Tesla founder Elon Musk took the stage at D today to talk about his company’s plans, but didn't expect to get egged into making an early announcement: the company is going to triple the size of its Supercharger charging station network by the end of June, for the first time letting drivers make it from Los Angeles to New York in one of its electric vehicles. Also, according to Musk, the Supercharger network will cover most of the major areas of the US and Canada by the end of the year. Short range and a lack of fast charging stations have been among the biggest criticisms of electric vehicles, and the dramatic expansion could be a boon for adoption.

Things have been working out financially for the automaker as well. Earlier this month, Tesla turned its first profit, and even managed to pay back its $465 million government loan ahead of schedule. If you're hungry for more details on Tesla's Supercharger expansion, Musk says the company will be making a formal announcement tomorrow, including a map containing the locations of the new stations.
