The exponential growth of EVs has led to an increase in energy demand, burdening the electrical infrastructure. However, smart EV charging creates a win-win scenario for balancing the demands of EV charging and the grid.

How does smart EV charging work?

Smart EV charging is all about connecting charging points with users and operators. Every time an EV is plugged in, the charging station sends information (i.e. charging time, speed, etc) via Wi-Fi or Bluetooth to a centralized cloud-based management platform. Additional data may also be sent to this cloud. This can include, for example, information about the local grid’s capacity and how energy is currently being used at the charging site (house, office building, supermarket etc.). The mass of data is automatically analyzed and visualized in real-time by the software behind the platform. It can then be used to make automatic decisions about how and when EVs are charged.

Smart EV Charger comes in three forms – V1G, V2G, and V2H-B.

V1G – unidirectional, controlled charging, where charging infrastructure adjusts its rate of charging, based on grid requirements.

V2G – vehicle-to-grid charging, where the vehicle’s battery is used to return energy to the grid during periods of high demand, and the vehicle is charged during off-peak times. The vehicle remains connected, and the smart charging management system adjusts the direction accordingly.

V2H-B – Vehicle to home or building, where the stored energy within the vehicle’s battery provides power to the home or building, based on the immediate requirements. Again, the battery is recharged when demand is reduced.

Smart EV Charger also provides significant benefits to the EV charging ecosystem as a whole – from the utility to individual EV drivers.

• No need to connect to the Internet

The biggest advantage of the BLE solution is that the charging pile does not need to be connected to the Internet. It also does not require complicated wiring.

• Strong flexibility

The smart EV charger has strong flexibility and low construction cost. It effectively solves the transformation and upgrading of new/old residential areas or the decentralized laying of charging piles on the roadside.

• Eco-friendly and Cheap

For individual EV drivers, smart EV charging’s greatest incentive is cheaper, eco-friendly, and safer charging.

RF-star BLE module can work as the most important part of smart EV charging to transmit the data. The BLE solution of smart EV charger assists charging pile manufacturers, operators, and commercial charging service providers to realize the intelligent, digital, and networked chargers.
