DEV1 TMS and Temperature Sensors
With the DEV1 being so 🔥🔥🔥, we had to 🧊🧊🧊 it down! In comes TMS to the rescue.
Original Unique Work
A Thermal Management System (TMS) is an essential part of many modern devices from computers to electric cars. It is responsible for keeping electronic components and batteries at a safe operating temperature, which helps to prevent damage and increase their lifespan.
One of the most common TMS’s is a cooling system, which uses a combination of fans and heat sinks to dissipate heat. Heat sinks are usually made of aluminum or copper and are designed to have a large surface area to increase the amount of heat that can be transferred. Fans then blow air across the heat sink to carry the heat away.
Another type of thermal management system is a liquid cooling system. This is often used in high-performance computers or servers, where air cooling may not be sufficient. In a liquid cooling system, a liquid coolant is circulated through tubes that run through the components, absorbing heat as it goes. The heated coolant is then transferred to a radiator where it is cooled down by fans, before being circulated back through the system.
Thermal management systems are also important in electric vehicles. The batteries and inverters in these vehicles generate a lot of heat, which can affect their performance and lifespan. To prevent this, thermal management systems are used to cool the batteries and keep them at a safe operating temperature. This can be achieved through a combination of air and liquid cooling.
Overall, a thermal management system is an essential part of many modern devices. It helps to prevent damage and increase the lifespan of electronic components and batteries, ensuring that they operate at their best for as long as possible. As technology continues to advance, thermal management systems will become even more important in keeping our devices running smoothly.
Temperature Sensors
The temperatures sensors go hand in hand with the TMS. They are used to relay the actual temperature data to the TMS. This is EVT’s smallest board with the dimensions of 3mm by 7mm. The reasoning behind this is to fit the PCBs into a small bolt that screws into various places on the bike to make sure nothing is overheating.
What’s on the board?
The board has two components: a digital temperature sensor with I2C communication and a capacitor. The digital temperature sensor has 4 possible address pins. This is determined by Ground, 5V, Serial Data, or Serial Clock. It has non-volatile memory. With this, we’re able to still capture any information in case the power to the sensors gets cut off.
Soldering these boards are no joke!
There are 20 boards that come on one PCB sheet. Due to the size, soldiering the boards become extremely difficult to make sure both components are properly connected and there are no solder bridges. While a stencil helps with the two components, there are still four wires that need to get soldered to send the information to the place it needs to get to and receive the required power it needs.
