Symptom Finder: Known Weak Points
| What you see or hear | Check first |
|---|---|
| Range noticeably shorter than when the car was new | Battery health first. The pack changed three times across the car's life, so confirm which pack is fitted and order any pack-side part by OE number. |
| Car will not take a fast charge or shows a charging warning | The charging socket, its seals and wiring. On the updated car the fast socket is at the front and the slow socket at the rear right, so order by position. |
| Knocking from the front over bumps | The front strut top mounts, springs and struts. Many of these cars worked in fleets, so inspect them on condition rather than mileage. |
| Clunk when pulling away or lifting off | The drive-unit mounts. Motor output changed from 160 kW to 100 kW in 2019, so match the replacement mount by OE number. |
| Rear brake grinding or a parking brake warning | The rear discs and the electronic parking brake caliper. Regenerative braking leaves the discs lightly used, so they can corrode before they wear thin. |
| Weak heating or cooling, or a noisy blower | The blower motor, evaporator and heater core. Trace the fault to its part, then order by the OE number on the old unit. |
| A replacement headlight or bumper does not line up | The car's body version. The November 2019 update changed the front end, headlights and tail lights, so match parts to the body on the car. |

About BYD Qin EV Parts
The BYD Qin EV is the first pure-electric Qin, a five-seat compact saloon launched in late March 2016 as the Qin EV300. It uses the original Qin's 2,670 mm wheelbase. It drives the front wheels through a single permanent-magnet motor, rated 160 kW on the early cars and 100 kW from the November 2019 update onwards. There is no engine, so there is no oil, exhaust or fuel system to service. The parts it needs are suspension, brakes, cooling and climate hardware, the battery pack and the charging parts. Over its life the car changed battery chemistry twice and was restyled once. A part that fits one Qin EV may not fit another, even though the name stayed the same. Every part on this page is listed by its OE number, and matching the number on the old part is the surest way to confirm a fit.
What to know before buying BYD Qin EV parts
Start by making sure the car is a Qin EV and not a Qin Pro EV or Qin PLUS EV. Those later cars use a longer 2,718 mm wheelbase against the Qin EV's 2,670 mm, so suspension, subframe, floor and body parts listed for them will not fit here. A tape measure between the wheel centres settles it quickly.
Next, work out which body the car has. Qin EVs built before the November 2019 update keep the original Qin front end and measure 4,740 mm long and 1,490 mm high. The updated car has the dragon-face front, headlights with a row of five LED units, revised tail lights, and a body 4,675 mm long and 1,500 mm high. Width stayed at 1,770 mm and the wheelbase did not change. Front bumpers, grilles, headlights and tail lights from one body do not suit the other, so check the front of the car before ordering anything for the ends.
The battery is where most wrong orders happen. The 2016 EV300 carried a pack of about 48 kWh. In 2018 the EV450 moved to ternary lithium cells at 140.97 Wh/kg. The November 2019 car used a 53.1 kWh ternary pack at 160 Wh/kg, and the 2021 ride-hailing edition returned to lithium iron phosphate with 53.56 kWh. Two packs with similar capacity can still differ in cells, mass, mounting and cooling, so do not order pack, tray or cooling parts by the kWh figure. Match them by OE number, and read the build date on the identification plate if the old part is missing.
A few things vary from car to car. Motor output fell from 160 kW to 100 kW with the 2019 update, so the motor, drive-unit mounts and related high-voltage parts must be matched by OE number. Tyres of 205/50 R17 were fitted to the EV450 and the 2019 car, and 205/55 R16 also appears on early cars, so read the size on the sidewall before ordering tyres or wheels. On the 2019 car the fast-charging socket sits at the front and the slow-charging socket at the rear right, so order charging parts by position as well as by number.
Some parts are shared with the BYD e5 and the petrol and hybrid Qin models, but many are not. Where a listing names several models, confirm the fit by the OE number on the old part rather than by the model name.
Before You Order: 7 Checks
- Measure the wheelbase if you are unsure of the model: 2,670 mm is the Qin EV, 2,718 mm is a Qin Pro EV or Qin PLUS EV. Order from the listings for your car.
- Match the OE number on the part you are replacing to the OE number on the listing. A matching number is the surest check that a part fits.
- Look at the front of the car before ordering bumpers or lights: the dragon-face front with five-LED headlights marks a car from the November 2019 update onwards.
- Check the build date on the identification plate before ordering battery, cooling or drive-unit parts, since the pack changed in 2018, 2019 and 2021.
- Read the tyre size on the sidewall before ordering tyres or wheels, since both 205/50 R17 and 205/55 R16 appear on the car.
- Order painted panels by the colour code on the car rather than by colour name.
- Order charging sockets and seals by position as well as by OE number, since the fast and slow sockets sit at opposite ends of the updated car.
Generations and Facelifts
The Qin name began with a plug-in hybrid saloon. The Qin EV300, launched in late March 2016, was its first pure-electric version. It used the same 4,740 mm body and 2,670 mm wheelbase, with a single front motor of 160 kW and 310 Nm, a pack of about 48 kWh and a quoted range of 300 km. The battery sat lower in the car than on the hybrid, and boot space grew to 450 litres.
In 2018 the EV450 replaced it. The body stayed the same, but the car changed to a ternary lithium pack at 140.97 Wh/kg, giving an NEDC range of 400 km with the same 160 kW motor. That was the first chemistry change, and it split battery-side parts from the EV300.
On 5 November 2019 BYD launched the all-new Qin EV. This was a facelift of the same car and not a new platform. It gained the dragon-face front end, new LED headlights and revised tail lights, and it shortened to 4,675 mm while the height rose to 1,500 mm. Under the floor sat a 53.1 kWh ternary pack at 160 Wh/kg, and the motor dropped to 100 kW and 180 Nm, with a range of 421 km. For parts, the front and rear lighting, bumpers and drive unit all changed at this point.
The 2021 ride-hailing edition kept the updated body and the 100 kW motor but returned to lithium iron phosphate with a 53.56 kWh pack and an NEDC range of 450 km. That was the second chemistry change. The Qin Pro EV and Qin PLUS EV are separate cars on a longer 2,718 mm wheelbase. Before ordering body, lighting, battery or drive parts, read the build date on the identification plate.
BYD Qin EV Parts: Frequently Asked Questions
How do I make sure a part fits my BYD Qin EV?
Match the OE number. Every part on this site is listed under the OE number printed on the original part, and if the number on the part you are replacing matches the listing, the part fits. That matters on the Qin EV because the name stayed the same while the body, battery and motor changed across its life. If the old part is missing or its number cannot be read, send us a photo through the quote form and we will reply within 24 hours, usually sooner.
Is the Qin EV the same car as the Qin Pro EV or Qin PLUS EV?
No. The Qin EV is the first pure-electric Qin, launched in 2016 on the original Qin's 2,670 mm wheelbase. The Qin Pro EV and Qin PLUS EV are separate cars on a longer 2,718 mm wheelbase, so their suspension, subframe, floor and body parts do not fit here. Measure between the front and rear wheel centres if you are unsure which car you have, then confirm each part by the OE number on the old one.
How can I tell an early Qin EV from the 2019 update?
Look at the front. Cars from the update launched on 5 November 2019 have the dragon-face front end, headlights with a row of five LED units and revised tail lights. The early cars keep the original Qin front. The body also changed length, from 4,740 mm to 4,675 mm, and height rose from 1,490 mm to 1,500 mm. Bumpers, grilles and lights do not cross between the two, so check the body before ordering and match each part by OE number.
Which battery does my Qin EV have?
It depends on when the car was built. The 2016 EV300 used a pack of about 48 kWh. The 2018 EV450 moved to ternary lithium cells at 140.97 Wh/kg. The November 2019 car carried a 53.1 kWh ternary pack, and the 2021 ride-hailing edition returned to lithium iron phosphate at 53.56 kWh. Read the build date on the identification plate, and order any part that touches the pack by the OE number on the old part.
Why can I not order battery parts by capacity?
Because two packs with a similar figure can be built very differently. The 2019 car's 53.1 kWh pack and the 2021 ride-hailing edition's 53.56 kWh pack are close in capacity but use different cell chemistry, and chemistry affects the cells, the pack mass, the mounting and the cooling. A tray, bracket or cooling part made for one pack may not suit the other. Match every pack, tray, mount and cooling part by OE number, using the build date on the plate as a guide.
What changed with the November 2019 update?
BYD launched the all-new Qin EV on 5 November 2019. It kept the 2,670 mm wheelbase and 1,770 mm width but gained the dragon-face front, new LED headlights and revised tail lights, and the body shortened to 4,675 mm. The pack became a 53.1 kWh ternary unit, and the motor changed to 100 kW and 180 Nm with a range of 421 km. For parts, lighting, bumpers, battery and drive unit all changed, so check the build date on the plate before ordering.
What is the Qin EV ride-hailing edition?
It is a 2021 version of the updated Qin EV aimed at taxi and ride-hailing fleets. It uses the 4,675 mm dragon-face body, a 100 kW motor with 180 Nm, and a 53.56 kWh lithium iron phosphate pack with an NEDC range of 450 km. Body panels and lights follow the 2019 car, but the battery chemistry differs, so pack-side parts need care. Match those parts by the OE number on the old part, and check suspension wear on condition, since fleet cars cover heavy mileage.
What motor does the Qin EV use?
Every Qin EV drives the front wheels through a single permanent-magnet synchronous motor, and there is no four-wheel-drive version. The EV300 and EV450 are rated at 160 kW and 310 Nm. From the November 2019 update the motor is rated at 100 kW and 180 Nm, and the ride-hailing edition uses the same output. Motors, drive-unit mounts and driveshafts may differ between the two outputs, so order them by the OE number on the part you are replacing.
What tyre sizes does the Qin EV use?
The EV450 and the November 2019 car were fitted with 205/50 R17 tyres, and 205/55 R16 also appears on early cars. Wheel size can vary between trims, so the model name alone does not tell you what is fitted. Read the size on the sidewall of the tyres already on the car before ordering tyres or wheels. For brake and hub parts, match the replacement by the OE number on the old part rather than by wheel size.
What brakes and suspension does the Qin EV have?
The car uses disc brakes at all four corners with an electronic parking brake. The front suspension is MacPherson strut and the rear is a torsion beam, with electric power steering. Regenerative braking through the motor does much of the slowing, so the rear discs can corrode from light use before they wear thin. Inspect them on condition rather than by mileage, and order discs, pads and calipers by the OE number on the parts fitted.
Does the Qin EV need regular servicing parts?
It has no engine, so there is no engine oil, oil filter or exhaust to replace. Servicing centres on the brakes, tyres, suspension, cabin filter, coolant and climate system, along with the charging hardware. On the updated car the fast-charging socket sits at the front and the slow-charging socket at the rear right, and both take wear from daily use. Check the seals and pins at each socket, and order replacements by position and by the OE number on the old part.
Will BYD e5 or petrol Qin parts fit the Qin EV?
Some will, and many will not. The Qin EV shares its body with the original Qin range, and some running gear is common to other BYD models of the same years, including the e5. Battery, motor and body parts changed several times across the Qin EV's life, though, so a part listed for a related car is not automatically correct. Confirm every cross-listed part by the OE number on the old part, and read the build date on the plate for battery or body parts.
