VEHICLE CHARGING SYSTEM
VEHICLE CHARGING SYSTEM : System Description
INFOID:0000000010121212
DESCRIPTION
This section describes the controls related to the vehicle charging system.
PDM (POWER DELIVERY MODULE)
Description
The charger uses a 2-converter system which consists of the PFC circuit and the DC/DC converter. It
improves charging efficiency, charge level accuracy, and the service life of the Li-ion battery. PDM (Power
Delivery Module) judges whether external power supply is 100 V or 200 V, and automatically switches to
charging that is appropriate for the power supply.
NOTE:
PFC (Power Factor Correction) circuit is a power factor improvement circuit. It is a device that efficiently con-
verts AC power supply input from an external power source to a DC power supply.
Basic Charger Principle
1. AC power supply which is externally input is rectified to DC power with rectifier circuit 1.
2. The power factor of the rectified DC power supply is improved by the PFC circuit, and is boosted at the
same time.
3. The boosted DC power supply is converted again to AC power supply by the inverter.
4. The voltage of the AC power supply from the inverter is converted by the insulated transformer, and is rec-
tified to high-voltage DC power by rectifier circuit 2.
5. The rectified high-voltage DC power is output by the output circuit.

OVERVIEW OF CHARGING FUNCTIONS
Item
Description
Refer to
Li-ion battery charge control
Automatically selects a charge mode that is suitable for the ex-
ternal power source and controls Li-ion battery charging.
Charge port control
Comprehensive control for improving the efficiency of charging
work performed by the VCM.
Power voltage variable control system
Changes the DC/DC converter output inside the PDM (Power
Delivery Module) according to the VCM commands.
Automatic 12V battery charge control
Controls the DC/DC converter inside the PDM (Power Delivery
Module) according to the VCM commands, and charges the 12V
battery.

SYSTEM
There are two types of Li-ion battery charging. Normal charging converts a commercial power supply to DC
power, and quick charging uses a special charger.
For information about the charging sound system, refer to
EVC-51, "LI-ION BATTERY CHARGE CONTROL :
.
CHARGE MODE
*1: Depending on the battery state, 100% may not be reached.
*2: After charging stops, additional charging by quick charge is possible.
NORMAL CHARGE MODE
In this mode, the EVSE is connected for charging. Normal charging includes immediate charge mode, timer
charge mode, and remote charge mode.
NOTE:
The method of setting the charge level varies according to the vehicle specifications.
×: Setting available
Immediate Charge Mode
This mode immediately starts charging when the EVSE is connected. When timer charge is not set, the sys-
tem enters immediate charge mode when the EVSE is connected. When timer charge is set, immediate
charge mode can be selected by pressing the immediate charging switch.
Timer Charge Mode
This mode starts and stops charging according to the timer that is set on VCM.
NOTE:
The timer setting method varies according to vehicle specifications.
• Models with navigation without BOSE system: Refer to
AV-221, "MULTI AV SYSTEM : System Description"
• Models with navigation and BOSE system: Refer to
AV-346, "MULTI AV SYSTEM : System Description"
.
• Models without navigation system: Refer to
MWI-35, "INFORMATION DISPLAY : System Description"
.
Remote Charge Mode
This mode starts charging by remote control with a mobile device.
NOTE:
For information about operation, refer to
AV-515, "TELEMATICS SYSTEM : System Description"
.
QUICK CHARGE MODE
Mode that performs charging with quick charger. Even if charging is not completed, when the charge time set
on the quick charger or the time-out (approximately 30 - 60 minutes) set on the vehicle passes, charging
stops.
