Ensure that the battery is equipped with a suitable and adjusted BMS and that the conditions for any of the following two alterna-
tive charging process- es are met.
Alt 1. BMS controlled charging by use of serial communication and analog control. Ensure that the charger is adjusted for
correct:
• Serial data communication
• Analog I/O functions (if used)
Alt 2. Charger algorithm driven charging, monitored by external BMS.
Ensure that the charger is adapted for the battery type. Check, confirm, and if adjustable, set the following for each individual
battery type before charging:
• Charging curve
• Number of battery modules
• Battery capacity (Ah) • •
• Analog I/O functions (if used)
LITHIUM-ION BATTERY SAFETY SYSTEM
WARNING
RISK OF BATTERY DAMAGE! - Read and follow the precautions provided below:
Charging of lithium-ion batteries may only be per- formed when a, for battery and battery charger, approved safety system for
battery monitoring and module balancing is connected and active.
The complete system is further referred to in this manual as a BMS system (Battery Monitoring System).
The BMS system must:
1 Monitor and protect the battery so that no hazardous conditions can occur when charging or using the battery
2 Monitor and balance each individual series- connected module in the battery
3 Disconnect the battery from the battery charger and power load, in accordance with applicable national standards, before a
hazardous situation may arise
4 Ensure that each individual module is balanced with considering voltage and charge level
5 Operate automatic without the need for manual monitoring
The battery chargers covered by this manual do not have their own integrated BMS system.
All use of battery chargers covered by this manu- al requires that an external BMS system is con- nected and active during all
charging and use of the battery. The BMS system must be automatic and approved for battery and battery charger.
Even if a battery charging curve for lithium-ion battery is selected and adjusted in the battery charger, an external BMS system
must be connec- ted and active during all charging and use of the battery. The BMS system must be automatic and approved for
battery and battery charger.
• Ensure that the battery's limitations according to its data sheets are not exceeded during charging or use. Note that the restric-
tions apply to each module in the battery
• Charging lithium-ion batteries must not be per- formed if the modules have a temperature lower than 0 °C
• The lithium-ion modules to be charged should have a uniform temperature
• Battery modules must not be hermetically enclosed in external housings without proper ventilation being ensured
