In HEVs (Hybrid Electric Vehicle), NiMH batteries are used. The energy and power are available from the battery. It is mainly measured by the SoC (State of Charging) and the temperature of the battery. The HV (High Voltage) battery conditions such as temperature, voltage, and amperage and the SoC calculations are monitored constantly by the battery ECU. The function of the HV battery is the … Continue reading How did the battery system operate in the HEVs?

One of the major concerns with PHEV is the safety of the vehicle and the passengers. Usually, a PHEV is safe in normal conditions. The high voltage and a large amount of energy are handled by the PHEVs in the battery pack. However, the safety issues occur during charging in rainy or with wet plug connectors, repairing services of the vehicle, and even during an … Continue reading Are the PHEVs safe?

Well, we all thought about converting the existing or conventional vehicles to PHEVs. If we got our conventional cars, why not convert them into PHEVs? Hybrid to PHEVs (Plug-in hybrid electric vehicles) can be done in two ways. The first method is by replacing the original battery pack (mainly a NiMH battery) with a larger battery such as Lithium-ion. The second method is by adding … Continue reading How to convert into PHEVs?

What are the ways PHEVs can be charged up in the US? One of the expensive vehicles than the conventional vehicle. But cost saving in the electrical energy front. So what are the different ways of charging electric vehicles on the road? In the USA, the PHEVs (Plug-in-Hybrid Electric Vehicle) are needed to be charged with the power grid from the utility industry. Over the … Continue reading How to use electricity for the PHEV?

PHEV is known as Plug-in-hybrid electric vehicle. Have we ever thought about the different classifications of electric vehicles? What is the purpose of a PHEV in our daily life? And when we talk about purpose. It also means the purpose for solving the daily needs of PHEVs. It has been stated that PHEVs are significantly important for environmental and economic benefits in society. The main … Continue reading What is the main purpose of the PHEV?

Well, we all know about the non-technical, political, or other such issues becoming a challenge for HEVs or PHEVs. But what about the technical challenges faced in HEVs and PHEVs. Power electronics and electric machines used in a vehicle have been considered significantly challenging. It is disturbing to environmental conditions such as extremely high and low temperatures, vibration, shock, and transient behavior affecting electric motors … Continue reading What were the key technological challenges in HEVs and PHEVs?

The main manufacturers like Toyota, Ford, Honda, and even Nissan didn’t delay the launching of HEVs in the US. It is not surprising, but the US was way ahead of any other countries across the world. The models launched in the US under different manufacturers in Toyota in 2011 are:- Prius, Camry, and Highlander. In Ford in 2011 are:- Fusion, Escape, Mariner and Milan, In … Continue reading Which HEVs captured the headline in the USA in 2011?
