Frequently Asked Questions
What cable length is best for a mobile dc fast charger paired with mobile energy storage in disaster relief?
For disaster relief, a 5m-7m cable is best for mobile dc fast charger paired with mobile energy storage (like guangzhou max power’s bcm series). This length lets you place the mobile energy storage safely away from hazards (debris, floods) while still reaching evs in staging zones. Shorter cables (3m) limit placement, while longer ones (10m) increase energy loss (up to 8%). The bcm series supports 5m as standard and includes a storage reel to prevent tangles during transport—critical for fast disaster response.
How does the BCM series mobile energy storage system ensure connector compatibility with mobile dc fast charger?
The BCM series mobile energy storage system supports universal connectors (type 2, j1772, chademo) for mobile dc fast charger use—via interchangeable heads and a dedicated chademo port. This works with 95% of ev models, so clients don’t need multiple mobile dc fast charger units. The connectors are ip67-rated (dust-tight, water-resistant) and zinc-alloy reinforced, making them durable for harsh relief or construction sites. Wholesalers can offer connector customization if clients need niche types (e.g., tesla ccs).
Can a mobile energy storage system pair with any mobile dc fast charger, or do they need to match?
Mobile energy storage (like the BCM series) should pair with mobile dc fast charger units that match its power output—for the bcm series, 10kw-15kw chargers (11kw is optimal). A 20kw charger will be limited to 11kw (wasting potential), while a 5kw one won’t use the storage’s full capacity (slowing charging). Guangzhou max power provides a matching guide to help wholesalers select compatible mobile dc fast charger units, ensuring optimal efficiency and no damage to either system.
How does the BCM series mobile energy storage system integrate with mobile dc fast charger to reduce energy loss?
The BCM series mobile energy storage system integrates with mobile dc fast charger via a direct dc output port (no adapters) and can bus communication. The direct connection cuts energy loss by 3-5% (vs. adapters), while can bus shares soc data—letting the mobile dc fast charger adjust output to protect the storage battery. For example, it slows charging when storage soc is <20%, extending battery life by 2 years. Wholesalers can highlight this integration to clients wanting efficient, low-maintenance mobile charging setups.
How to solve the problem if the LCD touch screen of mobile energy storage products fails to respond?
First, check if the product is powered on normally; if not, reconnect the power source. If powered on, wipe the screen gently with a clean, dry cloth to remove dust or stains. If the problem persists, press the reset button (usually on the product side) for 3-5 seconds to restart the system. If it still doesn’t work, contact our after-sales team with the product serial number for professional technical support.
Can your mobile energy storage products be used with other brands of charging equipment?
Our mobile energy storage products are designed with universal interfaces that match most standard charging equipment on the market. Before use, confirm that the voltage and current parameters of the external equipment are consistent with the product’s output specifications. Avoid using equipment with mismatched parameters to prevent damage to the mobile energy storage product or the external device. If in doubt, consult our technical team.
What should users pay attention to when storing your mobile energy storage products for a long time?
First, charge the product to 50%-70% of the battery capacity to avoid over-discharging or over-charging during storage. Store it in a dry, well-ventilated environment with a temperature between 10°C and 25°C, away from direct sunlight and high-temperature areas. Check the battery status every 3 months and recharge it to the recommended capacity to maintain battery performance.
Can you provide after-sales maintenance services for mobile energy storage products?
Yes, we offer a one-year free after-sales maintenance service for mobile energy storage products. If the product has quality problems within the warranty period (non-human damage), we provide free repair or replacement of parts. Beyond the warranty period, we still offer paid maintenance services, including parts replacement and system debugging, to ensure the long-term use of the product.
How to update the software of the LCD touch screen of mobile energy storage products?
Connect the mobile energy storage product to a stable Wi-Fi network first. Enter the “Settings” interface on the LCD touch screen, find the “Software Update” option, and click “Check for Updates”. If an update is available, follow the on-screen prompts to download and install it. Do not power off the product during the update to avoid system damage. If you encounter problems, contact our technical support.
