BAGNOLET, France (April 19) – WaveCrest recently launched its first electric bike, featuring a breakthrough electric propulsion technology that transforms electrical energy into mechanical motion – and vice versa – with exceptional power and efficiency. The electric bikes’ power comes from Saft’s nickel-metal hydride (Ni-MH) batteries. In the rear hub is its patented WaveCrest Adaptive Motor system, and in the front hub are the Saft Ni-MH batteries composed of Saft’s VH D cells. By close consultation with WaveCrest, Saft engineers have helped ensure the best electronic interfaces for what it is a unique circular battery. Thirty Ni-MH cells are linked via 15 cables and 4 connector systems to the bike’s motor and controls. The TidalForce M-750 has a range of 20 miles (about 32 km) on a single battery charge. It reaches top speeds of 20 mph, which is consistent with U.S government regulation of light transport vehicles.
In addition to the electric adaptive motor system, the technology features customizable controls that manage the system’s total performance – and an advanced Saft battery system that delivers excellent power, range and efficiency. Thousands of times a second, optical sensors in the motor inform a digital signal processor how fast the motor is rotating and how much torque it is generating. The chip then uses algorithms to optimize motor efficiency at that speed and at that torque, automatically recharging the battery when feasible. More info @: www.saftbatteries.com
