Sanyo Electric has released the ground when riding through the recovery of the electricity generated by the motor for the lithium-ion rechargeable battery,Sony for electric bicycle (Figure 1). According to this model, called “energy-saving charge mode” and the auxiliary power larger “power mode (Power Mode)” compared to extend the driving range of approximately 53% (Figure 2). The car with 26-inch “CY-SPL226″ and 24-inch “CY-SPL224″ two, prices are ¥ 157,290. Will be held April 21, 2010 on sale.
Of the original model can be recovered during braking or downhill power. However, Teng Chiao pedal on the ground when the charging function is not available. This time the newly developed energy-saving charging mode, even in the plains on the road can also be charged (Figure 3). Under normal circumstances, driving in the plains state of charging, the pedal is more heavy, so the rider will increase the burden,VGP-BPS2，VGP-BPS2A, but the new car “in order to minimize the impact on the feeling of driving, will monitor the driving status, and to ms for the to determine the timing recovery unit “(consumer electronics company Sanyo Electric Appliance Division, including the Ministry of Planning and Manpower Planning, Minister of two-wheelers of goods Tetsuya Taniguchi).
Charge condition is to prevent the shaking in 5 seconds after the start, but also to achieve the speed of 7km / h or more. Of course, even in energy-saving charge mode, if the start uphill and speed up the auxiliary power is required, the same can be automatically switched to motor-assisted drive mode. Traveling time and help regeneration switching, VGP-BPL2，VGP-BPL2C,can embed crank torque sensor to detect the pedal pedal power, the use of motor speed calculated by the speed and acceleration through the speed calculated to determine and control (Figure 4). For example, the hard phases of acceleration will not carry out electrical regeneration. “As hard phases of acceleration when the acceleration will be increased, this time in order to avoid electrical regeneration, would limit the recovery of power following an acceleration carry out the” (consumer electronics company Sanyo Electric Appliance Division, Department of Manufacturing Technology 2 omnibus Minister of dry self-denial) .
In addition to saving outside the charge mode, this new additional features include battery power is left to inform the rider with less “Electricity Storage (Power Reserve)” function (Figure 4). Battery remaining capacity is about 1Ah, they will stop using the auxiliary power provided by the motor driving mode. If, after a long press the power button, can use the remaining 1Ah capacity. According to reports, in energy-saving charge mode, it can be riding around 6km. In addition, lithium-ion rechargeable battery with a rated capacity of 7.6Ah.VGP-BPS8，VGP-BPS8A,VGP-BPL8, VGP-BPL8A.
