Nowadays, it'snot that difficultto assemble a battery pack. It's much more difficult to engineer a quality battery pack that will perform safely and reliably for several years. At SES we've been engineering batteries since 1993 and have atalented staff of engineers dedicated to make sure that the custom made battery we build should exceeds your expectations.

Thats why SES is selective and follow some strict rules to take custom battery projects. Below is the brief layout of custom battery project planning

Feasibility Study :All potential battery projects start with a feasibility study where our sales, engineering and production personnel analyze the Battery Design data provided by the customer. This is the first step to determine if we can provide the product that the customer wants. In some cases the type of cell dictates additional information from the customer to assure this cell can be used safely. At this point we will also determine what agency, compliance and transportation safety testingare required. The two most common reasons to reject a project is not enough space to provide the required watt-hour capacity and unreasonable cost expectations. If the project is feasible we initiate the assignment.

Product Design :Our in house engineering department is staffed by graduate electronic and mechanical engineers and front-end business co-coordinators. This team work with the customer and provide a conceptual battery pack design with an estimated cost including any testing and/or non-reoccurring engineering (NRE) costs if required. Often there is no NRE cost to the customer because we already have a similar design. If acceptable, either a pencil sketch or an AutoCAD outline drawing is created for customer approval. A conceptual prototype may be built at this time. See Prototyping, below. If the customer approves the concept, the terms of sale are discussed including a payment schedule for any out-sourced engineering, custom circuits, injection molding or machining.If custom engineering and mold creation is required, our terms are1/3 to start the project, 1/3 at acceptance of prototypes and 1/3 upon delivery of the completed battery pack. A non-cancelable, non-returnable purchase order may be requested at this time.

Sourcing :During the design phase we try to utilize our extensiveinventory of existing components suitableto achieve thebattery solutionneeded by the customer. In the case of lithium-ion batteries this includes the Protection Circuit Module safety circuit (PCM) and batterycharge statuscommunication circuits if required. We have a list of ISO approved component vendors and sub-contractors for sourcing components that we do not have on our shelf.In the case where we need custom circuit boards or housings we have a strong relationship with our vendors.

Proto-Typing :Every battery pack has two key parameters that need to be approved by the customer.

• Electrical Design :The battery must function andoperate thehost device, as well be able to becharged in caseit's rechargeable.
• Mechanical Design :The battery must physically fit into or on the host device, including, but notlimited to latching mechanisms.

Ineither case, whether it isshrink-wrapped or in acustom housing, the electrical design isof first and foremost concern.We will provide a shrink wrapped prototypevery early in the design stage to validate the electrical parameters (Sometimes withina week unless there is acustom circuit required that needs to be engineered). Once the customer validates the electrical parameters, we can move on to the physical properties. This may take a number of months if there is a custom plastic or metal housing involved. At some point we will haveprototype housings and other hardware items to verify and validate the mechanical design. This may also include prototype circuit boards.Once this second validation process is complete we can go ahead with finalizing the design and bills of material and release the battery to production.

Electronics Programming :Adding aPCM or communication circuitis not as easy as buying them and soldering them in. The chips need to be matched to the battery pack and programmed with the characteristics of thecells to work properly. We have been using Microchip, TI, Seiko, Maxim and others for years, and knowhow to select the best circuit suited for the customers project. Somebattery packs used pre-programmed circuits and others are programmedduring the finalQC process.

Injection Mold Creation :If the battery design calls for a molded case, weuse CNC sonic weldersto bond the case into a completed pack. Theinjection molds aremade in collaboration with our vendors that have their facilities in Ambala Cantt (Haryana). We either use the customers housing drawings or we create the design in house using AutoCAD or SolidWorks software. A conceptual drawing is forwardedto the customer for approval. Upon approval, before any machining is started, we will have a rapid prototype sample made of the housing so the customer can verify the fit into his device.
We also have vendors that are capable of machining a housing out of a block of plastic and others who can form metal housings that can be screwed together. Either way, we can provide the customer with a complete battery pack solution.

SES is having rich technical expertise in battery technology, today SES is playing a key role in the development of Li-ion batteries for Aerospace, Defence, Marine, Medical and other elite markets.

We manufacture, export and supply premium quality Lithium Iron Phosphate Batteries. We are one of the premium Lithium Iron Phosphate Battery Manufacturer in India.

The battery is a key component of the medical equipment that allows healthcare delivery to be run in a much more flexible, reliable and efficient manner. Developments in battery technology enable an increasingly supportive and patient centric service.

Nickel Cadmium (NiCd) is a portable power solution of choice when long life, high discharge rate and extended temperature range is critical. This chemistry offers fast and simple charging, even after prolonged storage.

A nickel metal hydride battery, abbreviated NiMH or Ni-MH, is a type of rechargeable battery. It is very similar to the nickel cadmium cell (NiCd). NiMH use positive electrodes of nickel oxyhydroxide (NiOOH), like the NiCd, etc.

The consideration for primary batteries is clear - combat readiness require immediate response, therefore, immediate availability of full and consistent power, no charging and priming before use - dictates the use of primary batteries that have no voltage delays, even after long storage periods.

SES is offering its product line Solion - a compact, light-weight, rugged and a dependable li-ion battery solution. We had made sincere efforts for an autonyms battery solution Solion for off-grid solar street light and power back-up application.
