WebDec 2, 2010 · The precharge switch is turned on first and then, after a delay, the contactor closes. This is different than the previous design because now the "on switch" (the precharge switch) can be a relatively small relay and the turn-on sequence can be easily automated to avoid closing the contactor before precharge. Here is how I did it. WebNov 4, 2001 · It allows you to keep only a certain number of cells ‘open’ or active at a time, saving power. It allows you to hide the amount of time to precharge the arrays by accessing one during precharge of another. The disadvantage, of course, is that hitting a closed bank is a performance problem….
