Lithium-ion Battery Model

Hello,

I am new to PSpice. I have a Lithium-ion Battery Model. I already built in PSIM, and I tested it. It is working there. Now I have built it in PSpice. it is also working except for one issue. To check, I placed a resistor as a load, and I saw from the SOC that the battery is discharging. I also tried to place a current source to charge the battery, and the battery was charging. However, when I tried to place a current source to dischgarge the battery, I got a message says" There are no data values in section number 1 ignoring this section". When I go through the results to see the error, it tells me there is "INTERNAL ERROR -- Overflow, Multiply". 

I still don't know what to do to overcome this problem. Could you please help me solve this probem?

Thank you,

Ahmed
