Electric Vehicle Glossary -What is What

These terms are commonly used in discussions about electric vehicles and can help consumers better understand the technology and terminology associated with this rapidly evolving industry.

What is what in area of electric vehicle

Battery Capacity: The amount of electrical energy that can be stored in a battery, usually measured in kilowatt-hours (kWh). Battery capacity affects the range and performance of an electric vehicle.

The battery capacity directly influences the range of the EV, as a higher capacity battery can store more energy, allowing the vehicle to travel farther on a single charge. Battery capacity is a crucial consideration for EV buyers, as it determines the vehicle's practical usability and suitability for their driving needs.

EV manufacturers often advertise the battery capacity of their vehicles as a key feature, providing consumers with information to compare different models and understand how far they can expect to travel on a single charge.

Battery Electric Vehicle (BEV): A type of electric vehicle that runs entirely on electric power stored in rechargeable batteries. BEVs do not have an internal combustion engine.

Charging Station: A location where electric vehicles can be recharged by connecting them to an electrical power source. Charging stations come in various types, including home chargers, public chargers, and fast chargers.

Cycle life : Cycle life, in the context of electric vehicles (EVs), refers to the number of charge-discharge cycles that a battery can undergo before its performance degrades significantly. It is an essential metric for evaluating the durability and longevity of EV batteries.

The cycle life of a battery is influenced by various factors, including its chemistry, design, operating conditions, and maintenance. Generally, EV manufacturers provide cycle life estimates based on standardized testing protocols and real-world usage scenarios.

A longer cycle life indicates that the battery can sustain more charge-discharge cycles over its lifetime, resulting in extended longevity and reduced need for replacement. Battery management systems and proper charging practices can also impact cycle life by optimizing charging and discharging processes to minimize degradation.

EV buyers often consider cycle life when evaluating battery durability and total cost of ownership, as batteries with longer cycle life typically offer better value and reliability over the vehicle's lifespan.

Depth of Discharge (DoD):The degree to which a battery is discharged in each cycle can have a notable impact on its longevity. Batteries that undergo regular deep discharges, where a significant portion of their capacity is depleted (e.g., 10-20% remaining), may experience heightened stress levels, potentially resulting in a diminished cycle life.

Driving mode : Driving modes in electric vehicles (EVs) offer drivers a range of options to tailor their driving experience to their preferences and driving conditions. Common driving modes include **Economy Mode (E)**, **Controlled Efficiency (C)**, **Sport**, **Normal**, and **Comfort**. 

Electric Motor: The component of an electric vehicle that converts electrical energy from the battery into mechanical energy to drive the vehicle's wheels. Electric motors are more efficient than internal combustion engines and produce instant torque.

Electric Vehicle: A general term for any vehicle that runs partially or entirely on electricity. This includes BEVs, plug-in hybrid electric vehicles (PHEVs), and hybrid electric vehicles (HEVs).

Electric Vehicle Supply Equipment (EVSE): The infrastructure needed to charge electric vehicles, including charging stations, connectors, and related hardware.

Hybrid Electric Vehicle (HEV): A vehicle that combines an internal combustion engine with an electric propulsion system. HEVs use both gasoline and electricity for propulsion but cannot be plugged in to recharge the battery.

Kilo Watt (KV)-  One kilowatt (kW) corresponds to 1,000 watts. In electric vehicles (EVs), the power output of their electric motors is commonly expressed in kilowatts. This measurement signifies the motor's capacity to convert electrical energy into mechanical force, propelling the vehicle forward. A higher kW rating usually indicates that the motor can generate greater power, leading to improved acceleration and overall performance.

Plug-in Hybrid Electric Vehicle (PHEV): A hybrid vehicle that combines an internal combustion engine with a rechargeable battery. PHEVs can be charged from an external power source and can also operate using gasoline.

Range- In the context of electric vehicles (EVs), "range" refers to the distance the vehicle can travel on a single charge of its battery pack before needing to be recharged. It is a crucial metric for EVs, as it determines the practical usability and convenience of the vehicle for everyday use. Range is influenced by various factors, including battery capacity, efficiency, driving conditions, terrain, and driving habits. Manufacturers often provide estimated range figures based on standardized testing procedures to help consumers understand how far a particular EV can travel under typical driving conditions.

Range Anxiety: The fear or concern that an electric vehicle may run out of battery charge before reaching its destination or a charging station. Range anxiety is often cited as a barrier to the widespread adoption of electric vehicles.

Regenerative Braking : A technology used in electric and hybrid vehicles where the kinetic energy produced during braking is captured and converted into electricity, which is then stored in the vehicle's battery.
