Abstract
The utility model discloses a novel mobile power supply with a micro management system. The novel mobile power supply is characterized in that a control unit is arranged in the mobile power supply; the control unit can control a bidirectional DC/DC converter, and produces PWM pulse width which controls the bidirectional DC/DC converter; and the control unit can detect the temperature, the voltage and the current of a battery to control an equalization circuit of three batteries. In the management system, the passive equalization circuit is provided for the batteries. A battery with too high terminal voltage is discharged, until balance matching of the terminal voltage of three batteries is realized. Any port in bidirectional direct current ports can be used as a charging port, and can be used as a discharging port. The novel mobile power supply provided by the utility model has the advantages that the mobile power supply can directly access city power for charging, which frees the mobile power supply from the dependence on a power supply adapter; the era of the mobile power supply without a management system is ended; the use state of the batteries of the mobile power supply is ensured from the source; and the service life of the mobile power supply is effectively prolonged.
Description
Technical field
The utility model relates to field of power supplies, is specifically related to a kind of novel portable power source with microtubule reason system.
Background technology
Along with the fast development of global economy, improving constantly of people's living standard, portable electronic product is also more and more, as notebook computer, panel computer, mobile phone, digital camera, video camera, portable DVD player, PDA, MP3, MP4, GPS, warming equipment, medical health equipment etc.They all will use battery, but first wife's battery of these equipment all can not meet because battery capacity is low the long-time use of equipment.In the time going on business or travel, be again the work peak period of these equipment, through be everlasting crucial moment battery do not had electricity, particularly in the time that mobile phone is made a phone call, when digital camera is being taken pictures, PSP game machine play just hard time, when PDA is working etc., allow you feel to have no alternative and helpless.And you also can not join a reserve battery every kind of equipment, not only cost is high nor convenient.Based on this, in order to solve people's this worried problem, portable power source arises at the historic moment.
The appearance of portable power source, has alleviated intelligent terminal and has made the problem of power consumption deficiency undoubtedly in present stage, portable power source portable, movably feature brings great convenience to us.Portable power source has now belonged to free articles under passenger, is ensureing, on the basis of product capacity, how to reduce the volume of product, allow more miniaturization of product, portable be one of the trend of portable power source outward appearance technological innovation.Secondly, how advanced Industrial Design Idea or even Humanistic Concepts are used in the appearance design of portable power source, allow portable power source feel more comfortable, have more fashion breath, be also the trend of portable power source technological innovation.
At present, the portable power source of the marketization is mostly with bidirectional, dc port, an i.e. DC charging mouth (mini USB mouth) and a direct-current discharge mouth (USB mouth), thereby need to be equipped with a DC charger to portable power source and could charge, not Portable belt; In addition, prior art is used the portable power source of several cell parallels to only have the GPF (General Protection Falses such as temperature, overcurrent, overvoltage to some inside, and poor without balanced measure, battery consistency in charging and discharging use procedure.
Summary of the invention
In order to address the deficiencies of the prior art, the utility model provides a kind of novel portable power source with microtubule reason system, portable power source can directly be accessed commercial power charged, portable power source to freeing the dependence of power supply adaptor.Finish the epoch of portable power source without management system, ensure the use state of portable power source battery from source, effectively extend the life-span of portable power source.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of novel portable power source with microtubule reason system, is characterized in that: be describedly provided with control unit in portable power source inside; Described control unit can be controlled two-way DC/DC converter, produces and control the PWM pulsewidth of two-way DC/DC converter; Described control unit can also detect temperature, the voltage and current of battery, to control the equalizing circuit of three batteries.
The interface that outreaches of described portable power source comprises plug and bidirectional, dc port; Described bidirectional, dc port comprises USB mouth and mini USB mouth.
The connected mode of described two kinds of bidirectional, dc ports is for being connected in parallel.
In described management system for battery is equipped with passive equalizing circuit, by battery discharge too high terminal voltage, until three batteries terminal voltage balanced Matchings.
Each port in described bidirectional, dc port both can be used as charge port, can be used as again discharge port.
The beneficial effects of the utility model are: the utility model provides a kind of novel portable power source with microtubule reason system, portable power source can directly be accessed commercial power charged, portable power source to freeing the dependence of power supply adaptor.Finish the epoch of portable power source without management system, ensure the use state of portable power source battery from source, effectively extend the life-span of portable power source.
