Description

Multi-functional portable power source module

Technical field

The utility model relates to field of power supplies, relates in particular to a kind of multi-functional portable power source module.

Background technology

Lithium ion battery is because the high-power height of capacity; The increasing various portable power sources field that is applied to; But present portable power source generally has only DC/DC (DC-DC) mapping function of power supply discharge, does not have the management of charging and discharging function and the charge and discharge protecting function of lithium ion battery; To above problem, application for a patent for invention number is that 200310102248 patent application provides a kind of a kind of intelligent portable power source of being made up of intelligent battery group connection of intelligent charger and output controller.

But the charging voltage of the intelligent portable power source that this patent application provides can only be used the alternating current of 100-240V, can not use vehicle power, has limited the scope of application of portable power source; The function that existing portable power source does not much all have dump energy to show; Even there is the precision of dump energy Presentation Function also very poor; Indication when the intelligent portable power source technology that provides like above-mentioned patent application only provides electric weight not enough: present stage high capacity lithium ion battery ubiquity consistency difference phenomenon; When adopting series model to use; Because the consistency of battery is poor, the phenomenon that the part battery can't be full of occurs, and along with the increase of using cycle-index; This problem can aggravate to occur gradually: the various portable sets that use now vary to the requirement of input voltage; Can't use single voltage output, above-mentioned patent application has had the portable power source of output 5-20V voltage range, still; This portable power source can't read the requirement of various portable electric appts self to the input voltage specification: present portable set is much all supported SMBUS2.O (System Management Bus 2.O) agreement or supports the agreement of other one-wire interface that portable power source is not all supported the agreement of SMBUS2.O or the agreement of other one-wire interface now; More than these drawbacks limit the scope of application of existing portable power source.

The utility model content

The purpose of the utility model is to provide a kind of wide multi-functional portable power source module of the scope of application that adopts the multi-string lithium ion battery series-fed.

The purpose of the utility model realizes through following technical scheme.

A kind of multi-functional portable power source module; Comprise: ASIC main system control module, input charge control module, output discharge administration module, communication protocol processing module, demonstration and key-press module, Balance Treatment module, outside jointing processing module, battery charge discharge administration module; The ASIC main system control module is electrically connected with input charge control module, output discharge administration module, communication protocol processing module, demonstration and key-press module, Balance Treatment module, outside jointing processing module, battery charge discharge administration module, and the battery charging and discharging administration module is electrically connected with the Balance Treatment module.

Preferably, outside jointing processing module comprises output cathode, output negative pole, port and the programmable element of power supply, and programmable element is connected with the ASIC main system control module through port.

Preferably, said programmable element is an eeprom memory.

The utility model embodiment compared with prior art, the multi-functional portable power source module of the utility model through the input charge control module can use vehicle power and AC power that system is charged simultaneously; Through using the battery charging and discharging administration module to carry out the charging and discharging management, make electric weight indication accuracy less than 1% through making power consumption bulk registration battery electric quantity: the portable set switching system data that can realize and support SMBUS2.O agreement or other single-wire-protocol through the communication protocol processing module to all size lithium ion battery; Can realize uneven lithium ion battery equilibrium charging through the Balance Treatment module: can use the individual palpation key to regulate the specification of output voltage through demonstration and key-press module, output discharge administration module, can show the dump energy of battery; Through outside jointing module can use outside jointing control output voltage enable whether require consistent with judge module output specification with interface equipment; Can realize power supply through using different joints to notebook computer, mobile PC, portable CD/VCD/DVD player, MP3, MP4, mobile phone, digital camera, palmtop PC, game machine and other portable electric appts; Function is many, and the scope of application is wide.

Embodiment

For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

See also shown in Figure 1; Multi-functional portable power source module comprises ASIC main system control module, input charge control module, output discharge administration module, communication protocol processing module, demonstration and key-press module, Balance Treatment module, outside jointing processing module, battery charge discharge administration module; The ASIC main system control module is electrically connected with input charge control module, output discharge administration module, communication protocol processing module, demonstration and key-press module, Balance Treatment module, outside jointing processing module, battery charge discharge administration module, and the battery charging and discharging administration module is electrically connected with the Balance Treatment module.Above-mentioned other module all is under the control of ASIC main system control module, to accomplish function corresponding.

As shown in Figure 2; Outside jointing processing module comprises output cathode, output negative pole, port and the programmable element of power supply; Programmable element is EEPROM (electricallyerasable ROM (EEROM)), the demand power specification parameter of its storage inside external portable equipment.Programmable element EEPROM is connected with the ASIC main system control module through port, and the ASIC main system control module reads the stored parameter of programmable element through port.And the power parameter that this parameter and internal system are set relatively.

The parameter determining of programmable element the input power specification parameter of the corresponding portable electric appts of this jointing; After outside jointing processing module is passed through output cathode, output negative pole and port and the ASIC main system control module is connected; The ASIC main system control module can at first read the parameter value of joint internal programmable element, and relatively whether this parameter value is consistent with the parameter value of the setting of inside, when having only the two parameter consistent; The ASIC main system control module just can start power converting circuit; The power supply of output portable equipment requirement specification, if parameter is inconsistent, the portable power source module can be refused power supply; And remind the user to set the output parameter mistake through sound, light or other similar type of alarm, in time regulate the output specification make it with joint in parameter matching.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
