The first charging notice for new electric vehicles is as follows:
1. When charging for the first time, don't ride completely without power. Under normal circumstances, the new electric car will not have too much power, and it will not be too small. When riding to the last grid of the battery car, you can prepare to charge.
2. When charging for the first time, choose to charge during the day. Charging a ternary lithium-ion battery at night is prone to overcharging and damaging the battery. In the daytime, it is easy to control the charging time during charging, and pay attention to the time when charging.
3. When charging for the first time, be sure to fill it in 5-6 hours. Because the battery car battery has not been used before delivery, it has not experienced charging and discharging, so the charging time should not be too long.
4, the second charge, you can choose deep discharge, and then a long-term charge, this charge can be maintained for 8-9 or even 10 hours, in order to let the battery car chemical reaction for a complete charging cycle.
5. If the battery is charged for the first time in the summer, the ternary lithium-ion battery charger may generate heat quickly and the heat is very high, so the charger should not be placed on objects that are prone to heat and burn, and it is best not to put it on. On the seat of the battery car, prevent fire.
1. Purchase electric vehicles with quality assurance
When purchasing an electric car, you should choose an electric car with quality assurance. Don't buy inferior products because you are cheap.
2, the vehicle is placed
Do not park the electric car in the aisle, safety exit, etc., in case of danger, causing unnecessary personal and property damage.
3. Charging location
When charging, you should choose a wide area. Do not squeeze in a small and occluded space. This is not safe, but also gives you room to react. At the same time, you should pay attention to avoiding moisture, oil and other environments when choosing a location.
4, charging time
When charging a ternary lithium-ion battery, it is best to choose it during the day. Try not to charge the electric car for one night. Pay attention to the charging time and let the danger come.
5, avoid overcharging
The charging time should be controlled well. It is best not to exceed 8 hours. If the battery is not charged, the battery life will be shortened and the voltage may be too negative.
6, regular maintenance
Buy electric vehicles should also pay attention to regular maintenance, check the lithium manganese oxide lithium ion battery charging line and plug from time to time to avoid the danger of line aging, short circuit and so on.
There are no strict requirements for hydrochloric acid batteries. However, it is best to fill when charging, lithium iron phosphate lithium ion battery charging time is long, the general charging can take a few hours to be full, and then hang for a few hours, you can. But be careful, don't use the fast charge to charge the first time. However, the battery you have purchased is a trial battery that is specially equipped by the manufacturer (the same is true for regular manufacturers, for profit). This battery does not know how many cars have been replaced, but the manufacturer keeps repairing. So, if you are buying a battery with a new car, you don't have to care, just charge it. No matter what charge, you must be damaged within one year, then go for free replacement. (Of course, if you don't pay attention, change it to your trial battery) So pay attention and polish your eyes.
If it is your new battery, then pay attention to it. However, according to my personal experience, if your battery is 48V20A, it is best to charge it with 12A (filling with 20A for half an hour), the time will be slower, but it can extend the battery life. Minimize the use of fast charge outside.
The ternary polymer lithium battery refers to a lithium battery using a nickel-cobalt-manganate (Li(NiCoMn)O2) ternary positive electrode material as a positive electrode material, and the ternary composite positive electrode material is made of nickel salt, cobalt salt and manganese salt. The ratio of nickel-cobalt-manganese can be adjusted according to actual needs. The battery with ternary material as the positive electrode is safer than the lithium cobaltate battery, but the voltage is too low, which is used on mobile phones (the cut-off voltage of mobile phone is generally around 3.0V). The feeling of insufficient capacity. 
The ternary polymer lithium battery refers to a lithium battery using a lithium nickel cobalt manganese ternary positive electrode material for a positive electrode material, and a lithium iron phosphate lithium ion battery has a plurality of positive electrode materials, mainly lithium cobaltate, lithium manganate, lithium nickelate, Ternary materials, lithium iron phosphate, etc. At present, the ternary material battery replaces the widely used lithium cobalt oxide battery, and is widely used in the field of notebook batteries.
Lithium manganate lithium-ion battery is more balanced in terms of capacity and safety. The cycle performance is better than that of normal lithium cobaltate. In the early stage, the nominal voltage was only 3.5-3.6V due to technical reasons, and there are restrictions on the scope of use, but At present, with the continuous improvement of the formula and the perfect structure, the nominal voltage of the battery has reached 3.7V, and the capacity has reached or exceeded the level of lithium cobalt oxide battery.
SANYO, PANASONIC, SONY, LG, and SAMSUNG have launched batteries for ternary materials. A considerable number of notebook battery lines have replaced the previous lithium cobalt oxide batteries with batteries of ternary materials, SANYO. In the SAMSUNG column battery, the production of lithium cobalt oxide batteries turned to ternary cells was completely discontinued. At present, most of the small high-power batteries at home and abroad use ternary cathode materials.
