2.6 CHARGER

SMART CHARGER

The integrated EnergyPaks require the Smart Charger. The high charge cur-
rent (up to 6A), the advanced BMS in the batteries and the "smart" capabili-
ties of the charger make it possible to charge the battery very quickly, yet also
optimize battery health and lifespan.
In MY20 a new Smart Charger version is added, with an 90 degree angled
charge plug. It functions exactly the same as the existing Smart Charger, but
this charger works only with 220V AC outlets. It can charge all existing MY19
and MY20 Integrated batteries.
The Smart Charger can charge the battery when it is still in the bike, by con-
necting it directly to the integrated connector in the bikeframe. MY20 bikes,
that are compatible with EnergyPak Plus, have a charge socket with 2 extra
pins. These 2 extra pins allow the EnergyPak Plus to connect the bike. Both
straight and angled 5-pin smart charger plugs fit into this socket. For charging
the battery when it's removed from the bike, the Charge Adapter (147L-
HDC000-02) is needed.
The first stage of the charge will have a high speed using the maximum 6A
current. The Battery Management System works together with the charger to
monitor the battery cells temperature, and other health indicators. When cer-
tain cells are getting too hot or otherwise less than optimal, current is reduced
or diverted to other cells.
During the final stage of the charge, the overall charge current is reduced to
balance and equalize the cells and reach the 100% charge at a steady pace.
This charging process optimizes not only each individual charge, but also
continuously adapts as the battery ages, extending the lifespan of the battery.

STORAGE MODE (60% CHARGE FUNCTION)

For long term storage, a 60% charge level is optimal for the maximum
lifespan of the EnergyPak. The Smart Charger has this functionality built-in. It
works and behaves exactly like a regular charge, except it is needed to acti-
vate the storage charge mode by pushing the LED2 button.
During storage charge, the LED2 button will light up (yellow) and the normal
led sequence will be visible on LED1; First blinking green while charging, then
constant green when the storage charge to 60% is completed.

STANDARD FAST CHARGER

The Standard charger is compatible with all the other MY19 EnergyPaks; The
Side Release, Top Pull and Carrier EnergyPaks. It has a 3-pin charge con-
nector and can charge the batteries on or off the bike. Charge times are still
relatively fast. There are versions for 220V, with a max. charge current of 4A,
and for 110V, with a max. current of 3A
