This is the final article in Tom Denton’s EV series. Previous articles looked at EV technologies and what is involved in repairing them. Tom also chose to be controversial at times, saying things like the hydrogen fuel cell car is not the way forward! Some of his comments below may be similar – but let’s ...

In the penultimate article in the series, Tom Denton explores the heating and cooling functions of an electric vehicle.  Most EVs allow the operation of heating or cooling when the vehicle is plugged in and charging. Some also allow this function directly from the battery. The most important aspect is that when plugged in, this ...

Wireless power transfer (WPT) is a system for wirelessly charging the batteries in electric vehicles. There are two main methods:  stationary WPT  dynamic WPT  With stationary charging, the electric energy is transferred to a parked vehicle. In dynamic wireless charging systems, the energy is transferred via a special driving lane equipped with a primary coil ...

In part one Tom Denton shared his opinion that hydrogen is not an ideal fuel for cars and looked at how clean hydrogen is created. This time, he will examine briefly how a fuel cell converts hydrogen into electricity and then compare the efficiency of an EV and a FCEV.  Proton-exchange membrane fuel cells, also ...

Hydrogen is, indeed, the fuel of the future, according to Tom Denton, just not for cars…  Whenever I get involved in a discussion about the future of transport there is often somebody who will categorically state that hydrogen cars are the only way forward. This usually arises from the idea that using a hydrogen-powered vehicle ...

Assessing the condition of an EV battery easy. However, there are two main indications we can use: state of charge (SOC), and state of health (SOH).  State of charge  State of charge is a measure of the amount of energy left in a battery compared with the energy it had when it was full. It ...

Charging an EV is clearly important. Because of this, the ‘lack of public’ charging is often stated as the reason many people will not yet buy an electric vehicle (EV). There is, however, a level of misunderstanding, among some groups, as to how and where an EV is charged. For this reason, this article is ...

The term kilowatt hour (kWh or kW-h) is often used in connection with electric vehicle batteries, but also to household electricity supply. Before I explain in detail what this means, we need to clear up the difference between a kilowatt and a kilowatt hour. Also, just a reminder, the ‘kilo’, as I am sure everyone ...

In the previous article Tom Denton described equipotential bonding (EPB) as the process of connecting all metalwork and conductive parts, of various components, so that the voltage is the same throughout these various parts (an equal potential). EPB is used to reduce the risk of equipment damage and personal injury. This time he will look ...

Equipotential bonding (EPB) is the process of electrically connecting metalwork and conductive parts, so that the voltage is the same throughout these various parts (an equal potential). EPB is used to reduce the risk of equipment damage and personal injury. It is sometimes simply referred to as bonding and is commonplace in domestic and industrial ...
