Electric Range and Efficiency

As a fully electric vehicle, the i-MiEV does not have a traditional fuel tank or use gasoline. Instead, it relies on a lithium-ion battery pack to power its electric motor. Let’s examine the key metrics related to the i-MiEV’s electric range and efficiency:

Battery Capacity

The Mitsubishi i-MiEV is equipped with a 16 kWh lithium-ion battery pack. This battery serves as the vehicle’s “fuel tank,” storing the electrical energy used to power the car.

EPA-Rated Range

According to the U.S. Environmental Protection Agency (EPA), the 2012 Mitsubishi i-MiEV has an official range of 62 miles (100 km) on a full charge. This rating is based on the EPA’s standardized testing procedures, which aim to reflect real-world driving conditions.

Efficiency (MPGe)

The EPA rates the 2012 i-MiEV’s efficiency as follows:

• City: 126 MPGe
• Highway: 99 MPGe
• Combined: 112 MPGe

MPGe stands for “Miles Per Gallon equivalent” and is used to compare the energy efficiency of electric vehicles to traditional gasoline-powered cars.

Range per kWh

To calculate the i-MiEV’s range per kilowatt-hour of battery capacity, we can divide the EPA-rated range by the battery capacity:

62 miles / 16 kWh = 3.875 miles per kWh

This means the i-MiEV can travel approximately 3.875 miles for every kilowatt-hour of energy stored in its battery.

Real-World Range Variations

It’s important to note that real-world range can vary significantly based on factors like driving conditions, weather, and individual driving habits. According to the EV Database, the i-MiEV’s practical range may vary as follows:

These figures highlight how weather conditions and driving environments can impact the i-MiEV’s range.

Efficiency Across Variants and Generations

The Mitsubishi i-MiEV has seen some changes and improvements over its production run. Let’s explore how efficiency has evolved across different variants and generations:

Original Japanese Model (2009-2011)

The initial i-MiEV model launched in Japan had a slightly different battery configuration:

• Battery Capacity: 16 kWh
• Range: 160 km (99 miles) on the Japanese JC08 test cycle

It’s important to note that the Japanese test cycle tends to produce more optimistic range estimates compared to the EPA cycle used in the United States.

North American Model (2012-2017)

When the i-MiEV was introduced to the North American market, it underwent some changes to meet local regulations and preferences:

• Battery Capacity: 16 kWh (unchanged)
• EPA Range: 62 miles (100 km)
• Efficiency: 112 MPGe combined

The North American model also featured a slightly longer body to meet U.S. crash safety standards, which may have impacted its efficiency slightly.

European Variants: Peugeot iOn and Citroën C-Zero

In Europe, rebadged versions of the i-MiEV were sold as the Peugeot iOn and Citroën C-Zero. These models had similar specifications to the i-MiEV but may have had slight differences in range and efficiency ratings due to different testing standards in Europe.

2013 Model Year Update

In 2013, Mitsubishi made some updates to the i-MiEV’s battery technology:

• New LEV50N battery cells replaced the previous LEV50 cells
• The number of cells remained the same at 88
• Overall battery capacity was unchanged at 16 kWh
• Improvements in regenerative braking efficiency helped maintain range despite changes in cell technology

Charging and Energy Consumption

Understanding the i-MiEV’s charging capabilities and energy consumption is crucial for potential owners. Let’s delve into these aspects:

Charging Options

The Mitsubishi i-MiEV offers several charging options:

1. Level 1 Charging (120V): Using a standard household outlet, the i-MiEV can be fully charged in about 22 hours.

2. Level 2 Charging (240V): With a 240V outlet or dedicated EV charger, charging time is reduced to approximately 7 hours for a full charge.

3. DC Fast Charging (CHAdeMO): The i-MiEV is equipped with a CHAdeMO port for fast charging, allowing it to reach 80% charge in about 30 minutes.

Energy Consumption

The EV Database provides detailed energy consumption estimates for the i-MiEV under various conditions:

These figures illustrate how energy consumption can vary significantly based on driving conditions and weather.
