THE MOTOR
Rayvolt hubs are a complex brushless 3 phase dc motor comprising 48 different copper coils and magnets that are placed on the outermost perimeter of the motor for the best possible torque. The controller receives heat and position data from the coils and within one millisecond computes where to put the next load. Such accuracy produces a Pure Sine Wave (PSW) current, offering unmatched ride comfort:
- More Acceleration
- More Response
- More Torque
- Less Noise
- Less Vibration
- Less Consumption
BATTERIES
At the core of any electric vehicle, its performance and life expectancy are directly linked to the type of cell used.The capacity of the battery pack* also depends on the number of cells used. Rayvolt uses 13 cells in a series to reach a nominal voltage of 48V. At peak voltage, a full charge of 54.6V gives incredible power. We use a minimum of 4 cells in parallel (52 cells in total) or 8 cells in parallel (104 Cells in total). This gives an unmatched capacity of 550Wh and 1100Wh – most of the industry uses 300 to 360Wh.
Battery quality is linked to how the cells are packed and used. Using a state-of-the-art battery management system in our packs, each cell is connected to it before delivering the charge. This high-tech design balances the charge between each cell and can cut the connection in case of a short circuit. This ensures the best possible performance while making the battery safer.
INTELLIGENT REGENERATIVE BREAK SYSTEM
We created an electronic braking system, fitted into the brake levers, that sends a data signal to the motor controller that provokes a reverse effect in the motor. This converts torque into resistance using the wheel inertia to generate electricity and recharge the batteries.
In simple words, the regenerative braking acts like an ultra powerful dynamo when the levers are pulled.
The intelligent iRBS is linked to EIVA’s built-in gyroscope allowing the bike to detect the cycling environment. It then provides the necessary amount of regenerative brake according to the angle of the hill.
INTELLIGENT PEDAL ASSIST
Dual Sensor Crank Set
The Electronic Crank comes fitted with a Load Cell, which measures both the Torque applied to the pedal and the crank rotary speed.
A Controller then computes these two values, and with a smart algorithm, provides perfectly smooth power based on muscle activity.
REGENERATIVE BACK-PEDALING BRAKES
While rotating the pedals backward, a pedal sensor sends a data signal to the controller, which provokes a reverse effect in the motor. Similar to a classic coaster brake with the extra benefits of battery recharge and a custom adjustable brake curve based on the back-pedaling speed.
EIVA 2.0
The EIVA is Rayvolt’s custom designed software which is used to control, customize, and monitor your bike.The EIVA computer can be mounted to the handlebars and is ready to go when you are.
The app can be downloaded for use on an existing smartphone.
