Abstract
The utility model relates to a lithium battery protective plate for a starting power supply. The lithium battery protective plate comprises a lithium battery pack, and each individual battery in the lithium battery pack is connected in parallel with a constant voltage circuit that performs charging protection on the battery. The lithium battery protective plate for the starting power supply is advantaged by low cost and high reliability.
Description
Technical field
The utility model relates to a kind of power supply lithium battery protection board that starts.
Background technology
Lithium-ions battery, due to its specific energy is large, and specific power is high, and the life-span is long, the pollution-free good characteristic of Denging, has become the first-selection of current many industry use batteries.In order to ensure that battery has good service behaviour; more safe and reliable and extend actual life; nearly all battery pack has all been equipped with the protective circuit that battery operated situation is managed, to control the voltage discharging and recharging and to allow the electric current passing through, the injury that battery is not abused.
Start power acquisition lithium battery, all need a block protection plate to carry out charge and discharge protecting to battery, due to discharging current super large, more than instant starting currents reaches 200a, generally adopt main metal-oxide-semiconductor parallel way.Start power requirement and be discharge and recharge with mouthful, how to realize the charge protection to battery, especially the over-charge protective of battery is very crucial, adopts metal-oxide-semiconductor mode to protect, and has the shortcoming of the high and poor reliability of the cost of baffle.
Summary of the invention
The purpose of this utility model is to provide the startup power supply that a kind of cost is low, reliability is high lithium battery protection board.
For reaching goal of the invention the technical solution adopted in the utility model, be:
A kind of power supply lithium battery protection board that starts, comprises lithium battery group, it is characterized in that: on each cell of described lithium battery group all and be connected to a pair of its and carry out the constant voltage circuit of charge protection.
Further, described constant voltage circuit is to be composed in series by voltage stabilizing didoe and current-limiting resistance.
The utility model when charging by voltage stabilizing didoe by the voltage control of cell between 3.5-3.7V, guarantee that lithium battery group do not overcharge, do not need metal-oxide-semiconductor protection.Startup power supply of the present utility model can be supported the moment 5S electric discharge between 200-500a, and electric current can be selected, and discharge prevention adopts detection monomer battery voltage and over-current detection to control metal-oxide-semiconductor protection.
The beneficial effects of the utility model: cost is low, reliability is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is further described, but the utility model is not confined to these embodiments.One skilled in the art would recognize that the utility model contained all alternatives, improvement project and the equivalents that within the scope of claims, may comprise.
With reference to Fig. 1, a kind of power supply lithium battery protection board that starts, comprises lithium battery group 1, on each cell of described lithium battery group 1 all and be connected to a pair of its and carry out the constant voltage circuit 2 of charge protection.
Described constant voltage circuit 2 is to be composed in series by voltage stabilizing didoe and current-limiting resistance.
The utility model when charging by voltage stabilizing didoe by the voltage control of cell between 3.5-3.7V, guarantee that lithium battery group do not overcharge, do not need metal-oxide-semiconductor protection.Startup power supply of the present utility model can be supported the moment 5S electric discharge between 200-500a, and electric current can be selected, and discharge prevention adopts detection monomer battery voltage and over-current detection to control metal-oxide-semiconductor protection.
