Electric flat carts can indeed be fast-charged, but it’s not as simple as “plugging in for quick power.” There are key considerations regarding equipment configuration, cost, and safety guidelines. This article comprehensively breaks down relevant knowledge about fast-charging electric flat cart batteries, helping you use the equipment safely and efficiently.
While electric flat cart batteries support fast charging, two core conditions must be met:
- Fast-Charge Compatible Battery Type: Not all electric flat cart batteries can handle fast charging. Among mainstream lead-acid and lithium-ion batteries, lithium-ion batteries (e.g., lithium iron phosphate) offer better fast-charge compatibility. Some high-quality lead-acid batteries also support fast charging, but you must confirm the battery specifications in advance (via the product manual or by consulting the manufacturer) to avoid damaging the battery due to blind fast charging.
- Specialized Fast-Charging Station Installation: Ordinary household or industrial slow chargers cannot achieve fast charging. An additional dedicated fast-charging station is required. Such stations have an output power 3-5 times that of regular chargers, reducing charging time from the traditional 8-12 hours to 2-4 hours. However, the equipment purchase and installation costs are relatively high (a single fast-charging station typically costs tens of thousands of yuan, and it needs to match the factory’s electrical load). It is suitable for scenarios with high-frequency use and strict requirements for transportation efficiency (e.g., 24/7 continuous production factories).
-
Misconception 1: Leaving the power plugged in for a long time does not affect the equipment Even though chargers automatically power off after the battery is fully charged, prolonged connection keeps the charger in standby mode, which not only increases electricity costs but also accelerates the aging of internal components, shortening the charger’s service life. It is recommended to unplug the power within 1 hour after full charging.
-
Misconception 2: The faster the fast charging, the better Some users believe that higher fast-charging power is better, but excessively high power can cause the battery temperature to rise sharply. Long-term use of such high power can reduce the battery’s cycle life (e.g., frequent fast charging of lithium-ion batteries may shorten their lifespan by 30%). It is advisable to charge within the fast-charging power range recommended by the manufacturer and avoid modifying the charger to increase power without authorization.
-
Misconception 3: Fast charging should only be done when the battery is completely dead Fast charging immediately after deep discharge places additional stress on the battery. Especially for lead-acid batteries, over-discharging can cause plate sulfation, affecting capacity. It is recommended to start charging when the remaining battery power is 20%-30%, which ensures charging efficiency and protects the battery.
-
Misconception 4: Full-load operation immediately after fast charging Batteries are relatively hot after fast charging. Immediately putting them into heavy-load transportation will further increase battery heat, potentially reducing battery performance. It is recommended to let the battery stand for 30 minutes after fast charging to allow the temperature to return to normal before use.
In addition to fast charging, electric flat carts also support slow charging and battery swapping. Different scenarios suit different methods—here’s how to choose based on your needs:
-
Scenarios for Fast Charging:
- Factories with 24/7 continuous production, where electric flat carts are used frequently and require quick energy replenishment;
- Urgent heavy-load transportation tasks where traditional slow charging cannot meet time requirements;
- Sufficient budget and factory electrical load to support fast-charging station installation.
-
Scenarios for Slow Charging:
- Daily transportation tasks are not urgent, and daily usage time is ≤ 8 hours;
- Battery type is ordinary lead-acid battery with poor fast-charge compatibility;
- Limited budget, prioritizing low-cost use (slow chargers cost only 1/5-1/3 of fast chargers and cause less battery damage).
-
Battery Swapping Mode:
-
For high-frequency use scenarios, the “battery swapping mode” is also an option—prepare 2-3 sets of backup batteries. While one set is in use, the others are charged, and the battery is directly replaced when depleted, eliminating waiting time for charging. This method’s cost falls between fast and slow charging, and it avoids battery damage from fast charging, making it suitable for users who require both efficiency and battery lifespan.
