building the charging piles for electric vehicles, the trend is to use AC charging for the core and DC charging to complement it. The AC charging station supplies AC-controlled power to the vehicle-mounting charger of electric vehicles, and thus has stricter requirements for current, temperature, and voltage of the connectors.
The economics for electric trucks in long-distance applications can be substantially improved if charging costs can be reduced by maximising "off-shift" (e.g. night-time or other longer periods of downtime) slow charging, securing bulk purchase contracts with grid operators for "mid-shift" (e.g. during breaks), fast (up to 350 kW), or ...
