Selecting a range extended energy storage system supplier requires evaluation of technical capability, delivery reliability, and after sales support. Injet HanCang operates as a range extended energy storage system supplier serving commercial, industrial, and utility customers across multiple continents. The company provides complete systems including battery, generator, inverter, and controller as a single packaged solution. This article presents the supplier evaluation criteria, product portfolio, and service offerings from Injet HanCang.
A range extended energy storage system supplier must meet specific criteria to serve industrial customers effectively. Injet HanCang recommends that buyers evaluate potential suppliers on five dimensions. The first dimension is technical capability, including the ability to size systems correctly for specific load profiles. The second dimension is manufacturing quality, demonstrated by test data and certifications. The third dimension is delivery reliability, measured by on time shipping performance. The fourth dimension is after sales support, including remote monitoring and spare parts availability. The fifth dimension is financial stability, ensuring the supplier will remain in business for the warranty period. The table below shows how Injet HanCang performs against these criteria based on customer survey data from the past two years. Evaluation Criteria Injet HanCang Performance Industry Average Technical proposal accuracy 94 percent load prediction accuracy 86 percent On time delivery 96 percent of orders 89 percent First year support response time 3.2 hours average 7.5 hours average Spare parts availability 98 percent in stock 85 percent in stock Warranty claims processed within 30 days 92 percent 78 percent These survey results position Injet HanCang as a range extended energy storage system supplier that meets or exceeds industry averages across all evaluation criteria.
As a range extended energy storage system supplier, Injet HanCang offers a complete product portfolio covering different power and energy scales. The portfolio includes standard products available from stock and custom products built to order. Standard products ship within four weeks. Custom products ship within sixteen weeks. The table below lists the standard product line. Product Name Battery Energy Generator Power Inverter Power Typical Use Case RESS Compact 150 150 kilowatt hours 50 kilowatts 100 kilowatts Small retail RESS Compact 300 300 kilowatt hours 100 kilowatts 200 kilowatts Office building RESS Industrial 600 600 kilowatt hours 200 kilowatts 400 kilowatts Factory RESS Industrial 1000 1000 kilowatt hours 300 kilowatts 600 kilowatts Data center RESS Heavy 2000 2000 kilowatt hours 500 kilowatts 1000 kilowatts Mining site Each product includes the Injet HanCang control platform with remote monitoring. Additional options include supercapacitor interface, solar charge controller, and custom paint colors.
A range extended energy storage system supplier must provide verifiable performance data. Injet HanCang publishes test results for each product family based on third party witnessed testing. The RESS Industrial 600 system underwent a one hundred hour continuous test at a certified laboratory. The system maintained output voltage within plus or minus two percent of nominal across load variations from twenty percent to one hundred percent. The generator started within eleven seconds on all test cycles. The battery state of charge estimation error remained below two percent throughout the test. The system efficiency measured at the point of common coupling was eighty seven point four percent for a typical daily cycle with two generator starts. The RESS Heavy 2000 system was tested for thermal performance at forty five degrees Celsius ambient. Battery cell temperatures remained below thirty eight degrees Celsius with the cooling system operating at seventy percent capacity. The generator compartment temperature reached fifty two degrees Celsius, below the sixty five degree limit. The system passed a seventy two hour continuous operation test without any thermal derating.
Operating as a range extended energy storage system supplier provides Injet HanCang with data from hundreds of installations. Analysis of support tickets reveals common issues and their solutions. The most frequent support request relates to state of charge calibration drift. After six to twelve months of operation, some systems show state of charge error of five to eight percent. The solution is a monthly full charge cycle where the generator runs until the battery reaches one hundred percent and the controller resets the state of charge reference. Injet HanCang now includes an automatic calibration reminder in the control software. The second most common support request concerns generator starting failures in cold weather. Diesel generators require glow plug preheating below five degrees Celsius. Some installations omitted the preheat circuit. Injet HanCang now includes automatic preheat as a standard feature on all systems destined for regions with winter temperatures below freezing. The third common issue is communication loss between the controller and the remote monitoring server. Cellular signal strength varies by location. Systems installed in areas with weak cellular signal receive a satellite communication option.
A range extended energy storage system supplier provides services beyond hardware delivery. Injet HanCang offers five service tiers. The basic tier includes remote monitoring and software updates. The standard tier adds annual performance reporting and telephone support. The premium tier adds on site inspection every six months and priority spare parts shipping. The enterprise tier includes a dedicated support engineer and guaranteed four hour response time. The custom tier allows customers to select individual services a la carte. Service pricing starts at two thousand dollars per year for basic tier on a five hundred kilowatt hour system and scales with system size. Injet HanCang also provides extended warranty options beyond the standard five year warranty. Extended warranties are available in one year increments up to ten years total. The extended warranty covers all components including the generator, which is typically excluded from standard battery warranties. Pricing for extended warranty is three percent of system cost per year for years six through ten.
As a range extended energy storage system supplier, Injet HanCang maintains a spare parts inventory for all systems sold in the past seven years. The spare parts warehouse in Jiangsu contains six hundred line items including control boards, current sensors, contactors, and generator starter motors. The fill rate for spare parts orders is ninety eight percent within twenty four hours. Emergency orders ship within four hours. The table below lists common spare parts and their typical lead times. Spare Part Typical Failure Interval Stock Level Express Shipping Lead Time Generator starter motor 2000 hours 50 units 24 hours Battery management slave board 5 years 100 units 24 hours Current sensor 8 years 200 units 48 hours Cooling pump 15000 hours 80 units 48 hours DC contactor 10000 cycles 150 units 24 hours Controller power supply 50000 hours 60 units 24 hours Maintenance support includes remote diagnostics to identify failed components before dispatching replacements. Injet HanCang engineers can access system logs remotely with customer permission. The remote diagnostic service has correctly identified the failed component in ninety two percent of cases, reducing unnecessary site visits.
Injet HanCang differentiates through vertical integration of battery, generator, and controls. Most suppliers specialize in only one component. The integrated approach allows Injet HanCang to optimize the complete system rather than assembling third party components.
There is no minimum order quantity. Injet HanCang sells single systems to end users and large quantities to distributors. Pricing is volume dependent with discounts starting at three systems per order.
Injet HanCang partners with equipment financing companies to offer lease and loan options. Terms range from two to seven years. Credit approval is required for financing. Leasing is available for customers outside China through local partners.
Yes, Injet HanCang can adjust component sourcing to meet local content requirements for specific tenders. Additional documentation and verification testing may increase lead time by four to eight weeks.
Injet HanCang provides a five day training course at the Jiangsu facility covering system operation, fault diagnosis, and component replacement. Online training modules are available for free. On site training at customer locations is available for groups of five or more.
