A really fascinating electrical ferry was lately commissioned for service in Bangkok, Thailand. It is known as MINE Sensible Ferry, the place MINE is for “Mission No Emission”.
In response to Vitality Absolute, which constructed the ferry, the ship is supplied with an 800 kWh lithium-ion battery and may take 235 passengers (104 seats plus 131 standing). The working pace is 11.0 knots (12.7 mph; 20.4 km/h), whereas the utmost is 15.0 knots (17.3 mph; 278 km/h).
On the roof, you possibly can see some photo voltaic panels to generate an extra, comparatively minor quantity of juice, however our consideration was caught primarily due to the charging.
There are such a lot of charging inlets and plugs that within the first second, we thought that somebody was trolling us. One plug, two plugs, three plugs… 4, 5, 6, 7… and what? One other 7!
…and one other 7, and one other 7 (truly 5 with two slots empty). A complete of 26 CCS2 DC quick charging inlets and plugs to conduct quick charging in 15-20 minutes.
That is hilarious! Remarkable! The ferry mainly takes all of the plugs at any charging station, it visits, so possibly we must always add a brand new time period of being FERRIed.
Having so many plugs to attach and disconnect may require a full-time worker, we guess. Particularly if there can be a fleet of such ferries working round.
Being extra critical, we’re actually undecided why the corporate opted for such an answer. A fundamental match with an 800 kWh battery and 15-20 minute charging signifies that the required charging energy is 2.4-3.2 MW (in all probability much less assuming no full discharge).
It is a lot of energy however not for 26 DC plugs! A single automotive CCS plug takes 500 kW and you should buy them instantly from varied suppliers (together with HUBER+SUHNER, Phoenix Contact and ITT Cannon). In different phrases, the variety of plugs is considerably too excessive.
There are in all probability additionally specialised greater energy connectors for prime energy, however at the very least in Europe, ships are getting excessive energy charging utilizing an automatic connection system. Listed here are examples from Norway and Sweden/Denmark:
At present, the automotive trade is engaged on megawatt-level charging techniques. Multiple prototypes were recently tested by the National Renewable Energy Laboratory (NREL). Daimler is constructing its first 1+ MW charging station for trucks on Swan Island in Portland.
Hopefully, quickly there shall be a typical answer for 1+ MW charging as a result of as we will see, there’s a want for it.
