Charging
In aircraft charging
The HV batteries can be charged at own risk inside the aircraft using the following process:
1. Remove the terminal plug and connect the charger plug to the charge port in the
fuselage.
2. Insert a terminal connector to Cable B of the battery charger.
3. Turn charger ON.
4. Within 20 sec after the charging process is initiated, the DCU offers two additional charge
options:
• Limiting the charging power; or
• Switching to winter charging

Once the charger is connected, 12 V power is supplied to the battery manager, IMD, and DCU.
The battery manager starts the charging process by activating the HV relays with the DCU
monitoring the process.
Once batteries are fully charged the battery manager switches off the charging process and the
DCU displays the standby screen.
If a single battery is charged inside the fuselage, the terminal plug must be inserted in the male
connector of the removed battery, as illustrated in Figure 10-6.
