Proper use and maintenance of batteries for electric vehicles often drive an electric car for people who travel, have a good method of charging and charging frequency is the key. Early use of batteries for electric cars are powered new electric passenger tricycle, but with superior performance lithium appear, the battery will gradually fade into history, the focus of attention has gradually shifted to lithium maintenance up. Lithium batteries for electric cars electric passenger tricycle manufacturers partial discharge, rather than fully discharged electric passenger tricycle, and to try to avoid frequent full discharges. Once the battery under the production line, the clock began to move around. Whether you use a lithium battery life of only two to three years. Decline in battery capacity due to the increase in internal resistance due to oxidation (which is the main cause of the decline in battery capacity). Highly-charged state and increased temperatures will accelerate the decline in battery capacity.
