Hybrid Repair Shop & Maintenance

This inverter unit controls the electrical power flows to and from the batteries, the electric motors, the generators and the AC air compressor for Hybrid air condition 
The Toyota inverter unit contains 2 inverter circuits and a converter / voltage controller.
The power inverter converts the DC voltage of 201.6 volts to an alternating voltage of 500 volts for the electric motor. The small inverter provides the Hybrid AC compressor power supply for Prius  air conditioning. The DC / DC converter takes care of the 12 Volt for the battery.

 

How does the Power converter / inverter look inside? To give you an idea, here are two pictures of the Prius 1 converter / inverter

 

 The Hybrid Battery

The THS II Prius Hybrid battery is of nickel metal hydride type (NiMH).
This is a extremely powerful  hybrid battery has a weight of almost 100 lbs
Toyota hybrid battery currently has the highest power density among hybrid batteries

The Prius HV battery consists of:

28 Modules
6 Cells per Module
168 Cells Total
1.2 Volts per Cell
201.6 Volts Total
6.5 A / H (3h)

The HV battery is placed on the bottom plate above the rear axle of Prius. The charging level of the HV battery is held by the computer system between 40% and 80%, which means that Toyota follows a car alarm. There is therefore a full factory warranty of 8 years.
The lifetime of the HV battery in the Prius has been tested in various ways by means of lifetime simulations, but in practice.
The HV battery has been tested at taxi companies in Japan, Sweden and Canada.

Toyota Prius Charging level indicator 

The charge level of the HV battery is maintained by the control software at a level between 40% and 80%. As an indication for the current level, an icon in the energy plate is placed on the central display. This icon indicates the level between 40% and 80% by means of bars. There is also a color indication.

 

Green is above the norm – The computer system will limit the charging of the HV battery, also limit regenerative power generation and even completely stop at the highest permitted charging level. As far as possible, energy will be extracted from the battery for the drive.

Blue is within the norm – All regenerative energy can be discharged towards the HV battery and the battery can and can provide maximum power for the drive.

Pink is below the standard – The withdrawal of power from the HV battery for the drive is limited and completely stopped at the lowest permissible level.Also, the combustion engine will no longer switch off, but ensure a charging current through the generator to the HV battery.

In an intermediate phase, both electrical power can flow to the HV battery and to the electric motor for the drive.This process is regulated using a number of parameters, such as generated electrical energy (MG1), energy required for the HV battery (charge level), NiMh temperature and required electrical energy for the drive (MG2).

Prius 12 volts battery

 

The Toyota Prius has a 12V – 35 Amp / hr lead / cadmium Battery, this battery provides the power supply of the control, control and control systems.This battery is in the luggage compartment and is not just auxiliary battery but essential for the proper functioning of the Prius.
The auxiliary battery is charged from the HV battery via the converter. Loading starts when the hybrid system is started via the Powerbutton. The combustion engine does not need to be in operation for this purpose. 

The Prius Inverters / Converter

Power Inverter The power inverter of the Prius is an electrical converter that converts the DC power of the HV battery and the AC voltage of MG1 and MG2. The inverter consists of two 3-phase bridge circuits, one for MG1 and one for MG2, each circuit consists of 6 power pulses and converts the DC power of the HV battery into a three phase AC voltage and the alternating AC voltage of MG1 and MG2 in a Direct voltage. The activation of the power transistors is controlled by the HV-ECU. This sends a control signal to the power transistors. In the inverter there are a number of sensors / sensors that send information about the supplied power, voltage level, temperature to the HV-ECU. The inverter in the Prius II is also equipped with a voltage amplifier circuit which increases the input voltage (201.6 volts) of the HV battery to an output voltage of up to 500 volts for MG2. The inverter controls the voltage level based on the power requested by the HV-ECU between 201.6 volts and 500 volts, thus keeping the current to MG2 equal. The inverter produces quite a lot of heat during these control operations, so that it must be cooled by a separate and internal cooling circuit together with MG1 and MG2.

 

nverter-2

 There is also a separate second and smaller inverter circuit, this circuit converts the 201.6 volt DC power from the HV battery to a 201.6 volt AC voltage for the air conditioning compressor.

 

The Hybrid Converter

 The Prius II converter is placed in the lower part of the compact housing. The converter is responsible for converting the 201.6 volts DC from the HV battery to 12 volts DC for the charging of the auxiliary battery

The 201.6 volts are initially converted by a power transistor bridge cc to 201.6 volts AC, then transformed to a lower voltage by a transformer, then converted into and DC voltage by a rectifier circuit.
The converter also controls the function of the voltage regulator, the voltage level of the auxiliary battery, is controlled and maintained by the converter. The charging of the auxiliary battery is thus not dependent on the incineration of the internal combustion engine. The charging of the auxiliary battery begins when the hybrid system is activated using the power button.

Toyota Hybrid Battery

A closed NiMh battery is mounted for the power supply of the drive via the MG2 electric motor. The HV battery is placed in the rear area on the bottom plate above the rear of the Prius. The battery is equipped with a separate cooling system with fan and is cooled from the interior with suction air. The closed NiMh battery of the Prius II is loaded by MG1 and the regenerative brake system (MG2).

Battery and Ecu charge levels and condition of the HV battery are monitored. Battery-Ecu receives various status signals from the HV battery, such as the battery temperature, outdoor temperature, voltage level of each module, and power to and from the HV battery.
The Battery-ECU checks the process of charging and charging the HV battery and the required cooling. The Battery-ECU communicates continuously with the HV-ECU. The Battery-ECU sends charging / discharge signals to the HV-ECU. The HV-ECU keeps the charging state at the desired level by calculating the load and discharge amp and, if necessary, adjusting the hybrid drive status. The HV-ECU control is configured to keep the charging level of the HV battery as much as possible between 40% and 80% to ensure a long battery life. If the battery pack temperature becomes too high, loading / unloading is limited or interrupted and an alarm is generated.

Prius Engine repair

 

 

 

 

 

Toyota promises that the Prius offers the same comfort and very smooth rides, in the city drive Toyota Prius surpasses that promise thank to the perfectly silent electric motor. But on the highway, the Prius offers great comfort, the car glides like a true limousine on the highway. The new EGR system allows for the recovery of heat from the exhaust gas stream. this allows for a shorter pre-heating time of cooling system of the internal combustion engine, so it has been previously heated up. therefore, the engine may stop earlier. in additional, there is faster heat available for heating the interior. the EGR system. increases the efficiency of the overall hybrid drive relative to the drive in Prius 2

 

 

 

 

The new power control unit inverter/converter is more compact design and direct cooling of the IGBT power transistors. the converter increase the voltage of 201.6 volts DC to 650 volts and a second DC/DC converter. increase the voltage of 201.6 volts DC to   650 volts DC and a second DC/DC converter converts the 201.6 volts into 12 volts serving charging the 12-volts auxiliary battery.

Rebuild prius Hybrid battery

 

 

 

at Toyota Prius repair shop we rebuild your existing Prius battery pack, the new battery pack of the Prius 3 consist of 28 module of 6 cells of 1.2 volts. each module provides a voltage of 9.6 volts. the total connected load of the battery pack is 201.6 volts. the total maximum peak power of the new battery pack is 27kw (36hp)How you can damage hybrid battery pack of gen 3 Toyota Prius.Damage to the hybrid battery pack can be caused by too long to continue driving in EV mode. in a normal situation, the computer will turn off The EV mode when the charge level of hybrid battery becomes too low. the battery pack should adequately protected by existing  security measures in the logic according to Toyota against deep discharge. in some cases it appears that the security is not enough.sometimes there will merely and the driver can override this to continue driving the electric motor. for more information for hybrid battery please contact us 

Prius Auxiliary battery

if the charge level of the auxiliary battery is too low, eg by self-discharge, the Prius 12v battery will be discharge in a month, a battery should never be fully discharge. 11.5 volts is a safe limit, stronger discharge leads to defects at 10.7 volts. the battery is clinically dead. the problem with lead acid batteries applies to all cars and of course not only Prius.

Problem Arise when a low charge level of the Prius Auxiliary battery getting lower

-The Prius fob does not open only the diver side

-all the electrical system are dead. the Prius is not starting

-the auxiliary battery is not accessible, because the rear door is not open

-the Prius is not going to move because parking brake is on

the Prius can be jump by using the jump start terminal and a second battery, the terminal is located under the hood in the box on the right side.

After taking my 2007 Prius to the Toyota dealership and being quoted an extremely high price for the repair, I thought that my Prius was totaled. However, after looking online we found Ken and decided to take a chance. He ended up being able to fix it for half the price and a better warranty. He finished on time and even did more work to the car for free. Ken was a pleasure to work with and I will definitely be taking my car there for future repairs. I would highly recommend this place!read more

2005 Prius- 159,000 miles While parallel parking last week, I kissed the curb with my passenger’s side rear bumper. It dislodged several supportive clips, showing about two inches of clear space on one side. I shook my head as the bumper was still attached but looking for a railroad track to tear it off. I called Ken at the Prius Repair Shop for advice. He asked several questions to make sure the car was drivable and the bumper wasn’t dragging the ground. He then asked me to bring it in the following day. I did, and he called back after lunch and said it was ready. Ken reattached the bumper with new clips and said, "no charge" as it only took several minutes to fix. For the last two years I’ve had Ken perform regular oil and filter changes, a tune-up, and replace the inverter and water pump. Ken is honest, understands the complex Prius Hybrid system, and does what he say he will do.read more

I just picked up my car from here, and I just want to say that all these 5 star reviews are well-earned!!!! I am so thrilled with the exceptional service I received and the quality of care. I didn't feel I was overcharged as I have with many countless other mechanics in the past, and my prius went from sounding like a jackhammer and a jar of crickets were jammed under the hood to being as silent as a snail!!! They didn't try to sell me a bunch of unnecessary junk, they didn't make me feel like an idiot, they were just kind and gracious and it's safe to say I won't ever be going anywhere else for maintenance! THANK YOU!read more

Ken is the best mechanic I know. I have been bringing my cars to repair for over 10 years now. I won't go anywhere else! I had a 1988 mercedes and now I have a 2001 toyota camry. Ken has helped me keep my cars running! I commute all the way to Laguna Hills since he is a very trust worthy mechanic. He is quick to finish any job that is necessary and will listen to anything that you may have a concern with. He is very friendly and I highly recommend for anything from oil checks to assisting with smog checks. There is a certified smog check right next door, so very convenient if you are needing to do that too!read more

This shop is absolutely amazing. I am so grateful to have found Ken. He is hands down the best mechanic I’ve been to. Very honest, and knowledgeable which is a rare thing in and of itself in this industry. My engine was making weird noises and I was taking it from one mechanic to another for diagnoses and estimates. I was not happy with anyone’s answers or integrity up to this point which led me to call Ken, whom I came across through a referral from a friend. When I first called him and told him the engine problem I was having with my Prius he asked me a couple questions and diagnosed the problem immediately which no one was able to do before. He didn't even hesitate. Based on the content of the questions, the speed to which he got right to the heart of the issue and his kindness, right there I knew he knew his stuff, he wasn’t going to take advantage of my situation and that's when I started to relax that I was finally in good hands. When I brought my car in he looked it over, confirmed his diagnoses and then spent hours trying every trick in the book to see if there was any way to save my engine. As it turns out my engine was failing due to other mechanics mishandling that I had been taking it to. Unfortunately it was too far gone at that point and I needed to make plans to replace it. Ken got to work and found a remanufactured engine for me at a very fair price, installed it and had my car back to me without any hiccups and in a very short timeframe. Ken is hands down THE expert when it comes to Prius hybrids. I will be taking my car to him for routine maintenance I don't want anyone else working on my car after this engine ordeal. There's no one like Ken you truly are in the best of hands with him.read more

Prompt, friendly and fast service. Ken responded to my inquiry quickly and scheduled me to come in the next day. My check engine light was on. Ken checked it and told me instantly what need to change in my car. He was able to turn it around that same day. Ken also checked in to see how my car was running. Very happy with the experience. Will continue to go there & refer my friends.read more

Awesome service! Quick turn around time, and fair pricing. Can’t really ask for more than that when it comes to prius maintenance or repairs! I will forever go to ken for all of my prius problems or maintenance that needs to be addressed. I had to have a few parts replaced on the prius and the dealership quoted me an astronomical price. After speaking with ken on the phone, I was educated on what exactly went wrong with my prius and what my options were to cut corners on cost. Bottom line! If you have a prius and don’t take it here you’re a fool.. Thanks ken, be seeing you in the future! -Paulread more

Ken at Caspian took the time to explain my options. He squeezed me in on a busy day, and did the work for the quoted price, far less than I would have spent at the dealership. I'm confident they know what they're doing, and will definitely go back and refer to friends and family. read more
