Master Remaining Capacity: this is relative to what value? Is it in mAh or some kind of
percentage/ratio?
The Master Remaining Capacity is in mAh unit. FCC / RC = SOC
TPDO9: What are the conditions for the TPDO9 to be transmitted by the master battery?
The battery will send the PDO9 as soon it recognizes a heartbeat from Node ID 100dez (charger) and
when the charger is configured by the battery via SDO read/write requests. When the charger sends
its “Extended Charger Status” Bit with value “1”, the Charge FETs of the battery will be closed.
Is the TPDO mapping feature of CANopen functional?
No, the battery modules do not support dynamic PDO Mapping at the moment.
If I remap the values to other objects do the batteries comply with the remapping and may I do
that for TPDOs 5 to 8 without compromising any of the batteries functionality?
Unfortunately, the system is not designed to support any external change of PDO configuration.
Are the SDO steps compulsory or is there a way to jump immediately to PDO-based
communication?
Currently the SDO transfer is mandatory. Otherwise the battery will get stuck in SDO write errors
Will the battery perform SDO interactions with the charger even after PDO communication starts?
No, it will not.
13.4 Parallel Connection
Is it possible to add additional modules in parallel, after the system is already configured?
Yes it is possible. Please switch the batteries off before adding modules. After adding modules, start
the system again. In case of orange blinking LEDs, press the push button of any battery for at least 5s
to reconfigure the Node IDs.
Is it possible to connect 4 systems in parallel, if a system has 6 modules already connected?
Yes, it is possible. The module state has to be in OFF mode, while you connect the additional
modules. As soon as the modules switch to ON mode, the master will be defined. If LEDs keep
blinking orange, the push button of any module needs to be pressed for at least 5s.
13.5 Safety / Life time
Can the modules turn off while operating?
Yes, this will happen in case the protection is triggered.
What factors affect the total lifetime of the battery?
The total lifetime of lithium ion batteries in terms of both calendar life (age) and cycle life (number of
full charge/discharge events) is affected by many factors. In general, the more “gently” a battery is
