When many electric vehicles charge at the same time, load balancing can be necessary to prevent overload. If there is an overload, the system automatically adjusts the power of the charging stations or stops them completely. Configuration instructions CTEK E-Mobility AB... -
Page 3: Installation Procedure
The most important configuration is the configuration of the NANOGRID™ controller unit. The NANOGRID™ controller unit has two variants: • CTEK GRID CENTRAL (CGC): A controller unit that is dedicated to the task of load balancing. The control unit is usually installed in a separate cabinet. Distribution Panel •... -

FIFO: First in first out scheduling. The EVSEs with the longest charging session are prioritized. SIMPLEFEEDBACK: A feedback-based scheduler that can be abbreviated as SFB in nanogrid.ini. This is the recommended scheduler. • Set the scheduler parameter at the top-level category to select scheduler.

Setup: Distribution Board MAINPANEL 50 A with 4 EVSEs. Total available capacity is calculated (TotCap). STATION_1: EVSE1 (16 A) Each charging EVSE gets assigned (TotCap/Count) Ampere. STATION_1: EVSE2 (16 A) STATION_2: EVSE3 (16 A) STATION_2: EVSE4 (16 A) Configuration instructions CTEK E-Mobility AB... - Page 13 EV current draw to the controller. Assignment is done individually per phase. If an EVSE uses a single-phase for charging (either physically connected, or the connected EV only draws on one phase), that will be considered.
