LI-ION BATTERY AVAILABLE CHARGE GAUGE : System Description

SYSTEM DIAGRAM
DESCRIPTION
• LBC transmits a Li-ion battery available charge signal to VCM via EV system CAN communication.
• VCM transmits a Li-ion battery available charge signal to the combination meter via CAN communication.
• The combination meter indicates the Li-ion battery available charge to the Li-ion battery available charge
gauge according to the Li-ion battery available charge signal received via CAN communication.
NOTE:
• Li-ion battery available charge signal is a signal which requests the number of lighting segments of the Li-ion
battery available charge gauge. The number of lighting segments is judged by LBC, according to Li-ion bat-
tery available charge level. When receiving a Li-ion battery available charge signal, the combination meter
shows the number of lighting segments requested via Li-ion battery available charge signal on the Li-ion bat-
tery available charge gauge.
• Li-ion battery available charge level is displayed by the ratio to the full capacity.
• Since Li-ion battery capacity changes with Li-ion battery temperature, the indication of Li-ion battery avail-
able charge gauge may change.

Since the indication method of available charge level is different between Li-ion battery available charge
gauge and quick charger, the above Li-ion battery available charge level (%) does not agree with levels dis-
played on quick charger.
