I don't take the bus out much, if ever, in the winter. The only problem with liths is charging when below freezing. If your batteries are in the living space they should get no where near freezing. Basically a tiny mini-split? The first problem I see would be in the summer time, adding more heat to the battery box. Interesting idea, I hadn't seen that kind of set up before. It's easy enough to change the charger for lead acid and then back. I think, I'm going to run the liths down about half way and disconnect them, then hook up a lead acid. One thing about the fancy inverter/chargers with AC pass through is that they wont turn on unless they "see" DC voltage. While I don't really take the bus anywhere in the winter I am still working on it and need power all winter. Besides the heat pad, which is set to come on about 38☏ I also have a total disconnect of the batteries from everything set at about 35☏. I'm just using the heat pads to make darn sure the batteries never get charged when they are below freezing.
PORON polyurethane material is designed to reliably hold a consistent force, keeping battery cells aligned, sealed from dust and fluid and isolated from the damaging effects of vibration.Click to expand.Interesting idea, I hadn't seen that kind of set up before. Gaskets fabricated from BISCO silicone material seal out water, dust and debris while providing exceptional temperature and UV resistance. Battery Enclosure Sealing and FasteningīISCO silicone foams are the solution of choice for sealing and protecting battery enclosures from potential damage caused by the elements and road debris. The C-set of these unique materials withstands collapse caused by the stresses of compression and temperature over time, extending the life of the battery by continuing to seal and absorb shock. PORON polyurethane and BISCO silicone anti-vibration pads are proven solutions within the automotive industry, providing solutions as vibration dampeners and isolators.
Vibration must be managed both within the pack and between the pack and the vehicle. Anti-Vibration Pads for Vibration Isolationīatteries also need to be packaged to absorb internal impact energy. PORON material pads and silicone battery compression pads enable the designer to predict the material’s behavior across varied dimensional tolerances. Battery pads made from PORON polyurethane and BISCO silicone foams have a unique ability to produce a very consistent level of force across a range of compressions. Reliable compression set resistance (C-set) and stress relaxation performance over a broad range of temperatures and conditions is critical. Battery Compression Pads and Cushionsīattery Pad cushions, or compression pads, used inside an EV pouch cell battery pack must be firm enough to hold components in place and compressible enough to withstand dimensional changes to the pouch cells over the life of the battery.
PORON® polyurethanes and BISCO® silicone materials are designed to reliably hold a consistent force, keeping battery cells aligned, sealed from dust and fluid and isolated from the damaging effects of vibration. Rogers’ suite of battery pad solutions is designed to provide designers with high-performance options that can withstand the stresses of fluctuating compression and temperature. Lithium-ion (Li-ion) batteries, the power source of choice for the new generation of electric, hybrid, and plug-in hybrid vehicles, require cushioning, sealing and vibration isolation that must perform reliably under tough conditions.
