December 19, 2019, “repairer new forces” Xiaopeng Xiaopeng car brand’s an electric car tail appears G3 dramatic fire burning, the user first alarm, and put out the fire. There is a view that part Xiaopeng G3 spontaneous combustion fire accident caused Xiaopeng manufacturers timely accident investigation report released by the detection of the accident from the combustion lead to an external fire source, not caused by spontaneous combustion vehicles.
As can be seen in the photograph of the vehicle according to extinguish, this power Xiaopeng G3 bottom cell assembly intact, vehicle trunk, and tail and serious internal injury.
1, G3 Xiaopeng Three old core technical analysis:
After removal of the shield graph
, the older technology Xiaopeng G3 Engine Compartment close-up details of the state.
Xiaopeng G3 is distributed using an electric drive system, cooling by a circulation line for the group driving motor, motor driving control assembly, and the DCDC charger “2 in 1” and a high pressure control assembly power distribution box, the control system and to provide cooling of high-voltage servo (red arrow for the coolant flow direction); a group circulation line-powered and low temperature heat cell assembly preheated servo; 1 cockpit air-conditioning circulation line group providing a servo system heating.
It is noteworthy that while older G3 Xiaopeng has two battery suppliers adapter, load 47.1 kWh version, NEDC life of 351 kilometers, battery power supply cargo operators for the BAK. 47.6 kWh be loaded version, the NEDC life of 365 km, battery suppliers linkage wing, wing joint is contracted while the Panasonic Wuxi plant line 18650 which supply three yuan 18650 lithium and substantially Tesla consistent.
2, the core technology of the new G3 Xiaopeng analysis:
The new G3 Xiaopeng no changes in the powertrain, still equipped with a power of 145 kW permanent magnet synchronous motor, the maximum torque of 300 Nm, but since the new G3 Xiaopeng increase in battery capacity, improve body weight results in accelerated old one hundred kilometers in 8.4 secondsOn the basis fell 0.1 to 0.2 seconds.
compared to the old section of the new G3 models Xiaopeng biggest gap is to change the battery capacity and suppliers. In order to load a larger capacity battery, the new G3 Xiaopeng compared to older models wheelbase of 15 mm, the current wheelbase is 2625mm. The new G3 Xiaopeng and older models, like the use of two battery suppliers supply mode, pure electric 400 km standard version equipped with 50.5 kWh battery life, the author of suppliers currently unknown, according to I guess a large probability of linkage Tianyi 18650 Matsushita three yuan cylindrical lithium battery. When the electric-life 520 km 66.5 kWh mounted version, supplier Ningde age, but also using the latest age Ningde side shell 811 formulation three yuan lithium batteries, battery energy density up to 180 W / kg.
into the 2019, 18650-type battery system using S Tesla electric vehicles, several cases still continued burning accident.
The new G3 Xiaopeng adapted power battery shell also with square cells and batteries 18650 Ningde provided mainly age. Xiaopeng is currently no way of knowing whether the new G3 battery power when using two matching different battery thermal management system, whether it is common or different battery thermal management system for the “repairer new forces” for the car Xiaopeng It is a huge challenge.
I have something to say:
However Xiaopeng G3 For more than a year, in line with a car has introduced an integrated two different specifications batteries, four different battery module Supply technology roadmap to provide power battery system, unlike other “repairer new forces” and “traditional depot.”
2018 –2019 years Wei, the Weimaraner, Xiaopeng, ideal, etc. “repairer new forces” will have its first model on the market. Almost no one thought about a brand is not a problem, even EX8 Wei to take place in 2 months in a row four burned accident and recall. The Weimaraner EX5 listed more than a year, there has been shortened mileage, body welding and control system failure.

2019 startingSales caused by the fall, as well as weakness in the foreseeable continued in 2020 sales, leading to “traditional depot” reduce unnecessary overhead through many aspects. For Split “repairer new forces” who market share, far better than relying on financing “blood transfusion” to live is important.
The following is a statement released by car Xiaopeng:
The first time the car Xiaopeng Xiaopeng announced G3 combustion cause of the accident and quickly respond to the public attitude, worthy of recognition.
