Battery life is, battery repair just keep
it reaches normal design life. To promote the product to any factor battery
repair battery repair the damage with the new batteries, ensure that the
battery life can be extended many times, these are not scientific, it is not
realistic. Without any damage to the battery of any factors, have an impact on
the battery life, the question is how to reduce the damage to the battery, how
to reduce the impact on battery life, following a brief introduction of several
electric vehicle battery daily maintenance method for your reference.
Lead-acid batteries have no
memory, so the capacity to rapidly decrease was primarily sulfide batteries and
"dehydration", "loss of power" and for some reason, fear is
the battery "power loss" Brown, batteries often "power
loss" battery pole board easily injured, we found that up to 70 percent of
the electric vehicle battery capacity to reduce high current (starting current)
strain discharge electrode plate is caused (electrical 摩尤 its obvious), strain belonging to the
battery electrode plates physical damage, this damage can not be repaired.
Therefore, "every car, every charge" to ensure that there is always
sufficient battery voltage has become inevitable.
Users generally thought, maintenance-free
batteries do not add water, in fact, this statement is wrong. Maintenance-free
battery charging and high-current discharge process generates heat, there will
be a heat evaporation, although the process is very slow evaporation of water,
but over time, the cumulative amount of water evaporation on can not be
overlooked.
Electric car start clever force. Electric
car start-up current is large, especially in high-power electric motor
friction, higher starting current. It hurt a large current battery plates, the
best way is like riding a bicycle after riding before you start, and then start
the electric car power supply. Of course, many electric motor means no riding,
which is no other way.
Quarterly on the battery deep discharge
once. After the battery is bound to use for some time to sink some active
substances, if not promptly activate the active substance is bound to cause
some impact on the battery capacity, so often used in electric car, the battery
should be done on a quarterly basis depth of discharge once.
Frequently observed charger is good or
bad. New battery charging process is generally 6-8 hours, the charger will
light green when fully charged, the charging time is too long if necessary to
check whether the charger voltage protection device corrupted, corrupted if you
need immediate replacement charger or vulnerable to charge a bad battery. Also,
do not buy fast charger charger for fast charging battery plates have the same
injury.
Long battery when not in use for at least
a month to give the battery charging time. The aim is to prevent the battery
from the battery caused by placing too long curing and "loss of
electricity."
Prevent the battery from prolonged sun
exposure. Prolonged sun exposure can cause the battery temperature rises, so
pay attention.
The above part of a more comprehensive
description of the battery damage, repair, and maintenance of the relevant
skills and knowledge, which is based on our years of experience and market
feedback information written in simple language articles, layman understand at
a glance. At the same time, we also sincerely reader from one side of the
electric car battery repair techniques uncover the mystery, which is battery
repair can take many methods, but not all damage to the battery are effective,
curing illnesses and small battery restored effective; plate mild softening,
short circuit, may be effective after a short break after every repair, as supernatural,
as will the use of time is not long fallen into place; also some very serious
damage to the battery, repair largely ineffective, introduction this knowledge
is mainly to facilitate the reader's understanding of the industry initially
make the right choice on battery maintenance and repair.
After passing electric car batteries by
battery manufacturers factory, battery life and performance depends in part on
consumer use and maintenance.
(1) Matching charger and battery.
Electric car batteries are rechargeable
bad, rather than bad, showing the importance of the charger and the battery
match, there are two situations: First, the new parameters and battery charger
provided by the manufacturer itself does not match, the charging voltage is too
high and aggravated battery water loss, shortened life expectancy, more serious
is the charge current drops to less than the current value of the conversion
settings, battery temperature, charging current is further increased, the
temperature rise much, resulting in thermal runaway cell expansion and
deformation, and vice versa charging voltage is too low, the battery charge
state owe a long period, not always part of PbSO4 conversion, resulting in
sulfate, battery capacity drops, electric bikes continues the course shortened.
Second, poor quality components charger itself, just started, fairly matched,
as consumers charge and discharge cycles used. Charger itself due temperature,
aging of components, resulting in the charging voltage and switching current
drift, battery damage.
It is recommended that consumers and
manufacturers of electric vehicles is best to buy a battery charger
manufacturers supporting, not because it is cheap and filling joie de vivre of
a bad battery, but not worth the candle.
(2) Often, replenish electricity.
Consumers using the nominal cycle life
instructions usually have a misconception that one charge, the battery life is
reduced once, so every time the battery power consumption, such as the
protection voltage 31.5V to the controller began to supplement electricity ,
not knowing that not only can not protect the battery and shorten battery life.
Because the positive active material is not strong PbO2 itself combined with
each other, and the molar volume of PbO2 and PbSO4 are very different, more
shallow depth of discharge, contraction, the lower the degree of expansion.
So remind consumers, where possible, the
battery should charge it in time.
(3) Prohibited under undervoltage
condition indicator shows continue riding. Some consumers after riding half
way, the indicator displays the status of undervoltage take rest a re-ride some
way, such great harm to the battery, the battery will discharge over serious
salinization or lead generation branches crystal, short circuit the battery,
affect life expectancy.
(4) electric bikes just starting,
climbing, overloading should try to help.
(5) rain riding, switches and connectors
should try to avoid getting wet, to prevent leakage.
Know more about some aspects of the
knowledge about the battery lead-acid batteries for electric bikes maintenance
and repair have positive side, through technical improvements compared with the
great advantage especially to improve the colloidal technology, cost-effective
lead-acid batteries and other batteries.
General Electronics Battery Co., Ltd. electric vehicle battery has
been committed to the development, production, for consumers to create a safe,
environmentally friendly batteries.
