A “City” range test is specified to determine riding range during “stop-and-go” operation typically found in urban areas. This estimate is provided following the SAE J2982 Riding Range Test Procedure for On-Highway Electric Motorcycles to provide a reasonable and consistent basis for manufacturers to inform prospective owners of the riding range that can be expected under specified operating conditions. Actual range will vary based upon riding conditions and habits.

This is meant to provide a range value that riders can expect to achieve when riding their motorcycle on a highway at a steady speed of 89 km/h according to the SAE J2982 Riding Range Test Procedure. Actual range will vary based upon riding conditions and habits.

The combined or “Highway Commuting” range calculation procedure is specified to determine riding range in urban areas when operation consists of 50% stop-and-go operation and 50% operation on urban freeways under levels of congestion that allow for quasi-steady speeds of 89 km/h. This estimate is provided following the SAE J2982 Riding Range Test Procedure. Actual range will vary based upon riding conditions and habits.

This is meant to provide a range value that riders can expect to achieve when riding their motorcycle on a highway at a steady speed of 113 km/h according to the SAE J2982 Riding Range Test Procedure. Actual range will vary based upon riding conditions and habits.

This represents the expected life of the power pack, to 80% of its original capacity, when the motorcycle is ridden according to the EPA's "city" UDDS duty cycle. An electric motorcycle can continue to function perfectly normal with a power pack that has lost over 20% of its original capacity. The only certain change will be a reduction in maximum range.

The Formula:
Estimated pack life (miles / km) = (EPA UDDS range) * (cycle-life rating of the battery) * (90%, to account for 20% linear capacity loss over this rated life)

Maximum capacity tends to be the electric vehicle industry’s choice for reporting the maximum amount of energy that can be stored in a vehicle’s power pack.

About kWh : Where gasoline vehicles use gallons, electric vehicles frequently use kilowatt hours (kWh) to measure the total possible ‘fuel’ or energy storage capacity.

The Formula:
Maximum kWh = (# of cells) * (cell Amp-hour capacity rating) * (cell max voltage rating)

Nominal capacity is the most accurate measure of the amount of usable energy that can be stored in a vehicle’s power pack. It differs from maximum capacity because it is calculated using an average voltage that is more often ‘the norm’ rather than a maximum which is rarely seen.

Nominal kWh = (# of cells) * (cell Amp-hour capacity rating) * (cell nominal voltage rating)

Typical charge time using the motorcycle's on-board charger and a standard 110 V or 220 V outlet.

Note that charge times to 95% are referenced for two reasons. First, with normal use, it’s rare that a power pack would be discharged to 0%. Second, "topping off" from 95% to 100% takes 30 minutes, regardless of charging method, in order to maximize battery capacity.

The Charge Tank is an optional dealer installed 2.5 kW accessory that nearly triples the onboard charging speed when used with level 2 charging stations. It is compatible only with select Zero motorcycles model year 2015 and later. It is not compatible with motorcycles equipped with the Power Tank accessory.

Zero's scalable charging accessories allow customers to add multiple standalone chargers (in addition to the existing on-board unit) for up to a ~75% reduction in charge time, depending on the model and year.

Zero Motorcycles generally recommends that only one charger be plugged into one circuit, including the motorcycle's on-board charger. Plugging multiple chargers into a single circuit risks drawing too much power, thereby activating the source's circuit breaker.

Some household circuits—including many in Europe—operate at high enough capacities to power multiple chargers. It is the customer's responsibility to first verify that any given power source is rated at high enough output to safely support the load of a charger or chargers.

Zero motorcycles' on-board chargers draw up to 1500W (Zero SP, DSP) or 800W (Zero FXP). Off-board accessory chargers draw up to 1200W.

Zero's scalable charging accessory allow customers to add multiple standalone chargers (in addition to the existing on-board unit) for up to a ~75% reduction in charge time, depending on the model and year.

For 2015 motorcycles, the max number of accessory chargers is:
Zero SP and Zero DSP = 4
Zero FXP 5.7 = 3
Zero FXP 2.8 = 1

Please keep in mind that most household electricity circuits are rated to 230V/16A, which can only support two chargers. As a result, in order to make use of Zero's quick-charge accessories, you must plug additional chargers into a separate 230V/16A circuit. If connecting to any other, higher-rated household circuit, first ensure that it can safely support the load of each of Zero's 1.300W input chargers.
