Electric vehicle battery maintenance asked ten

Battery maintenance ten q ( 1) What kind of battery electric vehicles use? What are the characteristics? A: use valve-control sealed electric power special battery, large capacity, long service life, whole sealing, safe and reliable. ( 2) New purchase of electric vehicles, supplementary charge before use if need? Answer: the demand. Because during the battery in the car for sale, self-discharge phenomenon ( Any battery self-discharge phenomenon) , make the voltage drop, battery storage capacity is insufficient. Added charging methods: with the accessory special charger for a new car to the green light. ( 3) In use process, how to charge? A: charging time according to the length of the range, the longer the mileage, the longer the charge time, on the other hand, are short. Control the charging time 4 ~ 12 hours. Summer charging time reduced, the charger turns green light to continue floating after 1 ~ 2 hours, shall not be charging for a long time. Every time cycling power consumption by 50% ~ 70% charge for the best. ( 4) Electric vehicles are used to under-voltage recharging is better? A: no. Please form the habit of increases with the increasing in charge, keep the battery in the shallow discharge and charge state, promptly supply electricity can extend battery life. ( 5) Electric cars need not when, for a long time treatment of what should be done? A: you must first adequate electricity, and every 1 - later Supplementary electricity once two months. ( 6) Climate, temperature change, have an effect on electric vehicle mileage? A: there are. Battery discharge is an electrochemical process. Temperature is high, fast response, large capacity; On the other hand, the capacity is small. So, winter electric car mileage, significantly shorter than in summer. ( 7) Electric motor, when undervoltage lamp lighting, can make a little stay and continue to drive, so influence to the battery? A: there are. Continue to ride after undervoltage lamp lighting is prohibited. Due to stop riding, voltage will rebound, the electric vehicles can continue to ride again. Continue to ride after the under-voltage, is actually a process of over discharge. Repeatedly over discharge, the fatal influence on the battery. ( 8) Short ride for a long time, will make the battery capacity decline? A: yes. It is recommended that you every 2 months a deep discharge ( A one-time) That long distance cycling, until the under voltage indicator, then immediately restore the battery capacity, charging in this way, can activate cells, but also to understand the status of the current capacity of battery. ( 9) The battery is not the only factors affecting electric car line continuation mileage? A: no. There are many factors of restricting the electric line continuation mileage, in addition to the road, wind, seasons and other natural conditions, there are: battery, motor, controller, charger, etc. , the quality situation of the four items, will be a decisive influence on electric vehicle line continuation of mileage. ( 10) Battery used to a certain period, the capacity is reduced to below 60%, life is about to end, after the maintenance can prolong life? A: the correct maintenance, can extend the life of the battery, the method is: first, open the battery cover, remove the glue, in each single cell battery adding water or density of 1. 5 g/cm3 sulfur acid, just see the flow of liquid, with special maintenance charger to green light, exhaust the flow of liquid, then at 2 h rate discharge current to 10. 5 v/only, general circulation more than 2 times, battery capacity has large improvement ( This work must be carried out under the guidance of professional personage) 。
