Detailed Description
In order to make the above and other features and advantages of the present invention more apparent, the present invention is further described below with reference to the accompanying drawings. It is understood that the specific embodiments described herein are for purposes of illustration only and are not intended to be limiting.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, it will be apparent to one of ordinary skill in the art that the specific details need not be employed to practice the present invention. In other instances, well-known steps or operations are not described in detail to avoid obscuring the invention.
Fig. 1 schematically shows a flow diagram 100 of a method for charging a battery according to an embodiment of the invention. The method 100 may comprise a receiving step 101, a generating step 102, a calculating step 103 and a charging control step 104.
The method starts with a receiving step 101. In a receiving step 101, a charge setting signal is received, the charge setting signal indicating a desired charge speed level for the battery. The charge setting signal may come from a user of an object in or to which the battery is located, such as, but not limited to: vehicles, such as electric vehicles or hybrid vehicles; other objects use rechargeable batteries. Here, the battery may be a variety of possible rechargeable batteries.
In a generating step 102, a charging control signal indicative of the desired charging speed level is generated in response to the charging setting signal.
In a calculating step 103, a charging current limit value is calculated based on the desired charging speed level and the maximum and minimum allowable charging current values of the battery. The calculation step 103 may employ a variety of possible calculation approaches. In an embodiment, the calculation process for calculating the charging current limit value may include a process as shown in fig. 2, which will be described later. The maximum allowable charging current value and the minimum allowable charging current value for a particular battery may be determined in various possible ways, or may be predetermined. For example, the maximum allowable charging current value of the battery may be a value of a maximum charging current that a charging controller for the battery is allowed to provide, and the minimum allowable charging current value of the battery may be a minimum allowable charging current value specified by a relevant standard such as a national standard or an industry standard.
In a charge control step 104, a charge controller for the battery is instructed to charge the battery with an actual charge current value that is not higher than the charge current limit value. The actual charging current value may be related to a variety of factors, provided that the calculated charging current limit value is not exceeded. Taking a battery as an example of a vehicle battery, the various factors may include, for example but not limited to: the capacity of the battery, the state of charge of the battery, relevant parameters of the charging equipment such as a charging pile, the temperature difference between the environment inside and outside the vehicle, the load of the charging equipment, the voltage difference of single batteries included in the battery and the like. For example, for a given charging current limit value, in the case where the actual charging current value is not higher than the charging current limit value, when the room temperature is 0 ℃, the actual charging current value may be 1-2A, even 0A; at room temperature of 20 ℃, the actual charging current value may be 30A.
Depending on the circumstances, the desired charge speed level may or may not be one of a plurality of preset charge speed levels for the battery. The plurality of preset charging speed levels may include two or more preset charging speed levels, each of which may correspond to or indicate a different expected charging speed or range of charging speeds.
In one embodiment, the plurality of preset charging speed levels includes a first charging speed level, a second charging speed level and a third charging speed level. The first charge speed level represents a high charge speed level corresponding to or indicative of a relatively high expected charge speed or range of charge speeds; the second charge speed level represents a low charge speed level corresponding to or indicating a relatively low expected charge speed or charge speed range; the third charge speed level represents a medium charge speed level corresponding to or indicating a medium expected charge speed or charge speed range. Fig. 2 shows an example calculation process for calculating the charging current limit value in the case of this embodiment.
As shown in fig. 2, this example calculation process may include step 2031, step 2032, step 2033, step 2034, step 2035, step 2036, and step 2037.
The calculation may be performed in response to and based on a charge control signal indicative of a desired charge speed level.
At step 2031, it is determined whether the desired charge speed level is the first charge speed level.
If the determination at step 2031 is positive, the process proceeds to step 2032. At step 2032, a charging current limit value is calculated equal to the maximum allowable charging current value.
If the determination at step 2031 is negative, the process proceeds to step 2033. At step 2033, it is determined whether the desired charge speed level is the second charge speed level.
If the determination at step 2033 is positive, the process proceeds to step 2034. At step 2034, a charging current limit value is calculated equal to the minimum allowable charging current value.
If the determination at step 2033 is negative, the process proceeds to step 2035. At step 2035, it is determined whether the desired charge speed level is the third charge speed level.
If the determination at step 2035 is positive, the process proceeds to step 2036. At step 2036, a charging current limit value is calculated equal to the average of the maximum allowable charging current value and the minimum allowable charging current value. In further embodiments, at step 2036, it is possible to calculate a charging current limit value equal to a further value between the maximum allowable charging current value and the minimum allowable charging current value. For example, the maximum allowable charging current value and the minimum allowable charging current value may be given different weights, and then a weighted average of the maximum allowable charging current value and the minimum allowable charging current value may be calculated as the charging current limit value.
If the determination at step 2035 is negative, the process proceeds to step 2037. At step 2037, a charging current limit value is calculated equal to the minimum allowable charging current value.
The condition that the desired charging speed level is not any of the plurality of preset charging speed levels may correspond to a possible error or abnormal condition. For example, such situations may include, for example and without limitation, the following: for some reason, such as communication failure, transmission error, etc., the received charging setting signal is incorrect or does not correctly reflect the charging speed level input or set by the user through the available user control device; the user input or settings via the available user control device are not satisfactory, resulting in the charging setting signal issued via the user control device not being recognized or indicating any of the plurality of preset charging speed levels. Taking a vehicle battery as an example, some of these situations CAN be determined and judged by means of a CAN bus mechanism of the vehicle, for example, a CAN transceiver module of the vehicle CAN judge whether the transmission of the signal is normal and whether the transmitted signal is wrong.
The scheme of the invention can be used for various applications and occasions needing to charge the battery, and is particularly suitable for charging applications and occasions related to the vehicle battery.
In one embodiment, the method of the present invention is used for charging a battery of a vehicle, such as an electric or hybrid vehicle. According to one possible implementation of this embodiment, the vehicle has a charge controller for the battery and a further controller communicatively coupled with the charge controller and configured and adapted to communicate with available user control devices. In this case, the charge setting signal may be transmitted to the additional controller by a user via the user control device, the receiving step, the generating step, the calculating step, and the charge controlling step may be performed by the additional controller, and the charge controlling step may include: the further controller provides the calculated charging current limit value to the charging controller to cause the charging controller to charge the battery at an actual charging current value that is not higher than the charging current limit value.
The charge setting signal may be any suitable form of input, and may be generated and issued in response to user input via available user control devices. The charge setting signal may be defined by a user input implemented via the user control device. The user control device may be in various possible forms, for example in the form of a joystick, in the form of a touch screen, etc. The user may input and signal the charge setting by selecting a key on the user control device. The keys may be various possible operation keys. For example, the operational keys may include a plurality of keys displayed on the touch screen, each key corresponding to a different surface area of the touch screen. For another example, the operation keys may be provided in the form of a joystick including a plurality of keys on the joystick. In one embodiment, the operation keys include a "fast" key, a "slow" key, and a "medium" key. A "fast" key, a "slow" key, and a "medium" key are used to receive input indicative of a user's desired charge speed level, e.g., pressing the "fast" key may cause a charge setting signal indicative of a user's desired charge speed level of a high level (e.g., the first charge speed level described above) to be generated and issued, pressing the "slow" key may cause a charge setting signal indicative of a user's desired charge speed level of a low level (e.g., the second charge speed level described above) to be generated and issued, and pressing the "medium" key may cause a charge setting signal indicative of a user's desired charge speed level of a medium level (e.g., the third charge speed level described above) to be generated and issued. In this way, charge setting signals indicative of different desired charge speed levels may be generated and emitted in response to user input via the control device.

Optionally, the charging controller may communicate the actual charging current value to the user control device via the further controller for provision to a user.
The invention may be implemented as an apparatus for battery charging comprising a processor configured to execute computer instructions to perform part or all of the steps of the method of the invention, i.e. part or all of the following steps: a receiving step in which: receiving a charge setting signal indicating a desired charge speed level for a battery; a generating step in which: generating a charge control signal indicative of the desired charge speed level in response to the charge setting signal; a calculating step in which: calculating a charging current limit value based on the desired charging speed level and maximum and minimum allowable charging current values of the battery; a charge control step of: instructing a charge controller for the battery to charge the battery at an actual charge current value that is not higher than the charge current limit value.
