電性能を悪化させている。Conventionally, in this type of charging device, a switching element (3) such as a transistor or a relay is inserted in series with a charging circuit for a solar cell (1) and a battery (2), as shown in FIG.
Charging is controlled by controlling this with an output signal from a voltage detection unit (4) that detects the voltage of the battery (2). (i) is a backflow prevention diode. Therefore,
When a transistor is used as the switching element (3), the effect of collector-emitter saturation voltage is
Furthermore, when a relay is used, it is easily affected by the contact resistance of the contacts, and in either case, the voltage of the solar cell (1) is reduced and the charging performance is deteriorated.

図、第２図および第４図に基づいて説明する。Therefore, the present invention connects a solar cell and a battery to be charged via a backflow prevention diode, connects a switching element in parallel with the solar battery, and controls this switching element according to the voltage of the battery to be charged. Hereinafter, one embodiment of the present invention will be described as the first embodiment.
The explanation will be given based on FIGS. 2 and 4.
第１図において、スイッチング素子（３）は太陽電池（
１）と並列に接続されて、電圧検出部（４）の出力で、

ッチング素子（３）をオフさせ、電池（２）の電圧が充
電設定電圧よりも高い場合にはスイッチング素子（３）
をオンさせるように制御されている。In FIG. 1, the switching element (3) is a solar cell (
1) is connected in parallel with the output of the voltage detection section (4),
If the voltage of the battery (2) is lower than the charge setting voltage J, the switching element (3) is turned off, and if the voltage of the battery (2) is higher than the charge setting voltage, the switching element (3) is turned off.
is controlled to turn on.
この場合、スイッチング素子（３）がオフの場合には、
太陽電池（１）の出力は逆流防止ダイオード（５）を介
して電池（２）を充電し、スイッチング素子（３）がオ
ンの場合には太１ｉＩＩＩＥ池（１）の出力は短絡され
て電池（２）の充電は停止する。In this case, when the switching element (3) is off,
The output of the solar cell (1) charges the battery (2) via the reverse current prevention diode (5), and when the switching element (3) is on, the output of the solar cell (1) is short-circuited and the battery (2) is charged. 2) Charging stops.
太陽電池（１）の特性は第４図に示すように定電流領域
と定電圧領域を有しており、太１Ｉｉｆ！を池（１）の

れている。The characteristics of the solar cell (1) have a constant current region and a constant voltage region as shown in FIG. Even if the output of the battery (1) is short-circuited, the current will be maintained constant due to its constant current characteristics, so it will not only have no negative effect on the large S battery (1), but will also reduce the consumption of the switching element (3). The electric power is also the product of the output current and the voltage drop of the switching element (3), and is very small compared to the output of the solar cell (1). When the switching element (3) is on, the backflow prevention diode (5) prevents the battery (2) from discharging.

Connect to the base of the transistor (7) as the battery (
The transistor (7) is turned off while the voltage of the battery (2) is low, and when the voltage of the battery (2) increases and reaches the charge setting voltage, the transistor (1) is turned on.

列に入らない効果は顕著である。Since the control element is not connected in series with the charging circuit Cζ, the output voltage of the solar cell is not reduced and the charging performance is improved. This is especially true when the four cell voltage is low (or when trying to reduce the number of solar cells), the effect of not connecting the control element in series is remarkable.
