CTS Low-Temperature Battery Solution

In sub-zero environments, conventional lithium batteries often face capacity loss, reduced power output, charging limitations, and increased internal resistance. CTS provides advanced low-temperature battery technologies designed to maintain stable performance and high reliability even in harsh winter conditions.

1. Intelligent Self-Heating System

Integrated heating films or PTC heating modules
Automatically activates when the ambient temperature is too low
Rapidly warms the battery from below –20°C to its optimal operating range
Ensures safe and reliable charging/discharging in cold climates

2. Low-Temperature BMS Control Strategy

Low-temperature charging protection to prevent lithium plating
Adaptive heating and current-limiting algorithms
Real-time monitoring of cell temperature, heating status, and power output
Balances performance, safety, and efficiency

3. High-Efficiency Thermal Insulation Design

Multi-layer thermal insulation inside the battery pack
Minimizes heat loss in cold conditions
Improves heating efficiency and maintains uniform temperature distribution

4. Comprehensive Low-Temperature Testing & Validation

Cold-chamber tests at –20°C to –30°C
Low-temperature charging and discharging cycles
Long-term durability evaluation of the heating system
Applicable for EVs, commercial vehicles, machinery, and energy storage systems
