How to choose a lithium battery charger when the cooling is on?

As the temperature gradually decreases, the pace of people's lives is significantly slower than in summer, and EV owners have a deeper understanding that the range in winter is significantly shorter and the charging time is longer.

Why does the range of electric vehicles decrease in the cold winter?

The electric car on the market is mostly lithium battery energy storage. The lithium battery principle is a "rocking chair" electrochemical energy storage process. The lower the temperature, the worse the activity of the lithium battery, which directly leads to a significant reduction in charging and discharging efficiency, in general, the working temperature of lithium batteries is between -20 ℃ and 60 ℃.


In winter, how to maintain the lithium battery and reduce the degree of damage to the lithium battery in winter.

1.Do not use lithium battery in low temperature environment

When the temperature is lower than -20℃, the battery may automatically enter the hibernation state, which is harmful during use.

2.Charge as you go

When the battery is too low, charge it in time and charge it as you go.

3.Do not charge for a long time

Fast wheel system products, charging time is 1.5 ~ 3h, full that pull. When charging, do not leave to prevent unexpected situations.

4.Use regular charger

Use of poor quality chargers, lithium batteries will be damaged, and may even cause a fire. If you need to replace the charger, please buy a regular charger on the regular channels to protect the quality of charging.


How to choose the right Lithium Battery Charger?

The importance of the lithium battery in the electric car is beyond doubt, then the charger is also particularly important, the charger performance is good or bad, will directly affect the service life of the lithium battery.

1, confirm the voltage of the electric car battery

If the battery voltage is 48V, the output voltage of the corresponding lithium Battery Charger is 59V; if the battery voltage is 60V, the output voltage of the corresponding lithium battery charger is 73.5V. and so on.

2.Confirm the battery capacity of the electric car battery (AH)

If the battery is 12AH, the output current of the chosen charger is 18A; if the battery is 20AH, the output current of the chosen charger is 26 to 30A. The output current of the chosen charger is slightly larger than the battery capacity.

3.Confirm the electric car charger interface shape - positive and negative pole

There are generally four types of interface types on the market, T-shaped pin head, medium horizontal pin head, three vertical pin head, round head.

Superpower produces electric motor lithium battery charging connector with torsion spring jack structure through independent research and design to ensure product quality. The connector contact parts are silver-plated copper material with low impedance and excellent conductivity. In the process of use, the contact surface residual corrosion layer off due to the plugging process can minimize the generation of electrical isolation. Unique shape, frosted surface, outstanding texture.
