French explainer sets out how single phase and three phase supply shape onboard charger and home charging choices
By Eve
A French-language explainer says few sellers fully understand the issue, even though the choice of onboard charger and of home socket or charging station is critical. It states that the power actually achievable varies strongly depending on whether the vehicle and the charging point are designed for single phase or three phase current. It adds that the public grid is almost entirely three phase, but a home is usually supplied with one of the three wires, which is the vast majority of cases in France, where Enedis is the distribution network operator.
Why it matters
For French residential and small site projects, the supply type at the delivery point and the vehicle's onboard charger together cap real charging speed, so specifying hardware without checking both risks underperformance. Procurement teams and CPOs should confirm single phase or three phase supply at the outset to avoid mismatched expectations.

Instavolt to install ultra rapid chargers at selected Premier Inn hotels across the UK
Instavolt has signed a national framework agreement with Premier Inn's parent company to identify and deliver ultra rapid charging at well located Premier Inn sites, though the number of chargers has not been disclosed. The programme covers new ultra rapid chargers, upgrades to existing facilities, improved grid connections where required and clearer signage, with the sites open to non guests as well as hotel guests. The report puts Premier Inn at over 845 hotels across the UK and Ireland, and Instavolt at around 1,200 sites and some 4,250 chargers.
Why it matters
A framework route between a major hospitality landlord and a single operator shows how large property portfolios may be packaged for charge point operators, with grid upgrades folded into the delivery scope. With no volumes or timelines disclosed, the size of the pipeline remains unclear for suppliers and competing operators.
Zaptec reaches one million installed EV chargers worldwide
Norwegian charging manufacturer Zaptec has reached one million installed EV chargers worldwide, with the majority in Europe. According to LCP Delta, Zaptec holds approximately 10% of Europe's installed EV charging base across residential and non-residential charging, with leading positions in both segments. The company has focused on EV charging since 2016, expanding from shared charging to home charging and energy management, supported by local sales organisations, distribution partners and a European manufacturing network.
Why it matters
A one million installed base, with roughly 10% of the European market per LCP Delta, shows Zaptec has proven scale in homes, apartment buildings, workplaces and commercial properties. For procurement teams and CPOs, that track record and its European manufacturing and partner network are useful evidence when assessing supplier maturity and support capacity.
Load balancing presented as a way to charge more fleet vehicles without costly power upgrades
In a piece by Phil Wiltshire, contracts manager at Pensdown, the electrical contractor, the argument is that how electricity is distributed at a depot matters as much as the number of charging points installed. Vehicles often return at similar times, concentrating demand, and the number of chargers a site can support is frequently limited by its existing electrical infrastructure. The article positions load balancing as a realistic way to manage that demand without driving up electricity costs or investing heavily in extra power capacity.
Why it matters
For CPOs and installers bidding on depot work, load balancing is a lever for fitting more charge points within a constrained grid connection, which can avoid or defer costly upgrades. It also shapes how tenders should specify capacity, since charger count alone no longer defines what a site can deliver.
