The global transition to zero-emission public transport is accelerating the adoption of electric bus fleets. Today, a growing number of transit applications — including electric city buses, electric school buses, and inter-city electric coaches — are shifting to safer, more durable, and cost-effective lithium iron phosphate battery technology.

With advanced thermal management, robust structural design, and strong OEM capabilities, CTS Battery provides customized high-voltage lithium battery solutions tailored to the specific energy, voltage, and space constraints of each bus model.

• Reliable daily operation under high-cycle usage (up to 4000-6000 cycles)
• High safety with LiFePO4 chemistry — no thermal runaway
• Wide voltage platform compatibility (307V–800V)
• Seamless integration with electric drivetrains and existing BMS communication (CAN/RS485)

Whether you are operating an electric city bus fleet or developing a new electric bus model, CTS helps you build a safe, high-performance, and long-lasting transit power system.

Electric buses face continuous vibration, high current charge/discharge, wide temperature variation, and long daily operating hours. Our high-voltage battery pack is engineered with an IP67-rated enclosure, vibration-resistant construction, and robust cell mounting to withstand the toughest on-road conditions.

Unlike NMC or other lithium chemistries, LiFePO4 (LFP) offers exceptional thermal and chemical stability. It significantly reduces the risk of thermal runaway, making it the preferred choice for public transit where safety is the top priority.

Built-in intelligent Battery Management System ensures:

• Overcharge / over-discharge protection
• Active/passive cell balancing
• Temperature monitoring and thermal management
• Short circuit and overcurrent protection
• Real-time SOC / SOH monitoring via CAN / RS485

We understand that each electric bus has unique power requirements. That’s why we offer:

• Voltage options: 307V / 400V / 460V / 576V / 666V / 768V / 800V and custom
• Capacity options: 60kWh / 100kWh / 150kWh / 200kWh
• Liquid cooling and optional liquid heating
• CAN / RS485 communication protocols
• IP67 and higher IP ratings upon request
• Size and structure tailored to bus chassis layout

• Electric City Bus
• Electric School Bus
• Inter-city Electric Coach
• Transit Bus Fleet Energy Storage

At CTS Battery, we don't just supply batteries — we provide complete high-voltage power solutions for the electric bus industry. If you are developing or upgrading an electric bus fleet, choosing the right battery partner is critical.
