How Voltraware is Powering Micromobility Solutions Using AirFuel Resonant<\/span><\/h1>\n

<\/span><\/p>\n

Established in 2019, Voltraware<\/span><\/span><\/a> is a fabless semiconductor company specializing in the research and development of integrated circuits for wireless power transfer applications. Their technology is based on <\/span>magnetic resonance<\/span><\/a><\/span>, meaning it can charge multiple devices at a distance without the need for a precise alignment between the transmitter and receiver.<\/span><\/p>\n

Products that use Voltraware\u2019s semiconductor chips for wireless charging are automatic, reliable, and safe. The wireless power receiver automatically starts charging the battery when it enters the transmitter\u2019s charging zone. Thanks to <\/span>AirFuel Resonant<\/span><\/span><\/a>\u2122 wireless charging technology, eBikes and eScooters that use Voltraware\u2019s chips for wireless charging can simply \u201cpark and charge,\u201d eliminating the need for both repeated plugging or unplugging of cables as well as exposed metal contacts and power ports.\u00a0<\/span><\/p>\n

The result? Wirelessly charged micromobility solutions made for reliable, public use in today\u2019s smart cities.<\/span><\/p>\n

The Challenge: Create a Better Charging Solution for eBikes & eScooters<\/span><\/h2>\n

For micromobility operators, the solutions available for charging their eBikes and eScooters was a major pain point. Between wired charging and swapping batteries, both had their drawbacks.<\/span><\/p>\n

Traditional wired charging has high operational overhead due to labor costs and wear-and-tear on the cables and charging ports. Meanwhile, <\/span>battery swap<\/span><\/i>\u2014where a used battery is manually removed and replaced with a fully charged battery, is a costly capital expense for the operators on the <\/span>spare<\/span><\/i> batteries required for their deployed vehicles.<\/span><\/p>\n

Voltraware saw an opportunity to improve on the approach to charging electric micromobility devices in today\u2019s smart cities.<\/b><\/p>\n<\/blockquote>\n

Specifically, they sought to offer wireless power ICs and hands-free low maintenance wireless charging solutions to innovative companies for the design and integration of wireless power enabled eBikes and eScooters.<\/span><\/p>\n

This goal would allow micromobility operators to utilize wireless charging hands-free and at a distance without the need for precise alignment between the transmitter and receiver. Rather than wires or battery swaps, the approach utilizes a Power Transmitting Unit that operates in magnetic resonance with a Power Receiving Unit to achieve wireless charging in a “beneath charging” configuration. In addition to addressing a primary pain point of micromobility operators, the technology also provides an improved user-experience for customers.<\/span><\/p>\n

The Solution: A Two-Part System Utilizing AirFuel Resonant Technology<\/span><\/h2>\n

Voltaware brought together its IC, application, and marketing teams to identify an approach that would raise the bar on technology within the micromobility sector. To start, they chose Voltraware’s <\/span>VW8000 wireless power controller IC<\/span><\/a><\/span> together with an innovative coil design and system design.<\/span><\/p>\n

Then, integrating AirFuel Resonant technology, they built a two-part system that works in tandem to provide wireless charging to the solution. A T32 Power Transmitting Unit sits inside a charging pad enclosure on the ground, while a R32X series Power Receiving Unit resides inside a vehicle side enclosure under an eBike’s motor. Working as a pair, the system not only achieves eBike and eScooter wireless charging, but also does so at a longer coil-to-coil distance than required by the “beneath charging” configuration. <\/span><\/p>[\/et_pb_text][et_pb_image src=”https:\/\/airfuel.org\/wp-content\/uploads\/2023\/04\/Primary-scaled.jpg” title_text=”Primary” _builder_version=”4.20.4″ _module_preset=”default” width=”90%” module_alignment=”center” global_colors_info=”{}” theme_builder_area=”post_content” hover_enabled=”0″ sticky_enabled=”0″][\/et_pb_image][et_pb_text _builder_version=”4.20.4″ _module_preset=”default” global_colors_info=”{}” theme_builder_area=”post_content”]

With this solution, Voltraware was able to directly address the needs of the micromobility market. Gary Chi, Director of Technical Marketing at Voltraware explains,<\/span><\/p>\n

\u201cThe idea of wireless charging for Shared MicroMobility vehicles is to introduce <\/b>Opportunistic and Hands-Free<\/i><\/b> battery charging into the shared ecosystems of the operators. The goal of wireless charging is to increase the utilization rate of the shared vehicles while extending the lifecycle of their batteries \u2013 two of the biggest levers the shared operators can pull for profitability!\u201d\u00a0 – Gary Chi, Voltraware<\/b><\/p>\n<\/blockquote>\n

The solution is compatible with 36V, 48V, or 52V eBike battery systems with just four easy steps:<\/span><\/p>\n

    \n
      \n
    1. Determine the Z Level of your Power Receiving Unit.<\/b> Z Level is the measured distance from the charging surface of the PTU to the underside of the PRU (typically referred to as the \u201ccoil-to-coil\u201d distance).<\/span><\/li>\n
    2. Determine the Power Class of your Power Receiving Unit.<\/b> There are 3 Power Classes for the Power Receiving Unit: PC1 = 80W, PC2 = 150W and PC3 = 250W.<\/span><\/li>\n
    3. Determine the Charging Voltage of your Power Receiving Unit.<\/b> What is the DC output voltage of the battery pack used for your eBike or eScooter?<\/span><\/li>\n
    4. Select an Interoperable Power Transmitting Unit for your Power Receiving Unit. <\/b>From STEP 1 \u2013 3, the Z Level, Power Class, and Charging Voltage have been determined for the Power Receiving Unit.\u00a0 The Power Transmitting Unit\u2019s Z Level and Power Class shall be equal or greater than the Power Receiving Unit.<\/span><\/li>\n<\/ol>\n<\/ol>\n
