Tesla is to acquire Maxwell Technologies, in a deal that values the California-based ultracapacitor firm at around US$218 million.

Maxwell said on 4 February the companies had entered into a definite merger agreement under which Tesla would buy the company's 45.9 million shares for $4.75 a share in an all-stock transaction. The deal represented a 55% premium to the share price, which closed at $3.07 on 1 February.

The merger is expected to be finalised in the second quarter of 2019 or shortly after, subject to the successful tender and exchange of shares, regulatory approvals and customary closing conditions.

Maxwell 48V ultracap module

Ultracapacitor maker Maxwell Technologies (Maxwell) has introduced an enhanced 48V ultracapacitor module product, which includes the firms’ DuraBlue new shock and vibration cell technology.

The module is designed for mass transportation such as the integration in hybrid bus propulsion systems or rail stabilisation systems.

According to the California-based company, the module combines Maxwell’s solvent-free dry electrode formation and manufacturing process with a patent-pending cell structure design, which results in an increase in vibration immunity of 300% and in shock immunity of 400% compared to competitive offerings.

The product also comprises of a capacitor management options system for reliability and safety including a redundant over-voltage alarm.

“Ultracapacitors’ rapid charge and discharge characteristics, long operating lifetime, wide operational temperature range and ruggedness make them an ideal energy storage solution for hybrid buses and other vehicles that employ braking energy recuperation systems,” said Franz Fink, Maxwell’s president and CEO.

The module has been validated through several months of sampling with selected customers.

In November, the United States Advanced Battery Consortium selected Maxwell to research the technological and economic feasibility of a 12V hybrid energy storage system consisting of lithium-ion batteries and the company’s ultracapacitors.

Celadon, Maxwell Technologies partner to deploy ultracaps in remote controls for set top boxes

Wed, 09/25/2013 - 11:22 -- Editor

Maxwell Technologies is working with remote control manufacturer Celadon to provide its 10-farad (F) HC series ultracapacitors.

The ultracapacitors will be used with the CLS-140 Cellular Media Center from set top box developer Cobalt Labs. These set top boxes are used by telecom companies including Orange.

Each remote control has a USB port that is plugged into the set top box to charge the ultracapacitors through AC wall power. Maxwell claims the ultracaps can deliver a quick 70 to 80% charge to the remote control within four to five minutes.

Michael Griswold, vice president of sales and business development at Celadon, said, "Ultracapacitors, as an alternative to traditional alkaline batteries, are a compelling solution for remote controls, as well as many different types of handheld devices.”
