New Energy Intelligence Analysis Net Beijing North Fang Huapeng BYD Auto Group, Department for BYD EV and PHEV vehicle accidents due to human impact, expand involving body welding, electric drive system and battery severe service process Quan Jilu.
This paper records this is BYD yuan EV360 models, and the configuration can be very rare, more presence in Beijing, as this table to match the car accident 160 kilowatts permanent magnet synchronous motor with a top element EV360. The picture shows the earlier recorded membered EV360 disassembled state after the collision portion of the close-up subsystem.
top version membered EV360 electric vehicle LWH 4100 (4360) x1785x1690mm, wheelbase is 2535mm; can be attributed to the compact car. After original installation of the body length of 4100mm in a set of plug-in components of the spare tire, reach 4360mm. The picture shows a collision in this dismantling membered EV360 “4in1” electric drive control system, the part of the additional subsystems, close-up repair.
After several days before repairs can be found, repair the car before the engine compartment basically come to an end, severely damaged the whole box-type sub-frame has been replaced as a whole is completed, fracture electric drive assembly mounting (aluminum + rubber) was replaced with new parts.
In addition, since the table element EV360 is a front collision, the front portion of the radiator frame power completely damaged compartment, the front portion of the vehicle body side member and the bracket completely crash box crush safety played a role in protection, therefore, the maintenance element EV360 front portion of the engine compartment to replace the whole or part prior to welding the crash box and the side frame, is now installed.
Preparation into the next maintenance phase, will enter the electronic control, the motor mounting step detection systems and other accessories, the original is first detected before collision electric control, motor system is damaged then assembled according to the actual situation.
The author further repair shop see table 1 collidesAccident, and adaptation “e platform” technology solutions yuan of new EV models. Since the front of the car collision accident, so the front bumper and the left front fender panel detached. The picture shows that engine compartment cloth with the “3 in 1” electric drive system, “3 1” close-up high-voltage power system assembly.
introduced a “4 in 1” level EV drive engineering models 2018, 2019 are a “3 in 1″ single drive control assembly. ” e platform “technology models instead. Such as Yuan Yuan EV360- EV535; EV450- Qin Qin Pro EV500 similar evolution. However, no matter which technology platform model, as long as the collision occurred, should be shut down high-voltage systems, “zero voltage” safe operation (maintenance).
I have something to say:
In winter, the snow-covered road surface friction coefficient decreases, resulting in loss of control caused by a vehicle collision occurred frequently. Even freezing rain caused the area south of the Yangtze River is also difficult to guard against accidents.
due to low temperatures, a sheet metal painting class maintenance efficiency than the Spring and Autumn Period low, coupled with the 4S shop or an authorized service station windshield of different models, bumpers, doors, air bags and other accessories kit storage strategy different, often lead to the maintenance cycle for up to two weeks or even a month.
Note that, the EV PHEV models and models relative specificity of traditional fuel vehicles (high voltage), the electric drive system, the control system is exclusively produced by the manufacturer or authorized supply. This leads to uniqueness and quality of repair parts procurement channels.
for electric vehicles, insist on insurance in the 4S shop or an authorized service station and relates to an electric drive and battery power level maintenance is to ensure the maintenance of quality and original replacement parts fundamental guarantee. About the maintenance situation yuan EV360, we will continue to monitor reports, so that consumers can clearly understand the situation after the maintenance vehicle accident.
