Smartphones have become our standard, and we are now accustomed to receiving system updates or upgrade notifications from smartphone manufacturers, upgrading new versions, updating systems, fixing bugs, adding new features, etc. I believe that many people, like the old driver, have an inexplicable "excitement" every time they receive a notification from the mobile phone update system.
In fact, not only is the smartphone able to bring new features through the OTA update system, but now even the car can achieve such a function. Of course, the best in this area, and even the only outstanding one is the famous Tesla.
In today's automotive field, Tesla can be said to be the most technologically advanced manufacturer. Tesla not only shoulders the banner of the number one electric car manufacturer, but also constantly uses various highly technological features since its inception. The function continues to challenge the “bottom line†of the traditional automotive industry.
Among Tesla's many features, the way the car system supports OTA upgrade is definitely the most eye-catching feature. As long as the system is upgraded online by means of a smartphone, Tesla can bring more consumers. Many new features, from auto-assisted driving to speed-up, and even small features that are less interesting, can be done by updating the system.
In our traditional impression, it seems that the speed of a car has been determined at the factory, what engine displacement, torque and horsepower, etc., these are parameters that cannot be changed after leaving the factory. But Tesla's electric car can continuously improve its speed performance through system upgrades, which once again challenges our inherent impression of the car.
So now let's take a look at why Tesla electric cars can create new accelerated records and performances by simply updating the system.
Repeatedly updating the system to increase the top speed
If you keep an eye on our channel's automotive technology news, you will always see news about a certain model of Tesla car to increase the top speed through system updates. As the current "power value" and "speed representative" in the field of electric vehicles, Tesla has repeatedly used this seemingly relaxed and happy way to bring unlimited passion to users.
In December 2014, Tesla's two flagship sedan Model S 85D and P85D ushered in a firmware upgrade that increased the maximum speed to 250 km/h. Previously, the electronic speed limit of the P85D and 85D was 210 km/h. After the firmware upgrade, not only will the speed be up to 250 kilometers per hour, but the torque can be adjusted.
Just two months later, in February 2015, Tesla's Model S P85D once again ushered in an OTA upgrade, and this time Tesla upgraded the acceleration time of 100 kilometers by 0.1 seconds.
The acceleration of the Model S P85D continues to increase with the OTA firmware upgrade, and the 100 km acceleration time is further reduced by 0.1 seconds. Previously, the Model S P85D had a 100-second acceleration time of 3.2 seconds and a firmware upgrade of just 3.1 seconds. Don't look at this upgrade only for 0.1 seconds, but still shows the power of Tesla firmware upgrade.
In November 2016, after Tesla launched its flagship Model S P100D top-of-the-line model, it launched the “Crazy Acceleration Mode†for the first time, and this model can also accelerate the 100 km of the Model S P100D by updating the system now. The time has increased by 0.1 second, from the original 2.5 seconds to 2.4 seconds.
Also after only two months, Tesla was not satisfied with the 2.4 second 100 km acceleration time of the Model S P100D. CEO Elon Musk said on his official social media: "From the previous test data, Tesla's 100km acceleration time is 2.34 seconds, which is achievable."
Speed ​​up the system
Traditional internal combustion vehicles want to increase the acceleration time or top speed of 100 kilometers, which is not impossible, but it needs to be completed by retrofitting large projects such as electronic control unit system. It is not only costly, but also time-consuming and laborious. It is definitely not worth the candle, only professional car modification or enthusiasts can complete.
And why does Tesla only accomplish the goal that traditional cars can do so by updating the system? In fact, Tesla is to maximize the advantages of electric vehicles themselves, and optimize the inverter algorithm by upgrading the system to improve the performance of the top speed.
Tesla uses system firmware to control the torque of the motor and the energy transfer process of the battery pack through a system-wide firmware update coupled with hardware such as rotating inverters, digital signal processing systems, and charging systems. It is the energy control system of the entire car body.
Through a high-performance digital signal processor, Tesla can convert the requirements of braking, braking, acceleration and deceleration of the car into digital signals, thereby controlling the rotating inverter to convert the direct current and alternating current of the battery pack to drive the three-phase induction motor. Provide the corresponding car power. And that's why Tesla can increase the speed of the car only by updating the system.
In addition to upgrading the system, there are other speed-up methods.
For an electric car like Tesla, in addition to the unconventional way of updating the system, there are many conventional ways to increase the speed of the electric car, and Tesla has not let go of these methods.
For example, in the "crazy acceleration" mode that everyone is familiar with, the most direct way to get the motor to provide higher power and torque output is to increase the current. However, boosting the current is equivalent to overclocking the CPU processor, which has the direct consequence of temperature rise, and this puts higher demands on the safety of the battery components. And Tesla has replaced the original standard fuse with a series of technologies, such as "smart fuses", so that the monitoring accuracy of the current is up to millisecond, and the improvement of the battery package uses the inconel instead of steel for the main battery contactor material. Redesigned lithium battery circuits and smart fuses to ensure the safety of the battery, and if it is extended, it is another system, and everyone knows more about it for the time being.
Simply put, in addition to updating the system, improving battery technology, improving battery energy density and safety, it is also the key to Tesla's continuous improvement in speed.
However, it should be noted that too much pursuit of high speed will bring huge consumption of unconventional speed to electric vehicle components, so it is better to use this crazy acceleration mode.
Toggle switches
Toggle switches, also called On Off Toggle Switches, is often used as the switching device of the equipment stalls. Meanwhile, we are also offer our customers Key Switches, Metal Switches, Automotive Switches, Push Button Switches, etc.
The Electrical Toggle Switches is a manually controlled Toggle Switches similar to the dial switch. Most of this Latching Toggle Switches are widely used in on-off control of AC and DC power circuits, and are less commonly used in circuits of several kilohertz or up to 1 megahertz. Let's take a look at the following.
1. Splash-proof knob button switch
The panel is installed with a splash-proof `O` ring seal, and the knob is a ball. It is a splash-proof ball button knob switch. Its terminals are in a straight line and the bottom of the terminals is sealed with epoxy resin. Strong corrosion resistance, suitable for automotive parts
2. Vertical Mount Right Angle Toggle Switch
The vertical mounting of the terminals and the terminal pins are right-angled, so it is a vertically mounted right-angled toggle switch. Its contacts are gold-plated and highly reliable. Mostly used in anti-theft devices, alert system.
3. Bipolar single toggle switch
At the same time, the switch breaks the phase line and the N line and controls one branch. Therefore, it is a bipolar single toggle switches. The contacts are in 3PDT form and are used for multimedia speakers and stereos.
4. Standard surface mount unthreaded toggle switches
The terminal adopts the standard mounting mode. Its sleeve has no thread. It is called a standard surface mount screw-less switch. The contacts are SPDT and its electrical life is as high as 55,000. Used for medical equipment
5. Horizontally mounted right-angle toggle switch
Compared to the vertical switch, it only changes direction to horizontal, so it is horizontally mounted right-angle toggle switch. The contacts are double-pole double-throw and the bottom of the terminal is Epoxy Seal. Mostly used for computer peripherals.
