LI-ION BATTERY AVAILABLE CHARGE GAUGE : System Description

INFOID:0000000010122394

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.
