Key facts
- Workplace EV charging utilization above 30% can result in drivers unable to find open chargers.
- ChargePoint is developing cheaper Level 2 chargers for North America.
- ChargePoint is partnering with Eaton for smart breaker technology to enable bidirectional charging.
- Widespread vehicle-to-grid (V2G) technology requires standardization among automotive industry and electrical utilities.
- Most current vehicles are only DC bidirectional, not AC bidirectional, which is needed for home solutions.
A report indicates that electric vehicle charging infrastructure, particularly in workplace settings, is approaching a utilization limit that could hinder adoption. According to Wilmer, a workplace scenario with five-day, eight-hour workdays sees drivers unable to find an open charger when utilization exceeds 30 percent. This situation can arise when companies install chargers to meet employee demand, leading to more employees purchasing EVs, which in turn increases charger demand beyond capacity.
ChargePoint has introduced a new line of more affordable and powerful Level 2 chargers for the North American market. The company is also collaborating with Eaton, integrating its smart breaker technology to facilitate bidirectional charging. This development aims to make vehicle-to-home (V2H) solutions more accessible for consumers, enabling them to power their homes during outages. More advanced vehicle-to-grid (V2G) applications, where EVs can send energy back to the grid, are also envisioned.
However, Wilmer believes that widespread V2G adoption hinges on greater standardization within the automotive industry and among electrical utilities. A key requirement is the availability of AC bidirectional-capable vehicles, as most current EVs only support DC bidirectional charging. DC bidirectional solutions for homes are currently expensive and physically large, making AC bidirectional capability in vehicles a necessary step for broader consumer acceptance.
