Tesla’s new CyberTruck has entirely eliminated the traditional 12V low-voltage power network in favor of an all-48V configuration. While this is likely the end game for most automakers, power modules enable an immediate, easy transition to 48V—retaining all reliable, legacy 12V devices— while planning for the 48V vehicle of the future.New 48V vehicles don’t need a separate 12V battery to support lower-voltage systemsVicor power modules convert high-voltage from the EV's battery to usable levels for devices on board.Electric power module supplier Vicor Corp. is pointing out that automakers can enjoy the benefits of 48V electric systems in their vehicles without immediately replacing the many familiar 12V devices employed in their cars.Tesla’s new CyberTruck has entirely eliminated the traditional 12V low-voltage power network in favor of an all-48V configuration. While this is the likely end game for other automakers, those companies will want to take time...
Different brands of electric bicycles come with matching original chargers. If consumers use mismatched counterfeit chargers, it will not only damage the battery, but also pose a great safety risk of fire and explosion. Recently, a gang has been prosecuted by Jiangsu procuratorial organs for producing and selling counterfeit electric vehicle chargers.In August 2022, Mr. Wang from Yangzhou, Jiangsu spent 15 yuan online to purchase a certain brand of electric bicycle charger, but during the charging process, he discovered a problem.Mr. Wang, a citizen of Yangzhou: Not only does it feel hot, but it also has bulges. Later, he asked the store to return it, and after returning it once, he found that this situation still exists.Mr. Wang felt that he might have bought counterfeit goods, and he had previously seen a fire accident caused by charging in the news. Realizing the seriousness of the situation, he chose to call the police.After receiving the alarm, the police first contacted the manu...
