E-Scooters
In times of Fridays for future movements and green technology developing faster than ever, new energy applications are also more widely used. The application of electric scooters is one of the pioneers in this field. Indeed, the development of e-scooters involves many benefits such as using small lanes, being eco-friendly, having high efficiency and being priced at a reasonable amount to be accepted by broad masses. This explains why this industry is growing at an enormous pace. But this situation also brings any disadvantages such as lack of quality from some suppliers, overloaded power and improper use, where the main issue is the energy consumption of the power battery. As the incorrect use and charging could cause severe accidents, local governments and departments place emphasis on the safety of e-scooter development.

The same problems that often get criticised when talking about electric cars also apply on this issue. Long charging time and the rapid decline of power storage capacity are just few of many issues. In order to solve these problems, manufacturers now tend to use high energy density battery packs. The high voltage fast charging and high efficiency discharging will trigger a part of the chain reaction.
The uneven distribution of heat – a large difference between the operational internal and external temperature – not only reduces the life span rapidly, but also produces much higher maintenance costs.
Non-effective thermal conductivity accelerates battery aging when the reasonable battery temperature is exceeded and will cause thermal failure, sometimes up to a fire, and includes other severe safety issues as well.

According to the analysis of a thermal situation test, the highest temperature is nearly close to 52℃. At this point, the temperature difference between the inside and the outside of the battery pack reaches to 27℃. The partial temperature is considerably higher than the battery efficient operation temperature (10-30℃), leading to partial thermal runaway and triggering potential safety risks.
The thermal situation test together with an actual test for the product structure predict that the thermal distribution effect of an electric car power batter pack is similar to the new energy battery pack used for instance in e-scooters. But due to the spatial limits, the costs and other components, it cannot remove heat by large area air-cooling or water-cooling ….
According to actual heat dissipation demand, you need to adopt soaking, the thermal structure layer and the air-cooling to achieve the maximum heat dissipation in the limited structure space.
Based on customer’s structure requests to customize professional, efficient soaking and heat dissipation structure, you need to reduce the temperature difference between the inside and the outside of the battery pack by 30℃, meeting the battery pack operation temperature when reaching soaking and effectively avoiding potential safety risk of thermal failure during charging and discharging at the same time.
-> using thermal interface can create homogenous heat dissipation
