BSTRACT
An ordinary resident of our country who has a personal vehicle spends a large amount of money on it. This
is due to the high cost of combustible fuel, regularly scheduled maintenance, rubber replacement and other
minor points. As a result, people are looking for an alternative solution, and an electric car comes to the
rescue. The motor of an electric car has practically no drawbacks, its operation is quiet, it does not need a
regular change of engine oil, and most importantly, it does not pose a threat to the environment. This article
discusses ways to repair and maintain modern electric vehicles.

NTRODUCTION
The maintenance of electric vehicles is almost the
same as that of internal combustion engine
vehicles, with the significant exception of the
power plant, its ancillary systems and
transmission. In the design of all-electric
machines, the same chassis and suspension,
wheel drives, the same basic components of the
steering system, braking, lighting, and many
others. In this part, the frequency and volume of
inspection, adjustment and repair operations will
practically not differ. There is an increase in the
number of electric cars in our country and the
expansion of their range in our secondary
markets.

T
HE MAIN PART
The popularity of electric vehicles, the range of
which in the specialized market is constantly
increasing, is explained by the optimal
combination of car environmental friendliness,
comfort, excellent technical and operational
characteristics, and low maintenance costs. The
maintenance of electric vehicles does require
significantly less maintenance than the
maintenance of vehicles with gasoline and diesel
engines.
A prerequisite for the durability of cars with an
electric motor is timely maintenance. Many
electric vehicle owners ignore maintenance
because there is no need to change the engine oil.
The rules for charging the battery are also not
observed, as a result of which the loss of battery
capacity after two years of operation is about
12%. In order for the electric car to serve for a
long time and without accidents, maintenance
must be carried out in a timely manner. The
maintenance of electric vehicles is not much
different from the maintenance of ordinary cars,
with the exception of the power plant, auxiliary
systems and transmission systems, and the
battery.
Electric cars are a prerequisite for long-term
service, which is timely maintenance (TS). Since
there is no need to change the engine oil, most
electric car owners do not pay attention to
maintenance. Also, as a result of non-compliance
with the rules of battery charging, the loss of
battery capacity after two years of operation is
about 12%. Timely maintenance is required for
the long-term and accident-free operation of the
electric vehicle. Electric cars, in addition to the
power supply, auxiliary and transmission
systems, as well as rechargeable batteries, do not
have
much
poorer
maintenance
than
conventional car maintenance.
Experts recommend checking the condition of the
electric vehicle before each trip and paying
special attention to the condition of the car div
and number plates in general, electrical and
lighting equipment, steering and brakes, sensors,
tires. The planned maintenance is carried out in

order to properly maintain the electric car, to
extend the service life of the vehicle. During the
maintenance process, car service specialists
perform the following tasks:
External inspection of the vehicle;
Inspection of warning and lighting systems;
Control and brake system inspection;
Adjusting the brake system by changing the
technical fluid or refilling it;
Lubrication of components and parts of
electric vehicles;
Recharge or replace the battery;
Tightening the contact connections on the
motor;
Adjust the gap between the contacts;
Cleaning of the cable sheath from the
complications of the work process and the
structure;
Clean the interior from dirt and dust.
The periodicity of maintenance depends on
the operating conditions of the electric vehicle
and the wear of parts. Experts recommend
that electric vehicles be serviced at least once
a year, and in some cases once every six
months. There is also scheduled maintenance
according to the established rules:
After the electric car has covered a distance of
12,000 km, it is necessary to check the coolant
level of the heating and cooling system for the
battery, the power inverter, the charger
module. Specialists will also review the
brakes, suspension, and steering;
It is recommended to change the tires every
15,000 km to ensure uniform wear of tires;
Replacement of the cabin air filter after
50,000 km;
Seasonal maintenance every six months allows
the electric car to be prepared for the new
weather conditions. Materials required for the
maintenance of electric vehicles. During the
maintenance of electric vehicles, there may be a
need for reducer working fluid, brake fluid, multi-
purpose lubricant, air conditioning system
refrigerant, cooling oil for the air conditioning
system. The brake fluid is replaced every two
years or after a distance of 40-60 thousand km.
The antifreeze in the battery cooling system is
replaced every 5 years. It is necessary to use
original quality materials.
C
ONCLUSION
Maintenance of electric vehicles, in comparison
with cars with internal combustion engines, is
distinguished by extended service intervals,
fewer operations, less total time spent in service,
fewer parts and the number of spare parts and
consumables. Taken together, this means
significant cost savings for owners and reduced
revenue for workshops relative to the era of
combustion engines.
During the maintenance of electric vehicles, it will
be necessary to have a short service life, increase
the number of spare parts and materials, and
increase the number of electric car parts stores.
