Although several customers have approached Beckett requesting a custom battery pack, most found our off-the-shelf module a faster and less expensive solution.   We do configure the software for each pack application and are able to provide physical product alterations as well as custom software, hardware and packaging for batteries.  Please “Tell Us”  about your application.

Today only in North America, outside of Cleveland in North Ridgeville, OH. (map) Beckett’s products contain globally sourced components including key items from our facility (Beckett Asia Pacific Co. Ltd) near Beijing China.   As customer demand increases in other world areas (Asia and Europe) we will establish additional manufacturing centers within other Beckett affiliate facilities to more effectively serve local markets.

The cost (price from Beckett Energy) is significantly less than the cost of developing a custom battery pack.  Starting with development time and engineering, Beckett has already performed the work to have an off-shelf-solution which functions “out-of-the box”.   These internal costs are amortized across all the modules sold.   Materials cost to Beckett are lower than a custom product.  Beckett has negotiated the best prices based on our total volume across our entire portfolio of products including electronics, metal and plastic components.  Standard work, vertical integration and automation keep the modules labor content to a minimum.  Labor cost is typically higher in low volume custom battery packs.  The good news is as your volume increases, Beckett provides increased price discounts.   Please refer to our Markets and Applications section and Case Studies.

Li-on Battery Module and Battery Pack Questions and Answers (12)

Typically large format batteries are made by connecting smaller battery cells into series and parallel combinations to achieve a greater amount of energy capacity and voltage.  An electric vehicle battery would be considered a large format battery.   The United Nations defines a “large” Lithium ion battery in the UN38.3 procedure as one with a gross mass of more than 12 kg.  From a battery industry perspective, Beckett considers its module as a large format 1.1kWh battery, but since its weight is approximately 8 kg, it complies with the more extensive test criteria of “small” batteries including the 150G shock test.   Hence it’s “small” in size but “large” in terms of capacity.

Beckett offers a standard, off-the-shelf product available to be configured into the desired sized battery pack. With its modular design and flexible battery management system / controller, there is no need to develop expensive custom battery packs over one (1) kilowatt hour of energy and 24 volts DC. This is a tested, qualified commercialized product; not a proof of concept, or a prototype.  The module and BMS can ordered under part numbers 8224S-XXX and 84BMS-XXXX and be able to ship via any conventional means. (See also Li-ion Battery Shipping Questions and Answers).

The maximum storage capacity of each module is 1.1 kWh / 42.4Ah at 100% DOD; the nominal value.  To maximize the life of each lithium-ion module, the voltage range of the cells are slightly limited to 88% DOD providing 885Wh / 34.7 Ah of available capacity.

The Beckett model 8224S module has a maximum continuous charge current of 21.2Adc.  While Beckett 24V lithium-ion module has a very wide operating temperature range, the charge current is limited at low temperatures (0 to -20°C).  When charging is completed, the charging source should be disabled or disconnected; continuing to trickle charge a fully charged lithium battery module is not recommended.    For more information on charging please refer to the “Operating Manual for Advanced Battery Storage Units” part number 61906.

DC to DC charging is presently the fastest technology available today to charge lithium-ion batteries, as in Electric Vehicles.   In general, the chemistries of Lithium-ion batteries allow them an overall faster charging rate than traditional lead acid batteries.   The Beckett 24 Vdc module has a maximum continuous charge current of 21.2Adc.  The charge current is limited at low temperatures (0 to -20°C).    For more information on charging please refer to the “Operating Manual for Advanced Battery Storage Units” part number 61906.

Wikipedia defines a battery management system (BMS) as any electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its Safe Operating Area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and / or balancing it.   Beckett Energy Systems advanced technology batteries are managed, protected and controlled by an external BMS, model number 84BMS.

The Model 8224S lithium-ion battery module incorporates two levels of protection.  Internal to the module, the software, electronics and circuit protection provide for the safe and optimum operation of the battery cells, and monitor voltage and temperatures.  Separate from the module, the external BMS / Controller model 84BMS provides automatic module balancing and controls voltage, temperature, and current of the entire battery pack.    Communication message sets include: State of Charge (SOC), Condition Status and Alarms, Sleep / Wake Up Commands and Serial Identification.  Please see our battery module Product Overview section for a complete list of battery module functions.

Yes, Li-ion battery packs using Beckett 8224S advanced battery modules require an external pack level BMS (Beckett model number 84BMS) to ensure safety and long life performance of the battery pack.  The BMS / Controller also provides a variety of communication methods to other devices. Please see our BMS Product Overview section for a complete list of battery management functions.

The 8224S battery module is ideally suited to construct larger battery packs. The 8224S is a nominal 24 Vdc battery module.  Modules or parallel strings of modules can be connected in series using available power cables to meet the voltage requirements of the battery pack.   For example four (4) modules in series (4 X 24vdc) = 96 Vdc nominal.  Please see our Specification section for specific voltage range information.

In order to manage the individual battery modules within the pack, the 84BMS is required.   The BMS will control wake up/start up, balancing functions, report overall pack status and pack capacity and assist with the charging function.   Please consult with Beckett Energy Systems prior to attempting to assemble a battery pack.  Please “Tell Us”  about your application.

Please note: All safety instruction and product warning information should be adhered to and are listed in the “Operating Manual for Advanced Battery Storage Units” part number 61906.

The 8224S battery module is ideally suited to construct larger battery packs. The 8224S‘s maximum energy storage capacity (at 100% Depth of Discharge – DOD) is 1.1KkWh or 42.2Ah.  Modules can be connected in a parallel, series, or a combination of parallel and series  wiring configurations to meet the capacity requirements of the battery pack.   For example two modules in parallel by two modules in series (2P2S) would provide a 48Vdc system with 4.4kWh / 85Ah maximum capacity battery pack.  Other considerations:  In order to extend the life of battery packs, Li-ion battery modules should operate at a less than 100% DOD.   For example at 88% DOD, the available energy capacity of a four  module pack is 3.5 kWh.   Please see our Specification section for module capacity information.   One will also need to consider overall system efficiency, desired cycle life, as well as optimization of charge and discharge rates when determining the required capacity of Lithium-ion battery packs.

In order to manage the individual battery modules within the pack, the 84BMS is required. The BMS will control wake up/start up, balancing functions, report overall pack status and pack capacity and assist with the charging function.  Please consult with Beckett Energy Systems prior to attempting to assemble a battery pack.  Please “Tell Us”  about your application.

Yes, this is the preferred method of engaging with customers.  From working with you to understand requirements, the correct configuration of battery modules and BMS can be assembled into a functioning pack.  Based on application experience, Beckett engineers will use lab equipment or your actual products to simulate the load, provide test data, and make recommendations for charging/rectification and/or power conversion. Please “Tell Us”  about your application.
