A 30kW DC fast charger<\/strong><\/a> supplies direct current to an EV’s battery at up to 30 kilowatts \u2014 faster than AC Level 2 charging but below the 40kW-and-up tier most fast-charging hardware targets. It’s a rating some buyers search for, yet few manufacturers, TREASURE included, currently build a dedicated 30kW model.<\/p>\n

What “30kW” Actually Controls<\/h2>\n

Rated power tells you the ceiling, not what a vehicle will actually pull. A 30kW-rated unit delivering its full output for one hour adds roughly 30kWh to a battery \u2014 but only under conditions that rarely hold for a full session. Two things cap real-world speed regardless of what the charger is rated for:<\/p>\n

    \n
  1. The vehicle’s onboard DC acceptance limit, which is fixed by the automaker and often lower than the charger’s maximum output for light-duty EVs.<\/li>\n
  2. The battery’s state-of-charge curve, which tapers charging current sharply above roughly 80% SOC to protect cell health.<\/li>\n<\/ol>\n

    This is the edge case worth flagging before comparing hardware: a 40kW-rated charger paired with a vehicle that only accepts 25kW DC will charge at 25kW, not 40kW. Rated power is a spec sheet number, not a promised delivery rate \u2014 a distinction that matters more when shopping by kW figure alone than when comparing actual project throughput.<\/p>\n

    TREASURE’s Disclosed Power Tiers, and Where 30kW Would Sit<\/h2>\n

    TREASURE’s published DC charging<\/a> lineup clusters around a handful of standard ratings rather than offering every increment. Here’s what’s currently listed:<\/p>\n\n\n\n\n\n\n\n
    Product Line<\/td>\nPower Options<\/td>\nInput\/Output RangeProtection RatingStructure<\/td>\n<\/tr>\n
    Portable EV DC Charger (National Standard)<\/strong><\/td>\n6.6kW, 7kW, 20kW<\/td>\n90\u2013265V \/ 90\u2013280V \/ 265\u2013475V input<\/td>\nIP44<\/td>\nPortable<\/td>\n<\/tr>\n

    A 30kW model would land in the gap between the top of the portable series (20kW) and the bottom of the V2V series (20kW) \u2014 close enough to both that buyers researching “30kW” are usually better served by comparing those two tiers directly than waiting for an exact match.<\/p>\n

    Choosing Between 20kW and 40kW When 30kW Isn’t on the Shelf<\/h2>\n

    For a buyer whose calculated need lands near 30kW, the practical question isn’t which SKU says “30” \u2014 it’s which adjacent tier absorbs the gap with the least compromise.<\/p>\n

      \n
    1. Estimate the charging window available at the site (overnight dwell time, mid-shift break, or continuous public access) and back into a kW requirement from that.<\/li>\n
    2. Check the target vehicle’s or fleet’s onboard DC acceptance rate before assuming either tier will be fully utilized \u2014 many light-duty EVs cap well under 40kW regardless of what the charger can supply.<\/li>\n
    3. Decide whether bidirectional transfer matters. TREASURE’s V2V series<\/a> supports bidirectional energy transfer<\/strong> according to the selected configuration; the portable series does not.<\/li>\n
    4. Confirm the connector standard needed for the target market \u2014 CCS, GB\/T, and other project-configured interfaces are available depending on the product line, but not uniformly across every model.<\/li>\n
    5. 5.Submit application scenario, required power, and grid conditions for a project-specific quote, since none of these power tiers carry a published retail price.<\/li>\n<\/ol>\n

      Rounding up to 40kW generally costs less in engineering complexity than trying to derate a 20kW unit past its ceiling. Rounding down to 20kW keeps footprint and input-voltage requirements lower, which matters more at sites with constrained grid capacity \u2014 the same constraint that pushes some buyers toward mobile or portable charging equipment in the first place, since redeploying capacity avoids the civil works a fixed pedestal installation requires.<\/p>\n

      Protection Ratings and Certification Status<\/h2>\n

      The 6.6kW\/7kW\/20kW portable series carries a disclosed IP44 rating, suitable for a portable structure but lower than the IP54 or IP67 ratings shown on TESOURO<\/a>‘s larger fixed and cabinet-based products. IEC 60529 defines what IP44 actually covers (limited solid-object and splash protection) \u2014 worth checking against a site’s outdoor exposure before assuming any IP rating on one product line applies to another. No CE, UL, or other product-specific certification is claimed here; certificate names, numbers, and issuing bodies for any of these models are not publicly verifiable and would need confirmation from original certificate files before being referenced in a procurement decision.<\/p>\n

      FAQ<\/h2>\n

      Does TREASURE sell a 30kW DC fast charger?<\/h3>\n

      Not as a standalone catalog model currently. The closest published options are the 20kW unit in the Portable EV DC Charger series and the 20kW\/40kW tiers in the V2V DC Charger series.<\/p>\n

      Can a 40kW charger be configured to output 30kW instead?<\/h3>\n

      Configuration within a unit’s rated range depends on BMS\/EMS settings and project requirements \u2014 this should be confirmed directly with TREASURE’s project engineering team rather than assumed.<\/p>\n

      What connectors are available across these power tiers?<\/h3>\n

      CCS, GB\/T, and other project-configured interfaces, depending on the specific product line \u2014 not every connector option is available on every model.<\/p>\n

      \u00a0Why does a 40kW charger sometimes charge slower than expected?<\/h3>\n

      The vehicle’s onboard DC acceptance limit and its battery’s state-of-charge curve both cap real delivery speed independent of the charger’s rated maximum.<\/p>\n

      \u00a0Is pricing available for any of these models?<\/h3>\n

      No product-level price range is published. Quotes are prepared after a buyer submits power, capacity, and site requirements.<\/p>\n
