Now know that the electric bicycle fire accident will once again cause everyone to discuss whether the electric bicycle lithium battery is safe, and perhaps even many people do not understand, since the lithium battery is not so safe and not cheap, then simply continue to use the lead-acid battery is not OK?

In fact, it is not impossible, but consumers may not pay. The new national standard of electric bicycles is indeed a factor, such as the vehicle weight limit will be within 55 kilograms.

Let‘s take the conventional electric bicycle 4820, 48 volt, 20 amp hour battery as an example: although less than one degree of electricity, if the lead-acid battery is used to do it, the weight of almost 20 kilograms and the weight of lithium batteries is about 8 kilograms.

So the question is, would anyone want to carry a 20-kilogram battery around in their car all day? Although we say it may be bulky to ride, if you need to disassemble it to charge it may be physical work.

In addition, more and more manufacturers are likely to produce larger capacity and longer range models as much as possible.

That lead-acid is certainly not suitable, so at least in the field of electric bicycles, lead-acid batteries will be gradually phased out by the market. And the advantage of cheap will eventually offset the actual demand for lightweight.

That on whether lithium is safe, we conclude that the safety of lithium batteries is not as low as imagined, and lead-acid batteries are not as high as imagined.

On the one hand, the insecurity of lithium batteries is a technical problem

This can also be changed, on the other hand is the cost control issue, it depends on human nature.

The change theory is also mainly the behavior of the market, in the security industry there is such a word: risk is absolute, security is relative.

So you will find a lot of problems, if the fan is in place, the fire is very large. For example, pesticides have been officially harmful to human health, but they are allowed to be used in agricultural production, and there is a certain amount of residue of pesticides in agricultural products.

That dose is not 100% safe, but the risk is minimal. Let‘s get back to the heart of today‘s discussion, the topic of security: Is security the most important thing? Yes. Safety is a prerequisite for all production activities.

But is 100% safety the most important thing? Not really. So as long as the risk is controlled, it can be accepted.

Lithium batteries have their own unique advantages, and their risks are basically accepted by the mainstream, so it can replace lead-acid batteries in many fields.

Finally, lithium batteries often explode, which is actually quite subjective. After all, we live in an intelligent terminal era, and the speed of information transmission is faster and the scope is wider.
