Re: [TRNSYS-users] bug in battery component

Thank you Jef for your quick respons. However, isn’t it the other way around? If an input is unconnected, “string” should be checked and the default is used. But if it is connected, shouldn’t the input that is selected be used? Or is it the other way around and does “string” need to be selected when an input is connected?

 

Kind regards,

Egon

Changing units of an input only changes the value of any UNCONNECTED input.  Connected inputs are always assumed to be the default units that the component expects.

Hi,

 

I found a bug in the TRNSYS 17 battery component “Type 47a”.

 

When changing the unit of the input “power to or from battery” to “kW” it still reads the input as if it were kJ/hr. This results in an unrealistic state of charge as if the battery is much too large.

 

If any questions, don’t hesitate to ask!

 

Kind regards,

Egon
