Power Recharge Generator system for E Bikes -- 2

Component’s

3 main battery ( Bat1, Bat2, Bat3) input connections using XT-90 Connectors.

3 (35 amp) Resettable Fuses with Hi Current (40 amp) Diodes Epoxied to them for Inverse Battery protection.

3 (40 amp DC-DC) SSR relays (see attached spec sheet).

2 - DPDT switches for Battery selection.

3 - Dc to DC converters mounted on proto board.

Buss Bars and Wiring.

Operation:

Power from battery source (54v via 3 batteries)

All Non Battery (hi current) wiring is Red, White, and Blue for battery operation 1, 2, 3. (color coded traceable)

Each Battery Positive connected to Resettable Fuse with Inverse Diode epoxied to fuse with its output wired to + Load side of SSR

The – Load side is connected to the motor power bus bar with motor controller power cables attached.

All battery Negative, Motor controllers, and DC-DC Converter inputs are common GND.

Battery switches (normally open) are wired (non-common leg) to + Load of SSR with switch output (common leg) to DC-DC converter + input power.

The DC-DC converters + and - outputs are connected to their respective SSR. DC-DC converters have isolated inputs and outputs to prevent crossover.

SSR relays will only power on when selected switch is set for battery power (1,2,3)

Issues:

Current switch is DPDT (ok for 2 battery operation). For 3 or more battery switching, a gang or rotary switch that only allows one position active at a time. (currently 2 batteries can be simultaneously engaged on the dual switch system)

SSR DC to DC uses an SCR and when any SSR is switched on it allows leakage on the motor buss bar to the other SSR’s.

Leakage does help in allowing motor controllers to actually have power available during battery switching. Controllers have a hi farad cap internally to buffer incoming power and for short period of storage

This is exactly what would work with the bikes or any rotating disc with magnets passing by a coil (with stark converter-regulator). It looks a match to application.

The coil or coils would be mounted into or onto the brake caliper (redesigned caliper) for example as shown. The coil & converter could be built into or attached to the caliper (have to determine size and qty). The output is controlled by the regulator diode and can be configured to provide the voltage required to charge the battery but the current output is questionable. The converters and coils can also be daisy changed in series (12v+12v+12v etc.) to generate a range of voltages. As to the power output – That would depend on the coil size with respect to magnets (number, strength and size) and would require testing. The magnets must be mounted in a non-ferrous disc. The construction of the disc can be accomplished a few ways to accommodate the isolation. The isolation is necessary to allow only the magnet to pass by the coil. The main part of the disc can be made from Aluminum for the magnets and the outermost ring of steel for the brake pads (this allows for a symmetrical continuous output by the coils

Another generating method is using a coil with a standard magnetic bar moving in and out of the coil. This could be achieved by integrating a coil around the shock absorber (or fork tube, anything that moves in and out and is not ferrous) and the core rod of the shock (magnetic preferably) to generate energy as the rod moves in and out. Then adding
