, wherein the first current is greater than the fifth current, the fifth current is greater than the third current, the fourth current is greater than the sixth current, and the sixth current is greater than the second current.

[0115] According to the user's charging mode, the target relationship between the initial power, target power, set charging time and the adjustment parameters or adjustment methods of the preset corresponding relationship can be determined. Different user charging modes correspond to different target relationships. Based on the current initial power, target power, set charging time and target relationship, the target adjustment parameter or target adjustment method can be determined. The preset corresponding relationship can be adjusted according to the target adjustment parameter or target adjustment method to obtain the target corresponding relationship.
