(2) Battery Protection Function
The temperature of the battery during charging significantly affects the life of the battery.
Therefore, the charger controls the charging based on the battery temperature data that is sent by
the battery management system.
• The temperature of the battery at which the charger can start charging is
between 0 and 40°C.
• The charger will abort charging when the battery temperature exceeds 50°C.
NOTE
The power will turn OFF automatically after 12 hours even if it is connected.
NOTE
• Immediately after the wheelchair has been driven or due to the ambient
temperature, the battery may be out of the temperature range (0 to 40°C) that
is suitable for charging. Charging the battery in this state will accelerate its
deterioration. In this case, the system will shift the battery protection function
to set the charger in the standby mode until the temperature of the battery
comes within the specified range.
• To bring the temperature of the battery within the specified range (0 to 40°C),
move it to a location with an appropriate temperature. Wait a while before
charging. (Charging between approximately 10 and 25°C is recommended.)
