Nowadays, electric vehicles are increasingly developing towards high-end intelligence. The research and manufacturing technology of electric vehicles is constantly improving, and the production process of electric vehicles is also becoming increasingly mature. But there is one drawback that ha...

From the perspective of market demand Due to mandatory weight regulations, a set of 48V12A lead-acid batteries weighs around 15 kilograms. Due to the physical properties of lithium metal or lithium-ion, the weight of a lithium battery with the same capacity is only one-fifth...

In recent years, the government has attached great importance to environmental protection. With the official implementation of the new national standard policy in April 2019, the weight of electric vehicles has been limited... The concentrated implementation of a series of policies has confirm...

With the implementation of the new national standard for electric bicycles last year, the lithium battery industry has ushered in a new era. At major exhibitions, the proportion of lithium batteries has surpassed that of lead-acid batteries, gradually gaining market recognition. The reduction...

Some people may ask, why not use a lithium battery with a larger capacity? For example, the lithium battery of 48V32Ah and 48V50Ah lithium-ion batteries can achieve a range of over 200 kilometers for electric vehicles. In terms of current technology, lithium batteries are not yet very mature....

The two major constraints of electric bicycles are their speed and their range. The new national standard for electric bicycles imposes strict limits on the maximum speed of vehicles, requiring a speed not exceeding 25km/h. But there are no restrictions on the range. In theory, as long as the...

According to experts, the battery products currently used can be roughly divided into three categories: primary dry batteries (ordinary dry batteries), secondary dry batteries (rechargeable batteries, mainly used in mobile phones and computers), and lead-acid batteries (mainly used in automobi...

A new type of acid free battery - lead-oxygen battery has recently passed the testing of national authoritative institutions, and all indicators have met or exceeded national standards. This means that the battery technology with a history of 150 years has achieved a revolutionary breakthrough...

In addition, there should be no double standard for lead-acid batteries. For example, Yang Yusheng said that every fuel powered vehicle now uses a lead-acid battery, and the hundreds of millions of fuel powered vehicles nationwide represent the usage of hundreds of millions of lead-acid batter...

Wei Xueqin Secondly, the low-speed electric vehicle industry has shown positive changes in policy, market, and product aspects, especially the general improvement of product performance. Wei Xueqin introduced that in the first national small electric vehicle testing competit...
