Battery Cell and System was created by Alejandra
Good morning,

I am trying to model the battery RESU10H Type-R manufactured by LG Chem in SAM. However, it is a high-voltage battery and I am concerned about which voltage should I choose. The nominal voltage is 155 V (9800 Wh/63Ah), but the voltage range is 350-450 V. I guess the battery has a voltage converter or something similar inside. 

Which values should I enter in the current and capacity section? I have included a screenshot of my current values, it is a Lithium Ion NMC battery.

Kind regards,
Alejandra

Hi Alejandra,

For the Resu10H Type-R battery, set the desired bank voltage in SAM to a value between 350 and 400 VDC. The data sheet does not provide information about cell voltage and capacity, so you can leave those at their default values of 3.6 VDC and 3.2 Ah, respectively.

You can set the desired bank capacity in SAM to 9.8 kWh, and the desired bank power to a value that is suitable for your application. The desired bank power is the maximum discharge power, so you might set it based on the load, or based on the number of hours of storage you need (nominal hours of storage = bank capacity (kWh) / bank power (kW).

Best regards,
Paul.
