Lithium battery suddenly exploded? Expert: It is very dangerous to charge lithium batteries with lead-acid battery chargers

According to data released by relevant departments, there are more than 2,000 electric vehicle fires across the country each year, and lithium battery failure is the main cause of electric vehicle fires.

Since lithium batteries are lighter in weight and larger in capacity than traditional lead-acid batteries, many people will replace them after purchasing lead-acid battery electric vehicles.

Most consumers do not know the type of battery in their vehicle. Many consumers admitted that they would usually replace the battery in a refurbishment shop on the street, and would continue to use the previous charger.

Why does a lithium battery suddenly explode? Experts say that it is very dangerous to use lead-acid battery chargers to charge lithium batteries, because the voltage of lead-acid batteries is higher than that of lithium battery chargers if the voltage of lead-acid batteries is the same voltage platform. If charging is carried out under this voltage, there will be a danger of overvoltage, and if it is more serious, it will burn directly.

Industry insiders told reporters that many electric vehicles decided at the beginning of the design that they could only use lead-acid batteries or lithium batteries, and did not support replacement. Therefore, many modification shops need to replace the electric vehicle controller together with the electric vehicle controller, which will affect the vehicle. Security has an impact. In addition, whether the charger is an original accessory is also the focus of consumers’ attention.

Firefighters reminded that batteries purchased through informal channels may be at risk of recycling and reassembling waste batteries. Some consumers blindly purchase high-power batteries that do not match electric bicycles in order to reduce the number of recharges, which is also very dangerous.
