Is the electromagnetic radiation emitted by an EV worrying?

It is absolutely safe to drive an EV. Even though it is true that its powertrain parts (motor, battery pack, and wiring) generate higher electromagnetic radiation as opposed to the internal combustion engine. But this level of electromagnetic radiation is negligible and not destructive. 

According to SINTEF (a Norwegian research group), the radiation percentage emitted by an EV is below the recommended limits introduced by the International Commission on Non-Ionizing Radiation Protection. 

Can I tow with an EV?

This is not recommended because when an EV is made, towing isn’t kept in mind. Different EVs in the market do not show any tow ratings and even the ones who can tow, can’t tow big loads. This is because EVs are aerodynamically slippery and they are not built to tow. 

Are plug-in hybrids better?

Since there are many ways to blend electric motors and gas engines together in one powertrain, it is difficult to categorize plug-in hybrids. If you want to find out whether a specific plug-in hybrid EV is worthy, ask yourself whether it offers a helpful electric range and a strong motor to use that range without exploiting the combustion engine? 

This is important because an ideal plug-in hybrid EV usage situation is routine electric driving blended with long-distance gas usefulness. A PHEV should be equipped with an electric motor that generates above 100 horses and offers at least 20 miles of range.

What happens when an EV has a low battery?

When an EV starts to get a low battery, it will immediately decrease the available power and notify the driver to reach a charging station or stop the car. 

What are the common terms and acronyms related to EVs?

BEV: Battery-electric vehicle

CCS: Combined Charging System. This is the DC fast charging connector utilized by most manufacturers.

CHAdeMO: CHArge de MOve is a unique DC fast charging connector. The EVs in the industry equipped with this connector is Mitsubishi Outlander PHEV and Nissan Leaf. 

Charger: This is the hardware responsible for transforming AC to DC in order to charge the battery. 

EVSE: Electric-vehicle supply equipment. This is the industry term for a charger. It adds public charging stations and other tools needed to link the EV to an electricity source.

ICE: Internal Combustion Engine. It refers to when an ICE is parked where EV is supposed to be charged and stops the EV driver from plugging in. 

J1772: This is the SAE standard for EV charging. Plus, it’s the connector all EVs other than Tesla utilize for Level 1 and 2 charging. 

kW: This is equal to 1000 watts and this unit refers to EV charging and the power output of an EV. 

kWh: Kilowatt-hour. This is a unit of energy that’s equivalent to 1 kilowatt which is sustained for an hour. 

Level 1: This is 120-volt AC charging having a power output of 1 kilowatt. Level 1 charging gives a maximum of 5 miles range. 

Level 2: This is 240-volt AC charging that’s seen in shopping malls, offices, and homes. Level 2 charging offers 6-19 kW and can charge an EV overnight. 

Level 3: This charging connection offers DC and high power. It fuels the battery pack directly. Its usual power output ranges from 50-350 kW. With this power, an EV can drive for 100 miles.

MPGe: Miles per gallon of gasoline-equivalent. This is an estimate for efficiency for PHEVs, EVs, and hydrogen cars which can be compared with a gas car’s mpg. 

Regenerative braking: This refers to utilizing the electric motors to slow down the car by turning kinetic energy into electricity, that’s kept in the battery pack.

SOC: State of charge. This is a level of energy presently available in the battery pack. It’s displayed as a percentage of the usable capacity.
