Ideal charging system in this class with the following installations
* Controlling by micro computer : The installed micro computer perceives the full charged condition, and
A) Minus delta V system : Stop the charging process with perceiving the battery's voltage drop.
B) Delta T system

* Current transforming system : The built-in "High-Frequency Tranceformer"supplys the charging current as follows.
* Constant output current (charging current)
* Trickle charging mode : Continue to produce very small charging current (approx. 40mA) for full charged

control the optimum way to stop the charging process, from the followings.
: Stop the charging process with perceiving the change of battery's temperature.
( This system is applied to only the charger of 4 terminal-type.)
: Stop the charging process with perceiving the battery's temperature which is
input in the micro computer in advance. For instance the charging process is to
be stopped at 45°C for 1.3Ah battery, and at 60°C for 1.7 - 2.2Ah battery.
: Stop the charging process in 150 minutes after starting the charge, if the full
charged condition would not be perceiving with any of the above 3 systems.
Full charged line
1. Convert alternative current into direct current.
2. Re-convert the above direct current into alternative current, however, high
frequency of approx. 150 - 160 kHz in this stage.
3. Reduce the voltage to the battery's voltage.
The feature of "High-Frequency Tranceformer" is light and compact comparing
with the existing trance.
: By keeping the output current (Ampere) in the constant level, it is possible to stop
the charging process with perceiving the battery's voltage drop exactly.
Namely it is possible to perceive the full charged condition by the above
"Minus delta V system ".
