I just got a Prolong charger discharger Kit for my 2010 Regular Prius. My first cycle of charge/discharge/charge end battery pack voltage was 236V. I drove it to work, after sitting overnight. I think the first 4-5 miles was very detrimental. Here is my reasoning. I had Dr Prius battery monitor on and notice the car didn’t know the SOC right away. The car kept charging the battery about 4-5 miles. Because the cells were at full capacity and being charged rapidly, the temps were higher than they normally were in the morning +110F (normally 90-100F). And the Voltage Indicator was constantly turning red! In my minds eye, I was imagining the cells being overcharged and venting! I think this stage (First 4-5 miles after full charge) is very detrimental. Next time around I’m thinking of discharge slightly around (225-230V). What do you guys think?
