Our plans were to race the Saturn back when it had the lead power pack a couple of years ago. I never got around to it. So this year with the Lithiums, I made time for it this July 3rd 2011. We chose Gleason, TN drag-strip because they run ‘street car’ bracket racing on Saturday…
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…
June 5, 2011 started driving the Saturn again with the LiFePO4 CALIBs. After 3 weeks I have recorded the results. Notice how the effeciency changes. One cause is the charger is not consistant. Sometimes not fully charging. So far I have not seen it overcharge. When recording the voltage I have not seen it go…
The results are in. After driving the Saturn a week it does seem like a new car. Quicker, no sulfur smell or acid, lighter, double the distance and easier to steer(front end lighter), from the first half mile drive to the one Saturday June 11 of 61 miles. The vehicle is much lighter. We removed…
Batteries are installed. Forty Eight of them, CALIB 130 ah at 3.2 volts each comes out to 153.6 volts. 182112 is the odometer reading when the Lithium batteries are installed and the key turned on The old pack was lead acids 18 of the 8 volt golf cart deep cycle Exide 150 ah running 144…
Changing over from the lead acids to Lithium in the LiFePO4 (lithium iron phosphate) format included different requirements physically. –Physical Differences– * Require one third less space * About half the weight * Most will be strapped with copper bars which have little flex * Batteries can swell when discharged or charged quickly and damage…
Well, I decided on CALIB batteries because of discussions on http://www.diyelectriccar.com and http://www.evdl.org/archive/index.html . Specifications Model:SE130AHA Keegan Han is the manager at Calib Power Inc. The company is a quisi-China government company, like a retail outlet for CALIB . I emailed him and he quickly replied. We emailed a few more times and talked on…
The following table is a list of lithium phosphate, electric car suitable, available and beyond the testing phase batteries. As before, there are NO USA lithium battery companies selling to the independent EVers. ———————————— Brand Distributors Manufacture Info Wilson (Thundersky) Lithiumstorage AllianceRenewableEnergy EVolveElectrics CurrentEvTech Winston Battery Limited, Shenzhen in PRC, China GBS RebirthAuto ElectricMotorSport…
LiFePo4 Battery Price Comparisons November 2010, Non-West Coast USA Since the old battery order will not ever arrive, lets start over again. Price comparison and deliver time and trust factor. I will edit this list if more info needs including. Not going to do it I am not going to do these 3 things again…..…
