Buying containerised mobile charging equipment from China is straightforward on the technical side and less so on the commercial side. Product certification, battery transport documentation, warranty structure and the service route all need settling before the order, because they are difficult to renegotiate afterwards.

MPMC POWERTECH CORP. manufactures containerised and trailer-mounted mobile charging equipment as its BCH Series, documented at 80 kW to 600 kW DC output with 70 kWh to 1,075 kWh of onboard storage. This article sets out what an import-focused evaluation should cover.

Certification Is Model-Specific and Market-Specific

The most common misunderstanding in this segment is treating certification as a supplier attribute. It is not. It applies to a specific model in a specific market, and a supplier holding a certificate for one model does not automatically hold it for another.

MPMC’s published certification list is set out below. Which entries apply to a given order should be confirmed against the exact model and destination.

Level	Listed certifications
Company	ISO 9001:2015, ISO 45001, ISO 14001, CNAS-accredited testing centre at Haimen, ARCADIS, ilac MRA, WMI
Product	CE, TUV, SGS, UN38.3 for battery transport, SABER for Saudi Arabia, France BV, Russian Customs Union, Nigeria SONCAP, China TLC, UL

Two entries deserve particular attention for this equipment.

UN38.3 is the transport test standard for lithium batteries. Without it, shipping a unit containing a large battery is impractical. Confirm the report exists for the cells in the offered configuration, not for a similar product.

Market-specific certificates such as SABER, SONCAP and the Russian Customs Union documents are usually what determines whether goods clear customs. These should be confirmed early rather than at shipment.

Transport and Delivery Planning

Container format simplifies shipping but does not remove the planning.

Weight and handling

MPMC lists the BCH-500-1000 at 19,800 kg in a 20 ft GP format, the BCH-800-600 at 15,000 kg and the BCH-600-400 at 8,300 kg, each loading one unit per 20 ft container. The trailer-mounted BCH-275-200 is listed at 2,800 kg with four units per 20 ft container.

Crane or heavy forklift access, ground bearing and the delivery route to the final position should be confirmed before the order, not on arrival.

Battery state during shipment

Lithium batteries ship at a controlled state of charge. Confirm the arrangement with the supplier and whether any action is required on arrival before commissioning.

Commissioning responsibility

Confirm who commissions the unit, whether travel is included, and what remote support is available. MPMC lists an EMS with 4G connectivity across the BCH range and an open API, which is the mechanism for remote diagnosis.

Matching the Format to the Deployment

Container format is not automatically the right answer, and the alternative within the same range is often a better fit.

Deployment pattern	Format to review	Reason
Fixed position for a long period, lifting equipment available	Container format, BCH-600-400 and above	Higher onboard capacity, outdoor-rated, one-time positioning
Frequent relocation between sites	Trailer-mounted BCH-275-200	2,800 kg with a 3.5 t heavy-duty trailer and integrated forklift hole
Multiple small sites served by one asset	Trailer-mounted BCH-275-200	Four units per 20 ft container for import, and towable between positions
Central hub with more than 1 MWh reserve	BCH-500-1000	1,075 kWh onboard with 500 kW AC output available in parallel

The Product Range in Detail

Model	DC charging output	Battery capacity at 25°C	AC input rated power	DC connectors	Weight
BCH-80-70	80 kW	70 kWh	70 kW DC input	CCS2 260 A × 1	880 kg
BCH-275-200	150 kW	203.5 kWh	80 kW	CCS2 250 A × 2	2,800 kg
BCH-600-400	400 kW	407 kWh	280 kW	CCS2 350 A × 2	8,300 kg
BCH-800-600	600 kW	610.6 kWh	280 kW	CCS2 350 A × 2	15,000 kg
BCH-500-1000	500 kW	1,075 kWh	560 kW	CCS2 350 A × 2	19,800 kg

MPMC lists CCS2 as the standard connector, with optional CCS1, GB/T and CHAdeMO for specific markets. Confirm the connector requirement at the enquiry stage, because it affects the build rather than being a field-changeable item.

Warranty and Service Structure

Warranty terms in this segment are usually expressed in two dimensions, and both need reading.

MPMC’s published terms for the BCH-275-200 and above list a system warranty of 3 years or 1.6 MWh/kWh total output, whichever comes first, with a battery performance warranty of 5 years or 2.57 MWh/kWh and end-of-life capacity retention of at least 70%. The BCH-80-70 is listed separately at 1 year or 60 MWh total output, with a 3-year or 200 MWh battery performance warranty.

The throughput dimension matters more than the calendar dimension on a heavily used unit. A high-utilisation deployment may reach the energy limit well before the year limit, which changes the effective cover.

Confirm separately what is excluded. Labour, travel and airfreight are commonly outside the scope unless agreed in the contract.

Documented Deployments

Location	Configuration	Application
Netherlands	BCH-275-200 and BCH-500-1000	Grid-connected EV charging for port and logistics operations
United Kingdom	BCH-275-200 × 8 units	Port logistics where the local grid limited EV truck charging
Norway	BCH Series, 2 MWh total; 500 kW and 1,000 kWh per unit	Off-grid construction machinery charging

An Import Timeline

Most difficulties on imported charging equipment come from items closed too late. The sequence below is ordered by when each has to be settled.

Stage	What has to be closed	Consequence of delay
Before the enquiry	Connector standard and DC voltage window	These affect the build, not the configuration
At quotation	Which certificates apply to the exact model and destination	Certification cannot be added retrospectively
At order	UN38.3 documentation for the cells in the offered configuration	Shipping a large battery without it is impractical
At order	Warranty text, both dimensions, with exclusions	Difficult to renegotiate afterwards
Before shipment	Battery state of charge arrangement, and any action needed on arrival	Affects commissioning readiness
Before shipment	Handling equipment, ground bearing and delivery route	MPMC lists 19,800 kg for the BCH-500-1000, 15,000 kg for the BCH-800-600
Before arrival	Commissioning responsibility and travel arrangements	Determines whether the unit works on day one
At handover	Spare parts list, lead time and shipping route	Sets the recovery time for the first failure

MPMC’s published certification list covers CE, TUV, SGS, UN38.3, SABER, France BV, Russian Customs Union, Nigeria SONCAP, China TLC and UL, applying by model and market rather than across the range.

The Clause Most Often Missing

Warranty documents in this segment usually state what is covered. Fewer state clearly who travels.

MPMC’s published warranty for the BCH-275-200 and above is 3 years or 1.6 MWh/kWh total output with a 5-year or 2.57 MWh/kWh battery performance warranty, and the general after-sales position excludes labour, travel and airfreight unless agreed in the contract.

For an imported unit, that exclusion is often the largest part of a repair cost. Two questions are worth putting in writing before the order: which faults can be diagnosed and cleared remotely through the EMS, and what the commercial arrangement is when they cannot.

A supplier willing to answer both specifically is offering a support model. One that answers with a service network map is offering a brochure.
