Description
Technical field
The utility model belongs to battery protection system field, is specifically related to a kind of system preventing over-charging of battery and excessively put.
Background technology
Current portable electric appts, such as mobile phone, digital camera, panel computer, extensively distribute.Therefore, each large manufacturer is developing for providing electric power energetically to operate the battery of the improvement of portable electric appts.
Battery is provided with the battery pack of protective circuit, and this protective circuit is for controlling the charge/discharge of battery.In battery pack, during charge or discharge process, defect can occur in battery or protective circuit, and therefore protective circuit comprises the various instrument of the charging and discharging for stably controlling battery.
Battery discharges the electricity of internal reservoir, and after voltage reaches certain value, continuing electric discharge will cause overdischarge, usually determines discharge cut-off voltage according to discharging current.Battery is crossed to put to cross to the consequence of bringing on a disaster property of battery, particularly big current and is put, or battery impact of being repeatedly excessively rivals in a contest is larger.Generally speaking, overdischarge can make inner pressure of battery raise, and both positive and negative polarity active material invertibity is damaged, even if charging also can only partly recover, capacity also has obvious decay, and the useful life of battery is shortened.
Utility model content
One of the purpose of this utility model is to provide a kind of system preventing over-charging of battery and excessively put.
The utility model provides a kind of and prevents over-charging of battery and cross the system of putting, and comprising: control module, voltage detection module, current detection module, switch element, load protection unit and battery pack;
Described control module connects described voltage detection module, current detection module and switch element;
Described battery anode connects described current detection module, and described battery electrode connects described load protection unit;
Described control module connects described load protection unit by described switch element;
Described voltage detection module connects described current detection module.
Further, described switch element is also provided with an earth terminal.
Further, described control module adopts chip model to be S8261 or R5405.
The beneficial effects of the utility model are; what the utility model provided a kind ofly prevents over-charging of battery and crosses the system of putting in battery charging process; if overcharge protection circuit lost efficacy and battery when occurring overcharging, switch element can act on the charging circuit cutting off battery in time, prevented over-charging of battery.Automatic equalization can be carried out to the battery unit of low voltage, adopt hardware to control in real time.Effectively can suppress the super-charge super-discharge phenomenon of battery unit in series battery, make battery pack within the shortest time, improve the consistency of battery pack, thus extend the useful life of battery pack, there is control convenience, respond rapid, failure rate is low, feature with low cost.
