This independent guide outlines the considerations between genuine and aftermarket parts for the BYD DOLPHIN pure electric hatchback (BEV). It is important to note that trim names, specifications and prices reflect a compiled dataset (October 2026) and that BYD Automotive Australia may update variants, so every figure must be confirmed with an authorised BYD dealer or the official BYD Australia website.

The BYD DOLPHIN is a front-wheel drive electric vehicle featuring a BYD Blade Battery (44.9 kWh on the Essential, 60.48 kWh on the Premium). It contains no petrol engine, exhaust, or engine oil, and has a kerb weight of 1,506 kg for the Essential and 1,658 kg for the Premium. As such, the parts discussed pertain strictly to the electric powertrain, high-voltage systems, and consumable items like tyres, brakes, and cabin filters. Any dimensions, such as the 4,290 mm length, 1,770 mm width, 1,570 mm height, and 2,700 mm wheelbase, must be factored in when considering aftermarket external accessories.

High-Voltage Components and Powertrain
The BYD DOLPHIN utilises an advanced electric drivetrain, with a permanent magnet synchronous motor delivering a maximum power output of 70 kW (180 Nm maximum torque) for the Essential and 150 kW (310 Nm maximum torque) for the Premium. Work involving the high-voltage system, including the DC charging port (CCS 2) and AC charging port (Type 2), must be done by an authorised BYD dealer or qualified technician. High-voltage orange cables must not be touched or opened by owners. Genuine replacement parts for the traction battery and motor are sourced directly through the official service network. The New Vehicle Warranty covers the power battery and drive unit for 8 years or 160,000 km, whichever occurs first, with a guarantee of at least 70% battery capacity retention.
Any failure caused by the use of non-BYD genuine or non-recommended parts causing damage is not covered under the manufacturer warranty. Owners must also consider that failure to follow correct charging procedures can void coverage. Always refer to the official owner’s manual before considering any modifications or when maintaining the battery system.
Tyres and Wheels
The Essential model is equipped with 195/60 R16 tyres on alloy wheels, while the Premium features 205/50 R17 tyres. When considering a BYD Dolphin tyre replacement or exploring options like Michelin or Linglong tyres, owners must ensure replacements match the official load and speed ratings. Tyres are not covered by the BYD warranty; tyre manufacturers’ warranties apply. Maintaining correct tyre pressures is monitored via the vehicle’s tyre pressure monitoring system.
Any alternative wheels must be compatible with the front MacPherson strut and rear torsion beam (Essential) or multi-link (Premium) suspension setups. To ensure compliance with the 1,916 kg (Essential) or 2,068 kg (Premium) gross vehicle mass ratings, confirm with BYD Automotive Australia or an aligned tyre specialist before fitting non-standard sizes.
Brakes and Fluid
The braking system consists of ventilated front discs and rear discs, supplemented by regenerative braking. For those evaluating BYD Dolphin brake pad life or conducting a disc wear inspection, all replacement components must meet strict safety standards. Replacing brake fluid is a specified maintenance item on the official service record for the EV series. Servicing the electronic parking brake, ABS, and auto hold functions must be done by an authorised BYD dealer or qualified technician.
Non-genuine brake components may alter the performance of advanced safety systems such as automatic emergency braking, predictive collision warning, and rear or front cross traffic alert and brake. For any brake servicing, always consult an authorised BYD dealer to maintain system integrity and ensure the safety features function correctly.
Interior Accessories and Electronics
Interior modifications and electronic add-ons must not interfere with the vehicle’s 12V auxiliary system (lead acid starting battery covered for 12 months or 20,000 km), the 5-inch digital instrument panel, or the 12.8-inch intelligent rotating touchscreen. If a driver is researching online discussions about a potential overheat issue with the BYD Dolphin wireless phone charging pad (noting this pad is equipped on the Premium variant), the condition should be assessed using official diagnostic procedures by a qualified professional.
Anyone investigating a genuine dash cam hardwire installation for the BYD Dolphin or similar electronic integration must ensure it does not jeopardise the vehicle’s electrical warranty. Unauthorised modifications or third-party conversions, including software alterations, are explicitly excluded from warranty coverage. Always ensure that aftermarket interior additions remain subject to manufacturer specifications.
Exterior Parts and Wipers
Exterior replacements such as glass, panels, and lighting must accommodate the vehicle’s network of sensors and cameras, including the 360-degree view monitor, blind spot detection, and front parking sensors (2 zones) and rear (3 zones). When sourcing the correct size for BYD Dolphin replacement windscreen wiper blades, exact measurements are required to maintain clear visibility. Wiper blades are considered a consumable item and are subject to replacement charges.
For bodywork repairs or replacing external trims in colours like Ski White (standard), Harbour Grey, or Atlantis Grey, consult an authorised BYD dealer to ensure paint matches the factory finish. Paint application defects are covered for 1 year under the warranty, provided the vehicle has not been subjected to unauthorised alterations.
Servicing and Consumables
The official maintenance schedule requires services at 20,000 km / 12 months, 40,000 km / 24 months, 60,000 km / 36 months, 80,000 km / 48 months, 100,000 km / 60 months and 120,000 km / 72 months (whichever comes first). Routine items include checking the PM2.5 air filter and replacing the e-motor controller coolant. When selecting aftermarket cabin filters, they must fit the dimensions required by the vehicle’s automatic air-conditioning and heat pump systems. To avoid warranty disputes, owners should ensure any aftermarket parts meet or exceed the quality of genuine BYD components.
Frequently Asked Questions
Can I install an aftermarket battery in the BYD DOLPHIN?
The 44.9 kWh and 60.48 kWh BYD Blade Batteries are proprietary high-voltage components. Any replacement must be done by an authorised BYD dealer or qualified technician, and high-voltage orange cables must not be touched or opened by owners.
Are genuine parts required for standard servicing?
While independent mechanics can perform maintenance, using non-BYD genuine or non-recommended parts that cause damage will void the relevant sections of the 6-year / 150,000 km vehicle warranty. Genuine spare parts bought and installed by an authorised BYD Retailer include a 12-month warranty.
Can I fit aftermarket wheels to the BYD DOLPHIN?
Aftermarket wheels can be fitted provided they meet the correct specifications for the 16-inch or 17-inch factory sizing. All modifications remain subject to manufacturer specifications to ensure compatibility with the electronic stability control and traction control systems.
Where can I find part numbers for genuine replacement parts?
BYD Australia does not publish a public online parts catalog with OEM part numbers. To source exact parts, refer to the official owner’s manual or supply your vehicle identification number (VIN) to an official service centre.
