Beyond the Lithium Battery, Key Components from Korea
GM is crediting various affiliates of lithium battery supplier LG Chem for helping it develop the new 100% battery electric Chevrolet Bolt for 2016. “General Motors set aside traditional vehicle development to create the Chevrolet Bolt EV, which can travel more than 200 miles on a single electric charge,” states a release.
GM cites “an unprecedented supplier relationship combining expertise in infotainment, battery systems and component development with GM’s proven in-house capabilities in electric motor design, battery control, system validation and vehicle body/system integration.”
GM worked with LG Electronics Vehicle Components and such entities as LG Chem, LG Innotek, LG Display and LG Electronics, to help develop the Bolt EV. “LG Electronics has invested more than $250 million in an engineering and manufacturing facility in Incheon, Korea, to support the component development and manufacturing for Bolt EV components,” GM says.
From Motor to Dashboard
Components and systems from LG include the Chevy Bolt’s
- electric drive motor (built from GM design);
- power invertor module (converts DC power to AC for the drive unit);
- on board charger;
- electric climate control system compressor;
- battery cells and pack;
- high power distribution module (manages the flow of high voltage to various components);
- battery heater;
- accessory power module (maintains low-voltage power delivery to accessories);
- power line communication module (manages communication between vehicle and a DC charging station); and
- instrument cluster and infotainment system.
“Chevrolet needs to be disruptive in order to maintain our leadership position in electrification,” Mark Reuss, GM executive vice president of global product development, purchasing and supply chain, said in a release.
“By taking the best of our in-house engineering prowess established with the Chevrolet Volt and Spark EV, and combining the experience of the LG Group, we’re able to transform the concept of the industry’s first long range, affordable EV into reality,” he said.
Tech’s Contribution to Transport
“Being selected as GM’s EV technology partner positions LG as a key player in next-generation vehicular technologies,” LG Electronics Vehicle Components president and CEO Woo-jong Lee says in GM’s Bolt release.
“The opportunity to work with GM on such game-changing technology is indicative of exactly the type of contributions that traditional tech companies can make in the automotive space,” he said.
Volt to Bolt
GM says that it relationship with LG began in 2007 when LG Electronics was tapped for the vehicle communications module for OnStar, GM’s telematics system. LG Chem was chosen as the sole supplier of battery cells for the first-generation Chevrolet Volt, which launched in 2010.
LG has since delivered more than 23 million cells with less than two problems per million cells for the first-generation Chevrolet Volt. The subsequent broader agreements for the Bolt EV mark “the first time that GM integrated a full EV component supplier so early in vehicle development.”
