Electric vehicles do not have the waste heat energy that ICE’s do. An auxiliary form of heat must be added. Here are some of the ways we are trying to do that. Also air cooling methods are experimented with.
Testing a thermoelectric air conditioning system. Will try some things, see if it is practical enough to install in the EV Saturn. 12 Peltier Chips Arranged: Arranging the chips different ways to get 12 on the available heat sink surface.Fiberglass Frame: Fiberglass Frame that will hold the Thermoelectric Machine and bolt to the EV First…
Thermal Paste heatsink compound should be removed and new put on when working with the Peltier module. The stuff is sticky. You can use acetone, isopropyl alcohol (rubbing alcohol) or ethanol alcohol (get denatured cause if not denatured you might take a swig when you get frustrated). I used rubbing alcohol and coffee filters. Coffee…
The Thermo-Electric Peltier Effect air conditioning project has begun. I removed the Saturn dash. This is the third time and probably not the last. The first 2 dash removals were to install the [[http://saturn.lynnautorepair.com/node/189|hot water heat system in 2008]]. The second time was to [[http://saturn.lynnautorepair.com/EV%20Hot%20Liquid%20Heater%20to%20a%20Ceramic%20Heater|change the heater to a ceramic style in 2009]]. Now the…
I purchased 2 thermoelectric chips with hot and cold heat sinks. Testing them I found they pull 4 amps at 11.75 volts, so about 50 watts each. Junction Cold Side: Cold Side Thermoelectric Heater Cooler Peltier Junction LWKW-0318 With a air cooled heat exchanger working on the hot side removing the heat. The non-contact thermo-sensor…
Background: A Peltier effect, thermoelectric device creates a temperature difference when a voltage is applied to it. The device is also thermodynamically reversible. When the poles are reversed the hot side becomes the cold side and vice-versa. Also these semiconductor devices have the Seebeck effect. Seebeck is the conversion of temperature differences directly into electricity…
As I posted earlier and I made a decision to change out the liquid heater to a ceramic heater and [[http://saturn.lynnautorepair.com/2009%20Summary|gave the reasons why.]] Liquid Heater Parts Removed Have removed the dash, dropped the column, removed the complete heater HVAC housing and all of the old liquid heater system, tank, hoses, relays and motor. Removed…
The Liquid type heater I used verses a ceramic heater was an involved deal. I purchased the components from www.EVAmerica.com at a cost of $500. It was made by Classic Electrics http://www.classicelectrics.com . The components include the: heater box, pump, coolant reservoir, contactor, Anderson SB-50 disconnect, fuses, relays and some mounting hardware and hoses and…
