6.26 MWh DC Battery Container for EPC Auxiliary-Power Planning

Equipment model: YT-Container ESS-6.26MWh. This page describes the stated configuration or application review. Final supplied equipment and project interfaces follow the confirmed technical agreement.

Auxiliaries are a separate design package

This application review addresses the AC auxiliary services needed around a DC battery container. The YT-Container ESS-6.26MWh provides a 6.26 MWh LFP battery block rated at 1.56 MW DC charge/discharge. Its battery output does not establish an AC supply for thermal management, cabin services or external site loads. Identify the auxiliary source, distribution boundary and start-up sequence in the EPC design.

Distinguish thermal performance from electrical demand

The source lists 30 kW cooling and 12 kW heating for the liquid-cooling system. These are thermal capacities, not electrical feeder loads. Do not add them together to size a breaker or to claim auxiliary power consumption. Obtain actual rated and maximum input demand, starting/inrush characteristics, operating modes and protection requirements from the supplied equipment schedule. Seasonal auxiliary energy should then be included in the plant efficiency and delivered-energy assessment.

Check voltage, frequency and source continuity

The chiller supply is 380-415 V AC, 3N~, 50 Hz. The electrical-cabin air conditioner uses 230 V AC +/-15%, 50 Hz; the stated 1 kW is its cooling capacity. The dehumidifier is listed at 220 V, 50 / 60 Hz. A 60 Hz project cannot assume the 50 Hz equipment is compatible. Request an approved auxiliary configuration for the destination supply. Define what happens when auxiliary AC is lost, which controls remain powered and how the battery reaches its approved safe state.

UPS, acceptance and YINTU coordination

The electrical cabin includes a 3 kVA UPS. That rating alone does not define autonomy or guarantee power to all thermal equipment. Confirm supported loads, battery autonomy, alarms and restoration testing with the manufacturer. YINTU is a solution provider coordinating battery equipment and technical interfaces with manufacturing partners. The agreed scope should identify external PCS, auxiliary transformer or supply, AC distribution, plant EMS, switchgear and commissioning duties. Use an approved auxiliary load list and single-line diagram for acceptance.

Frequently Asked Questions

Does the 30 kW cooling figure describe electrical consumption?

No. It is a thermal cooling capacity. Electrical demand and starting conditions must come from the actual chiller data for the offered configuration.

Can the standard auxiliary package operate on a 60 Hz supply?

The source chiller and cabin air conditioner are listed for 50 Hz. Compatibility or an alternative package requires explicit manufacturer confirmation before ordering.
