Real-time Overcharge Prevention ‘Smart Control’
Proprietary Algorithm ‘Power Cut-off After Full Charge’,
,
,
, ‘LG Electronics is accelerating the expansion of its electric vehicle (EV) charger business in Korea by equipping slow EV chargers with fire prevention technology.’,
,
, ‘On the 21st, LG Electronics announced that it would apply not only “smart control” but also “power cut-off after full charge” technology to its 7kW slow charger (EVW007SM-SK) to be released in Korea. The company plans to establish a double safety net to prevent fires during charging and alleviate customer concerns.’,
,
, ‘Smart control transmits charging information from the EV battery to a control system, and upon receiving charging control commands from the control system, it immediately stops charging to prevent overcharging. The technology monitors accurate charging information in real-time through powerline communication (PLC) modems in the charger and electric vehicle communication controllers (EVCC) in the EV that communicate via charging cables.’,
,
, ‘It has acquired certification for the standard communication protocols between EVs and chargers, “ISO15118 VAS,” and between chargers and control systems, “OCPP.” With this certification, LG Electronics meets the requirements for the Ministry of Environment’s “Slow Charger Installation Subsidy Program.”‘,
,
, ‘The “power cut-off after full charge” feature prevents overcharging through the charger’s own algorithm in case of communication system errors in the EV, which may lead to failure in receiving battery charging information. It determines charging completion when “power used during charging” is sustained at less than 1W, the lowest measurable power by the charger, for over 30 minutes and then cuts off the charging.’,
,
, ‘All LG Electronics EV chargers control the usage of the top 10 hazardous chemicals such as lead, cadmium, and mercury below the standards set by the European Union (EU) through the Restriction of Hazardous Substances Directive (RoHS) during the manufacturing process.’
