Cargo tricycle electric vehicles are extremely common working vehicles for short-distance urban delivery, transfer at agricultural markets, last-mile courier handover and merchant restocking. Such vehicles excel in load capacity. They carry heavy loads and operate under high-intensity conditions, frequently running continuously on slopes, bumpy roads and in fully loaded states. As the power core of the vehicle, the capacity configuration, discharge characteristics and structural layout of the supporting battery pack directly determine whether the vehicle can steadily fulfill daily operation demands. Given varied load weights, different running ranges and diverse chassis structures, a standard battery with a single specification often fails to fully match actual working conditions. This is why customized battery solutions centered on specific voltage levels are attracting increasing attention in the industry.

　　Many cargo tricycle electric vehicles adopt a 72V voltage platform as the power configuration baseline. Compared with lower-voltage vehicles, a 72V platform can output higher driving power under similar current conditions, which suits cargo vehicles requiring strong power and high climbing capability. At the same time, higher voltage helps reduce cable current for the same power level, lowering cable heating and loss while improving overall drive system efficiency. Under this voltage platform, the battery solution must also be coordinated with factors such as total loaded weight, daily running range and charging conditions, so that the power system matches the working profile of the whole vehicle.

　　The core of a customized battery solution first lies in selecting cell chemistry and capacity configuration. At present, the lithium iron phosphate route is widely adopted for low-speed cargo vehicles. These cells offer relatively stable safety characteristics, long cycle life and controllable thermal runaway risk. With proper heat dissipation design, they suit long-duration, high-current loading conditions. In capacity planning, designers derive the required cell capacity backward from the target driving range, average speed, load weight and road gradient, while reserving a reasonable safety margin to avoid range anxiety during peak seasons and heavy loads. Sensitivity to capacity differs greatly across usage scenarios. High-frequency short-distance delivery and long-distance cross-region transfer call for distinctly different design approaches for battery packs.

　　Next comes the structure and installation method of the battery pack. The chassis space of cargo tricycles is limited. Battery packs usually need to be embedded in the frame or placed beneath the cargo bed. Both the influence of center-of-gravity distribution on driving stability and the convenience of removal and maintenance must be considered. Customized solutions adapt to chassis dimensions, beam structures and reserved wiring interfaces, using layered and grouped layouts to maximize capacity within limited space. Since vehicles work outdoors for long periods and are exposed to dust and possible water contact, shell protection, sealing level and shock resistance must be strengthened. Stable output must be maintained even on bumpy roads and in complex weather.

　　The battery management system is also an indispensable part of customized solutions. Cargo tricycles draw large currents and experience obvious load fluctuations. The management system continuously monitors voltage and temperature of each cell series and executes balancing plus overcurrent, overcharge, overdischarge and high-temperature protection. During frequent start-stop and continuous climbing, heat generation inside the battery pack rises significantly. Sound thermal management design controls cell temperature rise, maintains discharge consistency and extends overall pack life. The management system can also communicate with the vehicle controller, feeding back remaining charge and abnormal warnings to the instrument display, enabling users to understand vehicle status and arrange charging in advance.

　　In customized cooperation, supplier capability assessment cannot rely solely on sample specifications. A reliable project flow should cover requirement analysis, solution design, sample validation, mass production and after-sales support. Early on, the vehicle’s voltage level, target range, charging method and installation space must be clarified so suppliers can output a matching solution. During the sample stage, installation tests must be completed to verify discharge performance, temperature rise and operational stability under actual working conditions. At the mass production stage, process consistency, delivery rhythm and quality control deserve attention. Only with a complete chain can a customized solution truly land rather than stay at the level of laboratory parameters.

　　Operation and maintenance also affect the effectiveness of customized batteries. Cargo vehicles carry heavy loads. Reasonable charging habits should be built according to actual operating intensity to avoid extra loss caused by frequent full charging and full discharge. Charging areas should remain ventilated and away from direct sunlight and high-temperature environments. Connectors, wiring and housing should be inspected periodically to detect loose or damaged parts early. In fleet operation, the data functions of the management system can be leveraged to record charge-discharge cycles, observe cell consistency changes, identify potential issues in advance and carry out preventive maintenance.

　　As demand for last-mile delivery and intra-city freight keeps growing, the installed base of cargo tricycle electric vehicles is rising steadily in suburban and township markets. Market requirements for power system reliability and matching are also improving. Customized battery solutions built around the 72V platform can strike a balance among capacity, structure, protection, management and vehicle working conditions. They help operators lower replacement and repair pressure and improve vehicle availability. When selecting customized suppliers, beyond product parameters, delivery lead time, batch consistency, technical response speed and compliance test documentation are all key evaluation dimensions. Comprehensive assessment is needed to choose a supporting solution that truly fits long-term operation.
