Repair and maintenance of hybrids in Warsaw
Hybrid cars differ significantly from cars with conventional internal combustion engines, gasoline or diesel. This means that the approach to their maintenance should also be different. Even today, finding a station where quality hybrid repairs will be carried out in Warsaw is quite problematic. Firstly, the employees of such a car service must have access to 1000 V, issued by the Association of Polish Electricians (SEP). Most importantly, they must have experience working with such cars. The specialists of STS.Parts meet all these conditions.
Types of hybrid cars
A hybrid is a car in which a conventional engine and an electric motor are installed in parallel. Hybrid cars are divided into several classes:
- FHEV - "fully hybrid vehicle". They are charged only from the internal combustion engine and during regenerative charging. As a rule, they have a small range of electric traction - 5-20 km.
- PHEV - "plug-in hybrid electric vehicle". It can be charged both while driving and from a socket, like a simple electric car. Depending on the model, they have a sufficient range, of 40-80 km.
- MHEV - "mild hybrid". It cannot move on electric traction at all, the high-voltage battery is used to drive the starter generator, which starts the internal combustion engine.
- EREV is an extended-range electric vehicle with a conventional engine as an auxiliary for recharging batteries.
STS Electro provides a full range of services for the diagnostics and repair of hybrid cars in Warsaw - all types, models, and brands, as well as electric cars.
The most common hybrid malfunctions
Almost all hybrid cars are made based on conventional cars or using their components, so the characteristic breakdowns in most models coincide with their non-hybrid counterparts. At the same time, there are a number of units that need to be paid attention to by owners of all hybrids.
- Battery packs. Battery degradation is a natural process, so the battery life is limited. Improper operation can accelerate the process of battery failure. STS Electro is engaged in the restoration of hybrid batteries in Warsaw using equipment testers to check high-voltage batteries of its brand. We return the batteries to factory parameters, which ensures their trouble-free service and longevity.
- Electric motors. We have accumulated vast experience in solving problems of electric motors - replacing bearings, and rewinding stator windings according to factory technologies.
- Control electronics. We restore electric motor boards, oxidized contacts, and change blocks.
- Starter-generators of "mild" hybrids. Previously, this unit was considered not suitable for repair, but today STS.Parts specialists successfully restore them and have a base of repaired units for exchange.
For the repair of hybrid cars, we use specialized diagnostic equipment Toyota Techstream, GDS Diagnostic, GM Diagnostic, MaxiSYS, and our own brand MSG Equipment. We give a guarantee for all types of work and used parts - a minimum of six months.
Tips for hybrid owners
Always carefully monitor the information on the dashboard. When error messages appear, do not delay visiting a car service.
When standing for a long time, be sure to start the engine to recharge the batteries. Otherwise, you will need a hybrid battery repair. In Warsaw, this can be done at STS Electro.
Do not leave the hybrid car for a long time at extreme temperatures. In winter - in the cold, in summer - in the sun.
Usually, the air ducts of the high-voltage battery are located next to the rear seat. Do not cover them with covers and be sure to clean them when cleaning the interior and when dirty. Do not allow moisture to enter them.
FAQ - frequently asked questions about hybrids
What is the difference between an electric vehicle and a hybrid vehicle?
An electric vehicle moves only on electric traction, a hybrid uses an internal combustion engine. Without electricity, a hybrid car will drive poorly, but it will get there, without an internal combustion engine - it will not be able to.
How often should the coolant level in a hybrid be checked?>
As often as you can, with any suspicion of leakage or its penetration inside. The condition and level of the fluid depend on the condition of all important units of the hybrid car: the power battery, electric motor, and internal combustion engine.
Do hybrid cars break down less often?
The tendency to breakdowns depends not on the type of car, but on the design features and operating conditions. STS Electro, Warsaw's leading hybrid auto service, advises not to neglect maintenance and diagnostics so that your car always pleases you with the performance, economy, and dynamics inherent in hybrid cars.
Hybrid car service for other cars
Problem: A well-known logistics service provider brought in three electric vans for repair after their high-voltage batteries failed. In one of them, the battery was dismantled.
Problem: The high-voltage battery is discharged and cannot be charged. The car does not accept a charge because the electronics do not recognize the connection of the charging gun.
Problem: A sharp drop in driving range and the vehicle switching to emergency mode with reduced power (“turtle mode”).
Problem: The problem with the car was the incompatibility of the Chinese GB/T standard charging system with European charging stations. This created difficulties for the owner of the Audi Q4 e-tron, since the car, produced for the Chinese market, could not charge at European stations with the required speed and reliability.
Problem: Failure of Toyota hybrid batteries is a common problem that our customers come to us with. The battery cells degrade, making it impossible for the car to operate normally.
Problem: We received an electric car with very discharged traction batteries. The problem is typical for the Fiat 500. During idle time, the batteries discharged below the permissible level, and the car's electric motor stopped starting.
Problem: The Hyundai Kona made a rather loud noise. The customer diagnosed the malfunction on his own - in his opinion, the gearbox was the cause of the extraneous sounds.
Problem: We received an electric motor manufactured by Continental, which was installed on an Opel vehicle for the Chinese market. The motor seized after the car was involved in an accident.
Problem: There was water and rust inside the rail, which damaged both the needle bearing in the cover and the torque sensor, i.e. both the mechanical and electrical parts
Problem: Two electric vehicles arrived at our workshop: a 2018 Kia e-Soul with noise in the motor area and a Mercedes-Benz EQC with an "insulation fault to ground" error. In both cases, the faults turned out to be quite typical and caused by design flaws in the vehicles.
Problem: We received a Hyundai Ioniq EV with complaints of whining noise during driving. An initial inspection revealed that the sounds are coming from the motor, on the side opposite to the gearbox.
Problem: In the case of a critical discharge of a low-voltage battery (12–48 V), the electronics prevent charging because it is dangerous with Li-Ion batteries. The manufacturer recommends discarding fully functional batteries and replacing them with new ones. This is expensive.
Problem: Failure of Toyota hybrid batteries is a common problem that our customers come to us with. The battery cells degrade, making it impossible for the car to operate normally.
Problem: Land Rover Range Rover Sport 3.0 SDV6 Hybrid AT AWD - the hybrid system did not work, the VBB was in emergency mode. The car was running only on diesel fuel, the low-voltage battery was not charging.
Problem: None of the car's systems were working at all, it wasn't even possible to raise it on a lift because the air suspension didn't activate either. I had to install the Porsche near the repair box on "goat" stands.
Problem: In Opel Astra H vehicles, the electric power steering pump often fails. The cause can be either corrosion or damage to the unit due to careless driving.
Problem: IThe specific placement of the steering rack in many Audi models allows moisture to penetrate the control unit of the electric power steering, causing corrosion of components and failure of the unit.
Problem: Steering rack leakage from under the tie rod dust cover
Problem: Steering rack leakage from under the tie rod dust cover
Problem: The owner of a Citroen C4 Picasso car came to us with a complaint about poor engine performance. The car literally could hardly drive: the engine would not rev above 2000 rpm and did not develop the necessary power. Fuel consumption increased significantly. The problem lies in the car's clogged particulate filter.
Problem: We were approached by the owner of a 2017 Citroen Berlingo with complaints of a knocking steering rack.
Problem: A Mercedes-Benz B250 electric vehicle, equipped with a Tesla motor, arrived at the service center with insulation fault errors and coolant ingress inside the electric motor.
