When guarantee equipment and user safety.When equipment is when being discharged, periodical acquisition can be carried out to induced current, when electric current is big
When about 3A, equipment will do it protectiveness power-off, and high current is avoided to cause caused security risk of generating heat.And relay is using double
Knife structure thoroughly allows the output of socket and AC220V to be thoroughly detached from, including zero curve and firewire.
User opens Bluetooth of mobile phone and starts APP, selects equipment connection, and last user's real consumption note is obtained after successful connection
Record (if any network, uploads, such as without network, upload after being stored in local waiting networking) immediately, if user local remaining sum is not
0, then charge request is initiated to equipment according to the consumption habit of user's default setting (such as: charging four hours), equipment starts to supply
Electricity, countdown are opened.It is zero that electric current is detected in midway, and automatic terminate is powered, and uploads preservation real consumption immediately and local is recorded, or
Person etc. is to be uploaded.If user local remaining sum is 0, balance amount prompting is insufficient, please network and supply remaining sum or supplement with money.
User's connection, equipment power supply, actively or after passive stopping charging equipment is automatically stopped power supply.
This system is based on Bluetooth of mobile phone and power supply unit interaction, and user first opens APP and chooses socket, automatic by bluetooth
The socket in connection, APP can carry out authorization unlatching to equipment according to the local remaining sum of this user, and according to charging set by user
Time, opening timing power supply logics, the time to be automatically stopped power supply.
This system follows in principle fills time computation rule in fact, and user's charging expense is allowed to be preferably minimized as far as possible.If filled
Occur accident during electricity, actively or passively abandon charging, charging socket can be automatically stopped power supply, and when calculating practical charging
Between, it is ensured that equipment safety and user's right is avoided to cause damages, user applies for the difference portion in charging time and practical charging time
Point, it can be delayed and retract user account.The situation of charging termination has following several:
Fair termination, charging equipment fill with, and for charging current close to the static working current of charger, system can be automatic
Stop electric discharge.
Active termination, charging be user filled a period of time actively pull out charger after, system can detect electric current be 0,
Stop electric discharge.
Passive to terminate, to pull out plug by other people during charging, system can detect that electric current is 0, and stop the feelings of electric discharge
Condition.
Abnormal end surpasses since charger itself is abnormal or user has used other electrical appliances and causes electric current excessive
The upper limit value of this system is crossed, system will do it self-shield and carry out stopping electric discharge.The process of above-mentioned charging is using existing base
This information collection, the program of signal contrast and signaling switch, the program or method being related to are to belong to existing method.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, can also make several improvements and retouch, these improve and
Retouching also should be regarded as the protection scope of the utility model.
