Battery Technology Not Only For Vehicles


Coda Automotive, a division of Coda Holdings, had previously planned to make its electric sedan available to the general public in the next month. This may take a backseat as its parent company, Coda Holdings, has announced it would be focusing its efforts on another related technology, stationary batteries for electricity storage.

The battery technology for the company would start by making minor modification for battery packs to its cars. The batteries are lithium iron phosphate cells made in China. The company then either sells them individually or in a bundled package that can be used to store solar power for excess power from the individual’s solar array. With the extra power, companies are able to reduce their peak load leading to lower overhead costs for electricity for the consumer.

Since the company has designed the electric packs for cars, these arrays are easily transportable and can be modified either up or down. The giant’s car division has designed its sedan around a battery pack that is able to store 31 to 36 kilowatt hours. With the expansion into the stationary module product line, the battery is able to store at least forty-kilowatt hours.

The company seeking expansion into stationary battery packs is entering a lucrative sector of the market. These battery arrays can be used as back up electricity sources because the demand far outstrips the supply. The idea of this lateral expansion is to support the electric car market as battery sources for electrical power would be available and thus lower demand for the new electrical power increases as more electric vehicles go online.

According to Edward A. Solar, Senior Vice President of Coda Energy, “We are leveraging this technology across business units as it is synergistic for us.” Coda Energy would be the division that focuses on stationary batteries of the future.

The company further adds the use of batteries in stationary service would help in the reduction of global warming emissions. In the stationary market, the electricity produced from large-scale solar farms would be stored and eventually bought and sold freely in the market. These batteries are designed to provide high levels of electricity, as the current design is able to handle 100 kilowatts or 134 horsepower.

The larger battery array for cars has also become attractive for grid use. One other firm has entered the market for large storage batteries and this is A123 Systems. Their largest array is located in Elkins, West Virginia and has cells smaller than a D cell flashlight battery pack.

Electricity Giant Partners with EV Carmaker


General Electric Energy had announced last Wednesday that the company’s 240-volt wall-mounted WattStation electric vehicle charging unit would be the standard charger for the upcoming electric vehicle from Coda.

In its statement, the electricity giant called Coda, a start-up company, as a leading electric vehicle manufacturer despite the fact that the company still has to roll out an actual electric vehicle. This partnership though is a positive sign for the car maker’s future, where its unveiling has been marred with delays and further delays.

In the same announcement, Coda announced that the production of the Coda electric sedan was underway. It also included a price dip by as much as $5,000 from the previous estimates for the purchase of the Coda sedan.

According to CEO of Coda, Philip Murtaugh, the price of the upcoming sedan was down to $40,795 through examination of each line item in building the vehicle. There was also a marked improvement in quality and presentation of the vehicle and was proven with the vehicles displayed, with more comfortable seats and better fitting door panels. The Coda sedan was originally a four seater but the latest reincarnation seats five people comfortably.

GE’s participation would be through the energy charging facilities for the Coda electric sedan’s 36 kilowatt-hour battery. The byline in the Coda electric sedan is its bigger battery compared to its competition. This battery pack is 50 percent larger than the Nissan Leaf, thus, allows the Coda to run for 120 miles compared to the Leaf’s 80 miles on a single charge. Coda’s onboard charger claims to be twice faster than the 2011 Leaf’s charger.

These though are claims made by Coda and are still unproven. The fact though that GE is willing to package its home charger with Coda, together with the lower price of the sedan, makes it impossible not to ruffle many feathers in the small but highly competitive electric vehicle market.

This is just one step in the corporate goals of maintaining all core design and engineering work internal to the company and establishing partnerships with manufacturers and suppliers around the world. These partners include BorgWarner, UQM Technologies, EnergyCS, Continental Automotive Systems, Porsche Design Studios, Delphi, Celgard, Novolyte Technologies, OMITEC, Lear, Hella, Hafei and Lishen. Overall, Coda maintains over thirty separate relationships with companies and partners in four continents across the world.
