On February 13, this year, the Ministry of Finance and other four departments jointly issued the Notice on Adjusting and Improving the Policy of Financial Subsidies for the Promotion and Application of New Energy Vehicles (No 18 of Finance Construction).

Lead carbon batteryLead carbon is a new type of super battery, battery is a lead-acid battery and super capacitor combination: both played a super capacitor moment both the advantages of large capacity rechargeable also played a lead-acid battery than energy advantage, and have very good charge-discharge performance - 90 minutes to charge (lead-acid battery if such a charge, discharge, life less than 30 times)And because of the added carbon (graphene), to prevent the phenomenon of cathode sulphates and improved the battery failure of a factor in the past, more longer battery life.

1, Regular inspection: Whether it is a drive vehicle or a new energy vehicle, regular inspection of the car situation is an essential link If the mileage of a new energy vehicle suddenly drops dramatically during use, it is likely that at least one battery in the battery pack has a problem and should be rushed to the repair shop to deal with it in time.

In recent years, since the dwindling of fossil fuels and the greenhouse effect is revealed, as a clean, efficient and abundant secondary energy, the hydrogen has attracted the attention of more and more countriesProfessor of Tongji University, Shanghai hydrogen by using engineering technology research center, deputy director of the Zhang Cunman pointed out that the development of the hydrogen involving production, storage, transportation and use.

In the era of Ningde, BYD's battery business is trying to stop closing supply chain system, and frequent negotiation with several automotive OEM BYD Qinghai lithium battery production base is put into production, which will be able to support more battery products flow outward in the future.

This is a very real problem, if the future of electric vehicles, the accidents (collision, bubble water), how to effectively monitor and detect? Personal ideas, is through a dedicated circuit block, about such a design prototype:1) has the multiplex power input, can be in 12 v battery work and battery doesn't work to hang outside into the 12 v configuration possibilitiesNote: this is similar48 v battery function of exhaustion forced charge design considerations.

Now the development of digital super lithium battery, the use of international high quality premium batteries, lithium for each battery manufacturer produces various types of mobile phone parameters for precise calculation, has high precision for discharge, over charge, over current protection of electronic circuit, can achieve the best use effect, and internally USES the microcomputer circuit device Choose the internal resistance of the different according to the mobile phone to adjust current, not only guarantee the stability of the circuit resistance, lower power consumption, but also extend the standby time, so it is also a kind of smart products.

In small capacity UPS, in addition to the standard itself around 30 min co, LTD battery matches outside quantity, users often need to extend battery backup time, generally in the large capacity of UPS, no standard battery, but according to the needs of the match.

In fact, the smart mobile phone tends to use lithium battery It's not so fragile as your imagination.

Electric cars will take in the future lithium battery as the main source of power driven, lithium is the main reason why battery has advantages of high energy density, so more stable performance However, lithium battery when mass production quality is not easy to master, battery core factory capacity is slightly different, and the factors such as operating environment, aging, inconsistencies between the battery will be increasingly apparent, battery efficiency, life will become worse, plus a charge or discharge, etc.
