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.
Updated 2020 All Electric Vehicle Efficiency & Emissions This article, by Collyn Rivers, discusses electric vehicle efficiency and emissions. All road vehicles emit pollution (and are health issues). Emissions are in two main forms. One includes haze and...
Updated 2020 Electric vehicle motors AC/DC Electric vehicle motors use one or other of the two main kinds of electricity: alternating current and direct current. Both are effective as electric vehicle motors. Alternating Current (AC) is where electric current...
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.
If connected incorrectly, solar regulators with current shunts can register twice your true solar input. Here’s why – and how you can to fix it.
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 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.
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.
You can make RV solar and alternator charging work. It is complex on post-2014 vehicles. This ongoingly updated article explains how.
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.
Updated 2020 How much solar capacity do I need This article answers how much solar capacity do I need. It's valid anywhere in the world that has enough sun. It can save you a lot of money. The map below shows the amount you typically have available in Australia....
This article shows the sizes and lengths of electric supply cables for caravans and motor homes legally required in Australia and NZ.
Speeding battery charging from generators is cheap, effective and relatively simple. This article by RV Books’ Collyn Rivers explains how to do it.
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.
Battery charging and battery chargers are often misunderstood – causing batteries to die before their time. This article explains why and how to avoid it.
Twelve-volt caravan systems may be twin-wire or chassis return. Twin-wire is usually best. This article explains why – and which to choose to avoid problems.
Connecting caravan batteries is often misunderstood. This article explains what’s possible, and why and how to do it successfully.
All lead acid batteries, AGMs and gel cells, generate explosive gas. Even though most are sealed, makers stress that battery ventilation is vital still. Confusion exists over this. Around 2000, some battery makers began to claim that no ventilation was required. Or, ventilation, is advisable but not necessarily essential. They withdrew this advice, however, shortly after. Many batteries thus have a warning notice as below.
Variable voltage alternator problems with caravans and motor homes arise when charging auxiliary batteries. Here’s why and how to fix them. These alternators are, in particular, installed on many post-2013 vehicles.
TV interference from LEDs is an issue worldwide. It is mostly caused by LEDs in the same home (or RV) as the TV. This can be checked by turning them off. Another indicator of TV interference from LEDs is good daytime reception until lights are turned on. In the worst cases, TV reception is unwatchable, or not even obtainable.
