のように直列状態で行うのが好ましい。Thus, in the present invention, the first and second battery groups (20) (21)
Charging is performed in series, a uniform charging current is supplied to each battery group, and each battery group can be charged in the same state. On the other hand, if each battery group is charged in parallel, the state of charge of each battery group (for example, the difference in the internal resistance value) becomes uneven, and in extreme cases, a large current flows to one battery group. It may flow and cause thermal runaway. Therefore, it is preferable to charge the first and second battery groups (20) and (21) in series as in the present invention.

2) (23) (24) is turned on to the second contact (22b) (23b) (24b) side, and the first and second battery groups (20) (21) are connected in parallel to the fan motor (6). Since the power is supplied, the fan motor (6) can rotate at a low speed to obtain a weak suction force.
At this time, a high voltage is applied to the first and second battery groups (20) and (21) when the charging plug (16) is still connected, but the operation switch (7) is a rebound type, so the pressing is released. If it does, the problem due to high voltage does not occur and the battery group (20) (21)
Will not be adversely affected.

要がないので軽量化できる。(G) Effect of the Invention According to the present invention, the first, second, and third battery groups are switched by the first, second, and third switches that are switched in association with the strength of the suction force by the operation of the operation unit of the operation switch. Since switching between series connection and parallel connection is performed and resistance is switched, there is no unnecessary power consumption as in the conventional example, the battery can be used for a long time with one charge, and a heat radiating means is not required, so that the weight can be reduced. .

できる。Furthermore, these first and second battery groups are connected in series at all times, that is, when the vacuum cleaner is not used (in other words, when the first, second and third switches are open), each of these batteries is connected. The charging of the group can be reliably performed in series. Therefore, when charging each battery group in parallel, the charging state becomes uneven due to the state of each battery group (for example, the difference in internal resistance value), and in extreme cases, a large current flows to one battery group. The charging current can be evenly supplied to each battery group without fail to cause a problem such as thermal runaway, so that the battery can be fully charged reliably.
また操作スイッチを跳返り型のスイッチにすれば、不使
用時に第１、第２電池群を並列状態のまま放置すること
がなく、さらに並列状態のまま充電することもない。If the operation switch is a flip-back type switch, the first and second battery groups are not left in the parallel state when not in use, and are not charged in the parallel state.
