Recently, a friend asked me, the new national standard has come out, can you replace the lead-acid battery of your electric car with a lithium battery? For this problem, as a mechanic to give the advice not to change, why so? First of all, everyone knows that after the new national standard was introduced, there were strict regulations on the standards of electric vehicles, which means that the testing of electric vehicles will be stricter On the other hand, companies must also have 3C certification and electrical qualifications.
