Description

power distribution device

A power distribution device, especially a power distribution device capable of controlling the output power of at least two charging ports in a standard distribution power supply mode or a first mode.

Any electronic device equipped with a rechargeable battery needs to be charged regularly, and most of the charging requires an adapter to convert AC alternating current into DC direct current to facilitate charging the rechargeable battery. With the development of technology, some adapters are equipped with at least two charging ports for charging at least two electronic devices at the same time. Furthermore, current adapters with at least two charging ports can only charge at least two electronic devices simultaneously in a fixed power distribution mode, but cannot flexibly change the power distribution mode.

Among them, the most common power distribution mode is to evenly distribute the charging power to at least two charging ports, so that the charging power given to each electronic device by each charging port will be consistent. However, if one of the at least two electronic devices that needs to be charged urgently needs to be charged quickly, the current adapter cannot give the electronic device that urgently needs to be charged a higher charging power than the other electronic device that is being charged. , that is, it is impossible to shorten the charging time of the electronic device that urgently needs to be charged according to the situation.

In addition, in the current adapters with at least two charging ports, each charging port is provided with a fixed power distribution, that is, one of the charging ports can perform fast charging, while the other charging port can only use normal charging power. However, if the number of electronic devices that require fast charging and the number of electronic devices that do not need fast charging are different from the originally designed power distribution scheme, the distribution of charging power cannot be flexibly used.

For example, suppose the adapter has 3 charging ports and can charge multiple electronic devices with a total wattage of 120 watts, one of the fast charging ports has a charging power of 60 watts, and the charging power of the two slow charging ports 30 watts each. However, among the 3 electronic devices that need to be charged, 2 have a need for fast charging, while the other has no urgent need for charging. But the adapter is limited by its fixed charging power allocation scheme, Only one of the electronic devices can be quickly charged at 60 watts, and the other two can only be charged slowly at 30 watts, which cannot meet the needs of two electronic devices for fast charging. Therefore, today's adapters cannot flexibly adjust the output power, and cannot efficiently and quickly charge electronic devices.

Referring to FIGS. 1 to 3 , a power distribution device of the present invention includes a housing 5 , a plug 10 , at least two charging ports 20 , a charging unit 30 and a processing unit 40 . The plug 10 and the at least two charging ports 20 are disposed on the housing 5 , and the charging unit 30 and the processing unit 40 are disposed in the housing 5 . The charging unit 30 is electrically connected to the at least two charging ports 20 and the plug 10 , and the processing unit 40 is electrically connected to the charging unit 30 . In a first embodiment, the at least two charging ports 20 are a first charging port 20A and a second charging port 20B.

As shown in FIG. 3 , the processing unit 40 determines whether a trigger signal is received ( S1 ). When the processing unit 40 does not receive the trigger signal, the processing unit 40 controls the charging unit 30 according to a standard distributed power supply mode (S3), and the charging unit 30 controls the output power of the at least two charging ports 20 correspondingly, When the processing unit 40 receives the trigger signal, the processing unit 40 controls the charging unit 30 according to a first mode (S2), and the charging unit 30 controls the output power of the at least two charging ports 20 accordingly.

In the first embodiment, the trigger signal comes from an electronic device electrically connected to the first charging port 20A or the second charging port 20B, and these electronic devices can be electrically connected to the first charging port 20A or the second charging port 20B through a transmission line. The second charging port 20B performs charging. For example, the electronic devices can generate the trigger signal by running an application program (APP), and transmit the trigger signal to the at least two charging ports 20 through the transmission line. When the charging unit 30 receives the trigger signal from the at least two charging ports 20 , the charging unit 30 forwards the trigger signal to the processing unit 40 . In other words, the processing unit 40 can receive the trigger signal from the first charging port 20A or the second charging port 20B through the charging unit 30 .

The processing unit 40 of the present invention is built with an internal data, and the internal data includes the control content of the standard distributed power supply mode. The standard distributed power supply mode is a commonly known charging mode, that is, the at least two charging ports 20 charge the electronic devices with a fixed maximum output power. When the processing unit 40 receives the trigger signal to control the charging unit 30 according to the first mode, the processing unit 40 can flexibly adjust the output power of the at least two charging ports 20 to increase the charging rate.

In the first embodiment, the first mode is a forced distribution power supply mode. In the forced distribution power supply mode, the processing unit 40 determines one of the at least two charging ports 20 to be a first priority charging port according to the trigger signal, and the processing unit 40 determines a first priority charging port according to a first priority charging port. The first required power controls the charging unit 30 to supply power to the first priority charging port with the first required power, and the processing unit 40 calculates a power according to a rated total power and the first required power of the first priority charging port. the remaining power, and control the charging unit 30 to supply power to the remaining charging ports with the remaining power.

When the processing unit 40 controls the charging unit 30 according to the first mode, the processing unit 40 determines one of the at least two charging ports 20 as the first priority charging port according to the trigger signal, such as the first charging port Port 20A. And the processing unit 40 receives at least two state signals corresponding to the at least two charging ports 20 through the charging unit 30, and determines the first required power of the first priority charging port according to the at least two state signals, and the processing unit 40 The charging unit 30 is controlled to supply power to the first charging port 20A according to the first required power. The processing unit 40 further calculates the remaining power according to the rated total power and the first required power, for example, the rated total power is subtracted from the first required power to obtain the remaining power, and then the processing unit 40 calculates the remaining power according to the remaining power The charging unit 30 is controlled to supply power to the second charging port 20B.

For example, the at least two status signals of the at least two charging ports 20, that is, a first status signal of the first charging port 20A and a second status signal of the second charging port 20B are derived from the first charging port 20B. The electronic devices connected to a charging port 20A and the second charging port 20B, these electronic devices generate the first state signal and the Second status signal. For example, these electronic devices will notify each charging port of its required charging power when connected, that is to say, the first status signal and the second status signal include the required charging power of each electronic device, and Each electronic device will notify the processing unit 40 of its required charging power through the first status signal and the second status signal.

In addition, logically speaking, the more power-deficient electronic devices will require a higher charging rate, therefore, in the first embodiment, when these electronic devices are connected to the at least two charging ports 20, the electronic devices The charging port connected to the electronic device with the lowest remaining power in the device will be correspondingly set as the first priority charging port to meet the charging demand of the electronic device that is short of power.

The processing unit 40 determines one of the at least two charging ports 20 as the first priority charging port according to the at least two state signals, and in the first embodiment, the processing unit 40 determines the first priority charging port A priority charging port is a charging port of the at least two charging ports 20 corresponding to the most power-deficient electronic device, that is, the charging port that most needs to be satisfied with its required output power.

Please refer to Table 1 below, in the standard distributed power supply mode, the maximum output power of the first charging port 20A is 60 watts (Watt; W), and the maximum output power of the second charging port 20B It is 30W. And the required power for charging the electronic device connected to the first charging port 20A is 90W, and the required power for charging the electronic device connected to the second charging port 20B is 30W. Assume that the rated total power is 120W, the first charging port 20A is the first priority charging port, the first required power is 90W, and the minimum output power is 10W. Therefore, in the standard distributed power supply mode, the maximum output power of the first charging port 20A is only 60W, which cannot be adjusted to the first required power of 90W, while the output power of the second charging port 20B is 30W. When the first mode is the forced distribution power supply mode, after receiving the trigger signal to execute the first mode, the processing unit 40 controls the first charging port 20A according to the first mode, and the first charging port The output power of 20A is increased from 60W to 90W, and the remaining power is calculated according to the rated total power and the first required power, that is, 120W-90W=30W, therefore, the remaining power is 30W, so the processing unit 40 controls the The output power of the second charging port 20B remains unchanged at 30W.

In a second embodiment, the first mode is an oversubscription power supply mode. In the over-allocation power supply mode, the processing unit 40 determines one of the at least two charging ports 20 as the first priority charging port according to the trigger signal, and the processing unit 40 determines according to the first priority charging port of the first priority charging port. The charging unit 30 is controlled by the first required power to supply power to the first priority charging port with the first required power, and the processing unit 40 controls the charging unit 30 according to a minimum output power of the remaining charging ports to use the minimum output power The output power supplies power to the remaining charging ports. Wherein, the minimum output power is set by the power distribution device to ensure that the connected electronic devices can be charged at a minimum, and the minimum output power is a built-in setting of the power distribution device. The minimum output power is usually 10W under current charging protocols.

For example, when the processing unit 40 controls the charging unit 30 according to the first mode, the processing unit 40 determines one of the at least two charging ports 20 as the first priority charging port according to the trigger signal, for example The first charging port 20A. And the processing unit 40 receives the at least two state signals corresponding to the at least two charging ports 20 through the charging unit 30, and determines the first required power of the first priority charging port according to the at least two state signals, and the processing unit 40 controls the charging unit 30 to supply power to the first charging port 20A according to the first required power. The processing unit 40 further determines the minimum output power of the other charging ports, such as the second charging port 20B, according to the at least two state signals, and then the processing unit 40 controls the charging unit 30 to charge the second charging port according to the minimum output power. The charging port 20B supplies power.

Please refer to Table 2 below, assuming that the rated total power is 120W, the first charging port 20A is the first priority charging port, and the first required power of the first priority charging port is 120W, and the other charging ports The minimum output power is 10W, the maximum output power of the first charging port 20A is 60W, and the maximum output power of the second charging port 20B is 30W. Therefore, in the standard distributed power supply mode, the maximum output power of the first charging port 20A is only 60W, which cannot be adjusted to the first required power of 120W, while the output power of the second charging port 20B is 30W. When the first mode is the over-allocation power supply mode, after receiving the trigger signal to execute the first mode, the processing unit 40 controls the first charging port 20A according to the first mode, and the first charging port The output power of 20A is increased from 60W to 120W, and the second charging port 20B is controlled according to the minimum output power, and the output power of the second charging port 20B is reduced from 30W to 10W.

Please refer to FIG. 4, in a third embodiment, when the processing unit 40 determines that one of the at least two charging ports 20 is the first priority charging port according to the trigger signal, the processing unit 40 is Further, the charging unit 30 receives at least two status signals corresponding to the at least two charging ports 20 , and the processing unit 40 determines the first required power of the first priority charging port according to the at least two status signals.

The processing unit 40 further judges whether the sum of the first required power and the minimum output power is less than or equal to the rated total power ( S11).

When the sum is less than or equal to the rated total power, the processing unit 40 controls the charging unit 30 according to the first mode (S2). In the third embodiment, the first mode is the forced distribution power supply mode. In the forced distribution power supply mode, the processing unit 40 controls the charging unit 30 to supply power to the first priority charging port with the first required power, and the processing unit 40 The first required power calculates the surplus power, and controls the charging unit 30 to supply power to the remaining charging ports with the surplus power. For example, the remaining power is calculated by subtracting the first required power from the rated total power.

When the sum is greater than the rated total power, the processing unit 40 controls the charging unit 30 according to a second mode (S21). In the third embodiment, the second mode is the over-allocation power supply mode, and in the over-allocation power supply mode, the processing unit 40 controls the charging unit 30 to charge the first priority charging port with the first required power power supply, and the processing unit 40 controls the charging unit 30 to supply power to the remaining charging ports with the lowest output power.

Please refer to Table 3 and Table 4 below, assuming that the rated total power is 120W, the first charging port 20A is the first priority charging port, and the first required power of the first priority charging port is 90W, and the rest The minimum output power of the charging port is 10W, the maximum output power of the first charging port 20A is 60W, and the maximum output power of the second charging port 20B is 30W. Therefore, in the standard distributed power supply mode, the maximum output power of the first charging port 20A is only 60W, which cannot be adjusted to the first required power of 90W, while the output power of the second charging port 20B is 30W. After the processing unit 40 receives the trigger signal, the processing unit 40 first determines whether the sum of the first required power and the minimum output power is less than or equal to the rated total power. When the sum is less than or equal to the rated total power, the processing unit 40 controls the charging unit 30 according to the first mode, otherwise, the processing unit 40 controls the charging unit 30 according to the second mode.

Assume that as shown in Table 3 below, the sum is 90W+10W=100W, which is less than the rated total power of 120W. Therefore, the processing unit 40 executes the first mode, and the first mode is the forced power supply mode. The processing unit 40 increases the output power of the first charging port 20A from 60W to 90W, and calculates the remaining power according to the rated total power and the first required power, that is, 120W-90W=30W, therefore, the remaining power is 30W, so the processing unit 40 controls the output power of the second charging port 20B to maintain 30W.

Assume that as shown in Table 4 below, the sum is 120W+10W=130W, which is greater than the rated total power of 90W. Therefore, the processing unit 40 is executing the second mode, and the second mode is the oversubscription power supply mode. The processing unit 40 increases the output power of the first charging port 20A from 60W to 120W, And according to the minimum output power, the second charging port 20B is controlled, and the output power of the second charging port 20B is lowered from 30W to 10W.

5 and 6, in a fourth embodiment, the at least two charging ports 20 include the first charging port 20A, the second charging port 20B and a third charging port 20C, respectively connected to the charging unit 30 . For example, the processing unit 40 determines according to the trigger signal that the first charging port 20A is the first priority charging port, the second charging port 20B is a second priority charging port, and the third charging port 20C is a A third priority charging port. And the processing unit 40 receives the first status signal corresponding to the first charging port 20A, the second status signal corresponding to the second charging port 20B, and a first status signal corresponding to the third charging port 20C through the charging unit 30 Three-state signal. And the processing unit 40 further determines the first required power of the first priority charging port according to the first state signal, determines a second minimum output power of the second priority charging port according to the second state signal, and determines the second minimum output power of the second priority charging port according to the The third state signal determines a third minimum output power of the third priority charging port. The processing unit 40 judges whether the sum of the first required power, the second minimum output power, and the third minimum output power is based on the first required power, the second minimum output power, and the third minimum output power less than or equal to the rated total power.

When the sum is less than or equal to the rated total power, the processing unit 40 controls the charging unit 30 according to the first mode. In the fourth embodiment, the first mode is the forced distribution power supply mode, and in the forced distribution power supply mode, the processing unit 40 controls the charging unit 30 to charge the first priority charging port with the first required power power supply, and the processing unit 40 controls the charging unit 30 to supply power to the third priority charging port with the third lowest output power, and the processing unit 40 according to the rated total power, the first A demand power and the third minimum output power calculate a surplus power, and control the charging unit 30 to supply power to the second priority charging port with the surplus power.

When the sum is greater than the rated total power, the processing unit 40 controls the charging unit 30 according to the second mode. The second mode is the over-allocation power supply mode, and in the over-allocation power supply mode, the processing unit 40 controls the charging unit 30 to supply power to the first priority charging port with the first required power, and the processing unit 40 controls The charging unit 30 supplies power to the second priority charging port with the second minimum output power, and the processing unit 40 controls the charging unit 30 to supply power to the third priority charging port with the third minimum output power.

For example, please refer to Table 5 and Table 6 below, in the standard distributed power supply mode, the maximum output power of the first charging port 20A is 60W, the maximum output power of the second charging port 20B is 30W, and The maximum output power of the third charging port 20C is 30W. The first charging port 20A is the first priority charging port, the second charging port 20B is the second priority charging port, and the third charging port 20C is the third priority charging port. The first to the third minimum output powers are all 10W.

Assume that as shown in Table 5 below, the first required power of the first charging port 20A is 90W, the second required power of the second charging port 20B is 60W, and the third required power of the third charging port 20C is 30W, the rated total power is 120W. The sum of the first required power, the second minimum output power, and the third minimum output power is 90W+10W+10W=110W, which is less than the rated total power of 120W. The processing unit 40 executes the first mode, and the first mode is the forced power distribution mode. The processing unit 40 increases the output power of the first charging port 20A from 60W to 90W according to the first required power, and lowers the output power of the third charging port 20C from 30W to 90W according to the third minimum output power. 10W. And the processing unit 40 calculates the remaining power according to the rated total power, the first required power calculation, and the third minimum output power, that is, 120W-90W-10W=20W, therefore, the remaining power is 20W, so the processing unit 40 controls the output power of the second charging port 20B to be reduced from 30W to 20W.

Assume that as shown in Table 6 below, the first required power of the first charging port 20A is 110W, the second required power of the second charging port 20B is 60W, and the third required power of the third charging port 20C is 30W, the rated total power is 120W. The sum of the first required power, the second minimum output power, and the third minimum output power is 110W+10W+10W=130W, which is greater than the rated total power of 120W. The processing unit 40 executes the second mode, and the second mode is the oversubscription power supply mode. The processing unit 40 increases the output power of the first charging port 20A from 60W to 110W according to the first required power, and reduces the output power of the second charging port 20B from 30W to 110W according to the second minimum output power. 10W, and the output power of the third charging port 20C is lowered from 30W to 10W according to the third minimum output power.

In a fifth embodiment, in the over-allocation power supply mode, the processing unit 40 determines one of the at least two charging ports 20 to be the first priority charging according to the trigger signal. mouth, and the processing unit 40 controls the charging unit 30 according to the first demand power of the first priority charging port, and supplies power to the first priority charging port with the first demand power, and the processing unit 40 The charging unit 30 is controlled according to a standard required power of the remaining charging ports, and the remaining charging ports are supplied with the standard required power.

For example, assuming that the rated total power is 120W, the first charging port 20A is the first priority charging port, the second charging port 20B is the second priority charging port, and the third charging port 20C is the third priority charging port. Priority charging port. And the first required power of the first priority charging port is 90W, the second required power of the second priority charging port is 60W, and the third required power of the third priority charging port is 10W. The minimum output powers of the first to the third priority charging ports are all 10W. The maximum output power of the first charging port 20A is 60W, the maximum output power of the second charging port 20B is 30W, and the maximum output power of the third charging port 20C is 30W. Therefore, in the standard distributed power supply mode, the output power of the first charging port 20A can only be 60W at most, which cannot be adjusted to the first required power of 90W, and the output power of the second charging port 20B and the third charging port 20C The output power is 30W and 10W respectively. When the first mode is the over-allocation power supply mode, after receiving the trigger signal to execute the first mode, the processing unit 40 controls the first charging port 20A according to the first mode, and the first charging port The output power of 20A is increased from 60W to 90W, and the second charging port 20B and the third charging port 20C are controlled according to the standard required power, and the output power of the second charging port 20B and the third charging port are maintained respectively It remains unchanged at 30W and 10W.

The above-mentioned first required power is the charging power required by the electronic device connected to the first priority charging port, for example, assuming that the electronic device connected to the first priority charging port is a notebook computer The charging power required by the device may be 90W. For example, if the electronic device connected to the first priority charging port is a smart phone, the required charging power may be 30W. As the electronic equipment changes, the first required power will also change. In addition, the rated total power is an output power threshold conservatively set by the power distribution device for safety, so that the power distribution device does not need to worry about overheating when charging within the rated total power. When the power distribution device exceeds the rated total power to charge the electronic devices, it should be noted that the temperature of the power distribution device may gradually increase with prolonged use. Therefore, when the power distribution device exceeds the rated total power to charge the electronic devices, it is necessary to periodically reduce the charging power to allow the power distribution device to dissipate heat sufficiently to maintain the normal operation of the power distribution device.

To make the power distribution device fully dissipate heat, a timing unit is set in the processing unit 40, and when the first mode is the over-allocation power supply mode, the timing unit of the processing unit 40 further limits the execution time of the over-allocation power supply mode That is, the timing unit of the processing unit 40 controls the charging unit 30 to operate in the over-allocation power supply mode in a manner that does not exceed a safe time at the longest. And when the time of executing the over-allocation power supply mode continues to exceed the safety time, the timing unit will generate an time-out signal, so that the processing unit 40 will return to control the charging unit 30 according to the standard allocation power supply mode. This ensures that the power distribution device can comply with safety regulations. For example, assuming that the rated total power is 100W, when the over-allocation power supply mode is executed, it will be over-subscribed to 120W for use. After about 1 hour, the temperature of the casing 5 will reach the temperature limit of the safety regulation, so the over-submission will be set during design. Only use less than 50 minutes to ensure compliance with safety regulations.

In addition, the processing unit 40 is further provided with an absolute total power upper limit. The processing unit 40 controls the charging unit 30 according to the absolute total power upper limit, so that the charging unit 30 controls the sum of all outputs of the at least two charging ports 20 in the over-allocation power supply mode to be less than or equal to the absolute total power upper limit. If in the over-allocation power supply mode, the rest of the charging ports other than the first priority charging port have used the minimum output power to charge these electronic devices, then the sum of all outputs of the first priority charging port is less than or equal to the Under the premise of the absolute total power upper limit, the output power of the first priority charging port is less than or equal to (the absolute total power upper limit-the sum of the minimum output powers of the remaining charging ports). The absolute total power upper limit is the absolute threshold of the output power of the power distribution device, that is, when the absolute total power is exceeded for charging, the output of the power distribution device may be in danger of excessive power consumption. In order to avoid hazards, the power distribution device must in any case be used within the absolute total power limit.
