Product Overview

charger charger

  1. Latching mechanism - Mechanical interface to ensure a proper connection between the PowerPack and the charger

  2. Connectors - Electrical interface between the PowerPack and the charger. Used for communication and power

  3. Status indicator - Shows battery status using an LED bar; See more details below

  4. Air venting system - Active cooling ensures the product does not overheat - Attention - Do not cover!

  5. Power switch - On/off switch to turn the charger on/off

  6. Power entry - Interface for a C7 power cord to power the charger

Instructions for Use

  1. Plug attached AC power cable (C7 connector) into the charger, then into AC-socket.
  2. Turn the charger On by switching the on/off switch to On position.
  3. Mount the PowerPack into the charger. It is mounted when a “Click”-sound from the latching mechanism is heard.
  4. After initialization both modules start charging automatically. The Charging progress is displayed on the PowerPack modules.
  5. When charging is complete, the status LEDs on the PowerPack will be off and the status indicator on the charger will be all green.

Note

After the end of charging cycle, the charger automatically stops delivering power to the PowerPack. At this stage, it’s recommended to unplug the PowerPack from the charger and switch off the charger.

Status Indicator

The Status indicator consists of 3 RGB-LEDs.

The middle LED shows the charger status:

LED color Description
Off System Off
Green System Powered, OK
Red System Powered, Error

The charger error is triggered when the internal temperature of the charger exceeds 75 oC. This error will be resolved by letting it cool down.

The left and right LED shows the status of the corresponding PowerPack module.

LED color Description
Off Stand-by
Green Charging completed
Red (in a blinking pattern) PowerPack reports an error, see below

The PowerPack error blinking patterns are stated below. Please consult the PowerPack user manual for the required action(s).

Error Blinking Pattern Remark
Communication 1 x pulse + 2 sec silence The charger cannot communicate with the battery module
Cell Under Voltage 2 x pulses + 2 sec silence The module is not safe to charge due to deeply discharged cells
Cell Over Voltage or Over Charge 3 x pulses + 2 sec silence The module is not safe to charge further due to over charged cells
Over/under temperature 4 x pulses + 2 sec silence The temperature is either too high or too low
Over current 5 x pulses + 2 sec silence Charging current is too high
BMS 6 x pulses + 2 sec silence Hard fault triggered in low-level BMS.
Miscellaneous 7 x pulses + 2 sec silence Other safety error reported by the BMS, that are not related to charging.
