Lithium batteries for electric vehicles are afraid of freezing. Lithium batteries are inherently difficult to discharge at minus 10°C because the electrolyte solidifies. Under low temperature conditions, the activity of the lithium battery and the lithium insertion activity of the negative active material will be affected, resulting in reduced battery capacity and reduced flow performance.
The optimal driving environment for lithium-ion electric vehicles is when the temperature is around 25°C. Due to the cold weather in most areas at this time, the battery capacity will also decrease significantly. Due to the special properties of lithium batteries, the battery capacity will attenuate to varying degrees at low temperatures. Specific reference: -10℃, usable capacity is 70%, 0℃ is 80%, and 25℃ is 100%.

Remarks
1. Charge the vehicle at an ambient temperature of 0℃~35℃. is weak. The system will turn off the charging function when the temperature is 0℃.
2. After being fully charged, you can charge it for another hour. Do not charge more than 12 hours for the N50 and 15 hours for the N80. Avoid overcharging, which will affect battery life.
3. If you turn off the battery for a long time, please store it with the battery at 50%, keep the room temperature between 0℃ and 20℃, and charge the battery at least once a month. If battery power is stored below 20% or above 90% for a long time, it will cause irreversible battery power degradation.

Guoxuan Hi-Tech is good.
1. Guoxuan was founded in 2006 and Ningde in 2011. Both companies focus on lithium batteries, and Guoxuan has always focused on lithium iron phosphate. lithium iron phosphate batteries.
2. Guoxuan Hi-Tech's lithium iron phosphate has better high temperature resistance, while CATL's ternary lithium battery is low temperature resistant. For safety reasons, we finally chose lithium iron phosphate.
