Weak current College】 【lead-acid battery repair FAQ inductive】.

Recently, electric vehicle batteries has become a lot of friends interested in the topic, because electric vehicle batteries knowledge not only helps them to better use of electric vehicles, but also for electric vehicle battery repair and maintenance of a very good guide, many friends think electric vehicle battery broken, deformation, and not in power, in addition to the replacement of the electric car battery nothing, in fact, this is not correct, because the batteries are chemical reaction, so regular battery repair maintenance for electric vehicle batteries is very good, but for most normal users for simple battery repair issues or need some attention, let's look at the issues that are fixed on the battery.

1, battery repair process if you need to open the battery?

Answer: not necessary.

2, battery repair process?

A: first of all on the battery to the initial test, and then the actual status of the battery with security systems products on battery for maintenance, development of inspection plans, detection and polling battery status on a regular basis.

3, curing effect on electric vehicle batteries?

A: the curing effect of polarization, battery charge acceptance, validity, and active substance discharge end voltage drop fast, low-rated capacity. Is charging, the voltage rise faster, electrolyte density up to the specified value, the excess produce gas decomposition, pool temperature is high. Chemical reactions, molecular contact area small, the reaction of energy.

4. how to determine electric vehicle battery has been repaired?

A: by using electrical BA or battery repair system for a period of time, through testing batteries, electric vehicle batteries capacity reaches 85% of rated capacity or above can determine the electric car battery has been repaired.

5, maintenance-free batteries also need this kind of maintenance?

A: you need. Maintenance-free batteries easier curing, new battery protector, desulphurisation look better, but because of the maintenance-free battery electrolyte will dry up, life is not like the orifice lead-acid battery repair can be extended too much.

6, electric vehicle batteries life extent depends on curing?

Answer: 80% of the electric vehicle batteries due to curing the battery life.

7, battery repair to 100 per cent of what to do?

Answer: the electric car battery at greater than 10 times the rate of discharge, up to 100% of these are very common.

8, auto-start current of the battery?

Answer: 3-4 times the rated capacity.

9, electric vehicle batteries for curing degree of depth is there a simple way to test?

Answer: 1, with 3 minutes to 40A charging voltage exceeding 15V, indicate a curing, if less than 15V description battery is good.

10, the simplest solution: charge, end-to-peak voltage rise fast and high, single cells in about discharge 2.9V, Terminal voltage drops faster charging electrolyte density lower than ended, the normal value and performance for a long time lag, the normal discharge, the battery plates occurring sulfur than other battery capacity significantly low. Charging battery gas exploded early, at the risk of gas heated, pool temperature is high, the positive plate appears light brown, negative plates is grey, the surface is rough particles lead sulfate.

11, electric vehicle batteries, without any identification of cases?

A: check the volume, according to a electrolytic and voltage control, electric vehicle batteries for three and two-and-drop detection capacity.

Want more friends using the electric vehicle batteries, can pass these issues summarized for your electric vehicle battery maintenance and battery repair gain good, hope you can better maintain your vehicle.
