Fig. 1-2 is referred to, this utility model provides a kind of technical scheme：A kind of Large Copacity high output voltage charger baby, bag
Plastic material shell is included, the inside of the plastic material shell is equiped with lithium-ion electric core, the inside of the plastic material shell
Damping rubber is also filled with, the lithium-ion electric core is arranged using 4 and 4 string connected modes, and the lithium-ion electric core is mono- using 14.8V
Section capacity 3400mAH design, the lithium-ion electric core are externally connected to Charge Management IC and Seiko protection circuit, described to fill
Fulgurite reason IC and Seiko protection circuits are designed for integration-in-one, and the middle part of the Charge Management IC and Seiko protection circuits is also
It is connected with accurate coulant meter chip.
Market does not have industrial circle special charging precious at present.This project is using 4 and 4 string Sanyo 3400mAH battery cores, total to hold
Amount 13.6AH Large Copacity designs, can meet the conventional industrial equipment electric power of one day and supplement requirement.
Prior art products are easily overheated when high-voltage large current charges, and this product adopts such as rhythm application-specific integrated circuit, by changing
Enter circuit design and rational PCB layout designs, make charge efficiency reach more than 95%, reduce heating loss.
Prior art battery adopts voltage detecting electricity mode low precision, this product to adopt special coulant meter, accurately can examine
Survey current residual electricity.
Existing charger baby can only meet 1 meter of height fall-down test, and this project adopts new type plastic material envelope, interior filling
Damping rubber, meets 2 meters of height fall-down tests and requires
1. battery protecting circuit part：
U3, Q2, Q3, U4 constitute battery protecting circuit and coulant meter, realize over-charging of battery, cross put, excessively stream and short-circuit protection
With electricity accurate measurement.Totally 4 LEDs can show current residual electricity for D2, D3, D5, D6.
2. battery charges and intelligent management part：
U1, Q1, L1 composition charging circuit part.Realize battery large current charge.
3. contour structures part：
Using new type plastic material envelope, interior filling damping rubber, meet 2 meters of height fall-down tests and require.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
Be appreciated that these embodiments can be carried out various changes in the case of without departing from principle of the present utility model and spirit, repair
Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
