8.5 SOC Algorithm
The MCP calculates the SOC of the eBick system at all times by coulombometry,
including the internal consumption of its own electronics. To avoid accumulated errors,
you have several points to update the charge status at different levels:
1. 100% update - Regardless of the SOC shown on the screen if the series voltage
levels (in the CHARGE process at a certain current) reach a certain voltage value
the SOC automatically changes to 100% since the MCP interprets that the
system is really charged at that level.
2. 5% update - Regardless of the SOC shown on the screen if the series voltage
levels (in the DISCHARGE process at a certain current) reach a certain voltage
value the SOC automatically changes to 5% since the MCP interprets that the
system is really discharged at that level.
3. Without current (OCV)
– Regardless of the SOC shown on the screen if the
series voltage levels (in the IDDLE process, current 0A) reach a certain voltage
value after a stabilization time the SOC automatically changes to the value
indicated in the algorithm since the MCP interprets that the system really is at
that level. This update is only for SOC values below 30%
8.6 Alarm reset
There is a differentiation between the devices connected in parallel to 48Vdc (MCP
Parallel) and the equipment connected in series (MCP serial) for the alarm reset process.
MCP Parallel
– Parallel equipment has a CONNECTED preload system to automatically
connect in case of alarm recovery. That is, the equipment is autonomous in the
reconnection (alarm reset) of the system. For the connection it has a number of attempts
(3) in case of not being able to do it due to a problem, the device will go to error indicating
the alarm on the screen.
Note: There are two alarms that do not have the reset process as it is understood that
they are important from the point of view of system security. They are related to the
voltage difference and temperature difference. If in any case the difference in voltages
or temperatures exceeds a certain value for each case, it is understood that there is a
damaged cell or probe (voltage or temperature) and the process of automatic reset of
alarm is eliminated.
MCP Serie
–
Serial equipment has the preload system DISCONNECTED, so it is
necessary that the inverter indicates the reconnection of the power by communications
when the bus is safely preloaded and the battery has no alarm on screen.
