Technology
The origins of our technology are in the computer hard disk drive industry, which advanced the state of the art in high power density and high efficiency motors and actuators. High Tide turned these technologies toward high-energy BLDC (brushless DC) miniature generators, initially for the military.
Our electromagnetic designs use techniques we pioneered in 3D non-linear FEA (finite element analysis). Unique topologies are seeded and then improved numerically. The materials used are the highest energy NdBFe magnets coupled with low-loss steel laminations. Our designs are covered by numerous patents issued and pending.
Shown in the animation are the magnetic flux density variations as the generator spins. The oscillating fields generate the coil currents that charge the batteries (Faraday’s Law). Steel saturation and magnet recoil curves are fully simulated. By varying the detailed dimensions and topology, smoothness, compactness, high efficiency and high power output are obtained.
MechanicsWe employ best practices in mechanics design, including 3D structural FEA in areas of concern. Static & dynamic stress and deflections are modeled. Shown is a typical mesh for our RollerGen assembly.
Digital microprocessor power control and analog switchers gather the electrical power produced by the pedal-driven generator, and tailor it to the unique needs of the devices under charge (BatteryBOS) and the comfort of the user. The controller allows the user to take ergonomic control of the charging experience by modifying the resistance of the pedals.
Finally, the electrical power is stored in High Tide's BatteryBOS portable power pack. Our BatteryBOS utilizes latest generation Li-ion chemistries to store the energy as quickly as it is generated.
