Harley-Davidson LiveWire introduces new all-electric powertrain
The Harley-Davidson LiveWire is an all-new, all-electric motorcycle designed to offer the rider a high-performance motorcycling experience infused with a new level of technology, and the premium look and feel of a Harley-Davidson product.
Propelled by the immediate torque of the H-D Revelation all-electric powertrain, the LiveWire motorcycle is capable of rapid acceleration with just a twist of the throttle—no clutching or gear shifting is required. With up to 146 miles (235 km) of range, performance is optimized for the urban street-rider.
The instant torque provided by the H-D Revelation powertrain delivers rapid acceleration from a stop; the LiveWire motorcycle can go from 0 to 60 mph (0 to 100 kph) in 3.0 seconds and 60 to 80 mph (100 to 129 kph) in 1.9 seconds.
Because electric power requires no clutch and no gear shifting, operation for new riders is greatly simplified. Riders will also appreciate the braking effect of the power regeneration mode as it adds charge to the battery, especially in urban traffic that often requires a lot of slow-rolling and stop-and-go riding.
The LiveWire motorcycle is powered by the all-new H-D Revelation permanent-magnet electric motor rated at 105 hp (78 kW) and producing 86 ft·lb of torque. Unlike an internal combustion engine (ICE), the H-D Revelation can produce 100% of its rated torque the instant the throttle is twisted, and 100% of that torque is always available, resulting in seamless acceleration for an exhilarating ride. The LiveWire can accelerate from 0-60 mph in 3.0 seconds, and 60-80 mph in 1.9 seconds.
The H-D Revelation motor is cooled by a water jacket, with coolant circulated through a small radiator, and is positioned longitudinally and low in the chassis to lower the motorcycle’s center of gravity, and aid maneuverability.
The H-D Revelation electric powertrain produces minimal vibration, very little heat, and minimal noise, all of which enhance rider comfort. When the rider activates the LiveWire motorcycle powertrain, the electric motor will produce a subtle pulsing of torque, a heartbeat sensation designed to let the rider know the bike has come to life and is ready to ride. The pulsing ceases when the motorcycle begins to move, and resumes when the motorcycle comes to a stop. The LiveWire model is designed to produce a mechanical signature Harley-Davidson sound as it accelerates and gains speed—a new sound that represents the smooth, electric power of the motorcycle.
The LiveWire motorcycle is aimed at greater convenience for owners because many of the routine maintenance items required of a motorcycle powered by an internal combustion engine are eliminated: there is no engine oil to change, and no spark plugs, air filter, or primary drive to service. Electric power also eliminates maintenance issues associated with ethanol-blend gasoline and off-season storage.
The LiveWire motorcycle is powered by a 15.5 kWh high-voltage battery (or RESS; rechargeable energy storage system) composed of lithium-ion cells, positioned in the center of the motorcycle and surrounded by the motorcycle’s cast-aluminum frame. The RESS is enclosed in a cast-aluminum housing, which also acts as a heat-sink to help cool the cells. The sides of the RESS housing are finned and exposed to the air and are visible within the motorcycle frame. Small air scoops on the motorcycle bodywork duct cooling air to the upper portion of the RESS housing. The RESS housing is attached to the frame at several points and contributes to the over-all rigidity of the chassis. The motorcycle is also equipped with a 12-volt lithium-ion accessory battery that provides power for startup and key fob recognition.
The battery provides 146 miles (235 km) of city range or 95 miles (152 km) of combined stop-and-go and highway range as measured using the MIC City and MIC Combined tests and 98 miles (158 km) using World Motorcycle Test Cycle (WMTC). DC fast charge (DCFC) technology provides a 0-80% of battery charge in 40 minutes or 0-100% charge in 60 minutes. The high-voltage battery has a 5-year, unlimited-mileage warranty.
Power regeneration is accomplished through the drivetrain when the LiveWire motorcycle is coasting “off-throttle,” as the motor becomes a generator putting charge back into the RESS. The rider will feel the regeneration process as an engine-braking effect. The level of regeneration is programmed as an element of each of the four Ride Modes, and the regeneration setting can also be adjusted by the rider as an element of multiple custom Ride Modes.
The LiveWire motorcycle is equipped with an onboard Level 1 charger that plugs into a standard 120-volt (or 240-volt) household outlet with a special power cord that stores below the motorcycle seat. Level 1 RPH (range per hour) of charging time is 13 miles for each hour of charging; and the LiveWire motorcycle will get a full charge overnight with Level 1 charging.
DC fast charge (DCFC) technology is standard on the LiveWire, and may be used to charge the motorcycle through a SAE J1772 connector (or CCS2 – IEC type 2 charging connector in European and some other international markets). DC fast charge RPH (range per hour) of charging time is 192 miles for each hour of charging.
The LiveWire motorcycle may be charged with a Level 2 charging station, but it will charge at the Level 1 rate. The charging port is located below a cap in the bodywork forward of the motorcycle seat. All participating authorized Harley-Davidson dealers selling the LiveWire model will offer a DCFC charging station at their dealership.
U.S. LiveWire customers will receive free charging on ChargePoint stations at participating LiveWire dealers for the first two years. Additionally, Harley-Davidson will provide U.S. LiveWire owners with 500 kWh of free charging service at Electrify America DCFC charging stations.
The LiveWire model is the first in a broad portfolio of electric two-wheelers from Harley-Davidson. It will be available in 2019 through select authorized Harley-Davidson dealerships in the U.S., Canada, and most European countries where Harley-Davidson conducts business, with expanding global availability planned for 2020 through 2021.
