I installed two cores from some ceramic heaters purchased at Lowes for $21 each several years ago. Before installing I measured output of one heater plugged into the wall with its fan on “high” as 1460W. Resistance of the two heaters in parallel was 11 Ohm at room temperature of about 85 F, and after heating with a heat gun briefly, 5 Ohm.
After installing the heater cores and putting everything back together I tested the heat output. I measured current into the heaters with an Extek EX830 meter. The pack was at about 44% SOC, and 116V. With blower on high: 27.2A, 116V, 3155W, blower on medium: 26.2A, 116V, 3039W, blower on low: 24.8A, 116V, 2877W. Possibly your cores are different resistance, leading to unequal currents through them, assuming they are wired in parallel so you have full voltage across each. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/Upgraded-heater-tp4679378p4679395.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
