Mobile power unit

The present invention relates to a power supply device, and more particularly to a mobile power supply device.

Thanks to advances in technology, electronic devices such as smart phones or tablets have become quite popular, and the electronic devices are mainly powered by built-in batteries. However, considering the size and weight of the electronic device, the built-in battery usually cannot provide sufficient power, so when the user uses it outdoors, it also carries the mobile power to supplement the electronic device power at any time.

At present, the common mobile power source on the market mainly consists of a casing, a charging circuit and a battery, and usually a plurality of ports are provided on the casing for supplementing power with the utility power or connecting to the electronic device to supply power to the electronic device. However, after the power stored in the mobile power source is used, the user still needs to find a commercial power outlet that can provide power to continue to supplement the power. That is to say, the conventional mobile power supply can only supplement the power through a single power source, and it is still limited in use. Therefore, the design of the conventional mobile power supply needs to be improved.

Therefore, the purpose of the novel is to provide a kind of communication A power supply unit that supplements power with a power source or a DC power source.

Therefore, the new mobile power supply device can be electrically connected to a mains socket or a solar power generating unit. The mobile power supply device comprises: a housing unit, a power storage unit, an AC charging unit, and a DC charging unit. The housing unit includes a housing, an AC charging port disposed on the housing and electrically connectable to the mains socket, and a DC charging port disposed on the housing and electrically connected to the solar power generating unit. The power storage unit is mounted in the housing. The AC charging unit is mounted in the housing, and includes an AC power conversion module electrically connected to the AC charging port and converting an AC power into a DC charging power capable of charging the power storage unit, and limiting the A first charging protection module for DC charging power. The DC charging unit is mounted in the casing, and includes a DC power conversion module electrically connected to the DC charging port and converting the DC power generated by the solar power generating unit into a DC charging power capable of charging the power storage unit. And a second charging protection module that limits the DC charging power.

The effect of the novel is that the design of the above components enables the present invention to supplement the power through the mains socket. When used outdoors, the solar power generation unit can be used to supplement the power, which is quite convenient and practical. In addition, the first charging protection module and the second charging protection module can also protect the power storage unit to avoid overcharging of the power storage unit, and further extend the service life of the power storage unit.

Further, the number of the DC power supply ports 24 is not limited to three, and may be two or more when implemented. Of course, the housing unit 2 can also include only one DC power supply port 24.

The electric storage unit 3 of the present embodiment is composed of a plurality of battery strings not shown in parallel, but the series and parallel connection of the storage batteries are generally known and will not be described here. Further, the positive electrode of the electric storage unit 3 is connected to one of the ports 25, and the negative electrode is connected to the other of the connecting portions 25.

The AC charging unit 4 includes an AC power conversion module 41 electrically connected to the AC charging port 22, and a first charging protection module 42 electrically connected to the AC power conversion module 41 and the power storage unit 3. The AC power conversion module 41 can convert the AC power of the commercial power into a DC charging power that can charge the power storage unit 3. The first charging protection module 42 can limit the DC charging power according to the voltage value of the power storage unit 3. In the present embodiment, the AC sub-modulation module 41 is an AC/DC conversion circuit.

At this time, the DC power generated by the solar power generation unit 12 is first converted by the DC power conversion module 51 to generate the DC charging power, and the DC charging power can directly charge the power storage unit 3. However, during the charging process, the second charging protection module 52 continuously detects the voltage of the power storage unit 3, and when the second charging is guaranteed When the protection module 52 detects that the power storage unit 3 is full (for example, 4.25 V), the DC power module 51 is immediately stopped to charge the power storage unit 3, thereby achieving the effect of overcharge protection.

Similarly, when charging indoors, the power storage unit 3 is supplemented with power by the commercial power, and the AC power conversion module 41 can convert the AC power supplied from the commercial power into the DC power to charge the power storage unit 3. Of course, during the charging process, the first charging protection module 42 continuously detects the voltage of the power storage unit 3. Therefore, when the power storage unit 3 is fully charged, the first charging protection module 42 immediately stops the alternating current change. The electric module 41 charges the electric storage unit 3 to achieve the effect of overcharge protection.

The discharge protection module 61 can continuously detect the voltage of the power storage unit 3, and when the power of the power storage unit 3 is about to be exhausted (for example, 2.35V), the discharge protection module 61 immediately stops the power storage unit 3 to The electronic device 13 supplies power to prevent the power storage unit 3 from being damaged due to excessive discharge. In addition, if there is a short circuit in the power supply process, the voltage of the power storage unit 3 drops rapidly and is much lower than 2.35V due to the short circuit. At this time, the discharge protection module 61 also operates, and the power storage unit 3 can be immediately stopped. powered by.

It is worth mentioning that the new mobile power supply device can be connected in series or in parallel with one or more mobile power sources via the ports 25 . Referring to FIG. 3, when connected in parallel, for example, one conductive line 9 can be used to respectively connect two connection ports 25 representing the positive electrode, and then another conductive line 9 is respectively connected to represent the negative electrode.
