BYD's technology is said to be strong, in the end strong in what aspects?

With the rise of independent brands, those first-tier brands have also pulled together some fans, such as Chery's "new Qi army" and BYD's "Di powder", Chery's engine technology needless to say, if you are interested, we can open a separate topic to talk about how Chery's fans are formed. Today, we are mainly talking about BYD's "Di fans", what technology do they see in BYD? And what's so great about BYD?

Similar to the concept of platforms in the traditional automotive industry chain, BYD's "e-platform" is a highly integrated and standardized modular platform for electric drives. To put it simply, it is a one-stop package solution for EV battery technology. ePlatform includes the five most critical technologies for an EV, namely:

The ePlatform is a one-stop package solution for EV battery technology. They are:

1, "drive three in one": contains the motor, motor controller, and reducer. It is equivalent to the engine and transmission in a traditional gasoline car.

2. "High-voltage 3-in-1": It contains DC-DC DC converter, OBC on-board charger, and PDU high-voltage distribution box. It is equivalent to the "substation" and "dispatching station" responsible for the deployment of high-voltage electricity in the car.

3, high-performance power batteries: from a block of "core" composed of weight, size standardization of the battery "module", and then a "module" combined together. Equipped with a battery management system, intelligent temperature control system, fire and waterproof anti-extrusion shell "pack" into, which is often referred to as the "battery pack".

4, PCB low-voltage controller: responsible for controlling the car's low-voltage system functions (such as door locks, windows, instrumentation, etc.) of an integrated circuit board, equivalent to the control of a variety of automotive functions of the "headquarters".

5. DiLink Intelligent Internet Connection System: This includes a rotatable intelligent display and the intelligent Internet connection application ecology that unfolds around it. It is the window from the "electric car era" to the "smart car era".

The electric motor is positioned between the engine and transmission to provide peak torque, a structure favored by many brands because it allows upgrading from a traditional fuel vehicle to a hybrid without costing a fortune in research. But the shortcomings are also very obvious, between the engine and transmission must have enough space to install the motor, the more abundant space can be loaded with the motor is bigger, hybrid effect is naturally better, and vice ...... versa small space is very chicken.

From the total torque output, the disadvantage is that the motor is behind the transmission, which means that the torque output range is relatively single, can not change the torque through the transmission, and the motor in the vehicle at high speeds, the efficiency will be reduced quite a bit, which means that when running at high speeds the efficiency of the P3 is not so optimistic. As for the P4, it is more powerful power explosion, but also achieved the "BYD sports car - Tang" this kind of statement.
