With the heatwave upon us, quickly check out this “Summer Heat‑Related Charging Safety Guide.”

Summer mode has officially kicked off, and scorching heat is upon us! Every year during the summer, overheating‑related charging malfunctions and safety incidents are all too common. For the vast majority of new‑energy vehicle owners, the sweltering weather not only puts driving and riding comfort to the test but also constantly challenges the endurance limits and safety performance of both the vehicles and their charging infrastructure.

In fact, topping up your car’s battery during the summer involves a few little tips that are easy to overlook. Today, we’re stepping into the role of “Summer Charging Concierge” and presenting this guide to safe charging in the heat, sharing four super‑practical charging hacks to help your battery stay healthy all summer long!

01 Allow it to cool at room temperature; avoid replenishing energy immediately.

After a long drive or when your vehicle has been exposed to intense sunlight, don’t rush to charge it! At this time, the battery’s internal temperature is soaring; charging immediately can place excessive stress on the cells, triggering thermal‑protection mechanisms and accelerating the aging of both the wiring and the battery itself, posing safety risks. We recommend letting the engine idle for 15–30 minutes after turning off the ignition, allowing the battery temperature to return to its normal range before recharging—this approach safeguards both driving safety and battery longevity.

02 Choose the right time to say goodbye to high-temperature charging.

Be sure to avoid the peak heat hours between 11:00 a.m. and 4:00 p.m., when solar radiation is strongest and surface temperatures are at their highest. Charging during this period doubles the difficulty of battery heat dissipation, sharply increases charging‑station energy consumption, and significantly reduces charging efficiency; over time, this can even cause irreversible damage to the battery cells. Instead, prioritize charging in the early morning, late afternoon, or overnight—when both the charging station and the battery operate under lighter loads, charging efficiency is higher, and off‑peak nighttime electricity rates can help you save on your power bill.

03 Shallow charging and discharging—say no to “full load”

In high-temperature summer conditions, the internal chemical activity of a fully charged battery intensifies, making it highly susceptible to issues such as swelling and capacity degradation. For everyday commuting, it’s advisable to keep the battery level within the optimal 20%–80% range; this not only reduces internal stress but also significantly slows down capacity fade. Only when preparing for long-distance driving or highway trips should you charge the battery to 100% in one go.

04 Properly Combining Fast and Slow Charging

On hot days, try to avoid frequent use of high‑power fast charging, as it generates significant heat and can degrade the battery over time. For everyday home‑to‑work charging, prioritize slow charging; reserve fast charging for emergencies or when you need a quick boost. A balanced approach is the best way to prolong your battery’s life.

While paying attention to charging habits, a reliable charging device remains the cornerstone of safe high‑temperature energy replenishment. As a locally rooted enterprise based in Luoyang and deeply committed to the new‑energy sector, Kuqi Jianeng leverages over a decade of industry expertise and a core R&D team of master’s and doctoral degree holders. The company focuses on the research, development, and manufacturing of EV charging stations, energy storage systems, battery‑swap solutions, and integrated solar‑storage‑charging systems, harnessing end‑to‑end technological capabilities to build a robust safety barrier for summer‑time energy recharging for car owners.

The company’s full range of national‑standard charging equipment—including single‑unit dual‑gun DC chargers, single‑unit four‑gun DC chargers, and heavy‑truck chargers—operates within a temperature range of –30°C to +55°C and features an IP55 high‑protection rating, ensuring reliable performance even under intense summer sun and harsh weather conditions. Equipped with an intelligent air‑cooling system, it automatically derates output in high‑temperature environments, continuously monitors battery and charger temperatures, and instantly cuts power in the event of abnormalities, effectively eliminating safety risks at the source.

In addition to its hardware advantages, Kooqi has developed a proprietary charging‑cloud platform that enables real-time monitoring of all equipment status, 24/7 intelligent supervision, and proactive fault alerts, ensuring early detection and timely resolution of potential issues. Complemented by a dedicated on‑site operations and maintenance team, we deliver an ultra‑fast response within 30 minutes. Whether you’re a private commuter, part of a public‑transport, logistics, or heavy‑truck fleet, or a commercial‑industrial customer looking to build a comprehensive energy‑replenishment station network, we offer end‑to‑end services—including customized equipment solutions, manufacturing, installation, and ongoing operations and maintenance.
