Abstract
The utility model relates to an in-built charger electric bicycle lithium battery pack with an equalizing charge port. The in-built charger electric bicycle lithium battery pack with the equalizing charge port is composed by an alternating current power supply port, a charger module, an equalizing charge port module, a charge control module, a direct-current output module, an outlay equalizing charge module, a battery pack module and a charge-discharge negative electrode control module. The alternating current power supply port is connected with the charge module, the equalizing charge port module can be connected with the outlay equalizing charge module, and the battery pack module and the equalizing charge port module are respectively connected with the charge-discharge negative electrode. The charger module is designed as an integrated configuration of the electric bicycle and is combined and integrated with a battery pack combination, so that an electric bicycle can be charged with mains supply. A problem of unbalanced voltage in a single battery of a battery pack can be solved reliably, and an unbalanced battery can receive reparably equalizing charge. The in-built charger electric bicycle lithium battery pack with the equalizing charge port has the advantages of being compact in structure, effective in control, convenient to install, safe in use and the like.
Description
Technical field
The utility model relates to the automobile-used lithium ion battery bag of a kind of electrical salf-walking with the charger structure, specifically a kind of built-in charger formula lithium cell for electric bicycle bag with the equalizing charge interface.
Background technology
At present power brick and the charger of electric bicycle are separately independently, and the charger that does not match can not at will be used for the charging of electric bicycle, thereby to carry charger in the driving process be a very inconvenient thing.Simultaneously, occur monomer battery voltage in the battery of electric bicycle group when unbalanced, can only separate cell, can not the equalizing charge of reparation property.
Summary of the invention
The objective of the invention is to provide a kind of built-in charger formula lithium cell for electric bicycle bag with the equalizing charge interface, it can be set as charger the essential configuration of car load of electric bicycle effectively, and with the power brick combination accessory with form one; Solved reliably the unbalanced problem of monomer battery voltage in the battery pack, can be to the equalizing charge of unbalanced battery reparation property.
The technical scheme that the utility model is dealt with problems is: design a kind of by AC power interface, charger module, equalizing charge interface module, battery protection module, direct current output module, external equalizing charge module, battery module with discharge and recharge the built-in charger formula lithium cell for electric bicycle bag with the equalizing charge interface that the negative pole control module forms; AC power interface connecting charger module; the equalizing charge interface module can connect external equalizing charge module, discharges and recharges the negative pole control module and connects respectively battery module and equalizing charge interface module.
The beneficial effects of the utility model are: the beneficial effects of the utility model are: because AC power interface connecting charger module, thereby can directly connect AC power and charge to electric bicycle, and not need to wear in addition charger.Can connect external equalizing charge module owing to the equalizing charge interface module simultaneously, thereby can implement equalizing charge and utilize prosthetic appliance to carry out equalizing charge electric bicycle.The utility model also has advantages of compact conformation, control is effective, configuration is convenient and use safety.
Description of drawings
Fig. 1 is circuit block diagram of the present utility model.
Among the figure, 1, AC power interface, 2, charger module, 3, the equalizing charge interface module, 4, battery protection module, 5, the direct current output module, 6, external equalizing charge module, 7, battery module, 8, discharge and recharge the negative pole control module.
Embodiment
The embodiment that provides below in conjunction with Fig. 1 divides three parts that the utility model is further specified.
The first, discharge process.
During discharge, with electric bicycle in direct current output module (5) connection, the discharge of battery of electric bicycle bag.At this moment, battery protection module (4) detects voltage and the temperature of each cell in real time, when wherein a certain cell reaches the protection potential of overdischarge, discharges and recharges negative pole control module (8) action, and discharge finishes.
The second, charging process.
During charging, civil power in AC power interface (1) connection, charger module (2) is worked, and power brick is charged.At this moment, battery protection module (4) detects voltage and the temperature of each cell in real time, when wherein a certain cell reaches the protection potential that overcharges, discharges and recharges negative pole control module (8) action, and charging finishes.
The 3rd, equalizing charge.
During equalizing charge; external equalizing charge module (6) is connected equalizing charge interface module (3); because battery protection module (4) connects respectively battery module (7) and discharges and recharges negative pole control module (8); thereby; battery protection module (4) can be controlled charging process; when the voltage difference of each cell in the power brick≤5mV, discharge and recharge negative pole control module (8) action, equalizing charge is finished.
Claims (1)
1. built-in charger formula lithium cell for electric bicycle bag with the equalizing charge interface; it is characterized in that: it is by AC power interface (1); charger module (2); equalizing charge interface module (3); battery protection module (4); direct current output module (5); external equalizing charge module (6); battery module (7) and discharge and recharge negative pole control module (8) and form; AC power interface (1) connecting charger module (2); equalizing charge interface module (3) can connect external equalizing charge module (6), discharges and recharges negative pole control module (8) and connects respectively battery module (7) and equalizing charge interface module (3).
