Description
Technical field
The present invention relates to a kind of battery module, electronic installation and battery hot-swap method, and be particularly related to a kind of battery module, electronic installation and the battery hot-swap method that can hot substitute.
Background technology
Along with development of science and technology, the application of portable electronic devices is more and more general.For the portable characteristic in response to portable electronic devices, the use of battery is considerably important.Yet the capacity of battery is often limited, and therefore, how can change battery expediently whether expediently become user's one of key of operating electronic devices.
In the tradition, the electric power running that electronic installation utilizes main battery to provide.The built-in one group of reserve battery of electronic installation is with the replacing of auxiliary main battery.Reserve battery temporarily provides electric power to give electronic installation, to allow electronic installation can carry out the replacement of main battery under hibernation (hibernate) pattern or dormancy (sleep) pattern.Reserve battery can be divided into rechargeable type maybe can not fill formula.Can not fill the formula reserve battery and be generally lithium metal battery, and the rechargeable type reserve battery is generally Ni-MH battery, lithium ion or lithium macromolecule battery.
Can not fill the formula reserve battery is lithium metal battery, because lithium metal battery can't utilize the mode of charging to recover electric weight, therefore, the user needs to substitute before the electric weight of lithium metal battery is exhausted.Otherwise, if the voltage of lithium metal battery is constantly toward descending, may be on fire and explode.In order to reduce above-mentioned situation, need to set up caution mechanism in the electronic installation, soon exhausted with the instant electric weight of notifying user's reserve battery.In addition, electronic installation also need have the mechanism of being convenient to substitute reserve battery.Thus, the reserve battery of this kind form is not only dangerous high, and easily causes user's inconvenience.
With the rechargeable type reserve battery is Ni-MH battery, because general main battery is a lithium ion battery, therefore, the charging mechanism of main battery and reserve battery is different.In more detail, the charging circuit corresponding to main battery and reserve battery in the system needs other design, and need set up selector in the system, simultaneously main battery and reserve battery are charged.Thus, the complexity of the design of charging circuit increases, and increases the cost expenditure.
In addition, with the rechargeable type reserve battery is lithium ion or lithium macromolecule battery, though main battery be all the battery of lithium form and have identical charging mechanism with reserve battery, yet, the capacity of main battery and reserve battery is different, makes the electric current to main battery and reserve battery charging also need different.Thus, the charging circuit of electronic installation inside still needs special design.In addition; lithium ion or lithium macromolecule battery are because of having high activity, and therefore, electronic installation is inner need to design perfect protective circuit plate (protectioncircuit module; PCM) and detect the mechanism of the electric power of main battery and reserve battery, whole manufacturing cost is increased.
In addition, the reserve battery of above-mentioned which kind of form of electronic installation configuration no matter all need be reserved the space of ccontaining reserve battery in the electronic installation, make the flexibility decrease of the spatial configuration of electronic installation.In addition, utilize reserve battery to assist the mode of the replacing of main battery often need allow electronic installation enter park mode or hibernate mode earlier, just electronic installation can't operate constantly under normal mode (normal operation), therefore, the user must be interrupted the work carried out on electronic installation.For the user, this kind substitutes the mode inconvenience in the extreme of battery.
Therefore, how to design a kind of heat of utilizing and substitute, just electronic installation is kept running under normal mode, substitutes the battery of electronic installation, is one of problem of making great efforts for relevant dealer.

Embodiment
First embodiment
Please refer to Fig. 1, it is depicted as the schematic diagram according to the electronic installation of first embodiment of the invention.The equipment that the electronic installation 110 of present embodiment can hot be substituted for battery comprises first battery 300, processor 113, battery connector 111c, the first supply hub 111h and battery module 120.Battery module 120 comprises second battery 121 and power line 122.
When the electric weight of first battery 300 is about to when exhausted, the user can utilize second battery 121 and power line 122 should be used for keeping to operate at electronic installation 110 carry out heat under the normal mode and substitute (hotswap).That is to say that electronic installation 110 need not to enter the pattern of low power consumption, for example is park mode or hibernate mode, can carry out the replacing of battery.Below will further specify.
When the user connects the first supply hub 111h and second source jack 121h with power line 122, second battery 121 provides power supply to give electronic installation 110 by power line 122, and processor 113 is according to the identification signal of identification pin position, and forbidden energy charges to first battery 300 to meet among the IEEE standard about battery by battery connector 111c.
Please refer to Fig. 2 and Fig. 3, Figure 2 shows that electronic installation carries out the schematic diagram that heat is substituted, and Figure 3 shows that electronic installation finishes the schematic diagram that heat is substituted.As shown in Figure 2, when being connected in battery connector 111c when second battery, 121 replacement first batteries 300, second battery 121 provides power supply to give electronic installation 110 by battery connector 111c, and stops to provide power supply to give electronic installation 110 by power line 122.Thus, as shown in Figure 3, the user can further remove power line 122.
Whole sight, when carrying out the battery replacement, because second battery 121 provides electrical power to electronic installation 110 by power line 122 constantly, therefore, electronic installation 110 is kept and is operated under the normal mode.The situation that need be introduced into park mode or hibernate mode with electronic installation when substituting battery is compared, and the electronic installation 110 of present embodiment can be finished heat under the normal mode and substitute operating on, therefore, the operation of electronic installation 110 and use comparatively convenient.
In present embodiment, first battery 300 and second battery 121 for example are identic battery, and the connecting interface that respectively has two kinds of forms, to couple with power line 122 and battery connector 111c respectively.
In addition, please refer to Fig. 4 A, it is depicted as an example of first supply hub, second source jack and power line.The first supply hub 111h and second source jack 121h, and the form of an end p1 of power line 122 and other end p2 for example is shown in Fig. 4 A.The first supply hub 111h and second source jack 121h respectively have an identification pin position pi, and an end p1 of power line 122 and other end p2 have the hole of ccontaining identification pin position pi, to cooperate with first supply hub 111h with identification pin position pi and second source jack 121h.
