Prius Hybrid Battery

In general Toyota Hybrid Prius Battery life is starting to weaken when the fuel economy deteriorates this is the first sign of Prius battery failure.All batteries wear out over time, but several factors effect when that happens first is battery chemistry, the second number of charge and discharge cycles, the third temperature extremes, even humidity. average Toyota Prius life is around 10-year,

Prius Hybrid BatteryHow do we rebuild Toyota Prius hybrid battery repair at Prius repair shop?

A) we test to see if the Hybrid battery computer is faulty. If it is still working perfectly you will have no error icons and messages after the Toyota Prius hybrid battery is reconditioned. We check if there is any additional error to make sure that the Prius hybrid battery will operate normally in every aspect. B) We strip out the Toyota Prius hybrid battery pack as seen in picture and discharge them individually. This is necessary for the Toyota Prius battery life.

C) We then charge the cells individually over on our special programmable on a preset charging regime, maintaining constant current and monitoring the temperature. This is necessary to remove cells that are faulty from the Toyota Prius hybrid battery pack, and to rebuild lost capacity in fixing the Prius hybrid battery repair. D) We use desulphators in the charging process to assist in the restoring of lost capacity. E) After charging Toyota Prius hybrid battery we test each cell for voltage attained and internal resistance to make sure the remaining Prius battery life F) We stress test each cell with 100 amps current in.This will ensure that each string will survive the load required by the electric motor.. G) All faulty cells are replaced. For the Toyota Hybrid battery repair we take the car or “Prius hybrid battery” for a test run to balanced and equalize all cells and to ensure that the Prius hybrid battery pack is performing normally.

H) We can now rebuilt tubes by spot welding good cells. This solves the problem of finding good tubes. With this we will be able to keep the series 1 Prius running for a very long time to come.Warranty Each Prius hybrid battery after reconditioning is tested in a Prius hybrid battery to ensure that it is operating correctly and that it will perform under,

The Module of Hybrid battery repair

Toyota Prius uses prismatic NiMH modules from Panasonic. Each module consists of six 1.2 V cells connected in series. The module has a nominal voltage of 7.2 V, capacity of 6.5 Ah, weighs 1.04 kg, and has dimensions of 19.6mm(W) x 106mm(H) x 275mm(L). Further notable features are as follows:

A thermal well on top of the cell allows measurement of an approximate internal temperature of the electrolyte,
A hydrogen vent provides for release of hydrogen through a manifold under gassing conditions,
Terminals on each side provide clean connections, – Tie down bolts secure the modules to structural supports,
A plastic case lowers mass, and – The side surfaces of the module provide air gaps for airflow created by dimples and protrusions when two modules are stacked. This Panasonic design has improved in specific energy and power capabilities over the first generation cylindrical cells that are in the 1997 – 1999 Japanese Prius hybrid battery repair.
The Pack of Hybrid battery repair

Toyota Prius Generation II battery stack consists of 28 prismatic NiMH modules connected in series. It delivers a nominal 201.6 Volts and has a 6.5 Ah capacity. The modules are stacked side by side and then compressed together in a rigid, non-expandable structure that prevents expansion from internal pressures. Prius hybrid battery repair, the complete batteryhybrid-battery-replacement-orange-county pack consists of the battery stack, enclosure for structural support and airflow, In Prius hybrid battery repair electronic control unit/monitor, relays and safety switch. The weight of the complete battery pack is 45 kg. The pack is horizontally positioned in the boot of the vehicle partially under the back seat. Power electronics Prius hybrid battery repair (inverter, DC-AC converter) are under the hood and a blower for moving air and associated air ducts are in the boot. Discharge power capability of the Prius hybrid battery pack is around 20 kW at 50% SOC with regenerative capability of 14.5 kW at 2C. The power capability increases with higher temperatures and decreases at lower temperatures in Prius hybrid battery repair. Active thermal management can improve power capability at lower temperatures.

The Toyota Prius Battery Pack Thermal Management

The purpose of a Prius hybrid battery thermal management system is to keep the batteries cells operating within a desirable temperature range; prevent the batteries from exceeding a high temperature limit that can damage the batteries and/or reduce life; and maintain battery temperature variations to low levels to prevent highly imbalanced batteries. Pack imbalances can reduce performance and can also damage the battery and/or reduce life. Thermal management of the battery pack is typically accomplished with the combination of two approaches. First, a cooling/heating system is designed to extract/supply heat to the Prius hybrid battery repair pack. Second, the battery controller adjusts the vehicle’s use of the battery pack based on the conditions in the batteries.

Forced Air System to increase Toyota Prius battery life

The Prius supplies conditioned air from the cabin as thermal management for cooling the Prius hybrid battery. The pack’s forced air system consists of two vents located in the cabin under the middle brake light (exhaust from the cabin or inlet to the pack); ducting to the Prius hybrid battery repair pack enclosure; the enclosure manifold; air gaps between modules; ducting out of the pack to a blower that pulls the air through the system; and two exhausts (one to the boot and the other to the outside). In Prius hybrid battery repair, A hydrogen vent from each module is connected in series with tubing. Any gases released are exhausted from the vehicle through the gas manifold to avoid any increased hydrogen concentration and, thus, potential for explosion. Outside air is conditioned (heated or cooled) by the vehicle’s thermal comfort system to a level comfortable for the driver. This approach has the advantage of providing air that is not only comfortable to the passenger(s), but also ideal for use in heating or cooling the NiMH batteries. However, the Prius hybrid battery does not use the forced air for heating the batteries. To achieve a relatively uniform temperature distribution across the modules, a parallel airflow scheme is used, rather than a series configuration. In a parallel configuration, each module is set up to receive the same amount of airflow and thus the same cooling. To achieve this in the Prius hybrid battery, cabin air enters the pack through a plenum that runs beneath the battery stack horizontally from passenger side to driver side. The cross-sectional area of the plenum is largest at its entrance and linearly decreases as it goes under the modules. Then the air flows vertically through the gaps between each module (formed from dimples and protrusions on side walls). Finally, the air enters into the top plenum. This plenum’s cross-section increases linearly in the direction of the flow. With this design, the pressure drop across each module is expected to be uniform and, consequently, should lead to a uniform flow rate around each module. The air is drawn by a 12 V blower installed above the driver’s side rear tire well. The air is either exhausted to the boot or through a vent on the driver’s side C-pillar. The fan has four settings, depending on the maximum temperature of four monitored batteries. Toyota also monitors the inlet and outlet air temperatures. The fan settings are off, low, medium, and high speed. The blower setting depended on temperature and transitions with hysteresis depending on whether temperature is increasing or decreasing,

The Prius hybrid battery has a computers that’s solely dedicated to keeping the Prius battery at the optimum temperature and optimum charge level. Both these functions maintain and increase Toyota Prius battery life. Prius hybrid have lab data showing the Prius hybrid battery can do 180,000 miles (290,000km) of normal driving with absolutely no degradation of the battery’s performance.long Toyota Prius battery life is largely due to the computers control of the Battery pack.

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 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 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 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
