Imagine your home's electrical panel can only handle a few big appliances at once, so you have to leave some off even if you have space. This technology acts like a super-smart traffic cop for electricity, switching power between cars so quickly that no energy is wasted. It lets you plug in way more cars using the same old wires without needing to dig up the street to install bigger cables.
Current EV charging controllers waste up to 2/3 of available grid capacity, forcing expensive and slow grid expansions to meet charging demand.
A charge controller and charger featuring uninterrupted load switching, wireless/PLC communication, and multi-point load management.
If you are a parking garage operator dealing with limited power capacity that prevents adding more chargers — this project developed a controller that uses the existing grid up to 3x more efficiently. This allows you to charge up to 6x more EVs simultaneously without expensive infrastructure upgrades.
If you are a fleet operator dealing with grid congestion at your depot — this project developed uninterrupted load switching technology. This enables you to charge up to 6x more vehicles using the same grid connection, avoiding the need for billion-euro grid expansions.
If you are an installer dealing with high labor costs for wiring communication cables between chargers — this project developed wireless and powerline communication (PLC). This makes installation more cost-effective because no separate communication cables are needed.
The project avoids the need for grid capacity increases which would otherwise cost billions and take decades. It achieves this through semiconductor and microcontroller technology instead of heavy infrastructure investment.
Yes, the system supports multi-point load management and can charge up to 6x more EVs simultaneously with the same grid connection.
Based on available project data, the technology is developed by MULTICHARGE OU (VOOL) and involves breakthrough uninterrupted load switching and wireless communication, though specific patent numbers are not listed.
The solution is compatible with industry standard protocols OCPP 1.6 and 2.0 for outside communication.
The project period ended on 2023-10-31, and first pilot units have already been manufactured and used by customers.
The project was executed by a single-partner consortium consisting of one Estonian SME, MULTICHARGE OU. This 100% industry-led structure indicates a strong focus on commercial application and rapid market entry rather than academic research.
