Electric vehicle wireless charging based on inductive power transfer technology

Recently, the British HaloIPT company announced in London that it has successfully realized the wireless charging of electric vehicles by using its newly developed inductive power transmission technology. This is a technology that may change the direction of electric vehicles. It is reported that HaloIPT plans to establish a commercial scale demonstration base for this inductive power transmission technology by 2012.

HaloIPT's new wireless charging system embeds wireless charging pads in underground parking lots and streets. It only needs to be equipped with a power receiver pad to wirelessly charge the car.

So far, electric vehicles such as G-Wiz, Nissan Leaf and Mitsubishi i-MiEV have to be connected to a street car charging station or a household plug through a wire to be charged. The system uses a magnetic field instead of a cable to induce electricity. HaloIPT engineers say the potential of this technology is huge because inductive charging can also be on the street, which means that electric vehicles can be charged while parked or waiting for traffic lights. Special wireless charging pads can also be placed on a variety of roads, which allows electric vehicles to achieve mobile charging. Moreover, this flexible mobile charging technology is the most effective way to solve the travel problems faced by electric vehicles today, and it will greatly reduce the requirements on the battery model.


HaloIPT says this is also an effective way to deal with the so-called "charge anxiety." With an inductive power transfer system, car drivers don't have to worry about sometimes forgetting to charge an electric car.

HaloIPT's wireless charging pad works under asphalt, underwater or ice and snow layers and is well tolerated for parking shifts. The inductive power transfer system is configured to power small road vehicles as well as a variety of road vehicles such as heavy goods vehicles and buses.

HaloIPT claims that their charging system supports a larger lateral sensing range, which means that the car's power receiver pad does not need to be placed directly above the wireless charging pad. The system is also said to provide a charging distance of up to 15 inches, even with recognition capabilities, for example, when small things (such as kittens) interfere with the charging process, the system can handle it.

Although the implementation of such a system will be an expensive project, HaloIPT believes that the future of the embedded wireless charging system will become the development direction of electric vehicles. This is possible and certain, but it is still quite far from being widely implemented. Despite this, HaloIPT's motto - "No plugs, no fuss, just wireless" - still gives us hope: one day, electric car charging will take place during driving.

About Inductive Power Transfer System

The mains supply is provided by alternating current and is used to supply a lumped loop with a current range from 5 amps to 125 amps. Since the lumped circle is inductive, it is necessary to use series or parallel capacitors to reduce the operating voltage and operating current in the power supply circuit.

The power receiving pad coil is magnetically connected to the main power coil. Power transfer is achieved by adjusting the operating frequency of the receiving pad coil to coincide with a main power supply coil with a series or parallel capacitor. A switch controller can be used to control power transfer.

Battery Management System (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its Safe Operating Area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and / or balancing it.

A battery pack built together with a battery management system with an external communication data bus is a smart battery pack. A smart battery pack must be charged by a Smart Battery Charger.
