FREQUENTLY ASKED QUESTIONS
Answered by AMP Experts
A Fast Charge Junction Box, also known as a DC Fast Charger, is an electrical device used to provide high-power DC charging for electric vehicles. AMP FCJB is a combination of a charge controller with DC contactors in a single unit, backed up by AMP’s proven software stack for EV charging.
The FCJB (Fast Charge Junction Box) communicates with the charging station and identifies the charge communication protocol needed. It communicates the voltage and current requested by the BMS to the charging station while monitoring communication with the charging station and EV ensuring proper connectivity between the two. In case of any communication breach, it safely disengages the vehicle from the charging process. It also incorporates the control of the DC charging contactors for electric vehicles.
The operation of the DC fast charge contactors is brought into the FCJB reducing the need for external contactors and monitoring the charge sequence. It has inbuilt software capabilities to control the DC contactors, making it a combined unit.
Yes. The FCJB is typically compatible with any electric vehicle that allows DC fast charge capabilities.
AMP FCJB monitors the internal temperatures of the high-voltage components to prevent any thermal event. It also monitors the EV inlet temperatures and ensures safe operations. It controls the locking of the inlet at the vehicle side to ensure the charge station connector cannot be removed during DC charging and makes sure that the vehicle is stationary during the charging process.
The EVCC communicates with the charging station to identify the needed charge communication protocol. It relays the BMS’s requested voltage and current to the charging station. It monitors communication with the charging station and EV ensuring proper connectivity between the two and if there is any communication breach, it safely disengages the vehicle from the charging process.
AMP FCJB is completely future proof. It is compatible with ISO 15118 -20 enabling di-directional charging (V2G). It can support the grid by supplying power back to it when needed.
