Combination Meter






VCM controls the following items on the combination meter in addition to the warning lamps and indicator lamps.

LI-ION BATTERY INFORMATION

Li-ion Battery Capacity Level Gauge (1)
VCM receives the Li-ion battery capacity signal from the Li-ion battery controller, and VCM transmits the signal to the combination meter to display the maximum capacity of the Li-ion battery. When the capacity of the Li-ion battery decreases with age and usage, the level of the gauge is also decreased.
Li-ion Battery Available Charge Gauge (2)
VCM receives the Li-ion battery available charge signal from the Li-ion battery controller, and VCM transmits the signal to the combination meter to display the available Li-ion battery charge to run the vehicle.
Li-ion Battery Temperature Gauge (3)
VCM receives the Li-ion battery temperature signal from the Li-ion battery controller, and VCM transmits the signal to the combination meter to display the Li-ion battery temperature.
Distance Range (4)
The driving range (km or miles) provides an estimated distance that the vehicle can be driven before recharging is necessary. The driving range is constantly being calculated, based on the amount of available Li-ion battery charge and the actual power consumption average.
VCM calculates average electricity consumption at a specified travel distance, according to total power consumption of the vehicle. Based on the average electricity consumption and the Li-ion battery available charge signal received from the Li-ion battery, VCM calculates driving range and transmits a driving range signal to the combination meter.

POWER METER

Maximum Power (5)
VCM receives a maximum motor output power signal from the traction motor inverter and a maximum regenerative power signal from the Li-ion battery controller. VCM transmits these signals to the combination meter and displays the upper limit of available output power and regenerative electric power.
Current Motor Power (6)
VCM receives the current motor power signal from the traction motor inverter, and VCM transmits the signal to the combination meter to display the power currently being output.
