Five Tips To Double The Battery Life Of Your Electric Car

How to extend your electric car battery cycle life, there are 5 tips from the research data from SmartPropel.If you follow below structures, I’m sure you will benefit a lot from them.

1. Note the working environment temperature

Lithium-ion batteries are afraid of overheating as well as being too cold, should not be used in extreme environments. Many people like to leave their lithium-ion battery electric cars in the sun in the summer, or park in the yard or on the main road in the winter. This is detrimental to the service life of lithium-ion batteries. This is detrimental to the service life of lithium-ion batteries. Theoretically, the battery can work normally between -20℃ and 55℃. In daily life, there is no harm to the lithium battery when the temperature is between 5℃ and 35℃. Customers in the north try to park their lithium-ion battery cars indoors rather than outdoors in the winter, and those in the south try to prevent them from being exposed to the sun in the summer.

2 Lithium-ion batteries should not be deeply charged or discharged frequently

A lot of people think that the lithium-ion battery in the electric car manual can only be used once if it is plugged in for hundreds of cycles, but this is actually a mistakes. The number of battery cycles listed in the manual refers to the number of complete recharges and discharges. Unlike nickel-cadmium batteries, lithium-ion batteries have no memory effect and can be recharged anytime, anywhere. Charging the battery with excess power will not shorten its service life, but also maintain the battery and extend its cycle life. With lithium-ion batteries, the right approach is slow charging rather than deep charging.

3.Charge with a suitable charger to prevent high current

Lithium-ion batteries are much more chemically reactive than lead-acid batteries and require a higher level of chargers. Once using off-brand charger or unsuitable fast charger, it will not only affect the service life of lithium ion battery itself, but also cause explosion due to the damage of diaphragm caused by overheating and short circuit. In addition, if your battery discharge ratio is lower than the discharge current of your electric car, it will lead to the lithium ion battery temperature is too high, the current is too large and the life is shorter, may also appear the bulge scrapped situation. Please according to your electric vehicle discharge current requirements to choose the appropriate discharge rate cell, so choose the right cell is obviously very important! You should read the battery specification sheet carefully before charging it. For example, SmartPropel 72V150Ah lithium battery pack maximum charge current 75A and pulse discharge current 150A, it will fit for the motors which the peak power is lower than 10KW.

4 .Do not overcharge. Lithium-ion batteries do not need to be activated

Many users charge their new lithium ion batteries for 10-12 hours in the first three times according to the method of lead-acid battery. They think that the lithium ion battery needs to be activated, but actually doing so has a huge impact on the life of the lithium ion battery. There is even a bizarre belief that trickle-charging is the practice of charging a lithium-ion battery for another hour after it has been fully charged to counteract internal resistance, these are all wrong. The right thing to do is to just unplug it when it’s fully charged. Lithium-ion batteries in electric cars should not be charged overnight, which is prone to fire.

5.Do not be stored at full charge

Generally, the newly-purchased lithium-ion batteries in electric cars are 60-70% of the power, and few of them are fully charged. Long storage time at full charge will reduce the capacity of lithium ion battery. Batteries that have not been used for a long time need to be charged and discharged regularly. In addition, but also pay attention to the choice of better quality BMS. You can learn more charging skills and notes from Top 5 Charging Skills and Notes for Electric Vehicle Battery Pack in 2020.

Notice these tips, your electric car’s lithium-ion battery will be fine for five or six years.
