8 Working with the eBick
8.1 Precharge
There is a differentiation between the devices connected in parallel to 48Vdc (MCP
Parallel) and the equipment connected in series (MCP series) for the
connection
process.
MCP Parallel
– Parallel devices have a CONNECTED preload system to connect
automatically. That is, the equipment is autonomous in the connection and reconnection
of the system. For the connection it has a number of attempts in case of not being able
to make it, the device will show an error indicating the alarm on the screen.
MCP Series
–
This equipment has the preload system DISCONNECTED, so it is
necessary that other equipment (inverter or similar) indicates the power connection by
communications when the bus is safely preloaded.
8.2 Charging
The eBick system always works with CAN BUS communications with the inverters. In
this way the MCP always communicates to the inverter the charging voltage and the
maximum charging current that must be respected at all times, depending on variables
such as the state of charge of the battery (SOC) and the temperature of the cells. In this
way, depending on the charging conditions, we optimize the process to preserve the
safety and life of the batteries. This is known as the SOF (
State of Function ) function.
