FIG. 1A is a schematic functional block diagram of a charging device according to an embodiment of the invention. Please refer to Figure 1A. A charging device 1 is electrically connected to a vehicle generator 9 and a battery 8. The charging device 1 includes a power control module 12 and an arithmetic control module 10. In practice, the power control module 12 is electrically connected to the vehicle generator 9. The arithmetic control module 10 is electrically connected to the power control module 12, the vehicle generator 9 and the battery 8. The battery 8 is electrically connected to the in-vehicle system 6 through a power switch 7. The in-vehicle system 6 is, for example, a car, a locomotive or other means of transport. This embodiment does not limit the aspect of the charging device 1 and the in-vehicle system 6.

In detail, the operation control module 10 includes a detecting unit 100 and a power supply. The unit 102, a processing unit 104, a driving unit 106, a phase detecting unit 108 and a temperature unit 110. In practice, the detecting unit 100 is electrically connected to the vehicle generator 9 and the power starting unit 102. The power start unit 102 is electrically connected to the power control module 12 and the battery 8, the detecting unit 100, the processing unit 104, the driving unit 106, the phase detecting unit 108, and the temperature unit 110. The processing unit 104 is electrically connected to the driving unit 106, the phase detecting unit 108, and the temperature unit 110. The driving unit 106 is electrically connected to the power control module 12 and the processing unit 104. The phase detecting unit 108 is electrically connected to the vehicle generator 9 and the processing unit 104.

The processing unit 104 normalizes the phase signal to obtain a normalized phase signal, and the processing unit 104 obtains an output voltage of the power control module 12. The processing unit 104 calculates a voltage difference between a predetermined voltage and an output voltage. The processing unit 104 performs an operation according to the normalized phase signal, the voltage difference, and a pre-cycle trigger phase, so that the processing unit 104 obtains a trigger phase, and the processing unit 104 uses the trigger phase as a trigger signal, and outputs a trigger signal to the driver. Unit 106. The driving unit 106 drives the power control module 12 according to the trigger signal, so that the power control module 12 converts the alternating current of the vehicle generator 9 into a charging current, and outputs a charging current to charge the battery 8.

Next, the detecting unit 100 is implemented by, for example, a detecting circuit or a state detecting circuit. The detecting unit 100 is configured to detect a voltage state of the vehicle generator 9 . The voltage state is, for example, a non-zero voltage or a voltage level. For example, the detecting unit 100 detects whether the vehicle generator 9 has a voltage or detects whether the voltage of the vehicle generator 9 exceeds a preset value. When the detecting unit 100 detects a voltage state of the vehicle generator 9, the detecting unit 100 outputs a detecting signal to the power starting unit 102. That is to say, when the vehicle generator 9 has a voltage or the voltage exceeds a preset value, the detecting unit 100 outputs a detection signal to the power starting unit 102.

The power start unit 102 is realized, for example, by a power start circuit, a power processing and start circuit, or a condition start circuit. The power activation unit 102 of the present embodiment activates each unit in the arithmetic control module 10 under two conditions. In other embodiments The power start unit 102 can also activate each unit in the arithmetic control module 10 under one condition or multiple conditions. This embodiment does not limit the operation of the power source starting unit 102.

When the power start unit 102 determines that a battery voltage of the battery 8 is present, the power start unit 102 starts the operation by the instruction processing unit 104, the driving unit 106, the phase detecting unit 108, and the temperature unit 110 according to the detection signal and the battery voltage. In practice, when the voltage of one of the vehicle generator 9 and the battery 8 does not exist, the power starting unit 102 does not start the operation of each unit in the arithmetic control module 10, thereby achieving energy saving, power saving and environmental protection functions. .

When the voltages of the vehicle generator 9 and the battery 8 are both present, the power source activation unit 102 will activate each unit in the arithmetic control module 10. For example, after the locomotive is parked for a period of time and not used, if the battery 8 still has sufficient power to drive the engine and the vehicle generator 9, the power starting unit 102 according to the voltage of the vehicle generator 9 and the battery 8 The operations of each unit such as the processing unit 104, the driving unit 106, the phase detecting unit 108, and the temperature unit 110 are started.

The phase detecting unit 108 is implemented, for example, by a phase detecting circuit. The phase detecting unit 108 is configured to detect a phase signal of the vehicle generator 9 . In practice, the phase signal is, for example, a single-phase signal, a two-phase signal, a three-phase signal, or a multi-phase signal. This embodiment does not limit the aspect of the phase signal. The phase detecting unit 108 outputs a phase signal detecting the vehicle generator 9 to the processing unit 104.

Processing unit 104 is implemented, for example, by a microprocessor, microcontroller, arithmetic unit, or other processing circuit. The processing unit 104 is configured to receive and calculate signals output by the units. This embodiment does not limit the aspect of the processing unit 104. The processing unit 104 receives the phase signal and normalizes the phase signal to obtain a normalized phase signal (Pn), and stores the normalized phase signal in the register. When the processing unit 104 determines that the phase signal is in an abnormal state, the processing unit 104 stops controlling the trigger driving unit 106 to stop the power control module 12 from switching the alternating current of the vehicle generator 9 to a charging current.

In addition, the processing unit 104 can also obtain the output voltage of the power control module 12 through the feedback circuit, and the processing unit 104 calculates a voltage difference between the preset voltage and the output voltage. Thereafter, the processing unit 104 performs an operation according to the normalized phase signal, the voltage difference, and a pre-cycle trigger phase, so that the processing unit 104 obtains a trigger phase, and the processing unit 104 uses the trigger phase as a trigger signal, and outputs a trigger signal. The drive unit 106 is provided. The normalized phase signal, the voltage difference value, and the pre-cycle trigger phase are transmitted through a fuzzy control operation program of the processing unit 104 to calculate a trigger phase.

The driving unit 106 is, for example, a driving circuit of a driving circuit, a trigger driving circuit, an SCR driving circuit, or other transistor switches. This embodiment does not limit the aspect of the drive unit 106. The driving unit 106 controls the power control module 12 according to the trigger signal, so that the power control module 12 converts the alternating current of the vehicle generator 9 into a charging current, and outputs a charging current to charge the battery 8.

It is worth mentioning that when the voltage difference is smaller and positive, the processing unit 104 delays the phase of the control trigger signal, so that the output voltage gradually approaches the preset voltage, thereby achieving the function of voltage stabilization. Conversely, when the voltage difference is larger and is negative, the processing unit 104 advances the phase of the control trigger signal so that the output voltage gradually approaches the preset voltage, thereby achieving the function of voltage stabilization. This embodiment does not limit the operation of the processing unit 104 according to the voltage difference.

The temperature unit 110 is implemented, for example, by a temperature detecting circuit, a temperature-voltage converting circuit, or other temperature detecting circuit. The temperature unit 110 is configured to detect a temperature signal of the operation control module 10. For example, the temperature unit 110 is configured to detect the temperature of one or a combination of the processing unit 104, the driving unit 106, the phase detecting unit 108, the detecting unit 100, and the power starting unit 102, whereby the temperature unit 110 outputs a temperature signal to the processing unit. 104, and the processing unit 104 adjusts the output magnitude of the charging current according to the temperature signal.

The processing unit 104 determines whether the temperature signal exceeds a predetermined temperature. If the result of the determination is yes, the processing unit 104 delays the trigger phase of the driving unit 106 to decrease The power control module 12 converts the alternating current of the vehicle generator 9 into a charging current, and outputs the regulated charging current to charge the battery 8. If the determination result is no, the processing unit 104 outputs a trigger signal to the driving unit 106, and the driving unit 106 controls the power control module 12 according to the trigger signal, so that the power control module 12 converts the alternating current of the vehicle generator 9 into a charging current. And outputting a charging current to charge the battery 8.

It should be noted that when the temperature of the arithmetic control module 10 obtained by the temperature unit 110 is higher, the processing unit 104 delays the trigger phase of the driving unit 106, thereby reducing the output of the charging current by the power control module 12. On the contrary, when the temperature of the arithmetic control module 10 obtained by the temperature unit 110 is lower, the processing unit 104 drives the trigger phase of the unit 106 earlier, thereby boosting the output of the charging current by the power control module 12.

In other words, the higher the temperature of the arithmetic control module 10 is, the smaller the output of the power control module 12 is, thereby protecting the units in the arithmetic control module 10. On the contrary, the lower the temperature of the arithmetic control module 10 is, the larger the output of the power control module 12 is, thereby increasing the output power of the power control module 12. This embodiment does not limit the operation of the arithmetic control module 10 and the power control module 12.

It is worth noting that the general control unit establishes a preset parameter table to control the driving of the general drive unit according to different characteristics and different phase sequence of the vehicle generator 9 . However, the processing unit 104 of the present embodiment does not need to establish a preset parameter table to control the driving of the driving unit 106. In this embodiment, the phase angle with closed loop control and the fuzzy logic program are used, and the vehicle generator 9 with different characteristics and different phase sequences can be widely used without The parameter table is readjusted or preset, thereby improving the usability of the charging device 1.

1B is a circuit diagram of a power control module in accordance with an embodiment of the present invention. Please refer to FIG. 1B and FIG. 1A. The power control module 12 is, for example, a three-phase rectifier circuit or a single-phase rectifier circuit. In practice, the rectifier circuit is, for example, a full bridge or a half bridge The flow circuit does not limit the aspect of the rectifier circuit in this embodiment. When the AC power source passes through the rectifier circuit to obtain a pulsating DC, the pulsating DC is used as the input voltage for supplying the battery 8. Furthermore, the pulsating direct current can be a full-wave or a half-wave pulsating direct current.

In addition, this embodiment is described by six silicon-controlled rectifiers (SCRs). The six step-controlled rectifier switches are electrically connected to the driving unit 106. In other embodiments, for example, a three-phase power rectifier circuit composed of three voltage-controlled rectifier switches and three diodes, or a single-phase power rectifier circuit composed of four voltage-controlled rectifier switches. This embodiment does not limit the aspect of the power control module 12.

2 is a functional block diagram of a charging device according to another embodiment of the present invention. Please refer to Figure 2. The charging device 1a in FIG. 2 is similar in structure to the charging device 1 in FIG. 1, and the same elements that are included in the following will be denoted by the same reference numerals. The difference between the charging devices 1a and 1 is that the computing control module 10 further includes: a trigger level generating unit 112, a noise suppressing unit 118, a detecting and protecting unit 114, a feedback unit 116, and a data transmission unit. 120.

The trigger level generating unit 112 is, for example, a trigger level generating circuit. The trigger level generating unit 112 is electrically connected to the vehicle generator 9 and the driving unit 106. In practice, the trigger level generating unit 112 is configured to generate a one-level voltage and output the level voltage to the driving unit 106, whereby the driving unit 106 converts the received trigger signal into the driving unit 106 according to the level voltage. Acceptable signal. The drive unit 106 thus drives the power control module 12 to convert the alternating current into a charging current. This embodiment does not limit the operational aspect of the trigger level generating unit 112.

The noise suppression unit 118 is implemented, for example, by a noise suppression circuit or a filter circuit. The noise suppression unit 118 is electrically connected to the power control module 12 and the driving unit 106. The noise suppression unit 118 is configured to suppress high and low frequency noise generated by the power control module 12 during switching, reduce electromagnetic interference and external noise, and prevent the driving unit 106 from being interfered.

The detection protection unit 114 transmits an open circuit detection and a surge control circuit, for example, an abnormality. Detection and protection circuits are implemented. The detection protection unit 114 is electrically connected to the power control module 12, the power activation unit 102, and the processing unit 104, and the detection protection unit 114 is configured to detect the open state of the battery 8, and to prevent an overvoltage surge generated instantaneously when the battery 8 is opened. . This embodiment does not limit the aspect of detecting the protection unit 114.

For example, battery 8 is out of the circuit system if it is not expected. For example, when the positive and negative terminals of the battery 8 are loose or detached, the detecting and protecting unit 114 can detect the condition that the positive and negative terminals of the battery 8 are loose or detached, thereby detecting that the protection unit 114 can prevent the charging current from flowing instantaneously into the circuit, and other devices. Or equipment.

The feedback unit 116 is, for example, a voltage division feedback circuit, an output voltage division feedback circuit, a battery voltage feedback circuit, or other feedback circuit. The feedback unit 116 is electrically connected to the power activation unit 102 and the processing unit 104. In practice, the feedback unit 116 obtains the output voltage of the power control module 12 via the power activation unit 102, and divides the output voltage to be fed back to the processing unit 104, whereby the processing unit 104 can obtain the output voltage.

The data transmission unit 120 is electrically connected to the processing unit 104. In practice, the data transfer unit 120 is, for example, an I/O PORT, a USB port, or other port. This embodiment does not limit the aspect of the data transmission unit 120. The arithmetic control module 10 transmits the internal data or receives the external data through the data transmission unit 120. For example, the user can electrically connect the data transmission unit 120 through an external device, thereby reading internal data of the processing unit 104, such as current, voltage, or temperature.

In addition to the above differences, those skilled in the art should know that the operation portion of the present embodiment is substantially equivalent to the foregoing embodiment, and those skilled in the art having a reference to the present embodiment and the above differences should be easily Inferred, so I won't go into details here.

3 is a flow chart of a charging method according to another embodiment of the present invention. Please refer to Figure 3. A charging method comprising the following steps:

In step S301, the processing unit initializes. In practice, when the voltage state of any of the vehicle generator and the battery is zero voltage or the voltage does not exist, the power is turned on. The unit does not initiate the operation of the processing unit. On the other hand, when the voltage state of the vehicle generator and the battery is not zero voltage, that is, when the voltage of the vehicle generator and the battery are both present, the power start unit starts the operation of each unit in the arithmetic control module.

Wherein, when the processing unit starts to operate, the processing unit resets, and the processing unit obtains the preset voltage value and the preset temperature value. Of course, those skilled in the art can freely design preset voltage values and preset temperature values according to the physical state of the operation control module, the processing chip, or the control chip.

In step S303, the processing unit acquires a phase signal and samples the phase signal. In practice, the phase detecting unit detects the phase signal of the vehicle generator and transmits the phase signal to the processing unit, whereby the processing unit reads the phase signal and samples the phase signal. After the sampled phase signals are compared and sorted, the process proceeds to the determination in step S305.

In step S305, it is determined whether the state of each phase signal after sampling is normal. If the answer of step S305 is YES, the process proceeds to step S307, and the processing unit normalizes the sampled phase signals to obtain a normalized phase signal. On the other hand, if the decision result in the step S305 is NO, the process proceeds to a step S308, the vehicle generator is in an abnormal state, and the drive unit prohibits the triggering of the power control module. That is to say, the processing unit does not output a trigger signal to the driving unit, and the driving unit does not drive the power control module to operate.

In step S309, the normalized phase signal is stored in the temporary memory. Next, in step S311, an output voltage is obtained, and a voltage difference between a predetermined voltage and an output voltage is calculated. In practice, the preset voltage can be designed according to the physical characteristics of one or a combination of the power control module and the battery. The preset voltage is used as a reference for supplying the current or the supply voltage in a regulated manner. Moreover, the present embodiment compares the preset voltage with the output voltage to stably control the output of the supply current or the supply voltage. The supply current or the supply voltage is a current or voltage supplied to the battery by the vehicle generator through the rectification circuit.

In step S313, the normalized phase signal, the voltage difference, and a pre-cycle are touched. The phase input fuzzy control calculation program is used for calculation. In practice, the fuzzy control calculation program calculates the normalized phase signal, the voltage difference, and a pre-cycle trigger phase by using a continuous asymptotic algorithm or other algorithms, thereby obtaining a better trigger. Phase. The fuzzy control calculation program is, for example, a Fuzzy Tech Module. This embodiment does not limit the aspect of the fuzzy control arithmetic program.

In step S315, the trigger phase of the driving unit is obtained. In practice, after the processing obtains the trigger phase of the control driving unit, the trigger phase is stored in the register to perform step S317. The processing unit uses the trigger phase as a trigger signal and outputs a trigger signal to control the driving unit.

In step S317, the temperature signal of the arithmetic control module is obtained. In practice, the temperature unit can obtain the temperature of each unit in the arithmetic control module, and convert the temperature into a voltage type or other type of temperature signal. And the temperature unit will transmit the temperature signal to the processing unit.

In step S319, it is determined whether the temperature signal exceeds a preset temperature. If the result of the determination in step S319 is YES, then in step S321, the trigger phase of the drive unit is delayed, and the trigger phase in the register is changed. In practice, the trigger phase of the delay driving unit is used to delay driving or turning on the power control module, so that the power control module delays the output charging current, thereby reducing the charging current, thereby reducing the temperature of the computing control module. Therefore, this embodiment can avoid the situation that the arithmetic control module is burned or damaged due to overheating or overheating.

In other embodiments, the preset temperature can also be achieved by a preset temperature range. The preset temperature range is, for example, between the preset upper limit temperature and the preset lower limit temperature. The preset upper limit temperature is greater than the preset lower limit temperature. When the temperature signal exceeds the preset upper limit temperature, the driving unit may delay driving the power control module to cause the power control module to lower the output of the charging current. Conversely, when the temperature signal is lower than the preset lower limit temperature, the driving unit can drive the power control module early to enable the power control module to increase the output of the charging current.

If the result of the determination in step S319 is NO, then in step S323, a touch is output. The signal is sent to the drive unit to cause the drive unit to drive the operation of the power control module, thereby outputting a charging current to the battery. In practice, the temperature of the arithmetic control module in this embodiment will affect the output of the charging current. At higher temperatures, assuming that the charging current becomes larger, the temperature will continue to climb upwards, thereby damaging or damaging the arithmetic control module. Therefore, in the present embodiment, when the temperature is higher, the phase of the driving unit is delayed to lower the output of the charging current, so the temperature will be lowered, thereby protecting the arithmetic control module.

In step S325, it is determined whether the battery is in an open state. If the result of the determination in step S325 is YES, then in step S327, the detection protection unit is activated. And in step S329, the circuit operation of the charging device is stopped. In practice, if the battery is disconnected from the circuit system in an unexpected situation, for example, the connector of the electrical connection battery is loose or detached, the embodiment will start the operation of detecting the protection unit to prevent the glitch, thereby instantaneously protecting the vehicle. system.

In step S331, it is determined whether the battery is reconnected. If the decision result in the step S331 is YES, the process returns to the step S301. That is to say, after the battery is reconnected, the processing unit will re-execute the process and judgment of steps S301 to S331. If the decision result in the step S331 is NO, the process returns to the step S329 to stop the circuit operation of the charging device.

It should be noted that in other embodiments, steps S317-S321 may be omitted, or steps S325-S331 may be omitted, or steps S317-S331 may be omitted. The steps S317 to S321 are omitted to omit the determination flow of the temperature of the detection operation control module, and the steps S325 to S331 are omitted to omit the determination flow of detecting whether the battery is in an open state. Of course, the processing unit of the present embodiment can be controlled to drive the driving unit by omitting steps S317 to S331. Those skilled in the art can freely design the step flow of steps S301 to S331.

In summary, the present invention is a charging device that transmits a phase control design and obtains a plurality of operational parameter values to calculate a trigger phase, and the processing unit controls the driving unit through a trigger phase to drive the driving unit to drive power control. The module converts the alternating current of the vehicle generator into a charging current, thereby stably charging the battery. In addition, this embodiment adopts phase detection closed loop control (Phase angle with closed) Loop control) and fuzzy logic program can be used in a wide range of vehicle generators with different characteristics and different phase sequence outlets without re-adjusting or presetting the parameter list.
