EAA PHEV Battery Management Systems
August 10, 2008 - 9:30pm — David HerronAn overview of BMS's written up by EAA PHEV members. A Battery Management System (BMS) is some sort of system for managing the health of the many batteries in an electric vehicle. A BMS can range from a human with a multi-meter, to more automated regulation or power shutteling system. The Battery charger is generally considered a seperate device though it will most likely need to intigrate with whichever BMS is used.

Battery regulator
August 9, 2008 - 9:02am — David HerronA battery regulator is a device in a battery pack which bleeds off excess charge current to allow all cells or batteries in a string to be fully charged without overcharging other cells. Since they may all reach full charge at different times because of differences in capacity due to age, a regulator keeps all the batteries or cells in balance. They are most effective during periodic full charge events performed to PbA battery packs by holding down the finishing voltage preventing weak cells from overcharging and gassing. Regulators do not actively balance batteries by shuttling power during operation like a battery balancer does. A battery balancer may further extend a pack's lifespan.
Regulators are most often used in BEV battery packs to prolong the packs' useful lifespan.

Battery Management Systems: Design by Modelling (Philips Research Book Series)
January 26, 2008 - 7:15am — David Herron | Battery Management Systems: Design by Modelling (Philips Research Book Series) author: H.J. Bergveld W.S. Kruijt P.H.L Notten asin: 1402008325 binding: Hardcover list price: $199.00 USD amazon price: $105.47 USD |
Battery Management Systems - Design by Modelling describes the design of Battery Management Systems (BMS) with the aid of simulation methods. The basic tasks of BMS are to ensure optimum use of the energy stored in the battery (pack) that powers a portable device and to prevent damage inflicted on the battery (pack). This becomes increasingly important due to the larger power consumption associated with added features to portable devices on the one hand and the demand for longer run times on the other hand.
BattEQ
January 17, 2007 - 9:52pm — David HerronThe BattEQ line of charge equalizers improve performance and extend life for battery-powered equipment. It uses a patented energy shuttle process to restore and maintain proper charge balancing across a battery string. Depending on the application, BattEQ can increase life by 30 to 500%.
BattEQ is a non-dissipative circuit that precisely balances charge in series strings of rechargeable batteries while avoiding traditional wasteful overcharge equalization. Charge equalization is an essential element of effective battery management. BattEQ provides a precise, modular, low-cost solution that applies to all major battery chemistries.
BattEQ has proven to be very effective with lead acid batteries in many applications. It also works with lithium-ion (Li-Ion) batteries and is being tested with nickel metal hydride (NiMH). It has great significance for Li-Ion batteries because overcharge equalization does not work and Li-Ion cells are much more expensive than lead-acid. Essentially the same BattEQ unit suffices for any battery chemistry.
