Description
Technical field
The utility model is related to the technical field of Electric Manufacture more particularly to a kind of multifunctional portable charging devices.
Background technology
It generally needs to use storage battery on cannon, it not only can be as the mains lighting supply of cannon, but also was the percussion power supply of cannon
And startup power supply.In order to make cannon under the conditions of bird-walking weather or when night instructs, smoothly complete prolonged shooting combat mission or
Person's daily teaching training mission, when lighting tool, electric shoot device, electronic feed machanism persistently consume electric energy, in addition to holding to storage battery
Amount has to voltage stability, a wide range of adjustability of voltage and current, AC-DC conversion flexibility etc. outside there are certain requirements
It asks.
Important component of the storage battery as the full big gun power supply system of cannon connects salvo, artillery concentration, control entirely in guarantee cannon
Cannon processed is beaten together to stop etc. to play a crucial role together, simultaneously because charging battery jar can be made with continuous several times charge and discharge
With maintaining is convenient and efficient, is the only option of cannon power configuration.However at present with big gun be equipped with storage battery there are performances not
Stablize, charge maintenance is difficult, the defects of having a single function, seriously affects storage battery service life, part operation when leading to artillery shooting
It can not continue to carry out, Military Equipment Battling efficiency can not play, specific as follows：
