BYD Blade Battery: what it changes for the parts side — and what stays outside our scope

The Blade Battery is the most-discussed piece of hardware on a BYD, and on the parts side it is mostly discussed the wrong way round. Structurally it is a lithium iron phosphate pack built in a cell-to-pack arrangement, which means the cells go into the pack without the intermediate module layer that earlier designs used. For a buyer, that construction decision does one important thing: it moves the boundary between what the aftermarket can order and what it cannot. Inside the boundary there is one sealed assembly. Outside it there is an ordinary car, with coolant to move, temperatures to measure, brackets to hold things and seals to keep water out. This page is about that outside layer — the parts that remain ordinary purchasable lines — and about saying plainly where the boundary sits. It is an identification page: no repair or removal sequence, no torque figure, no circuit detail and no diagnostic procedure appears on it.

1. What cell-to-pack changes on a parts list

Four consequences follow from the construction, and they all point the same way.

Read together, these say that a workshop's purchasing exposure on a Blade Battery vehicle is concentrated in the layer around the pack, not inside it. That is a narrower list than most buyers expect, and it is also a more number-sensitive one, because the lines that remain are shared with the rest of the range and are not unique to any one model.

There is a second consequence. Because the pack is not an aftermarket service item, the parts that fail, age or get damaged in normal use sit disproportionately on its perimeter: the hardware that moves coolant, the sensors that report temperature, the seals that keep housings dry, and the brackets and covers that hold it all in place.

2. Where the line is drawn

Restraint-system and high-voltage parts are outside the scope of this page.

That sentence does specific work here, so it is worth mapping onto the layers a buyer actually meets:

The first two rows are the ones buyers ask about most and the ones we answer in a single way. The pack body, its modules and the battery management master control belong to the excluded group, as does the high-voltage path between the pack and the drive unit. Nothing on this page describes work on any of them. The third, fourth and fifth rows are what this page exists for.

One more boundary is worth stating, because it is the one that gets confused in practice: a part can sit physically close to the pack and still be an ordinary purchasing line. A coolant pump, a temperature sensor and an O-ring live in the thermal-management and sealing categories regardless of what they are near. Whether the reference you hold falls on the purchasable side is settled per enquiry against the number and the VIN, not by where the part appears to be.

3. The thermal-management layer that is purchasable

This is where our own index is most populated in this area, and it is also where the number density is highest.

In our own data we see five references under the single name Electric Coolant Pump, plus two more under the closely related name Additional Electric Coolant Pump. We see three under Sensor, Coolant Temperature. Our published index carries no fitment column, so none of these numbers can be assigned to a model, a pack size or a model year from the listing alone. That is not a gap we fill by guessing: it is the reason the number plus the VIN is the only workable selector.

The two single-line entries are the ones that cause reorders. 10500252-00 is listed as Sensor O-Ring and 13246638-00 as Sensor Fitting And Protecting Elements, each as its own line. Ordering a temperature sensor by its number therefore does not carry a seal with it unless the number says so. If the job touches both, both numbers belong on the same order, and asking for them together costs nothing extra on your side.

4. Why the VIN comes first for anything in this area

Three things converge here.

The first is specification. Thermal hardware is specified per vehicle, and one pack capacity on one model does not imply the same pump or the same sensor as another capacity on another model. The name is shared; the number is not.

The second is model naming. The Blade Battery is used across the European line-up, and the vehicles marketed in Europe as Dolphin, Atto 3, Seal, Seal U, Sealion 7, Tang and Han sit alongside plug-in hybrid derivatives carrying DM-i suffixes. Two cars can share a showroom, a body shape and a battery technology and still take different thermal-management references.

The third is our own data. There is no fitment column in the published index, so we do not infer application from a model name, a photograph or a description. Application is confirmed per enquiry against the OE number and the VIN.

The practical rule follows: for anything in the thermal-management, sealing or mounting layer, send the VIN with the enquiry rather than after it. An enquiry with a VIN and a part number is answered on the first pass; one with a description and a model name generates a round of questions.

5. What to send, and what happens next

Four items settle almost every enquiry in this area. The VIN, which fixes the vehicle and its powertrain. The OE number read off the old part, including the -00 suffix, which is part of the identifier in this format. A photograph of the label and of the part in position, because labels in this area get unreadable. And whether the seal, O-ring or protective element is wanted at the same time, so both numbers can be confirmed together.

We confirm, part number by part number, whether we can supply it. Minimum order value is €50 per shipment; guide prices are shown on the parts pages, and trade and volume pricing on request. Typical dispatch time is confirmed on the quotation; transit depends on the shipping method you choose. If the line you need does not appear in the published index, send us the part number or a photo of the label, and we will check whether we can source it. Start from the BYD-compatible parts — OE reference index, browse the engine cooling category or the electrics and sensors category, or use the enquiry page.

Short answers

Is the Blade Battery itself an orderable part from GNSGO? No. The pack body, its modules and the battery management master control, and the high-voltage path between the pack and the drive unit, are outside the scope of this page. What remains purchasable is the layer around them — thermal management, sensing, sealing and mounting.

What can I still order on a Blade Battery car? The vehicle-side cooling and sensing hardware and its associated sealing and mounting parts. Our index holds five Electric Coolant Pump references, two Additional Electric Coolant Pump references and three Sensor, Coolant Temperature references, all quoted by number.

Do I need the VIN, or is the model name enough? The VIN. Our published index carries no fitment column, and the same model name spans more than one specification, so the number plus the VIN is the only reliable selector.

Does a coolant temperature sensor come with its O-ring? Treat it as a separate line. Sensor O-Ring 10500252-00 and Sensor Fitting And Protecting Elements 13246638-00 are listed independently in our index.

Will you tell me how to work on the pack? No. This page covers parts identification and purchasing only. Work on high-voltage systems belongs with technicians qualified for it.

Why does one part name carry five numbers in your index? Because our index records references, not interchange. Five Electric Coolant Pump references means five listed lines; we do not assume they substitute for one another.

Where this comes from.

The references and group counts quoted above are taken from GNSGO's own parts index for BYD vehicles — the same list at BYD-compatible parts — OE reference index. Application is confirmed per enquiry against the OE number and the VIN; the published index does not carry model-year fitment, so we do not infer it here. Model names follow the export designations listed for this project, and we do not assert naming relationships beyond them. We have not drawn on BYD's copyrighted workshop documentation, and we do not reproduce any manual or wiring-diagram pages. Where our own data does not carry an answer, we say so rather than filling the gap with a plausible one.

This page is general information only. It is not a repair instruction, not a diagnosis of a particular vehicle, and not a substitute for professional advice. Restraint-system and high-voltage parts are outside the scope of this page. Work on high-voltage systems, restraint systems and structural repairs belongs with technicians qualified for it. Confirm the application against the VIN before ordering. Have any work carried out by a suitably qualified workshop.
