Innovation at Hyundai: Technology Inside Hyundai’s Ecofriendly cars

Hyundai is one of the leading automakers of the world. In the recent years, while the demand for ecofriendly cars has increased, several automakers have released hybrid and fully electric versions to match customer demand. Hyundai is an innovative brand and aspires to become a leader in ecofriendly vehicle segment. By 2020 it aspires to establish a full lineup of ecofriendly vehicles. Till now it has released 22 such cars of which 12 are hybrid electric vehicles, 6 are plugin hybrid electric vehicles, 2 are electric vehicles and remaining 2 hydrogen fuel cell electric vehicles. The focus of its Blue Drive strategy is to improve the functionality of automobiles while also reducing emissions and fuel consumption. Research and development at Hyundai continues to focus upon passenger safety and lowering carbon footprint. Here are some of the leading ecofriendly models made by Hyundai and the technologies inside them.

NEXO:

Technologically-advanced 2019 NEXO fuel cell SUV is powered by Hydrogen energy and produces zero emissions. The hydrogen fuel cell engine of Nexo generates electricity by mixing oxygen with compressed hydrogen to create a flow of electrons. It’s the only mass-produced fuel cell SUV for the U.S. market boasting an estimated range of 380 miles. For driver safety and convenience, Nexo includes several features like Forward Collision-Avoidance Assist (FCA), Lane Following Assist (LFA), Driver Attention Warning (DAW), High Beam Assist (HBA) and Remote Smart Parking Assist (RSPA). Moreover, the car can be refuelled in as little as 5 minutes. Its three separate hydrogen tanks are there in the rear. With 161 peak horsepower (120 kW) and 291 lb.-ft. of torque, acceleration and power as well as overall performance of NEXO is better compared to Tucson fuel cell. Nexo Blue comes for a starting MSRP of $58,300 and Nexo limited for a starting MSRP of $61,800 in U.S. Nexo Blue has a range of 380 miles whereas Nexo limited that of 354 miles.

ix35 fuel cell:

ix35 is a third generation fuel cell electric vehicle (FCEV) by Hyundai. The company started the production of its ix35 fuel cell at its Ulsan manufacturing plant in January 2013. Hyundai became the first carmaker to start the commercial production of a hydrogen powered vehicle and first complete car rolled off the assembly line in Feb 2013. ix35 won the prestigious FuturAuto accolade for being he first commercially mass produced hydrogen powered vehicle. It is a third generation FCEV (fuel cell electric vehicle) from Hyundai. Tucson FCEV, introduced in 2005 was the first one to be powered by Hyundai’s first 80 kW (109 ps) fuel cell. ix35 comes loaded with a a 100 kW (136 ps) electric motor which allows it to achieve a max speed of 160 km/h. Equipped with two hydrogen storage tanks having a total capacity of 5.64Kg, the vehicle can travel 594 kms on a single charge. The vehicle can start reliably even in very low temperatures like minus 20 degree celsius.

A 24 kWh lithium ­ion polymer battery, which Hyundai has jointly developed with LG Chemical stores the energy. the fuel cells turn hydrogen’s chemical energy into electromechanical energy. A polymer electrolyte membrane lies sandwiched between the anode and cathode inside the fuel cell. Electric current is created in three stages:

• When hydrogen gas flows the over the anode, it gets split into hydrogen ions (protons and electrons).
• Only protons can pass through the polymer electrolyte membrane. Electrons travel to an external circuit operating the motor.
• Electrons and protons react with oxygen at the cathode generating H20 which is the only waste product to be emitted from the tail pipes.

Powertrain and transmission:

• Front-mounted induction motor with two mid-mounted hydrogen fuel cell storage tanks.
• Battery – 24 kWh lithium polymer 
• Fuel cell – 100 kW fuel cell with two hydrogen storage tanks
• Power / torque – 100 kW (136 ps) / 300 Nm available from zero rpm
• Transmission – Gear differential unit
• Emissions – H₂O (water) only

Kona electric:

Sonata Hybrid:

2018 Sonata Hybrid’s heart is alive with a 2.0-liter Nu GDI four-cylinder engine coupled with a six-speed automatic transmission housing a powerful 38 kW electric motor and clutch where the torque converter is found. Its Transmission-Mounted Electrical Device (TMED) delivers the same responsive, engaging driving features that Sonata riders expect. However, fuel economy is improved due to a larger electric motor.

The innovative transmission with an electric oil pump offers higher efficiency. Sonata Hybrid can run solely on electric power at speeds up to 75 mph with the gasoline engine decoupled from the rest of the drivetrain.

The Nu engine inside Sonata Hybrid produces 154 horsepower and 140 lb. ft. of torque. Its electric motor produces 38 kW (51 horsepower) and 151 lb. ft. of torque. Hybrid system net power is 193 horsepower at 6,000 rpm. Sonata Hybrid SE has preliminary internal estimates of 39 mpg in the city, 45 mpg on the highway and 42 mpg combined. Total range of Sonata Hybrid is estimated at above 650 miles under typical driving conditions.

The lithium-ion polymer battery pack has capacity of 1.76 kWh. The battery pack fits under the trunk floor, allowing for a flat trunk floor as well as available 60/40 split-folding rear seats. Sonata Hybrid offers 13.3 cu. ft. of cargo volume, owing to to the compact battery pack dimensions and efficient design of the vehicle. Cargo volume is improved by placing the battery pack under the trunk floor. The total interior volume becomes 106.1 cu. ft., the highest in the segment.

Sonata plugin hybrid:

Although Sonata Plug-in Hybrid is technologically much advanced, its drive feels similar to the Sonata Hybrid. However, there is the additional benefit of extended all-electric range. A 9.8 kWh lithium-ion polymer battery pack, which is more than five times larger than the one inside Sonata Hybrid, gives Sonata Plug-in Hybrid an EPA-estimated all-electric range of up to 27 miles. A level-two charger can recharge the vehicle in less than three hours. The power delivery of a hybrid gasoline engine is perfect for long trips with the additional benefit of environment- friendly all-electric range for commuting. Most drivers can commute daily without using a single drop of fuel. Total estimated range is an impressive 590 miles.

The Sonata Plug-in Hybrid has a six-speed automatic transmission with Hyundai’s Transmission-Mounted Electrical Device (TMED), a 50 kW electric motor, instead of a torque converter. The 50 kW electric motor is 32% more powerful than the one Sonata Hybrid has. It allows EV operation at higher engine load and speed. Due to the 2.0-liter Nu four-cylinder GDI engine coupled with the electric motor, Sonata Plug-in Hybrid can operate just like Sonata Hybrid once the onboard battery charge is depleted. Sonata Plug-in Nu engine produces 154 horsepower and 140 lb. ft. of torque. Total system output is 202 horsepower at 6,000 rpm.
