特斯拉‘s energy storage business, powering homes and grids with Megapack and Powerwall systems, delivered a lifeline in a tough first quarter of 2025, raking in $2.73 billion—a 67% jump from last year, according to Business Insider. Yet, while this side hustle cushioned a 20% drop in automotive revenue and a net income plunge to $409 million from $1.4 billion, new U.S. tariffs on Chinese battery components threaten to dim this bright spot for electric vehicle (EV) enthusiasts and Tesla investors alike.

Energy Storage: Tesla’s Unsung Hero

Tesla’s energy division, often overshadowed by its EV dominance, proved its worth this quarter. The Megapack, a massive battery for utility-scale energy storage, and the Powerwall, a home battery for solar integration, drove the segment’s success. “Energy storage saved some pretty dismal numbers from Tesla,” investor Ross Gerber posted on X, highlighting how these systems offset global vehicle sales slumps amid protests targeting CEO 埃隆-马斯克. With 67% revenue growth, the energy business underscores Tesla’s pivot toward diversified energy solutions, a boon for EV owners seeking reliable, renewable power backups.

Tesla’s Energy Surge Masks Auto Woes, But Trump’s Tariffs Loom Large For Ev Owners

Tariff Turbulence Hits Battery Supply

The glow of Tesla’s energy success faces a storm from President Trump’s escalating tariffs on Chinese imports. Tesla’s CFO, Vaibhav Taneja, warned during an earnings call that tariffs will hit the energy business harder than autos, stating, “The impact of tariffs on the energy business will be outsized since we source LFP battery cells from 中国.” These lithium-iron-phosphate (LFP) cells, critical for Megapacks and Powerwalls, rely on China’s dominant battery manufacturing. Tesla assembles these systems in 加利福尼亚州和内华达州 but imports the cells, exposing it to tariff-driven cost hikes. For EV owners, this could mean pricier home energy solutions, potentially slowing adoption of integrated EV and solar setups.

Tesla’s Scramble for Solutions

Tesla is racing to dodge the tariff bullet. Taneja outlined plans to manufacture LFP batteries in the U.S., but equipment shortages are stalling progress. “We’ve also been working on securing additional supply chain from non-China-based suppliers, but it will take time,” he added. Meanwhile, Tesla’s new Megapack factory in Shanghai, near its Chinese EV plant, aims to localize production but won’t fully shield the U.S. market from tariff impacts. Elon Musk, stepping back from his Trump administration role, admitted the tariffs pose a “significant” challenge, advocating for lower duties while acknowledging Trump’s final say.

EVXL’s Take

For EV owners, Tesla’s energy business isn’t just a corporate footnote—it’s the backbone of a future where your car, home, and grid sync seamlessly with clean energy. The tariff threat feels like a gut punch, potentially jacking up costs for Powerwalls that 生产 rooftop solar practical. Yet, Tesla’s knack for innovation, from Shanghai’s new factory to U.S. battery plans, offers hope. If Musk’s team can crack the supply chain puzzle, EV enthusiasts might still charge their lives with affordable, green power. For now, brace for bumps—and maybe check your solar installer’s fine print.
