Top 10 Energy Storage Battery Brands in Vietnam in 2025 by Shipments

CATL ranked first in Vietnam’s 2025 energy-storage battery-system shipment assessment, followed by BYD Energy Storage and Huawei Digital Power. LG Energy Solution, Sungrow, VinFast Battery, EVE, Energy Storage Vietnam, Great Power and Samsung SDI complete the top ten.

The first point for a buyer is the definition. This is a ranking of energy storage battery systems. The study counts systems that combine cells, BMS, PACKs, battery cabinets or complete storage-system delivery. Standalone cell trading is handled as a separate supply layer rather than a separate rank.

That distinction changes the result. CATL and BYD can be evaluated through both cell and system capability. Huawei and Sungrow enter the list mainly through system integration and packaged storage delivery. VinFast Battery and Energy Storage Vietnam represent local manufacturing or system-assembly routes. EVE and Great Power can appear through cell, battery-pack and channel supply.

For a Vietnam project, the useful question is: “Which part of the storage system does this brand supply, who integrates it, and who supports the system after delivery?”

How the Vietnam battery ranking was built

CVC’s 2025 Vietnam ranking combines third-party market research and Vietnamese energy media, public company disclosures, China-to-Vietnam export research, and local distributor and system-integrator evidence from Hanoi, Ho Chi Minh City and Vietnam energy-storage events.

The research basis includes the Vietnam battery-market study cited in the supplied report, Vietnamese energy publications, company filings and investor materials, export tracking, and local channel information. No public source provides a complete official brand-by-brand GWh table for the Vietnamese storage-system market. The list is therefore a cross-source shipment reconstruction.

Calculation rules

The 60/25/15 weighting follows the Vietnam market structure used in the study. It gives large projects appropriate influence while retaining the commercial and residential channels that matter to local distributors and installers.

Vietnam’s top 10 energy storage battery brands in 2025

Each row shows both shipment position and supply role, so buyers can see where the brand sits in the cell-to-system chain.

1. CATL: the largest system-shipment position in the study

CATL ranks first, with the supplied study estimating a 25%–30% share of Vietnam’s storage-battery-system shipments. This range is derived from cross-source evidence. Its position is supported by utility-scale storage, commercial systems and large renewable projects that require high-volume LFP battery supply.

CATL can be evaluated at two levels: the cell platform and the complete storage-system delivery. A project buyer needs to identify whether the quotation covers cells only, a battery container, a liquid-cooled system, BMS and controls, or the complete battery block supplied to an EPC.

The factory and system review should cover cell chemistry, cell format, rack configuration, DC voltage, continuous charge and discharge power, cooling, fire protection, EMS communication and long-term service. For a Vietnamese project, the system integrator and warranty entity must be written into the commercial offer.

2. BYD Energy Storage: cell, battery and system depth

BYD ranks second, with the study estimating a 15%–20% Vietnam share. Its strength comes from the depth of the BYD battery and energy-storage ecosystem. The product range reaches utility-scale container systems, commercial storage and residential battery cabinets.

The buyer should distinguish between a BYD cell, a BYD battery module, a Battery-Box family product and a larger packaged system. These products may sit in different supply routes and carry different installation, commissioning and warranty responsibilities.

For channel and project procurement, request the exact product family, usable energy, nominal voltage, maximum continuous power, expansion rules, inverter compatibility, BMS protocol and local service process. The same group can serve different markets through very different system architectures.

3. Huawei Digital Power: a system brand built around an energy ecosystem

Huawei ranks third through residential and commercial storage-system integration. The LUNA family gives Huawei a strong position in premium residential and small commercial projects where the customer is already using, or planning to use, Huawei solar equipment.

Huawei should be evaluated as an energy-storage system integrator in this ranking. The storage system is sold through coordinated inverter, battery module, monitoring and installation functions. The brand’s shipment position therefore reflects system delivery rather than standalone-cell manufacturing.

The quotation should identify the battery module, usable capacity, inverter family, backup output, communication path, firmware version, installer authorization and warranty territory. The battery and inverter matching guide explains why the system combination matters more than the battery logo alone.

4. LG Energy Solution: a premium route for residential and Korean-invested projects

LG Energy Solution ranks fourth and serves a premium segment in Vietnam. The study connects its position with high-end residential storage and Korean-invested industrial projects, where established battery credentials and corporate supply relationships influence the shortlist.

LG Energy Solution has both cell and battery-system capabilities. The exact chemistry and system format depend on the model and project. A quotation should therefore avoid generalising from the company name and should identify the exact battery platform, cell chemistry, system voltage, BMS and integration partner.

Buyers should confirm whether the supply is a complete system or a battery module, which inverter families are supported, who handles commissioning, what warranty territory applies and how replacement units are provided in Vietnam.

5. Sungrow: packaged battery delivery linked to power conversion

Sungrow ranks fifth in the battery-system assessment. Its position is driven by packaged battery and inverter delivery for commercial and utility-scale storage. This integrated route is valuable to project buyers that prefer coordinated power conversion, battery controls, EMS and commissioning.

Sungrow should be compared as a storage-system supplier rather than as a standalone cell brand. The relevant factory and project questions concern the battery system, PCS interface, cooling, fire protection, container layout, controls and after-sales responsibility.

Before ordering, ask for the battery-system architecture, usable capacity, DC voltage, continuous power, battery-inverter matching, communication map, fire-system scope, commissioning plan and service contact in Vietnam.

6. VinFast Battery: a Vietnamese local battery route

VinFast Battery ranks sixth and is the highest-positioned Vietnamese battery brand in the supplied study. Its local position is supported by Vingroup resources, domestic commercial-storage projects, off-grid and microgrid applications, and a growing focus on LFP storage.

For a buyer, the important question is how the brand separates vehicle-battery activity from stationary energy-storage products. The supply package should identify the stationary battery model, system capacity, voltage, BMS, enclosure, cooling, installation conditions and local service structure.

Local manufacturing and local communication can be strong advantages for Vietnamese projects. Ask for the actual local production or assembly scope, core component origins, certifications for the exact stationary model and the company responsible for warranty replacement.

7. EVE: cell capability connected to commercial and residential channels

EVE ranks seventh through commercial and residential battery activity delivered by local distributors and system integrators. Its position is useful for buyers that are comparing cell supply, battery-pack supply and complete storage systems from different channel partners.

EVE is primarily encountered as a cell and battery supplier. A battery pack using EVE cells may come from a separate PACK company or system integrator, so the quotation must identify the cell model, PACK company, BMS provider, system integrator and warranty entity.

Key documents include the cell datasheet, battery-pack specification, BMS communication profile, cycle-life test conditions, UN38.3 or other shipping documents, inverter compatibility and Vietnamese service arrangements.

8. Energy Storage Vietnam: local modular-system positioning

Energy Storage Vietnam ranks eighth as a local storage-system brand. The study places it in modular container storage and local off-grid and microgrid projects, where system assembly, local coordination and service access are important.

The supplied study also describes the brand as the first local storage-system brand to obtain TUV certification. That statement should be published only after the certificate holder, certificate number, covered model, standard and validity period have been checked. Certification belongs to a defined product and legal entity, not to an entire brand by default.

For procurement, request the full system diagram, cell source, BMS and PCS models, enclosure rating, fire protection, monitoring, certification package and service address. Local system integration is most valuable when its scope is clear.

9. Great Power: value-oriented cell and battery-pack supply

Great Power ranks ninth and is associated with residential-storage cells and battery packs supplied through traders and inverter manufacturers. Its value proposition is strongest in price-sensitive channels that need a practical LFP battery route and a broad system-partner network.

The procurement decision depends on what the buyer is actually purchasing. A cell shipment, a battery module and a finished inverter-compatible battery cabinet have different technical and commercial responsibilities. The final quotation should show each layer instead of using one brand name for the whole system.

Check the cell model, PACK design, BMS firmware, rated and usable energy, continuous current, communication interface, compatible inverters, packaging and transport documents. These details help installers protect the channel from avoidable compatibility problems.

10. Samsung SDI: high-end project and corporate supply positioning

Samsung SDI ranks tenth in the study. Its Vietnam storage position is concentrated in high-end commercial and residential projects, especially projects connected to the wider Samsung corporate ecosystem. The total volume is smaller than the leading Chinese brands, but the project value and quality expectations are high.

Samsung SDI should be evaluated through the exact battery system, integration partner and project service contract. The brand name alone does not specify the cell chemistry, system voltage, usable energy or inverter compatibility.

Project buyers should request the exact system model, technical documents, certification scope, commissioning process, service territory, replacement strategy and responsibility matrix between the cell supplier, system integrator and local installer.

What this ranking means for Vietnam battery buyers and distributors

1. Start with the supply layer

Ask whether the quotation covers cells, modules, PACKs, a battery cabinet or a complete ESS battery block. Each layer has a different price, warranty and compatibility responsibility.

2. Do not compare cell prices with complete-system prices

A complete battery system includes BMS, enclosure, protection, thermal management, controls, shipping documents, commissioning and after-sales support. The lowest cell price does not create the lowest project cost.

3. Battery capacity works together with system power

The project also needs continuous charge and discharge power, peak current, usable capacity, battery voltage and inverter limits. The battery must be sized together with the critical load and the selected PCS or hybrid inverter.

4. System brands and cell brands serve different procurement tasks

CATL and BYD can be evaluated through cell and system capability. Huawei and Sungrow should be evaluated through integrated system delivery. EVE and Great Power may enter through cells or battery packs. The buyer needs to identify the role before comparing suppliers.

5. Local brands require a clear production and service map

For VinFast Battery and Energy Storage Vietnam, local access can reduce communication and service friction. Buyers should still request the actual local assembly scope, imported component list, certification entity and warranty process.

Cell brands, system brands and ranking boundaries

Industrial cell manufacturing capacity alone cannot establish strong Vietnamese residential or commercial system shipments. A cell company may have large global production while its Vietnamese stationary-storage channel remains small. A system integrator may ship a large battery system while sourcing cells from another manufacturer.

Utility-scale project delivery can move from one year to the next, and local data is more complete for some brands than for others. Use the list to build a shortlist, then verify the exact system, supplier and documents.

Frequently asked questions

Which energy storage battery brand ranked first in Vietnam in 2025?

CATL ranked first in the supplied cross-source assessment, supported by large utility-scale and commercial battery-system shipments. The 25%–30% share shown in the study is an estimated range derived from the study’s evidence set.

Is this a ranking of battery-cell manufacturers?

Research basis and scope

This article is based on CVC Energy’s 2025 Vietnam storage-battery-system shipment study. The study combines third-party market research, public company disclosures, China-to-Vietnam export tracking and Vietnamese channel evidence. The ranking is a cross-source reconstruction of brand shipment positions; the source pack does not provide a single public official table of exact brand shipments.

The calculation uses 2025 annual battery-system shipment capacity with a 60% utility-scale, 25% commercial and industrial, and 15% residential weighting. It excludes standalone cell trading as a separate ranking category. Exact cell models, system configurations, certificates, compatibility and warranty terms must be confirmed for the quotation.
