1, Wei Chao battery is the first enterprise to apply graphene technology to batteries, and graphene technology is relatively more mature. In particular, the upgraded version of Wei Chao black gold battery developed on 20 17, based on the first generation of Wei Chao black gold, has been upgraded in an all-round way, further improving the core technology of graphene alloy, and adopting a unique "constant pole" structure, making the product more stable in performance and longer in service life.
The patented technology of "graphene alloy" has greatly improved the battery capacity, and at the same time, its frost resistance, load capacity, climbing performance, service life and battery stability have also been comprehensively improved, which has won unanimous praise both inside and outside the industry.
2. Tianneng battery also perfectly integrates black gold with the battery, which increases the durability of the power battery, prolongs the service life, and solves the pain points of the previous industry that the battery is not durable, easy to bulge and afraid of low temperature. Moreover, in order to remind consumers to choose genuine black gold batteries, the product is named true black gold batteries.
Battery purchase method:
1, check whether the product identification of electric vehicle battery is complete.
Including the manufacturer's name, product specification and model, manufacturing date and trademark; Check whether the internal and external signs are consistent, especially whether the product itself has eye-catching signs and production dates.
2. Pay attention to the appearance of electric vehicle battery.
Check for deformation, cracks, scratches and leakage marks. The battery terminals shall be clean and free from rust, and the signs shall be clear.
3. Pay attention to the rated capacity marked on the battery products of electric vehicles.
The larger the rated capacity of the battery, the longer the battery discharge time. It is best not to buy batteries without rated capacity, but pay attention to whether they are special for electric vehicles.
4. Buy brand batteries from well-known enterprises and large enterprises.
Batteries are generally provided by professional battery manufacturers. Different brands and manufacturers produce different batteries with different quality and different prices. Well-known large enterprises have large scale, strong technology, good after-sales service and guaranteed battery quality.
5. Choose an automatic control smart charger that matches the battery.
A suitable charger can automatically adjust the charging size and time, which is beneficial to prolong the service life of the battery.
