Wireless charging system 210W specification
◆ Please note that the signal may become unstable (false signal or chattering) when the transmission distance
and the center offset are outside the specification range.
◆ The inzone signal is a preliminary signal for confirming that the output signal is established within the specifi-
cation range. Please note that it does not guarantee signals output outside the specification range.
About the battery voltage monitoring for charging
A "battery voltage monitor function" is a function which a charge unit monitors battery voltage, and
changes and outputs to three kinds of 【voltage monitor signals】.
A【voltage monitor signal】 is outputted from both a power supply unit and a charging unit.
Battery voltage monitor's timing differs <charge> <non-charging>.
<Signal output time required>
Up Inzone signal lights from entering the head transmission area : 5s or less
To start charging from the Inzone signal lights : 5s or less
【Electric supply starting signal】After ON, if active head and passive head enter in a transmission
domain (in zone), a 【in zone signal】 turns on, monitoring of battery voltage is started and a【voltage
monitor signal】 and a 【charge signal】 turn on. During charge, battery voltage is always monitored
and the 【voltage monitor signal】 suitable for battery voltage is outputted.
If charging current becomes below 1.5A, a [voltage monitor signal] turns off, a [float charging sig-
nal] turns on, and it will be in an float charging state.
Below, I shows the timing chart example of battery level monitor function during charging.
