1. Industry Background

AI-powered toys and educational devices are rapidly becoming mainstream, offering interactive learning,
voice-assistant functions, motion sensing, and smart behavioral responses. The power system behind these products
must support high-performance processing while remaining safe, compact, and child-friendly. Lithium-ion batteries
have become the preferred energy solution due to their long runtime, lightweight form factor, and fast charging
capabilities. :contentReference[oaicite:0]{index=0}

From AI learning robots and smart dolls to AI-enhanced building kits and STEM educational devices, all of these
products rely on continuous, stable power to run sensors, microcontrollers, speakers, wireless modules, and
motorized mechanisms. A well-designed lithium battery pack directly improves user experience, product lifetime,
and safety performance.

As a custom battery manufacturer, PKNERGY focuses on

packs for AI toys and educational electronics, helping brands build reliable and competitive products.

2. Technical Requirements for AI Toys Batteries

AI toys and learning devices typically integrate cameras, microphones, motion sensors, wireless modules (Wi-Fi,
Bluetooth), and small motors. This leads to strict requirements on the battery system:

• Safe chemistry – Li-ion or LiFePO4 chemistry is selected based on application, safety level, and space.
• Long runtime – Children expect AI toys to work for several hours of play or learning per day.
• High peak current capability – Motors and actuators cause short-term current spikes that the battery must handle safely.
• Compact size – The battery must fit into small, irregular toy housings without affecting appearance or ergonomics.
• Multi-level protection – Overcharge, over-discharge, over-current, and thermal protection are essential.
• Stable output voltage – Sensitive voice-recognition chips and wireless modules require a narrow voltage window for reliable performance.

Typical battery configurations in AI toys include:

• 1S Li-ion cells (3.7V) for compact voice-assistant toys, smart dolls, and tablets.
• 2S/3S packs for motor-driven robots or multi-axis motion platforms.
• Custom-shaped lithium-polymer packs designed to fill thin or irregular spaces, often used in
  
  ultra-thin wearable-style devices
  .
• Integrated PCM/BMS for real-time protection, communication, and battery status monitoring.

3. Key Power System Pain Points

When AI toys or educational products enter mass production, engineers usually encounter the following challenges:

• Safety compliance for children’s products
  Batteries must meet strict safety standards and pass drop, vibration, and abuse tests. Cell selection,
  pack structure, and PCM design all affect safety.
• Very limited internal space
  Designers want thin and lightweight toys, but this limits cell size. Custom Li-polymer cells are often needed
  to make full use of every millimeter of space.
• Power spikes from motors
  When motors start or change direction, instantaneous current can be several times the average load. The pack
  must handle this without triggering protection unnecessarily.
• Long standby and low self-discharge
  Many toys are not used every day. A low self-discharge battery keeps sufficient energy even after weeks of
  standby, reducing customer complaints.

By combining the right cell chemistry and a customized protection scheme, PKNERGY helps customers overcome these
typical design bottlenecks and improve both safety and runtime.
