ChargePoint Express Plus offers DC charging at up to 400 kW

ChargePoint, which operates over 31,000 independently owned public charging stations around the world, has announced a higher-level DC charging solution designed to accommodate the coming generation of longer-range EVs. ChargePoint Express Plus can deliver up to 400 kW, plenty of power to charge new EVs such as the Chevy Bolt at their maximum rates, as well as upcoming models such as the Tesla Model 3.

Express Plus features a modular design to allow site owners to incrementally build out charging infrastructure, adding capacity to meet future demand. The system intelligently allocates power among vehicles, charging each car as quickly as possible while making efficient use of the power available at each site.

ChargePoint has also introduced Express 250, a standalone DC fast charging station capable of adding 90 miles of range in 30 minutes.

“Express Plus is a platform built to support ChargePoint’s vision for the future of DC fast charging: ultra-fast, scalable and incredibly efficient charging that’s conveniently located where drivers need it for long trips,” said Pasquale Romano, CEO of ChargePoint. “Express Plus charging centers can start small and grow as needed by adding charging capacity without further construction.”

Express Plus will be available in July.

    So this is a somewhat interesting article in what it DOESN’T say.

    Almost as a footnote, it mentions the Express 250 standalone DC fast charging station capable of adding 90 miles of range in 30 minutes.

    That sound awfully UNimpressive, so I took a look at the specs.

    It looks like the STATION is capable of delivering 62.5 kW of power. Reading between the lines, it looks like the station would be capable of delivering all 62.5 kW to one connector, or sharing 31.25 kW among the two connectors simultaneously.

    The Express Plus system is capable of hooking two stations together so you could theoretically get 2 x 62.5 kW to a single vehicle (provided the connector & the vehicle supported it, and no other vehicles were charging), or you could add one of the cubes to get an additional 500 kW of power available (although you would most likely be sharing a cube among a large number of stations). The maximum power flowing through a single station would be 400kW (again, provided there was no sharing going on that would reduce the power below 400kW).

    I wonder if the connectors could even handle that level of power? I suppose the system is future proofed, but at some point new connectors may have to be added to allow for such high power transfer.

      Can you imagine the demand charges on 15 minutes of 400kW charging! The challenge (in CA) is going to be figuring out how to monetize the cost of the charging in a way that is profitable. Maybe a loss leader?

      • Lance Pickup

        Yeah, there is no way this will be feasible without some kind of stationary storage coupled with it to mitigate demand fees. That’s the only way you could even get close to monetizing, or even minimizing losses in an environment where you could even operate it as a loss leader.

          Why shouldn’t stationary storage automatically be a solution? Seems feasible and, for now, best solution. Add solar and it helps to relieve the grid, too.

          • Lance Pickup

            Totally agree. Wasn’t implying that it would be unsuccessful because of no stationary storage. On the contrary, my original post assumed that station storage would be part of the solution.
