7.2.1. Charging Technology
The trak | systemizer dynamics storage system is fitted with intelligent charging
technology which has been specially adapted to the battery technology used in order to
maximise service life, uptime and efficiency. The charging processes in accordance with
DIN 41773-1 must only be used in a modification permitted by the manufacturer
HOPPECKE. Operation with other chargers not authorised by HOPPECKE is not permitted
as this can significantly impact on the service life of the storage system.
The 1:1 correlation of battery storage and charging technology makes it possible to
optimally adapt the charging management to the storage system requirements. Typical
recharge times at 70% discharged capacity are listed in relation to the permitted charging
currents in the following table:
