Abstract
The utility model relates to a composite storage battery, which is composed of a storage battery, a super-capacity capacitor and a current limiter, wherein, the storage battery is connected with the super-capacity capacitor; the current limiter is connected between the storage battery and the super-capacity capacitor. The utility model has the advantages that the utility model can realize short-time high-magnification discharge, consequently extending the life time of an acid storage battery, and improving the discharge characteristic of the alkaline storage battery, and thus the utility model can be suitable for the high requirements of the power supplies of motor vehicles such as an automobile, a motor vehicle, etc.
Description
The utility model relates to a kind of compound storage battery.
Though existing acid cell discharge-rate height, the life-span is short, though and the alkaline battery life-span is long, energy storage is high, discharge-rate is little.
The purpose of this utility model provides a kind of compound storage battery that can prolong the life of storage battery, improve the flash-over characteristic of storage battery.
The purpose of this utility model is achieved in that it is made up of storage battery, capacitor with super capacity, flow restricter, and storage battery is in parallel with capacitor with super capacity, and flow restricter is connected between storage battery and the capacitor with super capacity.
Capacitor with super capacity is made of by stack and corresponding connection in series-parallel plural basic capacitor cell, each basic capacitor cell is made up of current-collector, electrode, barrier film, electrode, current-collector five-layer structure, electrode is made of porous material, all be soaked with electrolyte in barrier film and the electrode, each electrode, barrier film, current-collector periphery are provided with insulator, and whole capacitor is encapsulated in the housing.
Flow restricter is resistance or intelligent current-limiting circuit.
Storage battery is acid cell or alkaline battery.
The utility model has the advantages that this compound storage battery can realize in short-term the high-multiplying power discharge of (in 10 seconds), thereby prolong the life-span of acid cell, improve the discharge characteristic of alkaline battery, to adapt to the high requirement of motor vehicles such as automobile, motorcycle to power supply.
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, the utility model is made up of storage battery 2, capacitor with super capacity, flow restricter 1, and storage battery 2 is in parallel with capacitor with super capacity, and flow restricter 1 is connected between storage battery and the capacitor with super capacity.
Capacitor with super capacity is made of by stack and corresponding connection in series-parallel plural basic capacitor cell, each basic capacitor cell is made up of current-collector 9, electrode 7, barrier film 8, electrode 7, current-collector 9 five-layer structures, electrode is made of porous material, all be soaked with electrolyte in barrier film and the electrode, each electrode, barrier film, current-collector periphery are provided with insulator 10, and whole capacitor is encapsulated in the housing 11.
Flow restricter adopts resistance or intelligent current-limiting circuit.
Storage battery is acid cell or alkaline battery.
Operation principle of the present utility model is as follows:
When the compound use of capacitor with super capacity (general Capacity Ratio is determined as required) of storage battery and suitable capacitance and operating voltage, charge to capacitor with super capacity by flow restricter by storage battery at ordinary times, when electrical appliance needs in short-term big electric current (start, quicken) as motor vehicle, provide electric current more than 2/3rds by capacitor with super capacity, the storage battery part then can reduce big halfload.
