There are many ways to implament a [[WikiPedia:battery pack|battery pack]] or traction pack.  In this article we will try to clarify the distinction between simple, parallel, and hybrid implamentations.  We realize that the use of the word ''hybrid'' may be confusing, especially when you add ''battery pack'', which might seem to describe the standard traction battery in a hybrid vehicle rather than a particular type of battery pack configuration.

A '''simple''' pack consists of a '''single series string''' of batteries or cells, this is by far the most common type of battery pack. If no other modifier is used to describe a battery pack you can usuaily assume it is a single simple string. Ideally the individule batteries are chosen such that a single string of them will satisfy all the requirements of a projects design goals.  However there are instances in which a satisfactory battery is not available to meet all of the demands, or there may be other reasons to use a more complex battery pack configuration.

==Parallel==
+
== Reminder Light Reset ==
−
In the EV world with regards to battery packs '''Parallel''' usually indicated parallel strings of batteries. They might be disconnect able or hard wired but probably don't have any advanced electronics between them.  There are special considerations to observe with regards to the interconnects such that one strings total resistance is as equal as possible to the other. Such parallel strings are usually made up of the same type of batteries. They are normally designed to share the load equally and are used to either increase the available power or energy content of the pack.

==Hybrid==
 
−
A '''Hybrid''' battery pack is to advanced a setup to be simply called parallel. It would likely be made up of two strings of roughly equivalent voltage, but may be entirely different chemistries or even use caps as one of the strings. There would usually be a DC-DC device between the pack or some other way to manage the flow of power from one string to the other.  Such a Hybrid Battery Pack is used to take advantage of the strong points and mask the weak aspects of the various strings that make up the whole. Similar to reducing engine size and making up for it with electric motors as is done with hybrid vehicles.  One might have a high capacity but low power string and a low capacity but high power string and combine them in a manner to utilize both of these strengths and eliminate the weaknesses.

With regards to the Prius, a parallel pack might describe using additional stock batteries which are always connected. Though such [[Prius_EV_Mode_Button#Parallel_Packs|projects exist]] using both stock NiMH and PbA chemistries most do not grid charge their parallel packs.

Rons original [[PriusPlus]] and the [[EDrive]] systems do not use a parallel nor hybrid type pack, rather these implementations replace the stock battery with a simple  string, though they may be capable of switching back to use the stock string the two are not used at the same time. An advantage of this implementation is that there is no chance of damaging or degrading the stock battery pack which could be removed for weight and space savings or even sold to offset the conversion costs. If the stock battery is removed than it's replacement must be as robust in order to prevent failures, this can be mitigated by leaving the stock battery in place such that it can be used should the need arise.

The [[Hymotion]] system may ''(I'm speculating)'' be using a Hybrid Pack which is made up of the stock NiMH string and an additional Li-ion string with some level of management between them.  Such a hybrid setup has also been suggested by a number of EV folks as they have discussed and even implemented such setups for use in pure EV's over the years. Some benefits of such an implementation may include simplicity of installation as there is no need for a [[Battery Tap Emulator]] as the existing battery and it's taps are used.   [[State Of Charge Manipulation]] may still be required utilizing [[State Of Charge Drift]]. Drawbacks might include the need to keep the stock battery which might not be ideal for the tasks of a [[PHEV]] and there may be lighter batteries which could better utilize the space which the stock battery occupies. Though there is a risk of damaging the stock battery, such an implamentation should actually reduce the load and number of cycles to which the stock battery is subjected, thus further extending it's service life.

===Theory of Operation===
+
== Disabling Traction Control ==
−
In short a new larger capacity ''(source)'' battery pack and ''[[Battery Chargers|charger]] device'' would float charge the stock ''(target)'' battery pack at a voltage near the top of it's normal operting range, taking care to consider regeneration headroom. A contactor based setup might simply parallel a properly sized source pack with the target on a SOC based duty cycle, additionally a large resistor might be used to limit the current transfer when the source pack is fully  charged and the voltage differential is at it's greatest.  Such dump charging is simple and effective but can also be risky if not properly configured.  A DC-DC converter or DC input charger with load following capabilities might also be used to continuously replace the energy removed by the motors while taking care to not overcharge the target battery pack.  It's important to keep the stock battery pack at a voltage which corresponds to a high, yet not full [[SOC]].  The charger would also need to stop discharging the source battery pack when it reaches a particular desired SOC. Once the source pack is depleted the vehicle should revert to normal operation using only the original battery pack. A properly configured Hybrid Battery Configuration will exploit the [[State Of Charge Drift]] portion of the vehicles battery management routines in order to accomplish [[State Of Charge Manipulation]]. The use of a [Battery Tap Emulator]] should not be nessecary with these implamentations.

It forces the ICE to run continuosly and defeats the traction control system.  Normal operation returns after turn off and reboot.  Unlike EV-Mode this is '''strictly a diagnostic function and should not be used under normal situations'''.  Thanks to Peter Rawlinson for posting this on the [http://autos.groups.yahoo.com/group/Prius_Technical_Stuff/message/13315 Yahoo Prius_Technical_Stuff] group.  More discussions can be found here: [http://priuschat.com/Thinking-about-disconnecting-traction-control-t12860.html], [http://autos.groups.yahoo.com/group/Prius-2G/message/46367], [http://autos.groups.yahoo.com/group/toyota-prius/message/90032].

Disabling Traction Control

WARNING: The shop manual apparently states in no uncertain terms that this procedure must NOT be used to drive the car as damage to the transmission could occur due to traction control being defeated.

  • Follow the sequence below (quickly - within 60 seconds)
  • Set Ign switch to ON, not READY (Power button twice, no brake)
  • While still in "P" fully depress the gas pedal two times.
  • Select "N" fully depress the gas pedal two times.
  • Select "P" fully depress the gas pedal two times.
    (LCD display will indicate a !Car! in upper left corner of screen)
  • Turn key directly to "start" to start the engine (brake+start button)

It forces the ICE to run continuosly and defeats the traction control system. Normal operation returns after turn off and reboot. Unlike EV-Mode this is strictly a diagnostic function and should not be used under normal situations. Thanks to Peter Rawlinson for posting this on the Yahoo Prius_Technical_Stuff group. More discussions can be found here: [8], [9], [10].

Disabling Navigation Lock-Out

When moving faster than a very slow speed, many of the navigation setting buttons are disabled (grayed-out). This sequence will override the lock-out until the car is powered off.

  • Press the "Menu" button (hardware button)
  • Press the "Voice" icon on the display
  • Press the upper left corner of the display, where the speaker icon is
  • Press the lower left corner
  • Press the upper left corner again
  • Press the lower left corner again
  • The screen should change to a diagnostic screen
  • Hold the "Override" button for several seconds until it changes to black
