EV charging in underground carparks is hard. Blockchain to the rescue

 I love the utilization of technology like blockchain and distributed ledgers, but only it solves real-world problems. I recently sat down with Nikhil Bharadwaj, co-founder, and CEO of electric vehicle charging company Xeal, to find out a couple of problems that had plagued the company’s period.

They were installing chargers at apartment buildings in underground parking garages. However, this can be an area where it’s challenging to realize Wi-Fi internet connectivity. Telcos told them the sole solution was for either the building owner or themselves to pay tens of thousands for an IT upgrade. They did this reluctantly for an early customer, yet wanted a higher solution.

According to the concrete and steel environment effectively acted as a “Faraday cage,” which meant that the EV chargers wouldn’t share with people’s mobile Devices after they will try to initiate charging then Damage. You could end up stranded, unable to charge your car. “So we had to innovate.”Ok, I assumed they may be telling me about their use of wave tech or LiFi, but they need to come up with something lots more interesting.

NFC and blockchain solve a real-world problem:

Their solution could be a patent-pending self-reliant connectivity blockchain protocol called Apollo, which, combined with NFC, allows charging stations and smart devices to be deployed anywhere, even within the most rugged environments.

The company calls it the world’s first ‘No Internet for Things.’

I’m always fascinated by the solution to the question ‘Why now?’ and Bharadwaj explained the three inflection points that successfully came together in 2020:

Pressure on Apple to create NFC chip technology available to third-party developers brought the employment of NFC into the broader consciousness.
Contactless installments during COVID turned out to be more hearty and all the more broadly taken on. Wider adoption of Distributed Ledgers.
Xeal has attracted lots of interest from investors. the corporate raised $14 million in seed and VC funding earlier this year. Let’s take a glance at their tech:

How Xeal charging works :

Similarly, as with any EV charging, an installment application interfaces your vehicle to the EV charger. With Xeal, the employment of NFC means the sole time you would like the web is to download the app within the first instance to make a profile that has their personal and vehicle information and payment details.

You then, at that point, get a cryptographic token on your versatile that confirms your personality and empowers you to get to all of Xeal's public charging stations. The token is time-bound, which proposes it disintegrates after use. To charge your vehicle, you hold your telephone up to the charger. Your mobile reads the cryptographic token, automatically mentioning an NFC scanner. It opens the app, authenticates your charging session, starts scanning, and within milliseconds, the charging session starts.

All of this is often without Internet access — it’s a control system without SIM cards or ethernet cables. So, why can’t you simply use NFC without blockchain? The blockchain, or specifically the distributed ledger, is employed to record the specifics of the charging session.

As Bharadwaj explained:

We need to understand how long they were there and the way much energy they consumed.
When the person finishes charging, they tap their phone to the charger to finish the session.
From this, the phone receives the ledger, and that they go back or return to figure or wherever their phone’s connected. this is often essentially a delayed gateway. Your phone is that the gateway to the cloud. and every one the processing happens within the background. The user never has got to open the app. It’s all tired of the background.

At the point when the client next gets to WiFI, the client gets another token. All the more significantly, the central matters of their charging meeting – whether or not they neglected to close – are disseminated to other clients' telephones inside the organization. Accordingly, whether or not one telephone neglects to reconnect to Wi-Fi, different telephones can refresh the record over the organization.

As Bharadwaj detailed:

You can consider them as a flock of birds that are all lecture one another. and every one it takes is one user to interact to herald the last ten records or transactions onto the distributed ledger. This includes instances where users might not have tapped to finish or if your phone dies.

Security:

One of the foremost significant pain points for EV charging is security. A cybercriminal could use multiple entry points to trigger an attack after you charge an EV– these range from charge point operators to payment providers, utility companies, and third-party vendors.
EV chargers are particularly susceptible to “man-in-the-middle” attacks. These are cyberattacks where an aggressor transfers or changes correspondence between two gatherings. this permits the attacker to relay communication, listen in, and even modify what each party says.

Cybercriminals use these attacks to access personally identifiable information and steal MasterCard information. Last year, security scientists SwRI fostered a "man-in-the-center" gadget that ridiculed signals between a charger and vehicle. It could overcharge and undercharge the battery, potentially leading to big safety problems.
With Xeal, explained Bharadwaj, the utilization of NFC means to access the charging network, you would like to be at the location, at the placement of the device, and be within one inch to pay attention in on any communication."We're not going anyplace outside of the charger and furthermore the telephone.'

Further, Distributed Ledger Technology is synchronized and accessible across different sites and geographies by multiple participants — during this instance, all the users of Xeal.
Distributed ledgers are inherently harder to attack than centralized networks because all of the distributed copies have to be attacked simultaneously for them to achieve success. Further, these records are immune to malicious changes by one party.

The start of larger things to come:

Range anxiety could be a huge problem that deters people from transitioning to electrical vehicles. I find Xeal interesting as they hit a critical intersection that has emerged not just for EV charging. As more devices hook up with the net and machine-to-machine interactions become mainstream reliable connectivity is crucial.

In keeping with Bharadwaj that company has also attracted interest from shared mobility scooters and smart door lock companies.

This is the second part of a series I’m writing about Web 3.0 and blockchain technology in mobility. I’m attempting to cut back the jargon and specialize in the issues the tech aims to resolve. try the primary piece where I dive deep into how one motorbike company uses blockchain technology for P2P trading.
