本発明はニッケルカドミウム蓄電池の充電器に関するも
のである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a charger for a nickel-cadmium storage battery.

脈流で電池（３１を充電する場合とがあった。Conventionally, when converting an AC power supply to DC and charging a nickel-cadmium storage battery (hereinafter referred to as a battery), the AC of the AC power supply part fl+ consisting of a step-down transformer T is rectified by a half-wave rectifier (2), as shown in Figure 1. The battery (31) can be charged with the pulsating current obtained by the pulsating current, or the battery 31 can be charged with the pulsating current shown in FIG. There were times when I did.

晶が上述のように粗大化して電解液と陰極との接触面積
が小さくなって容積の低下、或いは電圧の低下、充放電
寿命サイクルの低下を起こすという問題があった。However, since these chargers charge using direct current,
There was a risk that cadmium hydroxide crystals would form on the cathode during charging, causing the crystals to become coarse. There is no problem in practical use when charging and discharging are repeated in normal short cycles, but if you charge for a long period of time and then discharge occasionally,
For example, when emergency lights are discharged only during emergencies or inspections and are normally charged, the cadmium hydroxide crystals become coarse as described above and the contact area between the electrolyte and the cathode becomes smaller. There have been problems in that the volume decreases, the voltage decreases, and the charge/discharge life cycle decreases.
本発明は上述の問題点に鑑みて為されたもので、その目

供するにある。The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a charger that activates the inside of the battery during charging to prevent deterioration of battery characteristics and prolong the life of the battery. There is something to do.

is a main rectifier that half-wave rectifies the secondary output of the AC power supply section 11) consisting of a step-down transformer T, and a battery (3) is connected to the step-down transformer 310 secondary output via this main rectifier (2&). (2b) is a sub-rectifier, and this sub-rectifier (2b)
may be connected in series with a resistor (4) and connected from the main rectifier (input J'!1-) through the resistor (4).

電池（３）の特性を維持できることになるのである。Therefore, the forward current I of the main rectifier (2a) is the resistance (
Since there is no current limiting confectionery like 41, the current flows as a large pulsating current as shown in figure WJ6 and charges the battery (81).The reverse component current I2 is limited by the resistor (4) and flows through the sub-rectifier. (2b), and the battery (ill) is slightly forcedly discharged. This forced discharge reduces the crystallization of hF'3, hydroxide generated at the cathode during charging.
This means that the characteristics of the battery (3) can be maintained.

るという効果を奏する。As described above, the present invention connects a nickel cadmium storage battery to an AC power source via a main rectifier, connects a series circuit of a sub-rectifier and a resistor in parallel with the main rectifier, and connects the sub-rectifier in a reverse direction with respect to the main rectifier. Since the nickel-cadmium storage battery is connected in the directional direction, the nickel-cadmium storage battery can be charged by the main rectifier, and the nickel-cadmium storage battery can be forcibly discharged slightly by the sub-rectifier and the resistor, so the inside of the nickel-cadmium storage battery can be activated, and therefore the nickel-cadmium storage battery can be charged for a long time. Hydroxide on the cathode caused by periodic charging! This has the effect of preventing the crystals from becoming coarse (＋), preventing deterioration of characteristics, and increasing the life of the boat.
