Specific embodiment
The present invention is described in detail with implementation method below in conjunction with the accompanying drawings.
Fig. 1 is referred to, Fig. 1 is the schematic flow sheet of the implementation method of activation method for lithium battery of the present invention.It is noted that
If there is substantially the same result, the method for the present invention is not limited with the flow order shown in Fig. 1.As shown in figure 1, the method
Comprise the following steps：
S101：Detect the voltage of lithium battery.
Lithium battery (Lithium Battery) refer in electrochemical system containing lithium (including lithium metal, lithium alloy and lithium from
Son, lighium polymer) battery.Lithium battery is broadly divided into two classes：Lithium metal battery and lithium ion battery.Lithium metal battery is included
The lithium of metallic state, it is typically non-rechargeabel.Lithium ion battery does not contain the lithium of metallic state, and can charge.Therefore it is of the invention
Described lithium battery refers to lithium ion battery.
If lithium battery lays up for a long time, lithium battery meeting automatic discharging, placing more long voltage can be lower.Work as lithium battery
When battery core voltage is less than certain voltage threshold, such as during 2.4V, the portion of material in lithium battery can start to be destroyed.Therefore, lithium
During battery discharge, foregoing voltage threshold had better not be put into and just stopped.In addition, for a kind of lithium battery, due to lithium battery from
During voltage higher such as 3.0V discharges into 2.4V this section, the energy for being discharged only accounts for 3% of battery capacity or so.Therefore,
3.0V is a preferable discharge cut-off voltage for this lithium battery.Here, 3.0V is defined as this lithium battery
Protection voltage.Therefore before to lithium cell charging, the voltage of lithium battery is first detected.If the voltage of lithium battery is more than lithium battery
Protection voltage, then directly to lithium cell charging.If the voltage of lithium battery then needs first to swash less than or equal to protection voltage
Lithium battery living, then can just be charged.
Wherein, the voltage of detection lithium battery can be detected using singlechip chip.
S102：Whether the lithium battery voltage according to detection judges lithium battery in guard mode.
Wherein, the lithium battery voltage for detecting is compared with the protection voltage of lithium battery, and judges that lithium battery voltage is
It is no less than protection voltage.If the lithium battery voltage for detecting is in guard mode less than protection voltage, control lithium battery.It is this
Guard mode is the state do not discharged and can not charge.
Wherein, the detection voltage and protection voltage for comparing lithium battery can be compared using singlechip chip.
S103：If lithium battery is in guard mode, amplify the lithium battery electricity that charger moment receives when accessing

Pond to fill overvoltage higher, it is dangerous also higher.When lithium battery is crossed is charged to voltage higher than certain voltage threshold such as 4.2V, meeting
Start to produce side effect.This lithium cell voltage higher than after 4.2V, in positive electrode remaining lithium atom quantity less than half, this
When memory location can often collapse, allow battery capacity to produce permanent decline.If continue charge, due to negative pole memory location
Lithium atom is loaded with, follow-up lithium metal can be piled up in negative material surface.These lithium atoms can be from negative terminal surface toward lithium ion
The direction come grows ingotism, and the crystallization of these lithium metals can make both positive and negative polarity short circuit through diaphragm paper.Sometimes occur in short circuit
Preceding battery just first explodes, because in the process that overcharges, the material such as electrolyte can crack generation gas so that battery case or pressure
Power valve blow-up ruptures, and allows oxygen to enter to be reacted with the lithium atom for being deposited in negative terminal surface, and then explode.Therefore, lithium cell charging
When the voltage of lithium battery must be detected.When the voltage for detecting lithium battery reaches upper voltage limit, necessarily stop in time
Only lithium battery is charged.For the lithium battery of aforesaid kind, the optimal charging voltage upper limit is 4.2V.

Pressure signal.
Can as above described in S103, therefore not to repeat here.
S204：The voltage of charging transient is gathered, first voltage is defined as, and be converted into pulse signal.
S205：Amplify pulse signal, produce the high level pulse signal for amplifying, then drive lithium cell charging control circuit
Conducting, lithium battery is entered charged state.
Wherein, the voltage for being gathered must be converted into pulse signal, then be amplified.Reason is high level pulse letter
