The market for quickly-rechargeable, light and compact batteries is huge. One or another battery will eventually evolve. When it does, electric-only vehicles are likely to have a range unthinkable using fossil-fuels. Moreover, in the meantime, hybrids are an excellent compromise. Furthermore, see also Electric Vehicles – Hybrids.
Batteries & Battery Charging
Electric and Hybrid Vehicles
Globally, there is move to electric vehicles. Apart from minor rubber tyre particles they are virtually emission free.They are also about 80% efficient. If, however, their electricity is from fossil-fuelled power stations, their emissions are similar to year 2020 petrol-fuelled (or hybrid) vehicles.
Baghdad battery myth
In the 1930s, German archaeologist Wilhelm Koenig claimed that whilst excavating an archaeological dig near Baghdad (Iraq), he uncovered a small clay jar. It had a plug that sealed the opening. That plug had a copper tube with an iron rod inserted into it. If filled with an acidic liquid, the device functioned as a basic battery. Koenig and others made similar versions that generated up to two volts per unit.
Lithium battery rival
Lithium-ion and lithium-iron-phosphate (a lithium battery rival) are two types of rechargeable batteries. They share some similarities but differ in high-energy-density, long life-cycles, and safety. Lithium-ion is used in smartphones and laptop PCs. Lithium iron phosphate (LiFEPO4) is that used in RVs etc.
Lead acid batteries for travel trailers – they are still a good buy
Lead acid batteries for [caravans] are still a viable buy. They are made in different shapes, sizes and capabilities. All work in a basically similar way. Energy is stored within them as a result of electro-chemical reactions between lead plates and a water/acid mix (called electrolyte). They are charged by imposing a voltage across them that is greater than the voltage ‘within’ them at the time. The greater that voltage difference the quicker and deeper batteries charge. When battery voltage reaches the charging voltage, charging ceases.
Generator Battery Charging – Quickly and Deeply
Battery charging quickly and deeply by a generator is very possible but only if you know how it has to be done. This article shows why and how.
Blade fuse problems in travel trailers – they may burn or melt
Blade fuse problems in [caravans] include fuses and fuse holders burning or melting. Fire risk is high because the fuses may continue to conduct. Ongoing current flow, however, may heat the fuse holder to burning point. This article by RV Books explains why and how to overcome the risk.
Lighting for travel trailers – it makes every sense to install LEDs
Lighting for [caravans] has changed. Now, by far the most practical and least energy drawing are LEDs (light emitting diodes). This article shows why.
Fast battery charging from generators – cheap, effective and relatively simply
Speeding battery charging from generators is cheap, effective and relatively simple. This article by RV Books’ Collyn Rivers explains how to do it.
Dc-dc charging – how to speed alternator charging
Initial charging of a deeply discharged battery is generally limited to a basic dc-dc charger’s capacity: not the alternator’s. Dc-dc chargers under 20 amps thus usually take longer to charge close to flat batteries to half charge. Thereon, charging is hugely faster.
