Energy Storage System

Composition and Chemistry:

Traction batteries are typically composed of multiple cells arranged in series and parallel configurations to achieve the desired voltage and capacity. The most common types of traction batteries include lithium-ion, nickel-metal hydride, and lead-acid batteries. The choice of chemistry depends on factors such as energy density, weight, and cost.

Voltage and Capacity:

Traction batteries are designed to provide a specific voltage, referred to as the traction voltage. This voltage level is crucial for the proper operation of the electric propulsion system. The capacity of the battery, measured in kilowatt-hours (kWh) or ampere-hours (Ah), determines how much energy the battery can store and, consequently, the range the electric vehicle can achieve on a single charge.

In TVS-RIG, the voltage can be set between 60V DC and 1000V DC to simulate different types of traction voltage systems. To operate TVS-RIG, always assume it is live with high voltage until proper safety measures have been secured.

Charging and Discharging:

Traction batteries can be charged through external power sources such as charging stations or regenerative braking systems. The ability to discharge energy efficiently is essential for providing the necessary power to drive the electric motor. The charging and discharging processes should be managed within specified voltage and current limits to ensure the safety and longevity of the battery.

Thermal Management:

Traction batteries generate heat during charging and discharging cycles, and efficient thermal management is crucial to maintaining optimal performance and preventing overheating. Many traction batteries are equipped with cooling systems to dissipate heat and ensure the battery operates within a safe temperature range.

Safety Features:

Traction batteries incorporate various safety features to prevent overcharging, over-discharging, and other potentially hazardous conditions. These features may include temperature sensors, voltage monitoring systems, and sophisticated battery management systems (BMS) that regulate the charging and discharging processes and with the safety feature to generate and monitor HVIL (Hazardous Voltage Interlock Loop).

Installation and Maintenance:

The OEM instruction book should provide guidelines for the proper installation of the traction battery in the electric vehicle. It should also include information on routine maintenance procedures, such as checking and maintaining the battery's state of charge, inspecting for physical damage, and ensuring proper connections.

TVS-RIG utilize a 250A fuse / service disconnect that is installed to separate battery modules, to lower traction voltage level when traction voltage battery is decommissioned.

Lifecycle and Recycling:

Traction batteries have a limited lifespan, and the OEM instruction book should offer guidance on the expected lifecycle of the battery. Additionally, information on proper disposal and recycling procedures should be provided to promote environmental responsibility.

By understanding the functions and features the Traction Voltage Battery, users can safely and effectively operate around electric vehicles.
