Summer high temperature Two wheeled electric vehicle fire accident frequent, how to prevent?

In recent years, Two wheeled electric vehicle fires have still been emerging in endlessly, especially in the summer high temperature, electric fire is easy to spontaneous combustion!

According to the 2021 national fire rescue team receiving police and fire data released by the Fire Rescue Bureau of the Ministry of Emergency Management, nearly 18,000 fires caused by Two wheeled electric vehicle and their battery failures were reported nationwide, killing 57 people. According to reports, in just half a 2022 year this year, there were 26 Two wheeled electric vehicle fires in Yantai.

What causes Two wheeled electric vehicle fires so frequently?

The main culprit behind the spontaneous combustion of Two wheeled electric vehicle is the thermal runaway of lithium batteries, the so-called thermal runaway is a chain reaction triggered by various incentives, and the heat can make the battery temperature rise by thousands of degrees, resulting in spontaneous combustion. Two wheeled electric vehicle battery in overcharge, puncture, high temperature, short circuit, external damage and other reasons easily cause thermal runaway.

How to prevent thermal runaway effectively

The inducement of thermal runaway is multiple, so multiple preventive measures should be made to prevent the occurrence of thermal runaway.

The main cause of thermal runaway is “heat”, to ensure that the battery has been running at a reasonable temperature, in order to effectively prevent the occurrence of thermal runaway. However, in the summer high temperature, “heat” is unavoidable, then you need to start from the battery, so that lithium-ion batteries have better heat resistance and heat dissipation performance.

First of all, consumers need to pay attention to the related characteristics of lithium batteries when purchasing two wheeled electric vehicles, and whether the internal material of the battery cell has good temperature resistance and heat dissipation performance. Secondly, whether the connector connected to the battery inside the electric vehicle has high temperature resistance performance, to ensure that the connector will not soften and fail because of high temperature, so as to ensure that the circuit is smooth and avoid the occurrence of short circuit.

As a professional electric vehicle connector expert, AmasS has 20 years of experience in research and development of lithium electric vehicle connectors, and provides current-carrying connection solutions for two wheeled electric vehicle companies such as SUNRA, AIMA, YADEA. Amass high temperature two wheeled electric vehicle connector adopts PBT with heat resistance, weather resistance and good electrical characteristics, and the melting point of PBT insulated plastic shell is 225-235℃.

High temperature two wheeled electric vehicle connectors have passed the flame retardant grade test, flame retardant performance up to V0 flame retardant, can also meet the ambient temperature of -20 ° C ~120 ° C. For use in the above ambient temperature range, the main shell of the two wheeled electric vehicle connector will not soften due to high temperature, resulting in a short circuit.

In addition to the selection of the battery and its components, the quality of the electric vehicle charger, the charging time is too long, and the illegal modification of the two wheeled electric vehicle is the key to the improvement of the safety performance of the electric vehicle lithium battery.
