Abstract
The utility model discloses a high-efficiency lithium battery charging power supply. The power supply comprises a power supply end, a charging part, a rectifying module and a power supply manager. The power supply end and the charging part are connected through the rectifying module. The charging part is provided with at least one charging groove. A lithium battery is placed in the charging groove for a charging purpose. When the lithium battery is fully charged, the power supply manager connected with the charging part breaks the circuit of the charging groove. A protection circuit is arranged between the power supply end and the charging part. The power supply which has a simple structure and adds the protection circuit can automatically stop charging after the lithium battery is fully charged and thus prolong the service lifetime of the lithium battery. By arranging the rectifying module, the power supply increases the current output during a charging process and thus shortens the charging period.
Description
Technical field
The utility model relates to a kind of lithium cell charging power supply, particularly a kind of high efficiency lithium cell charging power supply.
Background technology
Now, lithium battery is because lightweight, the good low price of conductivity and little with impact to the harm of environment, obtained good development, occupy center of gravity at battery industry, under charged state, if the charging voltage of lithium battery repeats to surpass the state more than 4.3 volts, have smolder, the danger of on fire even blast.Be lower than such as the voltage of lithium battery under 2.0 volts the state and place for a long time, then lithium battery can't re-use or charge.People can not keep on the battery next door always, after battery is saturated, can not automatically stop, overcharge or when discharging (use), accident even blast that life-span that can the contracting lithium battery or occur can not expect need the stand-by period for a long time in charging process, sometimes people are badly in need of using, under the prerequisite of not damaging battery, shorten the charging interval, be present defective, therefore, need to improve.
Implementation content
[0003]The technical problems to be solved in the utility model is for overcoming weak point of the prior art; a kind of simple structure be provided, increase circuit protection, lithium battery saturatedly stops charging automatically afterwards, prolong lithium battery useful life; rectification is set; strengthen the electric current output of charging process, shorten the high efficiency lithium cell charging power supply in charging interval.
For solving technical problem of the present utility model, the technical scheme that adopts is: a kind of high efficiency lithium cell charging power supply, comprise a power source supply end, charging part, rectification module, power supervisor, be connected by described rectification module between described power source supply end and the described charging part, described rectification module is used for increasing electric current output, quick charge, described charging part is provided with at least one charging slot, lithium battery is positioned in the described charging slot and charges, after lithium battery is saturated, the power supervisor that is connected with charging part disconnects the circuit of this charging slot, avoid overcharging, when power supervisor detects the lithium battery circuit when opposite with charging circuit, described power supervisor is changed charging circuit for lithium battery automatically, continues as lithium cell charging; Between described power source supply end and described charging part, protective circuit is set, guarantees the circuit safety of charge power supply;
Described charging part arranges battery indicator, and described battery indicator shows the electric quantity of lithium battery in this charging part;
