DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] In order to solve the technical problem that existing equipment cannot be charged using various power sources, the present invention provides a multi-mode power charging system that can use not only standard alternating current, i.e., city power, but also non-standard alternating current and direct current, and can provide charging services in various environments.

[0020] See also Figure 1 and Figure 2 , Figure 1 is a schematic diagram of a multi-mode power supply charging system provided by an embodiment of the present invention; Figure 2 It is a structural schematic diagram of a multi-mode power supply charging system provided in an embodiment of the present invention. Figure 1 The solid line indicates electrical connection, and the dotted line indicates signal connection. The multi-mode power supply charging system includes: an input unit 1 , an output unit 2 and a temperature control unit 3 .

[0021] The input unit 1 is used to connect to an external power supply and convert the current provided by the external power supply into a current of required specifications. The input unit 1 includes a DC interface 11, a standard AC interface 12, a non-standard AC interface 13, a multi-mode inverter module 14 and a rectifier module 15. The DC interface 11 and the non-standard AC interface 13 are electrically connected to the rectifier module 15 via the multi-mode inverter module 14, and the standard AC module 12 is directly electrically connected to the rectifier module 15.

[0022] It is easy to understand that in some embodiments, the input unit 1 may also include other types of special interfaces 16 for connecting to a specific type of power supply.

[0023] The DC interface 11 is used to connect a DC power supply, and the standard AC interface 12 is used to connect a standard AC power supply, that is, the mains. The non-standard AC interface is used to connect a non-standard AC power supply other than the mains, such as AC power with unstable voltage generated by a small gasoline or diesel generator. The multi-mode inverter module 14 is used to invert DC power and non-standard AC power into high-quality single-phase industrial frequency AC power (AC230V) for use. The rectifier module 15 then rectifies the single-phase industrial frequency AC power into the DC power required by the rechargeable battery for charging the output unit 2. The rectifier module 15 can use an integrated rectifier module with multiple voltage outputs, or it can use multiple rectifier modules with different voltage outputs separately.

[0024] In this embodiment, the DC input range is 9V to 60V, and the AC input range is 90V to 264V.

[0025] The output unit 2 is electrically connected to the rectifier module 15 , and the output unit 2 can be connected to the battery 9 to charge the battery.

[0026] The temperature control unit 3 is also electrically connected to the rectifier module 15, and is powered by the rectifier module 15 to regulate the temperature of the battery 9. The battery 9 is heated when the temperature is lower than or equal to the low temperature threshold, and is cooled when the temperature is higher than or equal to the high temperature threshold, so that the temperature of the battery 9 is maintained between the low temperature threshold and the high temperature threshold, that is, within the temperature range most suitable for charging.

[0027] In some embodiments, the output unit 2 includes one or more of a USB output port 21, a fast charge output port 22, and a battery charger 23, which are respectively used to charge different batteries and electrical devices, such as a 12V-17 lithium battery with a nominal value of 14.8V±0.4V, a 24V-3 lithium battery with a nominal value of 25.9V±0.7V, and a 18650 rechargeable battery.

[0028] It is easy to understand that in other embodiments, the output unit 2 may also include other types of output ports or chargers to meet the charging needs of more devices. When the output port or charger is charging, the rectifier module 15 can rectify the single-phase industrial frequency AC power into the DC power of the specification required by the connected battery or electrical equipment, so as to smoothly charge.

[0029] In some embodiments, the temperature control unit 3 includes an openable charging box 31, a heating device 32 and a temperature measuring device 33. The output unit 2, the heating device 32 and the temperature measuring device 33 are all arranged in the charging box 31, and the heating device 32 and the temperature measuring device 33 are respectively electrically connected to the rectifier module 15, and the rectifier module 15 supplies power to them. When charging, the battery 9 is connected to the corresponding charging port or charger in the output unit 2 and placed in the charging box 31. The heating device 32 is used to heat the battery 9 and improve the charging performance of the battery 9 in a low temperature environment. The temperature measuring device 33 is used to measure the temperature of the battery 9 and provide data support for the regulation of the heating device 32 so that the temperature of the battery 9 is kept within the temperature range most suitable for charging.

[0030] In some embodiments, the charging box 31 includes a box body 311, a partition 312, a box cover 313 and a thermal insulation layer 314. The partition 312 is arranged in the box body 311 and fixedly connected to the box body 311, and the partition 312 separates the charging chamber in the box body 311. The box cover 313 is detachably connected or movably connected to the box body 311 to close or open the charging chamber. The connection method can adopt common connection methods such as slides, hinges, and buckles, and a lock can also be provided to lock the box cover 313 and the box body 311. The thermal insulation layer 314 at least partially covers the inner wall of the charging chamber. Obviously, the thermal insulation layer 314 covers the inner wall of the charging chamber as much as possible, which can improve the thermal insulation performance and the heating efficiency. The heating device 32 and the temperature measuring device 33 are arranged in the charging chamber for heating and measuring the temperature of the battery.

[0031] In some embodiments, the partition 312 also separates the equipment cavity in the box 311, the multi-mode inverter module 14 and the rectifier module 15 are arranged in the equipment cavity, and the DC interface 11, the standard AC interface 12 and the non-standard AC interface 13 are arranged on the outer surface of the box 311 to facilitate connection with an external power supply. The various components of the system are arranged in the box 311, which can improve the portability of the system and is suitable for use in complex outdoor environments.

[0032] In some embodiments, the charging box 31 also includes a safety plate 315, which is arranged in the charging cavity and fixedly connected to the box body 311 and / or the partition 312. The safety plate 315 separates the inner cavity and the outer cavity in the charging cavity. The heating device 32 is arranged in the inner cavity and does not contact the safety plate 315. The output unit 2 is arranged in the outer cavity. The heating device 32 and the output unit 2 are separated by the safety plate 315 to avoid accidentally touching the heating device 32 and getting burned when taking and placing the battery. A through hole for air circulation can be formed on the safety plate 315 to facilitate heating of the battery 9.

[0033] In this embodiment, the heating device 32 may use a heating wire or a thermocouple to provide heat. The temperature measuring device 33 may use an infrared thermometer, which is arranged toward the output unit 2, so as to measure the temperature of the battery 9 installed on the output unit 2. In other embodiments, other types of heating devices and temperature measuring devices may also be used, as long as the functions of heating and temperature measurement can be achieved.

[0034] In some embodiments, the charging box 31 has a through hole connecting the charging cavity and the outside, and the temperature control unit 3 further includes a fan 34, which is disposed at the through hole and electrically connected to the rectifier module 15. The rectifier module 15 supplies power to the fan 34, which is used to cool the charging cavity to prevent the battery 9 from being overheated.

[0035] In some embodiments, the temperature control unit 3 further includes a controller 35, which is disposed in the equipment cavity and electrically connected to the rectifier module 15. The temperature measuring device 33 is connected to the controller 35 for signal transmission, and the controller 35 is also connected to the heating device 32 and the fan 34 for signal control. The temperature measuring device 33 transmits the temperature data of the battery 9 to the controller 35, and the controller 35 controls the heating device 32 or the fan 34 to work according to the temperature data, so as to heat or cool the battery 9 to keep the temperature of the battery 9 within a suitable range.

[0036] In some embodiments, the multi-mode power supply charging system further includes an electronically controlled switch 4, the output unit 2 is electrically connected to the rectifier unit 15 via the electronically controlled switch 4, and the controller 35 is also connected to the electronically controlled switch 4 for signal control. When the temperature of the battery 9 is not within a temperature range suitable for charging, that is, the temperature is lower than a low temperature threshold or higher than a high temperature threshold, the controller 35 can control the electronically controlled switch 4 to disconnect. Although the battery 9 is connected to the charging interface corresponding to the output unit 2, it is not charged. When the temperature control unit 3 adjusts the temperature of the battery 9 to a temperature range suitable for charging, the controller 35 controls the electronically controlled switch 4 to close for charging. When the battery 9 is fully charged, the controller 35 controls the electronically controlled switch 4 to disconnect.

[0037] In some embodiments, the surface of the charging box 31 is also embedded with a display screen and an indicator light for displaying the charging status of the battery 9, as well as a touch screen, a control button, a main switch, etc., for the operator to control the system.

[0038] See also Figure 3 , Figure 3 It is a flow chart of a method for using a multi-mode power supply charging system provided by an embodiment of the present invention.

[0039] In a second aspect, the present invention further provides a method for using the multi-mode power supply charging system, using the multi-mode power supply charging system, comprising the following steps: S1 . Connect an external power source to a corresponding interface of the input unit 1 , and connect a battery 9 to the output unit 2 .

[0040] S2. The temperature control unit 3 adjusts the temperature of the battery 9 to between a low temperature threshold and a high temperature threshold.

[0041] S3. Charge the battery 9, and during the entire charging process, the temperature control unit 3 maintains the temperature of the battery 9 between a low temperature threshold and a high temperature threshold.

[0042] In some embodiments, step S2 specifically includes: The temperature measuring device 33 detects whether the temperature of the battery 9 is within a range suitable for charging, for example, the low temperature threshold is set to 25°C and the high temperature threshold is set to 35°C. If yes, the electric control switch 4 is closed to start charging; if no, when the temperature is lower than or equal to 25°C, the heating device 32 is started to heat the battery 9; when the temperature is higher than or equal to 35°C, the fan 34 is started to cool the battery 9 until the temperature of the battery 9 is within a suitable range, and then the electric control switch 4 is closed to start charging.

[0043] In some embodiments, step S3 specifically includes: S31. During the charging process, the temperature measuring device 33 keeps measuring the temperature of the battery 9, and controls the heating device 32 or the fan 34 to start or stop accordingly, so that the temperature of the battery 9 is kept between the low temperature threshold and the high temperature threshold. For example, when the temperature of the battery 9 is between the low temperature threshold and the high temperature threshold, the heating device 32 or the fan 34 does not work. When the temperature of the battery 9 is equal to or higher than the high temperature threshold, the fan 34 is started to cool down. When the temperature of the battery 9 is equal to or lower than the low temperature threshold, the heating device 32 is started to heat.

[0044] S32, check whether the power level of the battery 9 reaches the requirement, if not, keep the electronic switch 4 closed and continue charging; if yes, control the electronic switch 4 to be disconnected and stop charging.
