EVs: Can they help defer costly reinforcements?

Petrol stations will give way to commercial and public charging stations, and corporate packages to enable employees to charge while working will have become the norm. If brought to reality, the electric vehicle (EV) revolution will play a major role in enabling the country’s decarbonisation targets to be achieved, but it will not come without its challenges. For every internal combustion engine that is replaced by electric or plug-in hybrid, emissions will be reduced, but pressure on the electricity grid will increase.

Examining blockchain

A blockchain is a decentralised data-ledger technology. That is, there is no central database, rather databases are held by multiple computers, each with an identical copy of the data. The system is maintained by a network of computers, in which successive data (in blocks of records) are first validated through a network consensus approach, and then added to the ledger. Each block in the chain contains a set of transactions represented by a hexadecimal ‘fingerprint’ known as a ‘hash’. This hash is passed on to the next block, thus creating the chain of blocks (see Figure 1 below). This enables computers on the network to easily verify whether any data in a block has been tampered with since altering the data within a block would affect its hash. The computers (called ‘nodes’) that participate in the network receive a complete copy of the blockchain, and stand as proof of every transaction ever executed on that particular system. The mutually validating network of nodes protect the coherence and integrity of the network and in doing so, avoid the need to use intermediaries to centralise all the data.

EV smart charging marketplace trial launched

According to the network operator, customers and the wider EV industry have told electricity networks that they are strongly in favour of giving people choice about how and when they charge. Shift is hoping to answer questions such as how smart charging could unlock the financial, environmental and social benefits of customers charging their electric vehicle during off-peak hours.
