As shown in fig. 1, an embodiment of the present application provides a method for devulcanizing a storage battery, including:
Acquiring a vehicle use state signal;
determining that the vehicle is in an unused state according to the vehicle use state signal;
and entering a devulcanization program based at least on the vehicle being in an unused state.
The embodiment of the application provides a storage battery devulcanization method. According to the method, a vehicle use state signal is acquired, and whether the vehicle is in an unused state or not can be determined according to the vehicle use state signal. When it is determined that the vehicle is not in use, a de-sulfurization procedure is entered based at least on the vehicle being in use. The method has the advantages that the storage battery does not need to be taken down, the storage battery can be devulcanized on the vehicle, and the devulcanization cost is reduced. And when the vehicle is in an unused state, a devulcanization procedure is carried out, so that the risks that the electronic components of the vehicle are possibly damaged or the normal work and use of the electronic components of the vehicle are influenced are avoided.
In the embodiment of the application, the storage battery is subjected to devulcanization on the vehicle. The Vehicle Control Unit (VCU) controls a DCDC (DC to DC Converter) to output pulse voltage to be applied to the storage battery for devulcanization.
In some embodiments, entering a devulcanization procedure comprises: the vehicle control unit VCU controls the step of the DCDC output voltage from the current voltage (the normal output voltage value, generally 14.5V) to the first voltage for a first duration. The VCU controls the DCDC output voltage to step to a second voltage for a second duration. And repeating the steps until the whole process is executed for the third time, and completing the devulcanization. Wherein the first voltage is lower than the second voltage. The first duration is greater than the second duration. The first time period may for example last 0.9s and the second time period may for example be 0.1 s. The first voltage and the second voltage are between the highest voltage of the storage battery and the highest voltage at which each controller on the vehicle can normally operate. The first voltage is near a maximum voltage of the battery. The maximum voltage of the battery is typically 12.3V, and the first voltage may be, for example, 12.5V. The second voltage is close to the highest voltage at which each controller on the automobile can normally work. The highest voltage at which the controllers on the vehicle can operate normally is 16V, and the second voltage may be, for example, 15.8V.
The third time period is the time period of the entire vulcanization procedure. The duration of the vulcanization program can be preset or can be set according to a setting instruction. Specific examples are illustrated in the following examples.
In the embodiment of the application, the vulcanization program can be divided into a plurality of types, and the parameters of different vulcanization programs can be different. For example, the duration of the vulcanization procedure varies, etc.
In some embodiments, entering a devulcanization procedure comprises: entering a first vulcanization procedure; or enter a second disulfide procedure. Wherein the duration of the first vulcanization procedure is less than the duration of the second vulcanization procedure. In the embodiments of the present application, at least two devulcanization procedures are included, such as a first vulcanization procedure and a second vulcanization procedure. The first and second vulcanization procedures are at least different in duration of the vulcanization procedure, the duration of the first vulcanization procedure being less than the duration of the second vulcanization procedure. Different vulcanization procedures can be entered according to different situations. For example, when the degree of vulcanization of the storage battery is high, the second vulcanization procedure is entered, and when the degree of vulcanization is low, or when the devulcanization is frequent, the first devulcanization procedure can be entered.
In some embodiments, entering a devulcanization procedure based at least on the vehicle being in an unused state may include: and entering a devulcanization procedure based on the DCDC being in a self-starting state and the vehicle being in an unused state.

entering a devulcanization procedure based at least on the vehicle being in an unused state, comprising:
and entering a devulcanization procedure based on the DCDC being in a self-starting state and the vehicle being in an unused state.
In the embodiment of the application, whether the vehicle is in the DCDC self-starting state or not can be determined. When the DCDC is in a self-starting state and the vehicle is in an unused state, a devulcanization procedure is entered. Since the DCDC is in a self-start state more, it can be the first devulcanization procedure with a shorter entry time.
Under certain conditions, the DCDC may start itself. The DCDC is a state common to the vehicle at the time of the self-start, and the start condition thereof is not particularly limited. For example, when the DCDC detects that the state of charge (SOC) of the battery reaches a set value, the DCDC self-starts to charge the battery. The set value may be, for example, 60%, and the DCDC starts up when the DCDC detects that the SOC of the battery is less than 60%. When the DCDC is started automatically, the DCDC sends an automatic starting signal to the VCU. In the embodiment of the application, the devulcanization program can be started when the DCDC is started, the VCU and the DCDC do not need to be started independently for devulcanization, and extra awakening of a vehicle is not increased. The devulcanization procedure can be entered every time the DCDC is started up, and a shorter time of devulcanization can be performed each time. For example, the devulcanization procedure is maintained for 30 min. The amount of power consumed is very little. Through accumulation, the storage battery can be kept in a healthy state, and the effect of prolonging the service life of the storage battery is achieved. The problem that the vulcanizing degree of the storage battery is too high, and the service life of the storage battery is influenced is avoided.

When the DCDC is started, the DCDC charges a storage battery. When the vulcanization is removed, the DCDC output is pulse voltage, so that the charging of the storage battery is influenced. Therefore, the charging state of the storage battery is determined in the embodiment of the application, and whether to enter the devulcanization is determined according to the charging state of the storage battery.

when the output current of the DCDC is less than a first threshold, the state of charge of the storage battery is determined to be a full charge state.
In the embodiment of the application, whether the charging state of the storage battery is the full charging state is determined through the output current of the DCDC. When the output current of the DCDC is less than a first threshold, the state of charge of the storage battery is determined to be a full charge state. In general, DCDC is self-started, and the output current of DCDC is kept at a constant value during the charging process of the storage battery. On the basis of this, a first threshold value may be set, and when it is lower than the first threshold value, it is possible to determine that the state of charge of the storage battery is a full charge state. The first threshold may be determined based on recent historical data, and thus, the first threshold may be different each time, and the first threshold determined based on recent historical data replaces the original value.
Of course, the first threshold may also be a fixed value. Each time compared to the fixed value. For example, the first threshold may be 1A. And when the output current of the DCDC is monitored to be less than 1A, determining that the charging state of the storage battery is a full-charge state. Otherwise, it is determined that the battery is still in a charged state.

When the power battery is charged each time, the devulcanization procedure can be carried out, and the devulcanization can be carried out for a short time each time. For example, the devulcanization procedure is maintained for 30 min. The electric quantity consumed at this moment is the electric quantity of the charging pile, the electric quantity of the power battery is not influenced, and the consumed electric quantity is very little. Through accumulation, the storage battery can be kept in a healthy state, and the effect of prolonging the service life of the storage battery is achieved.
