How to care for lithium-ion batteries? How to care for a high voltage battery in an electric car? What to do in order to not need to repair a lithium-ion battery in an electric car?
Electric cars are powered by high-voltage batteries, which consist of about hundreds, connected in series, single purpose lithium-ion batteries.
A single lithium-ion cell fully charged is about 4.2 V. Thus its nominal voltage is 3, 75V. Minimum voltage at a temperature greater than-20 degC equal to 2.7 V. The result of this lithium ion battery operation in the range of 0%-100% of the charge is only between about 3.0 V-4.2 V. Any discharge below the minimum value causes damage to the package.
Lithium Battery „does not like” be left either fully charged or discharged to a minimum. The voltage (for purposes) closer to the nominal value (3, 75V or about 50, 55% of the charge status), the lithium battery is more stable close to the equilibrium point. It follows that the closer to 50% of the charge (about 3.75 V/goals), the battery will last longer for us to
serve. A very good example is a new smartphone, just removed from the box. On your new phone just after you start the battery status is never on FULL. But I never have a level of a few, up to a dozen percent. When turned on, it turns out that the charging status is about 50%. This is called the LiIon battery sleep state. The lithium battery (charged at the STORAGE option) can be left in this state for up to 5 years.
How do I take care of lithium-ion batteries in an electric car? Remember! Never leave a fully charged or completely discharged lithium ion battery for a longer period of time. This will protect you from a visit to Serwis Pojazdów Elektrycznych electric car service on often quite long-lasting operation of high voltage Bateri repair.
